    2015-04-01

    Full Text Available Global trade has an important characteristic in terms of open global markets by means of eliminating barriers to trade and investment. The United States and the European Union, two major international actors and competitors in the economic field, have both the opportunity to change the global trade by concluding the negotiations of the Transatlantic Trade and Investment Partnership. For this reason, this paper tries to find the connections between global trade and transatlantic competitiveness in the way that the global trade can be considered a key to transatlantic competitiveness. The United States and the European Union are global actors and competitors in the global economy and the play field is the global trade. In order to be aware of the importance ofglobal trade in the transatlantic competitiveness, this paper includes also an analysis of the concrete actions that both economic powers are taking in key-sectors of the transatlantic economy.

  17. Measures of International Manufacturing and Trade of Clean Energy Technologies

    Energy Technology Data Exchange (ETDEWEB)

    Engel-Cox, Jill; Sandor, Debbie; Keyser, David; Mann, Margaret

    2017-05-25

    The technologies that produce clean energy, such as solar photovoltaic panels and lithium ion batteries for electric vehicles, are globally manufactured and traded. As demand and deployment of these technologies grows exponentially, the innovation to reach significant economies of scale and drive down energy production costs becomes less in the technology and more in the manufacturing of the technology. Manufacturing innovations and other manufacturing decisions can reduce costs of labor, materials, equipment, operating costs, and transportation, across all the links in the supply chain. To better understand the manufacturing aspect of the clean energy economy, we have developed key metrics for systematically measuring and benchmarking international manufacturing of clean energy technologies. The metrics are: trade, market size, manufacturing value-added, and manufacturing capacity and production. These metrics were applied to twelve global economies and four representative technologies: wind turbine components, crystalline silicon solar photovoltaic modules, vehicle lithium ion battery cells, and light emitting diode packages for efficient lighting and other consumer products. The results indicated that clean energy technologies are being developed via complex, dynamic, and global supply chains, with individual economies benefiting from different technologies and links in the supply chain, through both domestic manufacturing and global trade.

  5. Technological Intensity and Patterns in Slovenian Merchandise Trade

    Directory of Open Access Journals (Sweden)

    Stefan Bojnec

    2006-03-01

    Full Text Available This paper analyses the technological intensity of industries classified by technology levels (low-technology, medium-low-technology, medium-high-technology and high-technology and patterns in Slovenian merchandise trade developments between and within industries in the post-independence years since 1992. Merchandise trade flows by industries are rather homogeneous in the extent of a decline in the external trade integration measured by intra-industry trade indices and in the presence of relative trade advantages. More considerable differences are found in trade structures and trade quality using the ratio of export to import unit values. In exports we confirm the climbing-up technological development approach, including the jump-up in the medium-high-technology industries in the non-EU-15 markets. Medium-low- and medium-high-technology industries experienced greater price competitiveness in trade with the EU-15 countries. High-technology industries and to a lesser extent low-technology industries experienced a greater competitiveness in the EU-15 internal and external trade. These similarities and differences imply implications for industries with different technological intensity, which are associated with trade and policy shifts before and after the accession of Slovenia to the EU.

  11. Does AFTA Create More Trade for Thailand? An Investigation of Some Key Trade Indicators

    Directory of Open Access Journals (Sweden)

    Piriya Pholphirul

    2010-04-01

    Full Text Available This paper examines whether the ASEAN Free Trade Agreement (AFTA creates trade for Thailand or actually diverts it away from the country. It does this by analyzing various trade indicators: the Export Similarity Index, the Intra-Industry Trade Index, and Revealed Comparative Advantage (RCA rank correlation. By examining the patterns of trade between Thailand and other members of ASEAN, it reveals a high degree of similarity regarding the trade structure between Thailand and AFTA, which indicates that there will be fewer trade-creation benefits from AFTA and a greater likelihood of trade diversion once the AFTA scheme has been fully implemented. This similarity pattern explains the reasons for future collaboration among member countries and supportive arguments for the future extension of ASEAN ("ASEAN+". Market-penetration and development strategies should be employed by Thai exporters when accessing the ASEAN market.

  17. Carbon Dioxide Reduction Technology Trade Study

    Science.gov (United States)

    Jeng, Frank F.; Anderson, Molly S.; Abney, Morgan B.

    2011-01-01

    For long-term human missions, a closed-loop atmosphere revitalization system (ARS) is essential to minimize consumables. A carbon dioxide (CO2) reduction technology is used to reclaim oxygen (O2) from metabolic CO2 and is vital to reduce the delivery mass of metabolic O2. A key step in closing the loop for ARS will include a proper CO2 reduction subsystem that is reliable and with low equivalent system mass (ESM). Sabatier and Bosch CO2 reduction are two traditional CO2 reduction subsystems (CRS). Although a Sabatier CRS has been delivered to International Space Station (ISS) and is an important step toward closing the ISS ARS loop, it recovers only 50% of the available O2 in CO2. A Bosch CRS is able to reclaim all O2 in CO2. However, due to continuous carbon deposition on the catalyst surface, the penalties of replacing spent catalysts and reactors and crew time in a Bosch CRS are significant. Recently, technologies have been developed for recovering hydrogen (H2) from Sabatier-product methane (CH4). These include methane pyrolysis using a microwave plasma, catalytic thermal pyrolysis of CH4 and thermal pyrolysis of CH4. Further, development in Sabatier reactor designs based on microchannel and microlith technology could open up opportunities in reducing system mass and enhancing system control. Improvements in Bosch CRS conversion have also been reported. In addition, co-electrolysis of steam and CO2 is a new technology that integrates oxygen generation and CO2 reduction functions in a single system. A co-electrolysis unit followed by either a Sabatier or a carbon formation reactor based on Bosch chemistry could improve the overall competitiveness of an integrated O2 generation and CO2 reduction subsystem. This study evaluates all these CO2 reduction technologies, conducts water mass balances for required external supply of water for 1-, 5- and 10-yr missions, evaluates mass, volume, power, cooling and resupply requirements of various technologies.

    Institute of Scientific and Technical Information of China (English)

    LU MingXin; LAI XueJia; XIAO GuoZhen; QIN Lei

    2007-01-01

    DNA cryptography is a new field which has emerged with progress in the research of DNA computing. In our study, a symmetric-key cryptosystem was designed by applying a modern DNA biotechnology, microarray, into cryptographic technologies. This is referred to as DNA symmetric-key cryptosystem (DNASC). In DNASC,both encryption and decryption keys are formed by DNA probes, while its ciphertext is embedded in a specially designed DNA chip (microarray). The security of this system is mainly rooted in difficult biology processes and problems, rather than conventional computing technology, thus it is unaffected by changes from the attack of the coming quantum computer. The encryption process is a fabrication of a specially designed DNA chip and the decryption process is the DNA hybridization.In DNASC, billions of DNA probes are hybridized and identified at the same time,thus the decryption process is conducted in a massive, parallel way. The great potential in vast parallelism computation and the extraordinary information density of DNA are displayed in DNASC to some degree.

    Semin, Semih; Güldal, Dilek; Demiral, Yücel

    2007-05-01

    Medical technology trade is one of the most affected health areas by global regulations in the developing countries. The aim of the study is to examine recent changes in medical technology import and export and their results in Turkey. Data show that the total medical technology imports (MTI) increased from $ 34.6 million to $ 3427.9 million between 1970 and 2003. While MTI constituted 3.6% of total imports in 1970 and 1.3% in 1980, this ratio raised up to 4.9% in 2003. The ratio of MTI in total health expenditures were also increased from 7.6% in 1970 to 31.5% in 2003. Medical technology exports (MTE) have been increased from $ 0.9 million in 1970 to $ 303.2 million in 2003. The ratio of MTE to MTI increased from 2.7% to 13.9% between 1970 and 1990 and decreased after 1990, to 8.8%. Our study implied that the medical technology trade in Turkey has been negatively affected and in some respects differs from some other important industries in the globalization era. Nevertheless, detailed comparative studies in different developing countries such as China, Brazil, Mexico and India, are needed to explore the real state of medical technology trade, use and the effects of globalization on these topics.

  5. Export experience and key success factors in cross-border trade: Evidence from Southern Africa

    Directory of Open Access Journals (Sweden)

    Shepherd Dhliwayo

    2017-01-01

    Full Text Available Orientation: Cross-border trade (CBT is an important economic activity that contributes to the development of many economies of the developing world.Research purpose:  The two primary aims of the study were to find out the major factors needed to succeed in cross-border trading and whether the importance of these factors significantly decreased with export experience.Motivation for the study: The economic contribution of cross-border trade (CBT is often understated. As a result, it does not get the attention it deserves.Research design, approach and method: Data were collected in Gauteng from 146 cross-border traders from 10 Southern African Development Community (SADC countries. A cross-sectional research design was used.Main findings: The major key success factors were found to be skills/knowledge in; markets and supplies; financial management; and border issues. The importance of these factors was found to not significantly change with levels of export experience.Practical/managerial implications:  Stakeholders should know that small firms of differing export experience require the same interventions to succeed. Interventions should empower traders to better access markets and supplies, improve their financial management skills and ease border constraints.Contribution/value-add: Few studies on cross border trading have been carried out in the Southern African Development Community region. The key success factors and the constraints in this type of trade had not been adequately explored. The economic contribution of CBT, which usually goes unnoticed, was highlighted. Interventions to appropriately address the challenges faced, such as trading legitimacy and border harassment, were suggested.

    Matrosov, Evgenii S.; Huskova, Ivana; Kasprzyk, Joseph R.; Harou, Julien J.; Lambert, Chris; Reed, Patrick M.

    2015-12-01

    In this study, we link a water resource management simulator to multi-objective search to reveal the key trade-offs inherent in planning a real-world water resource system. We consider new supplies and demand management (conservation) options while seeking to elucidate the trade-offs between the best portfolios of schemes to satisfy projected water demands. Alternative system designs are evaluated using performance measures that minimize capital and operating costs and energy use while maximizing resilience, engineering and environmental metrics, subject to supply reliability constraints. Our analysis shows many-objective evolutionary optimization coupled with state-of-the art visual analytics can help planners discover more diverse water supply system designs and better understand their inherent trade-offs. The approach is used to explore future water supply options for the Thames water resource system (including London's water supply). New supply options include a new reservoir, water transfers, artificial recharge, wastewater reuse and brackish groundwater desalination. Demand management options include leakage reduction, compulsory metering and seasonal tariffs. The Thames system's Pareto approximate portfolios cluster into distinct groups of water supply options; for example implementing a pipe refurbishment program leads to higher capital costs but greater reliability. This study highlights that traditional least-cost reliability constrained design of water supply systems masks asset combinations whose benefits only become apparent when more planning objectives are considered.

  11. Summary of the structure and dynamics of international trade opportunities for new technologies

    Energy Technology Data Exchange (ETDEWEB)

    Watts, R.; Campbell, R.; Smith, S.; Sommers, P.

    1979-09-01

    This paper first provides a nomenclature and symbol system for describing the infrastructure that supports the export (or the import) of goods between countries. While the principal interest is in the export of high-technology goods to early foreign markets, the principles involved also apply to domestic commercialization of new technologies. The nomenclature-symbol system presented provides a schematic method of displaying complete relationships between actors and functions - an interaction matrix. A second aspect of the paper involves sketching out the need for further work to identify the motives, problems, and constraints of each key actor in international trade, particularly regarding new high-technology products. It is believed that the investigation should emphasize initial phases of market development when the behavior of actors does not appear to follow previous applications of microeconomic theory. Understanding this difference between theory and behavior could improve Federal efforts to commercialize new technologies. 18 references.

  3. An evaluation of the role played by remote sensing technology following the World Trade Center attack

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    Remote sensing technology has been widely recognized for contributing to emergency response efforts after the World Trade Center attack on September 11th, 2001. The need to coordinate activities in the midst of a dense, yet relatively small area, made the combination of imagery and mapped data strategically useful. This paper reviews the role played by aerial photography, satellite imagery, and LIDAR data at Ground Zero. It examines how emergency managers utilized these datasets, and identifies significant problems that were encountered. It goes on to explore additional ways in which imagery could have been used, while presenting recommendations for more effective use in future disasters and Homeland Security applications. To plan adequately for future events, it was important to capture knowledge from individuals who responded to the World Trade Center attack. In recognition, interviews with key emergency management and geographic information system (GIS) personnel provide the basis of this paper. Successful techniques should not be forgotten, or serious problems dismissed. Although widely used after September 11th, it is important to recognize that with better planning, remote sensing and GIS could have played an even greater role. Together with a data acquisition timeline, an expanded discussion of these issues is available in the MCEER/NSF report "Emergency Response in the Wake of the World Trade Center Attack: The Remote Sensing Perspective" (Huyck and Adams, 2002).

    Here, we present the engineering trade studies of a free-space optical communication system operating over a 30 km maritime channel for the months of January and July. The system under study follows the BB84 protocol with the following assumptions: a weak coherent source is used, Eve is performing the intercept resend attack and photon number splitting attack, prior knowledge of Eve's location is known, and Eve is allowed to know a small percentage of the final key. In this system, we examine the effect of changing several parameters in the following areas: the implementation of the BB84 protocol over the public channel, the technology in the receiver, and our assumptions about Eve. For each parameter, we examine how different values impact the secure key rate for a constant brightness. Additionally, we will optimize the brightness of the source for each parameter to study the improvement in the secure key rate.

    2010-05-30

    Current and potential future trends in technology, consumption and trade of food that may impact on food-borne disease are analysed and the key driving factors identified focusing on the European Union and, to a lesser extent, accounting for the United States and global issues. Understanding of factors is developed using system-based methods and their impact is discussed in relation to current events and predictions of future trends. These factors come from a wide range of spheres relevant to food and include political, economic, social, technological, regulatory and environmental drivers. The degree of certainty in assessing the impact of important driving factors is considered in relation to food-borne disease. The most important factors driving an increase in the burden of food-borne disease in the next few decades were found to be the anticipated doubling of the global demand for food and of the international trade in food next to a significantly increased consumption of certain high-value food commodities such as meat and poultry and fresh produce. A less important factor potentially increasing the food-borne disease burden would be the increased demand for convenience foods. Factors that may contribute to a reduction in the food-borne disease burden were identified as the ability of governments around the world to take effective regulatory measures as well as the development and use of new food safety technologies and detection methods. The most important factor in reducing the burden of food-borne disease was identified as our ability to first detect and investigate a food safety issue and then to develop effective control measures. Given the global scale of impact on food safety that current and potentially future trends have, either by potentially increasing or decreasing the food-borne disease burden, it is concluded that a key role is fulfilled by intergovernmental organisations and by international standard setting bodies in coordinating the

    Visual search has been a long-standing problem in applications such as location recognition and product search. Much research has been done on image representation, matching, indexing, and retrieval. Key component technologies for visual search have been developed, and numerous real-world applications are emerging. To ensure application interoperability, the Moving Picture Experts Group (MPEG) has begun standardizing visuaJ search technologies and is developing the compact descriptors for visua) search (CDVS) standard. MPEG seeks to develop a collaborative platform for evaluating existing visual search technologies. Peking University has participated in this standardization since the 94th MPEG meeting, and significant progress has been made with the various proposals. A test model (TM) has been selected to determine the basic pipeline and key components of visual search. However, the first-version TM has high computational complexity and imperfect retrieval and matching. Core experiments have therefore been set up to improve TM. In this article, we summarize key technologies for visual search and report the progress of MPEG CDVS. We discuss Peking University' s efforts in CDVS and also discuss unresolved issues.

    2011-05-01

    Full Text Available Abstract Background Over the past ten years the promotion of recovery has become a stated aim of mental health policies within a number of English speaking countries, including Scotland. Implementation of a recovery approach involves a significant reorientation of mental health services and practices, which often poses significant challenges for reformers. This article examines how four key technologies of recovery have assisted in the move towards the creation of a recovery-oriented mental health system in Scotland. Methods Drawing on documentary analysis and a series of interviews we examine the construction and implementation of four key recovery 'technologies' as they have been put to use in Scotland: recovery narratives, the Scottish Recovery Indicator (SRI, Wellness Recovery Action Planning (WRAP and peer support. Results Our findings illuminate how each of these technologies works to instantiate, exemplify and disseminate a 'recovery orientation' at different sites within the mental health system in order to bring about a 'recovery oriented' mental health system. They also enable us to identify some of the factors that facilitate or hinder the effectiveness of those technologies in bringing about a change in how mental health services are delivered in Scotland. These finding provide a basis for some general reflections on the utility of 'recovery technologies' to implement a shift towards recovery in mental health services in Scotland and elsewhere. Conclusions Our analysis of this process within the Scottish context will be valuable for policy makers and service coordinators wishing to implement recovery values within their own national mental health systems.

  19. Smart Order Routing Technology in the New European Equity Trading Landscape

    Science.gov (United States)

    Ende, Bartholomäus; Gomber, Peter; Lutat, Marco

    In Europe, fragmentation of execution venues has been triggered by increasing competition among markets and a new regulatory environment set up by MiFID. Against this background, IT-based sophisticated order routing systems (Smart Order Routing systems) promise to assure efficiency despite fragmented markets. This raises the question on the relevance and economic value of this technology in European equity trading. Based on order book data for EURO STOXX 50 securities of ten European electronic execution venues, this paper assesses the potential of Smart Order Routing technology by measuring the performance of actual executions in European order book trading relative to a Smart Order Router implementation that detects and accesses best European prices. We identify 6.71% full trade troughs and 6.45% partial trade-throughs in our dataset enabling for significant absolute and relative savings. This indicates that Smart Order Routing technology can provide business value by improving order executions in European cross-tradable equities.

  20. Knowledge Management and Technology in Shahid Rajaei Trading Port

    Directory of Open Access Journals (Sweden)

    2012-11-01

    Full Text Available For most organizations, knowledge management is a process which aims at replacing conventional business processes. The dilemma is that for most of them, these processes that KM aims at computerizing do not exist. What many fail to comprehend is that knowledge management is more of a business practice than a product. The aim of this study is to examine the place of people and technology in the context of knowledge management. Based on the emerging concept of intellectual capitals where knowledge is perceived as part of the property of a firm, this study will seek to foster an understanding of knowledge management and determine the validity of the notion that knowledge management can replace human intellectuals in organizations. In conducting the study, a qualitative approach was adopted. Data was obtained from both secondary and primary sources. The primary data collection process was undertaken at Rajaei port which is based in the Islamic republic of Iran. The results were subsequently analyzed. For purposes of standardizing the results to make them suitable for comparison, the average auto sum formula was adopted. The results revealed a consistency with much of the literature on the subject to the effect that human resources are the key success factors in the implementation of knowledge management. Knowledge management is not a process for replacing human labour; on the contrary it is dependent on the knowledge residing in people minds. Recommendations were made that Rajaei port managers should begin by creating suitable environments for people to share their tacit knowledge. Further, that they should encourage a knowledge sharing culture in their organization as sustainable knowledge management is more dependent on the ability of employees to share each other’s knowledge than on complex technology.

    Many active magnetic shielding designs have been proposed in order to reduce the radiation exposure received by astronauts on long duration, deep space missions. While these designs are promising, they pose significant engineering challenges. This work presents a survey of the major systems required for such unconfined magnetic field design, allowing the identification of key technologies for future development. Basic mass calculations are developed for each system and are used to determine the resulting galactic cosmic radiation exposure for a generic solenoid design, using a range of magnetic field strength and thickness values, allowing some of the basic characteristics of such a design to be observed. This study focuses on a solenoid shaped, active magnetic shield design; however, many of the principles discussed are applicable regardless of the exact design configuration, particularly the key technologies cited.

    Full Text Available Trade relations between Latin America and the Republic of Korea started in the early sixties, but only after the beginning of the new century have become more dynamic, especially for the Asian nation. Behind the Korean export boom is the governmental thrust to science and technology, which has resulted in the production of goods with higher added value. The pattern of trade specialization followed by South Korea has allowed it to become one of the leading exporting nations of high technology goods in the world. On the other hand, Latin American nations have also enjoyed a remarkable growth in exports in the last decade, although their exporting profile contrast with that of Korea because their exports tend to be mainly primary products with low added value and some semi-finished goods . The pattern of specialization in Latin America is explained by its provision of vast natural resources, giving it a comparative advantage in world commodity markets. Unfortunately these advantages have not translated into sustained industrial developments throughout the region. In this context, the purpose of this paper is to illustrate the trade trends between South Korea and Latin America in the last ten years in an attempt to understand the reasons behind the asymmetries in trade flows that have been set in this period. The underlying assumption is that the commercial relationship between both parties depends on the pattern of specialization emerged in recent times and responds to the institutional policies implemented by both South Korea and by Latin American nations. The case of Mexico is highlighted because it is getting historic deficits with the Asian nation.

  10. Commercialization of LARC (TradeMark) -SI Polyimide Technology

    Science.gov (United States)

    Bryant, Robert G.

    2011-01-01

    LARC(TradeMark)-SI, Langley Research Center- Soluble Imide, was developed in 1992, with the first patent issuing in 1997, and then subsequent patents issued in 1998 and 2000. Currently, this polymer has been successfully licensed by NASA, and has generated revenues, at the time of this reporting, in excess of $1.4 million. The success of this particular polymer has been due to many factors and many lessons learned to the point that the invention, while important, is the least significant part in the commercialization of this material. Commercial LARC(TradeMark)-SI is a polyimide composed of two molar equivalents of dianhydrides: 4,4 -oxydiphthalic anhydride (ODPA), and 3,3 ,4,4 -biphenyltetracarboxylic dianhydride (BPDA) and 3,4 -oxydianiline (3,4 -ODA) as the diamine. The unique feature of this aromatic polyimide is that it remains soluble after solution imidization in high-boiling, polar aprotic solvents, even at solids contents of 50-percent by weight. However, once isolated and heated above its T(sub g) of 240 C, it becomes insoluble and exhibits high-temperature thermoplastic melt-flow behavior. With these unique structure property characteristics, it was thought this would be an advantage to have an aromatic polyimide that is both solution and melt processable in the imide form. This could potentially lead to lower cost production as it was not as equipment- or labor-intensive as other high-performance polyimide materials that either precipitate or are intractable. This unique combination of properties allowed patents with broad claim coverage and potential commercialization. After the U.S. Patent applications were filed, a Small Business Innovation Research (SBIR) contract was awarded to Imtec, Inc. to develop and supply the polyimide to NASA and the general public. Some examples of demonstration parts made with LARC(TradeMark)-SI ranged from aircraft wire and multilayer printed-circuit boards, to gears, composite panels, supported adhesive tape, composite

    Full Text Available The marine aquarium hobby is a global industry with trade chains on six continents. This industry is undergoing rapid changes in hobbyistpreferences that are in part driven by global economies and technology. In an effort to better assess the past trends and help provide insightinto future growth and demand, we assessed three different trade data sources, the United States-State of Florida Marine Life Landings, CITESstony coral imports, and United States Fish and Wildlife Service’s Law Enforcement Information Systems import data for ‘live rock’. Data forthe past 10 years were analyzed and a clear trend of growth followed by decline was observed with the peak and degree of decline varying forthe different trade categories. While the global economic downturn decreased trade volumes across the board other forces have dramatically affectedthe importation of coral reef products. ‘Live Rock’ and Florida produced ‘live sand’ dramatically decreased two years prior to the globaleconomic recession. The decline of these trade categories coincides with rapid changes in technology used to maintain captive reef aquariumswhich allowed for the advent of the smaller “nano” reef tanks. Importing and exporting countries, CITES and other international governmentbodies, concerned Non-Governmental Organizations and scientist would greatly benefit from a deeper understanding of this industry from aproducer and consumer standpoint in order to better predict how the marine aquarium hobby will be shaped by external forces in the future.

  8. Key factors affecting the deployment of electricity generation technologies in energy technology scenarios

    Energy Technology Data Exchange (ETDEWEB)

    Ruoss, F.; Turton, H.; Hirschberg, S.

    2009-12-15

    This report presents the findings of a survey of key factors affecting the deployment of electricity generation technologies in selected energy scenarios. The assumptions and results of scenarios, and the different models used in their construction, are compared. Particular attention is given to technology assumptions, such as investment cost or capacity factors, and their impact on technology deployment. We conclude that the deployment of available technologies, i.e. their market shares, can only be explained from a holistic perspective, and that there are strong interactions between driving forces and competing technology options within a certain scenario. Already the design of a scenario analysis has important impacts on the deployment of technologies: the choice of the set of available technologies, the modeling approach and the definition of the storylines determine the outcome. Furthermore, the quantification of these storylines into input parameters and cost assumptions drives technology deployment, even though differences across the scenarios in cost assumptions are not observed to account for many of the observed differences in electricity technology deployment. The deployment can only be understood after a consideration of the interplay of technology options and the scale of technology deployment, which is determined by economic growth, end-use efficiency, and electrification. Some input parameters are of particular importance for certain technologies: CO{sub 2} prices, fuel prices and the availability of carbon capture and storage appear to be crucial for the deployment of fossil-fueled power plants; maximum construction rates and safety concerns determine the market share of nuclear power; the availability of suitable sites represents the most important factor for electricity generation from hydro and wind power plants; and technology breakthroughs are needed for solar photovoltaics to become cost-competitive. Finally, this analysis concludes with a

    Meguro, Akira; Harada, Satoshi; Watanabe, Mitsunobu

    2003-12-01

    Nippon Telephone and Telegram Corporation (NTT) continues to develop the modular mesh-type deployable antenna. Antenna diameter can be changed from 5 m to about 20 m by changing the number of modules used with surface accuracy better than 2.4 mm RMS (including all error factors) with sufficient deployment reliability. Key technologies are the antenna's structural design, the deployment mechanism, the design tool, the analysis tool, and modularized testing/evaluation methods. This paper describes our beam steering mechanism. Tests show that it yields a beam pointing accuracy of better than 0.1°. Based on the S-band modular mesh antenna reflector, the surface accuracy degradation factors that must be considered in designing the new antenna are partially identified. The influence of modular connection errors on surface accuracy is quantitatively estimated. Our analysis tool SPADE is extended to include the addition of joint gaps. The addition of gaps allows non-linear vibration characteristics due to gapping in deployment hinges to be calculated. We intend to design a new type of mesh antenna reflector. Our new goal is an antenna for Ku or Ka band satellite communication. For this mission, the surface shape must be 5 times more accurate than is required for an S-band antenna.

    In view of the significant difficulties of propagation, planting and simple product in Dendrobium catenatum(D. officinale)industry development, a series of research were carried out. Genome study showed that D. catenatum is a specie of diploid with 38 chromosomes and 28 910 protein-coding genes. It was identified that specific genes accumulated in different organs at the transcriptome level. We got an insight into the gene regulation mechanism of the loss of the endospermous seed, the wide ecological adaptability and the synthesis of polysaccharides, which provided a theoretical basis for genetic engineering breeding and development and utilization of active pharmaceutical ingredients. The rapid propagation system was established for applying to industrialized production by overcoming breeding problems on seed setting and sprouting, which laid a foundation for artificial cultivation of D. catenatum. And in order to give a clear explanation of genetic variation of important economic traits, we built up the breeding system. Since special varieties of D. catenatum were bred, it helped solve the problem of trait segregation of seedling progeny and support the improvement of D. catenatum industry.

    Full Text Available E-commerce on the internet has the ability to produce millions of transactions and a great number of merchants whose supply merchandise over the internet. As a result, it is difficult for entities to roam over every site on the internet and choose the best merchandise to trade. So, in this paper we introduced a mobile trade agent that visit the sites to gather and evaluate the information from merchant servers and decide to trade goods on behalf of the user. We observed that the combination of public key cryptosystem with distributed object technology make this proposed scheme more secure and efficient than the already existed schemes.

  16. How Do Trading Firms Upgrade Skills and Technology: A Theoretical Model

    Directory of Open Access Journals (Sweden)

    Mojca Lindic

    2015-12-01

    Full Text Available This paper studies the mechanisms of skill upgrading in trading firms by developing a theoretical model that relates the individual’s incentives for acquiring higher skills to the profit-maximizing behaviour of trading firms. The model shows that only the high ability individuals have incentives for acquiring higher skills, as long as they are compensated with higher wages after entering employment. Furthermore, high-productive firms have incentives for investing in higher technology, to employ high-skilled labour, and to engage in international trade. The decisions for technology dress-up and skill upgrading coincide with firm’s decisions to start importing and exporting as the latter requires higher technology and high-skilled labour. Contributions of the paper are twofold: gaining new insights by combining fragments of models on individual’s and firm’s behaviours, and broadening the content of the Melitz (2003 model by introducing importers and controlling for skilled and unskilled labour.

  17. Determinants of technology adoption in the retail trade industry – the case of SMEs in Spain

    Directory of Open Access Journals (Sweden)

    2015-05-01

    Full Text Available This paper analyzes the determinants of small and medium-sized enterprises’ technology adoption in the retail trade industry. From the theoretical perspective, two types of influential factors are differentiated in this respect: the personal characteristics of the manager/business owner and the business’s organizational characteristics. The empirical analysis is based on a survey of 268 small and medium-sized enterprises in the Spanish retail trade sector. A logistic regression specification is used as an econometric method. The results indicate that both the acquisition of new technical and electronic equipment and the obtaining of new software are affected by the two types of determinants previously pointed out. The manager/business owner’s entrepreneurial motivation and educational background have significant influences on technology adoption in this type of companies. Furthermore, being part of a business group, carrying out training activities for the employees and inter-firm cooperation also positively influence technology adoption in the retail trade industry.

    This article assesses the impact of technological changes on women's employment in Bangladesh and Sri Lanka. The findings of the research initiated by UN University Institute for New Technologies were used to determine how globalization and technological change alter women's role in the society and the economy in two comparable yet contrasting economies. In Bangladesh and Sri Lanka, the manufacturing and service sectors have grown as a result of the globalization strategies of the two governments. The use of new technologies in work processes has been a function of the countries' participation in global trade, and high levels of foreign direct investment have been the source of much job creation. In both countries, a large proportion of the new industrial workforce consists of women. However, while creating new employment opportunities and improving pay and conditions for some women, jobs tend to be based on flexible, short-term forms of employment with serious health and safety risks. Furthermore, technological advancement like automation increases the number of unemployed "unskilled" workers. Lastly, these two countries seem unaware of the implications of new technology, which makes them vulnerable and weak participants in the global market. Therefore, awareness can be enhanced by a greater exposure to technology through work experience and good quality training.

    This article introduces the fabrication technology processes of the capacitive pressure sensor based on the low temperature co-fired ceramic (LTCC) material. Filling the cavity with different materials as a sacrificial layer is mainly discussed, and two different materials are chosen in the fabrication. It is found that the cavity filled with polyimide expands largely during sintering, while carbon ESL49000 material filled is more preferable to keep the cavity flat. Finally, the structure leaving without an air evacuation channel is designed and tested in a built-up pressure environment, the frequency measured decreases approximately linearly with the pressure applied, which proves the design leaving no air evacuation channel advisable.

    2011-12-01

    The world population will continue to face biological threats, whether they are naturally occurring or intentional events. The speed with which diseases can emerge and spread presents serious challenges, because the impact on public health, the economy, and development can be huge. The U.S. government recognizes that global public health can also have an impact on national security. This global perspective manifests itself in U.S. policy documents that clearly articulate the importance of biosurveillance in providing early warning, detection, and situational awareness of infectious disease threats in order to mount a rapid response and save lives. In this commentary, we suggest that early recognition of infectious disease threats, whether naturally occurring or man-made, requires a globally distributed array of interoperable hardware and software fielded in sufficient numbers to create a network of linked collection nodes. We argue that achievement of this end state will require a degree of cooperation that does not exist at this time-either across the U.S. federal government or among our global partners. Successful fielding of a family of interoperable technologies will require interagency research, development, and purchase ("acquisition") of biosurveillance systems through cooperative ventures that likely will involve our strategic allies and public-private partnerships. To this end, we propose leveraging an existing federal interagency group to integrate the acquisition of technologies to enable global biosurveillance.

    Girault, J. PH.

    1992-01-01

    For several years, active magnetic bearings (AMB) have demonstrated their capabilities in many fields, from industrial compressors to control wheel suspension for spacecraft. Despite this broad area, no significant advance has been observed in rocket propulsion turbomachinery, where size, efficiency, and cost are crucial design criteria. To this respect, Societe Europeenne de Propulsion (SEP) had funded for several years significant efforts to delineate the advantages and drawbacks of AMB applied to rocket propulsion systems. Objectives of this work, relative technological basis, and improvements are described and illustrated by advanced turbopump layouts. Profiting from the advantages of compact design in cryogenic environments, the designs show considerable improvements in engine life, performances, and reliability. However, these conclusions should still be tempered by high recurrent costs, mainly due to the space-rated electronics. Development work focused on this point and evolution of electronics show the possibility to decrease production costs by an order of magnitude.

    Little is known about the prevalence and risk factors associated with sex trading among HIV-positive women. A total of 242 HIV-positive women were recruited in five regions in Kazakhstan. These women completed a survey containing items on socio-demographics, HIV stigma, intimate partner violence, and partner risk behaviors. Multivariate regression was used to examine associations between risk factors and sex trading after controlling for socio-demographic factors. Fifty-six (23.1%) women reported trading sex in the past 90 days. Women who reported recent sex trading were more likely than women who did not trade sex in the past 90 days to experience intimate partner violence (adjusted odds ratio [AOR]: 2.25; 95% confidence interval [CI]: 1.08-4.73), to have been homeless in the past 90 days (AOR: 4.12; 95% CI: 1.19-14.29), and to know or suspect a male partner had a sexually transmitted infection (AOR: 2.20; 95% CI: 1.07-4.53), had sex with another partner (AOR: 4.53; 95% CI: 2.25-9.14), or injected drugs in the past year (AOR: 3.31; 95% CI: 1.64-6.65). These findings underscore the need for comprehensive HIV prevention and intervention programs that address the multi-level risk factors associated with sex trading for women infected with HIV.

  3. Radioisotope Power: A Key Technology for Deep Space Explorations

    Science.gov (United States)

    Schmidt, George R.; Sutliff, Thomas J.; Duddzinski, Leonard

    2009-01-01

    A Radioisotope Power System (RPS) generates power by converting the heat released from the nuclear decay of radioactive isotopes, such as Plutonium-238 (Pu-238), into electricity. First used in space by the U.S. in 1961, these devices have enabled some of the most challenging and exciting space missions in history, including the Pioneer and Voyager probes to the outer solar system; the Apollo lunar surface experiments; the Viking landers; the Ulysses polar orbital mission about the Sun; the Galileo mission to Jupiter; the Cassini mission orbiting Saturn; and the recently launched New Horizons mission to Pluto. Radioisotopes have also served as a versatile heat source for moderating equipment thermal environments on these and many other missions, including the Mars exploration rovers, Spirit and Opportunity. The key advantage of RPS is its ability to operate continuously, independent of orientation and distance relative to the Sun. Radioisotope systems are long-lived, rugged, compact, highly reliable, and relatively insensitive to radiation and other environmental effects. As such, they are ideally suited for missions involving long-lived, autonomous operations in the extreme conditions of space and other planetary bodies. This paper reviews the history of RPS for the U.S. space program. It also describes current development of a new Stirling cycle-based generator that will greatly expand the application of nuclear-powered missions in the future.

    1998-03-01

    The potential exists for peaceful and constructive bilateral relations between India and Pakistan. Domestic developments in both countries, the changing global economic and political environment, and structural changes in regional trading patterns have created new opportunities for replacing traditional Indian and Pakistani perceptions of hostility and suspicion with mutual understanding and trust. This substitution process can be accelerated by increasing people-to-people contact, the free flow of information, and economic and technological cooperation between the two neighbors. Nonmilitary confidence building measures could create conditions for an incremental reduction on tensions between India and Pakistan. A popular consciousness for enhanced bilateral cooperation is growing. This process could be strengthened by identifying and exploring new areas of mutually beneficial cooperation that could pave the way for peace.

  9. Cap-and-trade policy: The influence on investments in carbon dioxide reducing technologies in Indiana

    Science.gov (United States)

    Fahie, Monique

    With most of the energy produced in the state of Indiana coming from coal, the implementation of policy instruments such as cap-and-trade, which is included in the most recent climate bill, will have significant effects. This thesis provides an analysis of the effects that a cap-and-trade policy might have on the investment decisions for alternative technologies in the power plant sector in Indiana. Two economic models of representative coal-fired power plants, Gallagher (600MW) and Rockport (2600MW), are selected and used to evaluate the repowering decision of a plant for several technologies: integrated gasification combined cycle (IGCC), wind farm combined with natural gas combined cycle (NGCC) and supercritical pulverized coal (SCPC). The firm will make its decisions based on the net present value (NPV) of cost estimates for these CO2 reducing technologies, the cost of purchasing offsets and CO 2 allowances. This model is applied to a base case and three American Clean Energy and Security Act of 2009 cases derived from the Energy Information Administration (EIA, 2009b). A sensitivity analysis is done on the discount rate and capital costs. The results of the study indicate that a SCPC plant without carbon capture and storage (CCS) is the least costly compliance option for both plants under all of the cases while retrofitting the existing plant with CCS is the most expensive. Gallagher's three least expensive options across most scenarios were SCPC without CCS, the operation of the existing plant as is and investment in wind plus NGCC. Rockport's three least expensive compliance options across most scenarios were SCPC without CCS, the operation of the existing plant as is and IGCC without CCS. For both plants, when a 12% discount rate is utilized, NPV of costs are generally lower and the operation of the existing plant technology with the aid of allowances and offsets to be in compliance is the cheapest option. If capital costs were to decrease by 30%, a SCPC

    Full Text Available Abstract Background Health Technology Reassessment (HTR is a structured, evidence-based assessment of the clinical, social, ethical and economic effects of a technology currently used in the health care system, to inform optimal use of that technology in comparison to its alternatives. Little is known about current international HTR practices. The objective of this research was to summarize experience-based information gathered from international experts on the development, initiation and implementation of a HTR program. Methods A mixed methods approach, using a survey and in-depth interviews, was adopted. The survey covered 8 concepts: prioritization/identification of potentially obsolete technologies; program development; implementation; mitigation; program championing; stakeholder engagement; monitoring; and reinvestment. Members of Health Technology Assessment International (HTAi and the International Network of Agencies for Health Technology Assessment (INAHTA formed the sampling frame. Participation was solicited via email and the survey was administered online using SurveyMonkey. Survey results were analyzed using descriptive statistics. To gather more in-depth knowledge, semi-structured interviews were conducted among organizations with active HTR programs. Interview questions were developed using the same 8 concepts. The hour-long interviews were recorded, transcribed and analyzed using constant comparative analysis. Results Ninety-five individuals responded to the survey: 49 were not discussing HTR, 21 were beginning to discuss HTR, nine were imminently developing a program, and 16 participants had programs and were completing reassessments. The survey results revealed that methods vary widely and that although HTR is a powerful tool, it is currently not being used to its full potential. Of the 16 with active programs, nine agreed to participate in follow-up interviews. Interview participants identified early and extensive stakeholder

Commentators often point to new medical technology as the key driver for burgeoning expenditures. This paper critically appraises this conjecture, based on an analysis of the existing literature, with the aim of offering a more detailed and considered analysis of this relationship. Several databases were searched to identify relevant literature. Various categories of studies (eg, multivariate and cost-effectiveness analyses were included to cover different perspectives, methodological approaches, and issues regarding the link between medical technology and costs. Selected articles were reviewed and relevant information was extracted into a standardized template and analyzed for key cross-cutting themes, ie, impact of technology on costs, factors influencing this relationship, and methodological challenges in measuring such linkages. A total of 86 studies were reviewed. The analysis suggests that the relationship between medical technology and spending is complex and often conflicting. Findings were frequently contingent on varying factors, such as the availability of other interventions, patient population, and the methodological approach employed. Moreover, the impact of technology on costs differed across technologies, in that some (eg, cancer drugs, invasive medical devices had significant financial implications, while others were cost-neutral or cost-saving. In light of these issues, we argue that decision-makers and other commentators should extend their focus beyond costs solely to include consideration of whether medical technology results in

    The Amazon region is globally connected through agricultural exports, with the Brazilian state of Mato Grosso in particular emerging as a key node in the global virtual water trade network in recent years, based largely on rainfed agriculture. The anticipated growth in the world's population suggests that virtual water trade will only become more important to global food security. In this presentation we will evaluate strategies for improving the resilience of rainfed agriculture in the region, particularly for the nearly 12 million hectares of sandy soil with low water holding capacity within Mato Grosso that has largely been converted to agricultural use. We will review land use change trajectories and present results from soil water balance modeling and carbon fluxes for a range of future scenarios, including continued agricultural extensification, potential strategies for agricultural intensification, and novel water and carbon management strategies including biochar use in sandy soils to improve soil water holding capacities and soil carbon sequestration. We will also consider the role that irrigation might play in the future in the Amazon for improving agricultural resilience to climate change and feedbacks between irrigation and land use change pressures, noting that groundwater resources in the region are presently among the least exploited on the planet.

    Pavone, Vincenzo; Esposti, Sara Degli

    2012-07-01

    As surveillance-oriented security technologies (SOSTs) are considered security enhancing but also privacy infringing, citizens are expected to trade part of their privacy for higher security. Drawing from the PRISE project, this study casts some light on how citizens actually assess SOSTs through a combined analysis of focus groups and survey data. First, the outcomes suggest that people did not assess SOSTs in abstract terms but in relation to the specific institutional and social context of implementation. Second, from this embedded viewpoint, citizens either expressed concern about government's surveillance intentions and considered SOSTs mainly as privacy infringing, or trusted political institutions and believed that SOSTs effectively enhanced their security. None of them, however, seemed to trade privacy for security because concerned citizens saw their privacy being infringed without having their security enhanced, whilst trusting citizens saw their security being increased without their privacy being affected.

    The state-of-the-art of hydrogen storage technology is reviewed, including gaseous, liquid, hydride, surface adsorbed media, glass microsphere, chemical reaction, and liquid chemical technologies. The review of each technology includes a discussion of advantages, disadvantages, likelihood of success, and key research and development activities. A preferred technological path for the development of effective near-term hydrogen storage includes both cur-rent DOT qualified and advanced compressed storage for down-sized highly efficient but moderate range vehicles, and liquid storage for fleet vehicle applications. Adsorbate media are also suitable for fleet applications but not for intermittent uses. Volume-optimized transition metal hydride beds are also viable for short range applications. Long-term development of coated nanoparticulate or metal matrix high conductivity magnesium alloy, is recommended. In addition, a room temperature adsorbate medium should be developed to avoid cryogenic storage requirements. Chemical storage and oxidative schemes present serious obstacles which must be addressed for these technologies to have a future role.

Mechanism performances are analyzed in terms of the first and the second order influence coefficient matrix firstly. So the sizes of mechanism, which are better for all the performance indices of both kinematics and dynamics, can be confirmed and the restriction due to considering only the first order influence coefficient matrix in the past is broken through. Therefore, the theory basis for designing the mechanism size of novel engraving machine with better performances is provided. In addition, method for tool path planning and control technology for engraving force is also studied in the paper. The proposed algorithm for tool path planning on curved surface can be applied to arbitrary spacial curved surface in theory, control technology for engraving force based on fuzzy neural network(FNN has well adaptability to the changing environment. Research on teleoperation for parallel engraving machine based on B/S architecture resolves the key problems such as control mode, sharing mechanism for multiuser, real-time control for engraving job and real-time transmission for video information.

    We present the key technologies and capabilities that will enable a future, large-aperture ultravioletopticalinfrared (UVOIR) space observatory. These include starlight suppression systems, vibration isolation and control systems, lightweight mirror segments, detector systems, and mirror coatings. These capabilities will provide major advances over current and near-future observatories for sensitivity, angular resolution, and starlight suppression. The goals adopted in our study for the starlight suppression system are 10-10 contrast with an inner working angle of 20 milliarcsec and broad bandpass. We estimate that a vibration and isolation control system that achieves a total system vibration isolation of 140 dB for a vibration-isolated mass of 5000 kg is required to achieve the high wavefront error stability needed for exoplanet coronagraphy. Technology challenges for lightweight mirror segments include diffraction-limited optical quality and high wavefront error stability as well as low cost, low mass, and rapid fabrication. Key challenges for the detector systems include visible-blind, high quantum efficiency UV arrays, photon counting visible and NIR arrays for coronagraphic spectroscopy and starlight wavefront sensing and control, and detectors with deep full wells with low persistence and radiation tolerance to enable transit imaging and spectroscopy at all wavelengths. Finally, mirror coatings with high reflectivity ( 90), high uniformity ( 1) and low polarization ( 1) that are scalable to large diameter mirror substrates will be essential for ensuring that both high throughput UV observations and high contrast observations can be performed by the same observatory.

    Full Text Available Given the significant requirements for transforming and promoting the process industry, we present the major limitations of current petrochemical enterprises, including limitations in decision-making, production operation, efficiency and security, information integration, and so forth. To promote a vision of the process industry with efficient, green, and smart production, modern information technology should be utilized throughout the entire optimization process for production, management, and marketing. To focus on smart equipment in manufacturing processes, as well as on the adaptive intelligent optimization of the manufacturing process, operating mode, and supply chain management, we put forward several key scientific problems in engineering in a demand-driven and application-oriented manner, namely: ① intelligent sensing and integration of all process information, including production and management information; ② collaborative decision-making in the supply chain, industry chain, and value chain, driven by knowledge; ③ cooperative control and optimization of plant-wide production processes via human-cyber-physical interaction; and ④ life-cycle assessments for safety and environmental footprint monitoring, in addition to tracing analysis and risk control. In order to solve these limitations and core scientific problems, we further present fundamental theories and key technologies for smart and optimal manufacturing in the process industry. Although this paper discusses the process industry in China, the conclusions in this paper can be extended to the process industry around the world.

    Full Text Available This study examines fuel switching in electricity production following the introduction of the European Union’s Emissions Trading System (EU ETS for greenhouse gas emissions. A short-run restricted cost equation is estimated with carbon permits, high-carbon fuels, and low carbon fuels as variable inputs. Shadow values and substitution elasticities for carbon-free energy resources from nuclear, hydroelectric and renewable sources are imputed from the cost equation. The empirical analysis examines 12 European countries using monthly data on fuel use, prices, and electricity generation during the first phase of the European Emissions Trading System. Despite low emission permit prices, this study finds statistically significant substitution between fossil fuels and carbon free sources of energy for electric power production. Significant substitution between fossil fuels and nuclear energy also was found. Still, while 18 of the 20 substitution elasticities are statistically significant, they are all less than unity, consistent with limited substitution. Overall, these results suggest that prices for carbon emission permits relative to prices for carbon and carbon free sources of energy do matter but that electric power producers have limited operational flexibility in the short-run to satisfy greenhouse gas emission limits.

    The results of a study on the key technology of using shell sand, a kind of sea sand, as backfill for sea reclamation are described briefly. Laboratory tests show that the physical and mechanical properties of shell sand are as good as normal quartz sand. Based on the chemical test and durability test of shell sand it could be concluded that the influence of corrosion of shell sand by acid rain and sea water might be ignored in the evaluation of the safety and durability of the engineering project. The results of field improvement tests show that the bearing capacity of shell sand backfill foundation is more than 200 kPa after vibroflotation improvement or dynamic compaction improvement. The shell sand is a good backfill material for sea reclamation.

    The advance of the Internet and new technologies over the last decade has transformed the retailing panorama. More and more channels are emerging, causing consumers to change their habits and shopping behavior. An omnichannel strategy is a form of retailing that, by enabling real interaction, allows customers to shop across channels anywhere and at any time, thereby providing them with a unique, complete, and seamless shopping experience that breaks down the barriers between channels. This paper aims to identify the factors that influence omnichannel consumers' behavior through their acceptance of and intention to use new technologies during the shopping process. To this end, an original model was developed to explain omnichannel shopping behavior based on the variables used in the UTAUT2 model and two additional factors: personal innovativeness and perceived security. The model was tested with a sample of 628 Spanish customers of the store Zara who had used at least two channels during their most recent shopping journey. The results indicate that the key determinants of purchase intention in an omnichannel context are, in order of importance: personal innovativeness, effort expectancy, and performance expectancy. The theoretical and managerial implications are discussed. PMID:27516749

    Full Text Available The concept of Future Networks is based on the premise that current infrastructures require enhanced control, service customization, self-organization and self-management capabilities to meet the new needs in a connected society, especially of mobile users. In order to provide a high-performance mobile system, three main fields must be improved: radio, network, and operation and management. In particular, operation and management capabilities are intended to enable business agility and operational sustainability, where the addition of new services does not imply an excessive increase in capital or operational expenditures. In this context, a set of key-enabled technologies have emerged in order to aid in this field. Concepts such as Software Defined Network (SDN, Network Function Virtualization (NFV and Self-Organized Networks (SON are pushing traditional systems towards the next 5G network generation.This paper presents an overview of the current status of these promising technologies and ongoing works to fulfill the operational and management requirements of mobile infrastructures. This work also details the use cases and the challenges, taking into account not only SDN, NFV, cloud computing and SON but also other paradigms.

    In recent years, the increasing development of cloud computing technologies laid critical foundation for efficiently solving complicated geographic issues. However, it is still difficult to realize the cooperative operation of massive heterogeneous geographical models. Traditional cloud architecture is apt to provide centralized solution to end users, while all the required resources are often offered by large enterprises or special agencies. Thus, it's a closed framework from the perspective of resource utilization. Solving comprehensive geographic issues requires integrating multifarious heterogeneous geographical models and data. In this case, an open computing platform is in need, with which the model owners can package and deploy their models into cloud conveniently, while model users can search, access and utilize those models with cloud facility. Based on this concept, the open cloud service strategies for the sharing of heterogeneous geographic analysis models is studied in this article. The key technology: unified cloud interface strategy, sharing platform based on cloud service, and computing platform based on cloud service are discussed in detail, and related experiments are conducted for further verification.

While fast communications can be realized using laser communications in fiber and free-space, inherently secure communications can be achieved using quantum key distribution (QKD). By combining both technologies in a single device, many synergies can be exploited, therefore reducing size, weight and power of future systems. In recent experiments we demonstrated quantum communications over large distances as well as between an aircraft and a ground station which proved the feasibility of QKD between moving partners. Satellites thus may be used as trusted nodes in combination with QKD receiver stations on ground, thereby enabling fast and secure communications on a global scale. We discuss the previous experiment with emphasis on necessary developments to be done and corresponding ongoing research work of German Aerospace Center (DLR) and Ludwig Maximilians University Munich (LMU). DLR is performing research on satellite and ground terminals for the high-rate laser communication component, which are enabling technologies for the QKD link. We describe the concept and hardware of three generations of OSIRIS (Optical High Speed Infrared Link System) laser communication terminals for low Earth orbiting satellites. The first type applies laser beam pointing solely based on classical satellite control, the second uses an optical feedback to the satellite bus and the third, currently being in design phase, comprises of a special coarse pointing assembly to control beam direction independent of satellite orientation. Ongoing work also targets optical terminals for CubeSats. A further increase of beam pointing accuracy can be achieved with a fine pointing assembly. Two ground stations will be available for future testing, an advanced stationary ground station and a transportable ground station. In parallel the LMU QKD source size will be reduced by more than an

    2006-06-01

    Full Text Available This study tries to quantify the technology level of products based on the concept of product ladder. While many studies on country technology competitiveness use the aggregate indices such as total factor productivity and revealed comparative advantage, this study estimates the ranking of about 2000 products in product ladder by using SITC 5 digit level export data. Based on the product ladder, this study measures the country and industry ranking and explores the characteristics of the ranking. It provides the international comparison of inter-industry and intra-industry ranking differences in product ladder. The statistical relationships between the ranking in product ladder and the determinants of technology level such as R&D and physical capital investment and wage, confirms that the measured ranking in product ladder could be regarded as an indirect indicator of technology level. The product ladder is applied to the estimation of production function to see the effect of the product differentiation on labor productivity.

    2015-12-01

    Full Text Available The present study investigated the inventory model for a retailer under two levels of trade credit to reflect the supply chain management. Supplier offers trade credit period of M to the retailer while in turn retailer provides a trade credit period of N to his/her customers. The supplier is willing to provide the retailer a full trade credit period for payments and the retailer offers the partial trade credit period to his/her customers. Here, selling items are considered as perishable items such as fruits, fresh fishes, gasoline, photographic films, etc. so that its potential worth decreases. It is assumed that decay in potential worth of items can be increased by using preservation technology. The demand is considered as the function of selling price and trade credit. Ordering cost can be reducing due to learning by doing phenomenon. By applying convex fractional programming results, we obtain necessary and sufficient conditions of an optimal solution. Some theorems are developed to determine retailer’s optimal ordering policies and numerical examples are given to illustrate these theorems. In addition, some managerial insights from the numerical examples are also concluded.

    The scramjet, which is the propulsion of hypersonic vehicle, has become the focus in many military developed countries. The ground tests play an important role in the research of scramjet. There is defect of test medium contamination (the thermochemical characteristic of the ground test medium is different from that of the flight medium) in existing ground test facilities for scramjet combustor experiment. To solve the problem of test medium contamination, the first clean air heated facility of China for scramjet combustor experiment is designed. The key technology of designing the clean air heated facility is summarized. By using bypass duct, combustor model is protected from high temperature. To reduce the switching time between main duct and bypass duct, solenoid valve and water-cooled system were used. Having centrosymmetric structure, the heat radiating area of the facility and heat loss of the facility are much lower than others. Clean air heated facility is adopted to conduct experiment, which is the first experiment of China in clean air inflow, research on hydrogen-fueled and ethylene-fueled ignition and combustion for scramjet combustor at different equivalence ratio. Successful ignition and sustained combustion of hydrogen has been achieved. Successful ethylene ignition and sustained main stream combustion is achieved with normal fuel injection and taking hydrogen as pilot flame. Experiment result shows that the wall pressure of combustor model rises when the equivalence ratio of hydrogen rises. As the wall pressure of combustor model rises, the pressure disturbance influences the shock train in the upstream.

    2015-06-01

    In previous decades, the vision-based navigation problem based on 2D imaging has been largely studied and applied in space, for rendezvous and docking, as well as rover navigation, or entry, descent and landing. By providing measurement of the third dimension (range), 3D camera technology looks a promising alternative for many applications. Stereoscopic camera is one option to measure the third coordinate, but relies on significant CPU capabilities, which are generally not available for space applications. Scanning LIDAR (LIght detection and ranging) is also an existing solution, but it is relatively large and heavy and the refresh rate, lifetime and reliability are mainly determined by moving parts. 3D time-of-flight (TOF) technology (including flash LIDARs) offers a reliable alternative. By illuminating a whole scene at a time and thus providing a whole array image, there is no need for complex processing nor moving mechanisms, which clearly appears as an advantage for space applications. This paper presents the ongoing study conducted under ESA contract in the field of 3D TOF technology. Its goal is to evaluate the suitability of a 3D TOF camera for space applications, to derive requirements and a preliminary design, and finally to create and test a breadboard model. Performance budget, cost, and a development plan of a versatile spatialized 3D TOF camera are also outputs of the study, in addition to a high-fidelity simulator, allowing further studies by generating representative images and depth maps. To fulfill this project, a European team has been created, gathering Thales Alenia Space, Terma and SINTEF.

    Green, Robert D.; Kissock, Barbara I.; Bennett, William R.

    2010-01-01

    This report documents the results of two system related analyses to support the Exploration Technology Development Program (ETDP) Energy Storage Project. The first study documents a trade study to determine the optimum Li-ion battery cell capacity for the ascent stage battery for the Altair lunar lander being developed under the Constellation Systems program. The battery cell capacity for the Ultra High Energy (UHE) Li-ion battery initially chosen as the target for development was 35 A-hr; this study concludes that a 19.4 A-hr cell capacity would be more optimum from a minimum battery mass perspective. The second study in this report is an assessment of available low temperature Li-ion battery cell performance data to determine whether lowering the operating temperature range of the Li-ion battery, in a rover application, could save overall system mass by eliminating thermal control system mass normally needed to maintain battery temperature within a tighter temperature limit than electronics or other less temperature sensitive components. The preliminary assessment for this second study indicates that the reduction in the thermal control system mass is negated by an increase in battery mass to compensate for the loss in battery capacity due to lower temperature operating conditions.

    DEFF Research Database (Denmark)

    Boom, Jan-Tjeerd; R. Dijstra, Bouwe

    This paper compares emissions trading based on a cap on total emissions (permit trading) and on relative standards per unit of output (credit trading). Two types of market structure are considered: perfect competition and Cournot oligopoly. We find that output, abatement costs and the number...... of firms are higher under credit trading. Allowing trade between permit-trading and credit-trading sectors may increase in welfare. With perfect competition, permit trading always leads to higher welfare than credit trading. With imperfect competition, credit trading may outperform permit trading....... Environmental policy can lead to exit, but also to entry of firms. Entry and exit have a profound impact on the performance of the schemes, especially under imperfect competition. We find that it may be impossible to implement certain levels of total industry emissions. Under credit trading several levels...

    2016-12-01

    Full Text Available The Yuanba Gasfield is a large gas field discovered by Sinopec in the Sichuan Basin in recent years, and another main exploration area for natural gas reserves and production increase after the Puguang Gasfield. The ultra-deep sour gas reservoir in the Yuanba Gasfield is characterized by complicated geologic structure, deep reservoirs and complex drilled formation, especially in the continental deep strata which are highly abrasive with low ROP (rate of penetration and long drilling period. After many years of drilling practice and technical research, the following six key drilling and completion technologies for this type reservoir are established by introducing new tools and technologies, developing specialized drill bits and optimizing drilling design. They are: casing program optimization technology for ROP increasing and safe well completion; gas drilling technology for shallow continental strata and high-efficiency drilling technology for deep high-abrasion continental strata; drilling fluid support technologies of gas–liquid conversion, ultra-deep highly-deviated wells and horizontal-well lubrication and drag reduction, hole stability control and sour gas contamination prevention; well cementing technologies for gas medium, deep-well long cementing intervals and ultra-high pressure small space; horizontal-well trajectory control technologies for measuring instrument, downhole motor optimization and bottom hole assembly design; and liner completion modes and completion string optimization technologies suitable for this gas reservoir. Field application shows that these key technologies are contributive to ROP increase and efficiency improvement of 7000 m deep horizontal wells and to significant operational cycle shortening.

  8. Emerging technology: A key enabler for modernizing pharmaceutical manufacturing and advancing product quality.

    Science.gov (United States)

    O'Connor, Thomas F; Yu, Lawrence X; Lee, Sau L

    2016-07-25

    Issues in product quality have produced recalls and caused drug shortages in United States (U.S.) in the past few years. These quality issues were often due to outdated manufacturing technologies and equipment as well as lack of an effective quality management system. To ensure consistent supply of safe, effective and high-quality drug products available to the patients, the U.S. Food and Drug Administration (FDA) supports modernizing pharmaceutical manufacturing for improvements in product quality. Specifically, five new initiatives are proposed here to achieve this goal. They include: (i) advancing regulatory science for pharmaceutical manufacturing; (ii) establishing a public-private institute for pharmaceutical manufacturing innovation; (iii) creating incentives for investment in the technological upgrade of manufacturing processes and facilities; (iv) leveraging external expertise for regulatory quality assessment of emerging technologies; and (v) promoting the international harmonization of approaches for expediting the global adoption of emerging technologies.

  10. Innovation under cap-and-trade programs.

    Science.gov (United States)

    Taylor, Margaret R

    2012-03-27

    Policies incentivizing the private sector to reach its innovative potential in "clean" technologies are likely to play a key role in achieving climate stabilization. This article explores the relationship between innovation and cap-and-trade programs (CTPs)--the world's most prominent climate policy instrument--through empirical evidence drawn from successful CTPs for sulfur dioxide and nitrogen oxide control. The article shows that before trading began for these CTPs, analysts overestimated the value of allowances in a pattern suggestive of the frequent a priori overestimation of the compliance costs of regulation. When lower-than-expected allowance prices were observed, in part because of the unexpected range of abatement approaches used in the lead-up to trading, emissions sources chose to bank allowances in significant numbers and reassess abatement approaches going forward. In addition, commercially oriented inventive activity declined for emissions-reducing technologies with a wide range of costs and technical characteristics, dropping from peaks before the establishment of CTPs to nadirs a few years into trading. This finding is consistent with innovators deciding during trading that their research and development investments should be reduced, based on assessments of future market conditions under the relevant CTPs. The article concludes with a discussion of the results and their implications for innovation and climate policy.

    Full Text Available The dolomite reservoirs of the Lower Cambrian Longwangmiao Fm in the Gaoshiti–Moxi area, Sichuan Basin, are deeply buried (generally 4400–4900 m, with high heterogeneity, making reservoir prediction difficult. In this regard, key seismic exploration technologies were developed through researches. Firstly, through in-depth analysis on the existing geologic, drilling, seismic data and available research findings, basic surface and subsurface structures and geologic conditions within the study area were clarified. Secondly, digital seismic data acquisition technologies with wide azimuth, wide frequency band and minor bins were adopted to ensure even distribution of coverage of target formations through optimization of the 3D seismic geometry. In this way, high-accuracy 3D seismic data can be acquired through shallow, middle and deep formations. Thirdly, well-control seismic data processing technologies were applied to enhance the signal-to-noise ratio (SNR of seismic data for deep formations. Fourthly, a seismic response model was established specifically for the Longwangmiao Fm reservoir. Quantitative prediction of the reservoir was performed through pre-stack geo-statistics. In this way, plan distribution of reservoir thicknesses was mapped. Fifthly, core tests and logging data analysis were conducted to determine gas-sensitive elastic parameters, which were then used in pre-stack hydrocarbon detection to eliminate the multiple solutions in seismic data interpretation. It is concluded that application of the above-mentioned key technologies effectively promote the discovery of largescale marine carbonate gas reservoirs of the Longwangmiao Fm.

    Wagner, G. A.; Kadereit, A.

    Geoarchaeology is a growing discipline in archaeological science. It aims at the natural environment as context of past human societies and at the interaction between both, the environment and man as part of a joint ecosystem. This topic is also of considerable concern of present societies. Like other historic sciences, geoarchaeology requires accurate chronologies. Since one deals in geoarchaeology predominantly with sediments and rocks, luminescence methods play a key role. This is demonstrated in two case studies from Phlious in southern Greece and Nasca in southern Peru. The results show clearly climatically triggered social developments and feedbacks to the environment.

    Electrical energy consumption of the residential sector is a crucial area of research that has in the past primarily focused on increasing the efficiency of household devices such as water heaters, dishwashers, air conditioners, and clothes washer and dryer units. However, the focus of this research is shifting as objectives such as developing the smart grid and ensuring that the power system remains reliable come to the fore, along with the increasing need to reduce energy use and costs. Load research has started to focus on mechanisms to support the power system through demand reduction and/or reliability services. The power system relies on matching generation and load, and day-ahead and real-time energy markets capture most of this need. However, a separate set of grid services exist to address the discrepancies in load and generation arising from contingencies and operational mismatches, and to ensure that the transmission system is available for delivery of power from generation to load. Currently, these grid services are mostly provided by generation resources. The addition of renewable resources with their inherent variability can complicate the issue of power system reliability and lead to the increased need for grid services. Using load as a resource, through demand response programs, can fill the additional need for flexible resources and even reduce costly energy peaks. Loads have been shown to have response that is equal to or better than generation in some cases. Furthermore, price-incentivized demand response programs have been shown to reduce the peak energy requirements, thereby affecting the wholesale market efficiency and overall energy prices. The residential sector is not only the largest consumer of electrical energy in the United States, but also has the highest potential to provide demand reduction and power system support, as technological advancements in load control, sensor technologies, and communication are made.

    Full Text Available The four diversion tunnels at Jinping II hydropower station represent the deepest underground project yet conducted in China, with an overburden depth of 1500–2000 m and a maximum depth of 2525 m. The tunnel structure was subjected to a maximum external water pressure of 10.22 MPa and the maximum single-point groundwater inflow of 7.3 m3/s. The success of the project construction was related to numerous challenging issues such as the stability of the rock mass surrounding the deep tunnels, strong rockburst prevention and control, and the treatment of high-pressure, large-volume groundwater infiltration. During the construction period, a series of new technologies was developed for the purpose of risk control in the deep tunnel project. Nondestructive sampling and in-situ measurement technologies were employed to fully characterize the formation and development of excavation damaged zones (EDZs, and to evaluate the mechanical behaviors of deep rocks. The time effect of marble fracture propagation, the brittle–ductile–plastic transition of marble, and the temporal development of rock mass fracture and damage induced by high geostress were characterized. The safe construction of deep tunnels was achieved under a high risk of strong rockburst using active measures, a support system comprised of lining, grouting, and external water pressure reduction techniques that addressed the coupled effect of high geostress, high external water pressure, and a comprehensive early-warning system. A complete set of technologies for the treatment of high-pressure and large-volume groundwater infiltration was developed. Monitoring results indicated that the Jinping II hydropower station has been generally stable since it was put into operation in 2014.

    Electrical energy consumption of the residential sector is a crucial area of research that has in the past primarily focused on increasing the efficiency of household devices such as water heaters, dishwashers, air conditioners, and clothes washer and dryer units. However, the focus of this research is shifting as objectives such as developing the smart grid and ensuring that the power system remains reliable come to the fore, along with the increasing need to reduce energy use and costs. Load research has started to focus on mechanisms to support the power system through demand reduction and/or reliability services. The power system relies on matching generation and load, and day-ahead and real-time energy markets capture most of this need. However, a separate set of grid services exist to address the discrepancies in load and generation arising from contingencies and operational mismatches, and to ensure that the transmission system is available for delivery of power from generation to load. Currently, these grid services are mostly provided by generation resources. The addition of renewable resources with their inherent variability can complicate the issue of power system reliability and lead to the increased need for grid services. Using load as a resource, through demand response programs, can fill the additional need for flexible resources and even reduce costly energy peaks. Loads have been shown to have response that is equal to or better than generation in some cases. Furthermore, price-incentivized demand response programs have been shown to reduce the peak energy requirements, thereby affecting the wholesale market efficiency and overall energy prices. The residential sector is not only the largest consumer of electrical energy in the United States, but also has the highest potential to provide demand reduction and power system support, as technological advancements in load control, sensor technologies, and communication are made.

    Yacht has become a fashionable way for entertainment. However, to obtain the precise location of a yacht docked at a port has become one of the concerns of a yacht manager. To deal with this issue, we adopt a positioning method based on the principle of binocular parallax and background difference in this paper. Binocular parallax uses cameras to get multi-dimensional perspective of the yacht based on geometric principle of imaging. In order to simplify the yacht localization problem, we install LED light indicator as the key point on a yacht. And let it flash at a certain frequency during day time and night time. After getting the distance between the LED and the cameras, locating the yacht is easy. Compared with other traditional positioning methods, this method is simpler and easier to implement. In this paper, we study the yacht positioning method using the LED indicator. Simulation experiment is done for a yacht model in the distance of 3 meters. The experimental result shows that our method is feasible and easy to implement with a small 15% positioning error.

    Prediction has become more and more difficult in mineral exploration, especially in the mature exploration environment such as Tongling copper district. For enhancing predictive discovery of hidden ore deposits in such mature environment, the key strategies which should be adopted include the innovation of the exploration models, application of the advanced exploration techniques and integration of multiple sets of information. The innovation of the exploration models should incorporate the new metallogenic concepts that are based on the geodynamic anatomization. The advanced techniques applied in the mature exploration environment should aim at the speciality and complexity of the geological setting and working environments. The information synthesis is to integrate multiple sets of data for giving a more credible and visual prospectivity map by using the geographic imformation system(GIS) and several mathematical methods, such as weight of evidence and fuzzy logic, which can extract useful information from every set of data as much as possible. Guided by these strategies, a predictive exploration in Fenghuangshan ore field of Tongling copper district was implemented, and a hidden ore deposit was discovered.

    The United States ranking among the world in science, technology, engineering, and mathematics (STEM) education is decreasing. To counteract this problem NASA has made it part of its mission to promote STEM education among the nation s youth. Mockups can serve as a great tool when promoting STEM education in America. The Orion Cockpit Working Group has created a new program called Students Shaping America s Next Space Craft (SSANS) to outfit the Medium Fidelity Orion Mockup. SSANS will challenge the students to come up with unique designs to represent the flight design hardware. There are two main types of project packages created by SSANS, those for high school students and those for university students. The high school projects will challenge wood shop, metal shop and pre-engineering classes. The university projects are created mainly for senior design projects and will require the students to perform finite element analysis. These projects will also challenge the undergraduate students in material selection and safety requirements. The SSANS program will help NASA in its mission to promote STEM education, and will help to shape our nations youth into the next generation of STEM leaders.

    Although the two first metabolic needs are based on simple molecule (i.e. oxygen and water), the third metabolic needs considered a tremendously large number and diversity of molecules: food. Today, physical chemical technologies do not allow to synthetize all the spectrum of molecules and biological processes have to be considered. Moreover, the raw material products by plants or by microorganisms are generally not directly edible or palatable and would need either transformation, assembly and/or storage. In other words the challenges of the food cannot be reduced to the plant production but need to include as well the complete chain, from the production conditions and the biomass quality up to the final edible products and its acceptance. In other words all the steps have to be considered and characterize. Today these challenges requires a high level of plants characterization. This round table part 4 would allow the participants to present some of their results and express some domain of activities. Re4serach for collaboration will be identified.

    Year 2000 will be remembered as an epoch making period between two Koreas. Korean nuclear industries became activated with the KEDO LWR main contracts entering into force in February, 2000. Respective design, manufacturing and construction activities are mobilized in accordance with the total project schedule of about 100 months. What started out as the nuclear power plant design standardization project in the early '80s, is now being implemented as repeat construction of KSNPs at Yonggwang and Ulchin sites as well as at Kumho site in the DPRK. However, the KEDO construction schedule and the past nuclear inconsistency issues are closely linked due to the nonproliferation concerns. In practice, the IAEA must come to the conclusion that the correctness and completeness must be fulfilled before delivery of the first key component for the KEDO LWR unit 1. While the IAEA verification process tends to focus on the nuclear materials accountancy control, longer term objective between two Koreas is bound to take the form of confidence building. It is necessary to analyse the nuclear research and production facilities in order to make proper evaluation of a nation's nuclear capabilities. Close assessment on development status of graphite moderated reactors and their operation history, spent fuel reprocessing facilities, and HEU production capabilities would be essential. In addition, illicit trafficking possibilities should be addressed. Chapter 1 describes the graphite moderated reactors in general; Chapter 2 describes various reprocessing processes and their detection capabilities; Chapter 3 contains possible uranium enrichment processes with their detection capabilities, and Chapter 4 summarizes the international treaties in illicit trafficking control with the IAEA database.

    This program was organized to focus on materials development issues critical to the acceleration of solid-state lighting, and was split into three major thrust areas: (1) study of dislocation density reduction for GaN grown on sapphire using 'cantilever epitaxy', and the impact of dislocation density on the performance of state-of-the-art high-power LEDs; (2) the evaluation of in situ techniques for monitoring gas phase chemistry and the properties of GaN-based layers during metal-organic vapor phase epitaxy (MOCVD), and (3) feasibility for using semiconductor nanoparticles ('quantum dots') for the down-conversion of blue or ultraviolet light to generate white light. The program included a partnership between Lumileds Lighting (epitaxy and device fabrication for high power LEDs) and Sandia National Laboratories (cantilever epitaxy, gas phase chemistry, and quantum dot synthesis). Key findings included: (1) cantilever epitaxy can provide dislocation density reduction comparable to that of more complicated approaches, but all in one epitaxial growth step; however, further improvements are required to realize significant gains in LED performance at high drive currents, (2) in situ tools can provide detailed knowledge about gas phase chemistry, and can be used to monitor and control epitaxial layer composition and temperature to provide improved yields (e.g., a fivefold increase in color targeting is demonstrated for 540nm LEDs), and (3) quantum efficiency for quantum dots is improved and maintained up to 70% in epoxy thin films, but further work is necessary to increase densification (absorption) and robustness before practical application to LEDs.

    Full Text Available An inventory system for deteriorating items, with ramp-type demand rate, under two-level trade credit policy taking account of preservation technology is considered. The objective of this study is to develop a deteriorating inventory policy when the supplier provides to the retailer a permissible delay in payments, and during this credit period, the retailer accumulates the revenue and earns interest on that revenue; also the retailer invests on the preservation technology to reduce the rate of product deterioration. Shortages are allowed and partially backlogged. Sufficient conditions of the existence and uniqueness of the optimal replenishment policy are provided, and an algorithm, for its determination, is proposed. Numerical examples draw attention to the obtained results, and the sensitivity analysis of the optimal solution with respect to leading parameters of the system is carried out.

    2016-01-01

    Over the last 55 years, NASA has evolved life support for crewed space exploration vehicles from simple resupply during Project Mercury to the complex and highly integrated system of systems aboard the International Space Station. As NASA targets exploration destinations farther from low Earth orbit and mission durations of 500 to 1000 days, life support systems must evolve to meet new requirements. In addition to having more robust, reliable, and maintainable hardware, limiting resupply becomes critical for managing mission logistics and cost. Supplying a crew with the basics of food, water, and oxygen become more challenging as the destination ventures further from Earth. Aboard ISS the Atmosphere Revitalization Subsystem (ARS) supplies the crew's oxygen demand by electrolyzing water. This approach makes water a primary logistics commodity that must be managed carefully. Chemical reduction of metabolic carbon dioxide (CO2) provides a method of recycling oxygen thereby reducing the net ARS water demand and therefore minimizing logistics needs. Multiple methods have been proposed to achieve this recovery and have been reported in the literature. However, depending on the architecture and the technology approach, "oxygen recovery" can be defined in various ways. This discontinuity makes it difficult to compare technologies directly. In an effort to clarify community discussions of Oxygen Recovery, we propose specific definitions and describe the methodology used to arrive at those definitions. Additionally, we discuss key performance parameters for Oxygen Recovery technology development including challenges with comparisons to state-of-the-art.

    With the rapid development of Internet electr onic commerce has been n oticed increasingly. However, the problem of its security makes people not dare into this advanced field. The subjects involving in electronic commerce activiti es need to prevent the other subjects from denying their activities. Some securi ty organizations of government also need to get the encrypted key through legal means in order to track, intercept and capture criminal information. Thus the en crypted key escrow technology must be adopted and it must be of security. For th e sake of security the key will be divided into several blocks which are stored in different reliable agents. The key can not be restored unless all agents w ork together. For designing an effective and safe key escrow, the discrete logar ithm is applied for solving key escrow .The security of this algorithm completel y depends on the difficulty to solve discrete logarithm ,therefore, this algorit hm is secure and simple when a big prime number is adopted.Moreover, adding thi s technology in SET will benefit the legal agency to monitor illegal activitie s.%电子商务随着Internet的迅速发展,日益受到人们的关注。但其安全问题经常令人不敢涉足其中。一方面参加商务活动的主体需防止另一方抵赖活动,另一方面政府安全机构为跟踪截获犯罪嫌疑人员的通信,都需要通过合法渠道获得电子商务中商务活动的主体进行数据通讯时的加密密钥。此时需采用密钥托管技术,而且密钥托管必须是安全的。为了安全起见,密钥被分成几块,分别存在几位可信赖的委托人处进行托管,任何一位委托人都不能单独恢复密钥。只有几位委托人在一起才能回复密钥。为了有效安全的进行密钥托管,采用了离散对数解决密钥托管。鉴于本算法的安全性依赖与求离散对数的困难性,所以当选用很大的安全素数时,此算法既简单又安全。

    Anaerobic membrane bioreactors (AnMBRs) enable energy recovery from wastewater while simultaneously achieving high levels of treatment. The objective of this study was to elucidate how detailed design and operational decisions of submerged AnMBRs influence the technological, environmental, and economic sustainability of the system across its life cycle. Specific design and operational decisions evaluated included: solids retention time (SRT), mixed liquor suspended solids (MLSS) concentration, sludge recycling ratio (r), flux (J), and specific gas demand per membrane area (SGD). The possibility of methane recovery (both as biogas and as soluble methane in reactor effluent) and bioenergy production, nutrient recovery, and final destination of the sludge (land application, landfill, or incineration) were also evaluated. The implications of these design and operational decisions were characterized by leveraging a quantitative sustainable design (QSD) framework which integrated steady-state performance modeling across seasonal temperatures (using pilot-scale experimental data and the simulating software DESASS), life cycle cost (LCC) analysis, and life cycle assessment (LCA). Sensitivity and uncertainty analyses were used to characterize the relative importance of individual design decisions, and to navigate trade-offs across environmental, economic, and technological criteria. Based on this analysis, there are design and operational conditions under which submerged AnMBRs could be net energy positive and contribute to the pursuit of carbon negative wastewater treatment.

  11. Interspecific Competition and Trade-offs in Resource Allocation are the Key to Successful Growth of Seedlings of White Spruce (Picea glauca (Moench) Voss) at Subarctic Treelines in Warming Alaska.

    2015-12-01

    Alpine treelines in Alaska have advanced for the past 50 years in response to the recent climate warming. However, further increases in temperatures may cause treeline species drought stress and increase susceptibility to insect outbreaks and fire. Complex factors such as soil conditions and plant species composition also impact the growth of seedlings, which are essential to sustain boreal forests. Our goals were to assess 1) the current optimal elevation for the treeline species Picea glauca (white spruce) seedlings and how it is altered by climate change, and 2) their growth/survival strategies at each environmental site. We studied the growth response of spruce seedlings along an altitudinal gradient at 6 sites, consisting of tundra, forest, or transitional ecotone in Denali National Park and one forest site in Fairbanks, AK. In May 2012, four-month old seedlings were planted with or without naturally occurring plants to compare the presence or absence of the interspecific interaction. Summer temperatures were increased by one small greenhouse per site. Over 2 growing seasons, growth was measured non-destructively, and then the seedlings were harvested. Relative growth rate (RGR) in height was increased significantly as the altitude was increased. Elevated temperature increased height only in seedlings at a high-altitude forest. Seedlings with neighboring plants had a higher RGR in height than seedlings that had neighbors removed, while significantly wider diameters were measured from the seedlings without neighbors. A weak trend of declining diameter width with increasing altitudes was seen. Seedlings that grew taller did not grow their stems wider, indicating trade-offs in resource allocation. None of the altitudinal sites had a clear advantage for the growth of the seedlings. Habitat microclimate and the interaction with other species could be more important than the altitude or temperatures and hence, key to the survival and growth of spruce seedlings in

    本文构建了一个扩展的南北贸易模型,将北方创新、南方模仿和进口产品隐性技术作为内生变量,分析进口国如何选择模仿策略以最大程度地获得进口产品的内生技术溢出效应.结果表明,进口产品中隐性技术含量会影响南方厂商的模仿策略:进口产品隐性技术含量低时,原始模仿是南方厂商的理性选择;进口产品隐性技术产量较高时,南方厂商的模仿策略取决于模仿的预期边际收益与单位模仿成本的对比关系:模仿的预期边际收益大于单位模仿成本时,内生模仿是南方厂商的最优选择,反之原始模仿.%The paper builds an expanded the trade model between the south and the north of Chins, involving the northern innovation, the southern imitation and tacit technology in the model as endogenous variables.Then the paper analyses how importers imitate the imported products to get optimal technology spillover effect.The theoretical analysis shows that the southern manufacturers' imitating strategy may be affected by tacit technology hidden within the imported products.If the content of tacit technology is low within the imported products, simple imitation is the southern manufacturers' optimal imitating strategy.And when the content of tacit technology is high, southern manufacturers' optimal imitating strategy depends on the relative relationship of imitation' s marginal revenue and unit imitating cost.When the imitation' s marginal revenue is higher than unit imitating cost, endogenous imitation is optimal for southern manufacturers, otherwise simple imitation.

  5. Water Resource Impacts Embedded in the Western US Electrical Energy Trade; Current Patterns and Adaptation to Future Drought

    Adams, E. A.; Herron, S.; Qiu, Y.; Tidwell, V. C.; Ruddell, B. L.

    2013-12-01

    Water resources are a key element in the global coupled natural-human (CNH) system, because they are tightly coupled with the world's social, environmental, and economic subsystems, and because water resources are under increasing pressure worldwide. A fundamental adaptive tool used especially by cities to overcome local water resource scarcity is the outsourcing of water resource impacts through substitutionary economic trade. This is generally understood as the indirect component of a water footprint, and as ';virtual water' trade. This work employs generalized CNH methods to reveal the trade in water resource impacts embedded in electrical energy within the Western US power grid, and utilizes a general equilibrium economic trade model combined with drought and demand growth constraints to estimate the future status of this trade. Trade in embedded water resource impacts currently increases total water used for electricity production in the Western US and shifts water use to more water-limited States. Extreme drought and large increases in electrical energy demand increase the need for embedded water resource impact trade, while motivating a shift to more water-efficient generation technologies and more water-abundant generating locations. Cities are the largest users of electrical energy, and in the 21st Century will outsource a larger fraction of their water resource impacts through trade. This trade exposes cities to risks associated with disruption of long-distance transmission and distant hydrological droughts.

  9. Research to practice in addiction treatment: key terms and a field-driven model of technology transfer.

    Science.gov (United States)

    2011-09-01

    The transfer of new technologies (e.g., evidence-based practices) into substance abuse treatment organizations often occurs long after they have been developed and shown to be effective. Transfer is slowed, in part, due to a lack of clear understanding about all that is needed to achieve full implementation of these technologies. Such misunderstanding is exacerbated by inconsistent terminology and overlapping models of an innovation, including its development and validation, dissemination to the public, and implementation or use in the field. For this reason, a workgroup of the Addiction Technology Transfer Center (ATTC) Network developed a field-driven conceptual model of the innovation process that more precisely defines relevant terms and concepts and integrates them into a comprehensive taxonomy. The proposed definitions and conceptual framework will allow for improved understanding and consensus regarding the distinct meaning and conceptual relationships between dimensions of the technology transfer process and accelerate the use of evidence-based practices.

    2001-11-01

    As part of a larger task, the Idaho National Engineering and Environmental Laboratory (INEEL) was tasked to perform a trade study comparing liquid-metal cooled reactors having Rankine power conversion systems with gas-cooled reactors having Brayton power conversion systems. This report summarizes the approach, the methodology, and the results of that trade study. Findings suggest that either approach has the possibility to approach the target specific mass of 3-5 kg/kWe for the power system, though it appears either will require improvements to achieve that. Higher reactor temperatures have the most potential for reducing the specific mass of gas-cooled reactors but do not necessarily have a similar effect for liquid-cooled Rankine systems. Fuels development will be the key to higher reactor operating temperatures. Higher temperature turbines will be important for Brayton systems. Both replacing lithium coolant in the primary circuit with gallium and replacing potassium with sodium in the power loop for liquid systems increase system specific mass. Changing the feed pump turbine to an electric motor in Rankine systems has little effect. Key technologies in reducing specific mass are high reactor and radiator operating temperatures, low radiator areal density, and low turbine/generator system masses. Turbine/generator mass tends to dominate overall power system mass for Rankine systems. Radiator mass was dominant for Brayton systems.

    International trade has an impact on national CO{sub 2} emissions and consequently on the ability to fulfil national CO{sub 2} reduction targets. Through goods and services traded in a globally interdependent world, the consumption in each country is linked to greenhouse gas emissions in other countries. It has been argued that in order to achieve equitable reduction targets, international trade has to be taken into account when assessing nations' responsibility for abating climate change. Especially for open economies such as Denmark, greenhouse gases embodied in international traded commodities can have a considerable influence on the national greenhouse gas responsibility. Founded in the concepts of 'producer CO{sub 2} responsibility', 'consumer CO{sub 2} responsibility' and 'CO{sub 2} trade balance' the aim of the present study has been to develop the single-region input-output model as used in a previous study into a multi-region input-output model in order to get a more realistic description of the production technologies actually used in the countries of imports. The study concludes that trade is the key to define CO{sub 2} responsibility on macroeconomics level and that imports should be founded in a multi-region model approach. The study also points at the need to consider the impact from foreign trade when negotiating national reduction targets and base line scenarios within the context of international climate agreements.

    2014-04-01

    Full Text Available A growing number of scholarly studies in and outside South Asia suggest the linkage between trade, economic development and peace between India and Pakistan. Despite many tangible political and economic gains of expanded India-Pakistan trade, the level of trade between India and Pakistan has remained anemic over the past six decades. Why hasn’t trade grown between India and Pakistan? What are the prospects of trade expansion between these two countries? Drawing on the growing political economy literature, we have identified four facilitating conditions to explain the growth of trade flows between a given pair of countries: distance, trade complementarity, rivalry, and government strength. In this article, we examine the dynamics and implications of these four conditions for trade relations between India and Pakistan. Following this analysis, we identify several key issues - trade liberalization, market access, energy cooperation, and regional stability - that can provide impetus needed to drive these two countries toward greater trade expansion.

    2009-01-01

    Future long duration manned space flights beyond low earth orbit will require the food system to remain safe, acceptable, and nutritious while efficiently balancing appropriate vehicle resources such as mass, volume, power, water, and crewtime. Often, this presents a challenge since maintaining the quality of the food system can result in a higher mass and volume. The Orion vehicle is significantly smaller than the Shuttle vehicle and the International Space Station and the mass and volume available for food is limited. Therefore, the food team has been challenged to reduce the mass of the packaged food from 1.82 kg per person per day to 1.14 kg per person per day. Past work has concentrated on how to reduce the mass of the packaging which contributes to about 15% of the total mass of the packaged food system. Designers have also focused on integrating and optimizing the Orion galley equipment as a system to reduce mass. To date, there has not been a significant effort to determine how to reduce the food itself. The objective of this project is to determine how the mass and volume of the packaged food can be reduced while maintaining caloric and hydration requirements. The following tasks are the key elements to this project: (1) Conduct further analysis of the ISS Standard Menu to determine moisture, protein, carbohydrate, and fat levels. (2) Conduct trade studies to determine how to bring the mass of the food system down. Trade studies may include removing the water of the total food system and/or increasing the fat content. (3) Determine the preferred method for delivery of the new food (e.g. bars, or beverages) and the degree of replacement. (4) Determine whether there are commercially available products that meet the requirements. By the end of this study, an estimate of the mass and volume savings will be provided to the Constellation Program. In addition, if new technologies need to be developed to achieve the mass savings, the technologies, timeline, and

  1. Entropy of international trades

    Science.gov (United States)

    Oh, Chang-Young; Lee, D.-S.

    2017-05-01

    The organization of international trades is highly complex under the collective efforts towards economic profits of participating countries given inhomogeneous resources for production. Considering the trade flux as the probability of exporting a product from a country to another, we evaluate the entropy of the world trades in the period 1950-2000. The trade entropy has increased with time, and we show that it is mainly due to the extension of trade partnership. For a given number of trade partners, the mean trade entropy is about 60% of the maximum possible entropy, independent of time, which can be regarded as a characteristic of the trade fluxes' heterogeneity and is shown to be derived from the scaling and functional behaviors of the universal trade-flux distribution. The correlation and time evolution of the individual countries' gross-domestic products and the number of trade partners show that most countries achieved their economic growth partly by extending their trade relationship.

    Based on data of regional FDI and inter-commodity trades, this article studies the affective aspects on domestic innovation in two contexts of introduced advanced technique and inward FDI simulated by Triangle Trade Pattern. It finds that, absorptive capacities determine local creative activities. Low level of industrial correlation hampers knowledge spillage through FDI in high-tech region. Existing technology stock satisfies tech- nical requirements of imported parts and components rather than imported capital goods, which make the digested or absorptive spillovers from the latter less. China benefits a lot from spillovers of components primarily impor- ted from Asian economies. Governments should increase R&D financial support in machinery and equipment in- dustry and import more parts from European countries and USA for wide spillover-absorptive activities favoring balanced bilateral trade.%本文采用地区细分的贸易和投资数据,从技术引进、吸引外商直接投资(FDI)两大路径研究“新三角贸易”模式下知识外溢对本土创新绩效的影响。研究表明:吸收能力是影响本土创新的关键因素;产业关联度低是制约高技术领域FDI知识溢出的重要原因。

    Full Text Available The article considers the problem of consequences of membership in the World Trade Organisation (WTO for Ukraine in foreign trade of high-technology products under conditions of co-operation with EU countries and the Customs Union of Belarus, Kazakhstan and Russia (CU. The article shows that after Ukraine joined WTO there were some rather significant reductions of tariff rates for Ukrainian products and liberalisation of access to the world markets, at the same time the internal Ukrainian market became more open for imported products. The article studies specific features and changes in the high-technology products market after Ukraine joined WTO. It analyses dynamics of volumes and specific weight of the world export-import of high-technology products and the structure of the world export and import of high technology products, including by individual countries and groups. The article makes a conclusion about a weak high-technology component of the Ukrainian export. It studies the structure of export of high-technology products of EU, CU and Ukraine. It shows that in order to develop the high-technology products market Ukraine needs to develop foreign trade with EU countries and also to continue co-operation with CU countries, in particular, with Russia. The article shows that the aerospace industry products takes the biggest specific weight in the export of high-technology products of Ukraine. It considers prospects of development of civil aircraft production in the world and Ukraine under the modern conditions. It analyses strengths and weaknesses of the aircraft construction industry and also threats and opportunities for aircraft construction of Ukraine due to external environment influence.

  14. International red meat trade.

    Science.gov (United States)

    Brester, Gary W; Marsh, John M; Plain, Ronald L

    2003-07-01

    The maturation of the US beef and pork markets and increasing consumer demands for convenience, safety, and nutrition suggests that the beef and pork industries must focus on product development and promotion. New marketing arrangements are developing that help coordinate production with consumer demands. The relative high levels of incomes in the United States are likely to increase the demands for branded products rather than increase total per capita consumption. Foreign markets represent the greatest opportunity for increased demand for commodity beef and pork products. Increasing incomes in developing countries will likely allow consumers to increase consumption of animal-source proteins. Real prices of beef and pork have declined substantially because of sagging domestic demand and increasing farm-level production technologies. Increasing US beef and pork exports have obviated some of the price declines. Pork attained a net export position from a quantity perspective in 1995. The United States continues to be a net importer of beef on a quantity basis but is close to becoming a net exporter in terms of value. By-products continue to play a critical role in determining the red meat trade balance and producer prices. The United States, however, must continue to become cost, price, and quality competitive with other suppliers and must secure additional market access if it is to sustain recent trade trends. Several trade tensions remain in the red meat industry. For example, mandated COOL will undoubtedly have domestic and international effects on the beef and pork sectors. Domestically, uncertainty regarding consumer demand responses or quality perceptions regarding product origin, as well as added processor-retailer costs will be nontrivial. How these factors balance out in terms of benefits versus costs to the industry is uncertain. From an international perspective, some beef and pork export suppliers to the United States could view required labeling as a

    Pagano, T. S.

    2016-12-01

    Hyperspectral infrared sounding of the atmosphere has become a vital element in the observational system for weather forecast prediction at National Weather Prediction (NWP) centers worldwide. The NASA Atmospheric Infrared Sounder (AIRS) instrument was the pathfinder for the hyperspectral infrared observations and was designed to provide accurate atmospheric temperature and water vapor profile information in support of weather prediction. AIRS was launched in 2002 and continues to operate well. The Cross-track Infrared Sounder (CrIS) on the Suomi NPP satellite was launched in 2011 to continue the AIRS measurement record. CrIS also continues to operate well and additional sensors are planned for launch promising to continue the hyperspectral infrared measurements in support of NWP into the late 2030's. The high cost of IR sounders makes it costly to launch them into multiple orbits to improve temporal sampling, or into GEO, although EUMETSAT is planning a GEO IR Sounder to launch in the early 2020's. JPL NASA is offering an alternate hyperspectral IR sounder architecture for the future involving CubeSats. The latest technology in large format focal plane assemblies, wide field optics and active cryocoolers enables a reduction in size, mass and cost of the legacy sounders and offer new configurations. Lessons learned from AIRS and CrIS indicate that temperature and water vapor sounding in the lower troposphere can be achieved with only the MWIR portion of the spectrum. The CubeSat Infrared Atmospheric Sounder (CIRAS) employs only an MWIR spectrometer to achieve lower tropospheric temperature and water vapor profiles, but with comparable spatial, spectral and radiometric sensitivity in this band as AIRS and CrIS. CIRAS operates from 4.08-5.13 µm with 625 channels and spectral resolution of 1.2-2.0 cm-1. CIRAS employs an immersion grating spectrometer making the optics incredibly compact, and HOT-BIRD detectors enabling good uniformity and operability over the large

  16. ICEHTMC 2015特别供稿专栏%Key Considerations for the Introduction of a Healthcare Technology Management Program in Remote Locations

    Institute of Scientific and Technical Information of China (English)

    J B Robson

    2016-01-01

    Establishment of a healthcare technology management program in remote locations requires the same consideration as programs in mainstream healthcare facilities but with an added emphasis on clarity of process, ownership of responsibility, management of resources and communication of roles. The author shares the experiences of clinical engineering personnel from the South Australian Biomedical Engineering Service (SA BME) based in Adelaide who are often required to travel thousands of kilometers by road to provide onsite assistance at over 100 rural and city sites. Effective remote service delivery requires a reliance on site based healthcare workers and local contractors to help manage the clinical engineering issues and risks associated with owning or using healthcare technology with an added role for SA BME staff to manage, foster and regulate this assistance. This paper outlines the policy document published throughout South Australia by the state government’s health department, directing all stakeholders involved in the use and ownership of healthcare technology on their role in the Management of Healthcare Technology. With an emphasis on assuring this technology is safe, effective, available and compliant this policy directive is an example of an essential foundation document that should exist wherever clinical engineering services are applied including sites where no clinical engineering personnel are based. This paper outlines the key elements of this directive, how it was developed and how it is used to achieve clarity of process and ownership of roles. Of essential importance when establishing a healthcare technology management program is its nexus with relevant industry, country and global philosophies. In Australia fundamental technology management principles are collated through Standards Australia the nation's peak non-government Standards organization charged by the Commonwealth Government to meet Australia's need for contemporary, internationally

    Directory of Open Access Journals (Sweden)

    Giordano Urbini

    2015-01-01

    Full Text Available The environment and the health of mankind are subject to strong pressures from pollutants. The ambition of a better quality of life is often frustrated by the increase in emissions as a result of the increasing consumption of resources and energy to satisfy the growth of the world’s population and its expectations for socioeconomic development. At times, problems take on a planetary dimension, the best known example being greenhouse gas emission, with the resulting effects of climate change. Pollution highlights our failure to provide adequate education, which is essential if we are to become fully aware of problems and actively seek sustainable solutions. To this end, it is essential to set up an extended environmental and health education program in all communities that will accompany younger generations from the beginning of their education in order to make them conscious players in protecting the environment and their own health. The size of the problems requires that a joint effort be made at an international level in the political realm and in the scientific-cultural realm in order to share experiences and sensitivity and to seek joint solutions. It is necessary to assign an increasingly important role to scientific and technological innovation which, in the last century, from Marconi to Einstein to Fleming, to the most recent innovations in the fields of genomics and microchips, has allowed humanity to achieve a rate of growth of wellbeing never previously seen in its thousands of years of history. This innovation must rationally be entrusted with our expectations to provide a practical solution to the problems of pollution that threaten our everyday lives and the survival of the planet. This text discusses the types of progress most eagerly awaited in the fields of water supply, wastewater treatment, atmospheric pollution and waste disposal.

    Measures to improve the quality and sustainability of healthcare practice and provision have become a policy concern. In addition, the involvement of stakeholders in health policy decision-making has been advocated, as complex questions arise around the structure of funding arrangements in a context of limited resources. Using a case study of assisted reproductive technologies (ART), deliberative engagements with a range of stakeholder groups were held on the topic of how best to structure the distribution of Australian public funding in this domain. Deliberative engagements were carried out with groups of ART consumers, clinicians and community members. The forums were informed by a systematic review of ART treatment safety and effectiveness (focusing, in particular, on maternal age and number of treatment cycles), as well as by international policy comparisons, and ethical and cost analyses. Forum discussions were transcribed and subject to thematic analysis. Each forum demonstrated stakeholders' capacity to understand concepts of choice under resource scarcity and disinvestment, and to countenance options for ART funding not always aligned with their interests. Deliberations in each engagement identified concerns around 'equity' and 'patient responsibility', culminating in a broad preference for (potential) ART subsidy restrictions to be based upon individual factors rather than maternal age or number of treatment cycles. Community participants were open to restrictions based upon measures of body mass index (BMI) and smoking status, while consumers and clinicians saw support to improve these factors as part of an ART treatment program, as distinct from a funding criterion. All groups advocated continued patient co-payments, with measures in place to provide treatment access to those unable to pay (namely, equity of access). Deliberations yielded qualitative, socially-negotiated evidence required to inform ethical, accountable policy decisions in the specific

  9. Melting ice, growing trade?

    Directory of Open Access Journals (Sweden)

    Sami Bensassi

    2016-05-01

    Full Text Available Abstract Large reductions in Arctic sea ice, most notably in summer, coupled with growing interest in Arctic shipping and resource exploitation have renewed interest in the economic potential of the Northern Sea Route (NSR. Two key constraints on the future viability of the NSR pertain to bathymetry and the future evolution of the sea ice cover. Climate model projections of future sea ice conditions throughout the rest of the century suggest that even under the most “aggressive” emission scenario, increases in international trade between Europe and Asia will be very low. The large inter-annual variability of weather and sea ice conditions in the route, the Russian toll imposed for transiting the NSR, together with high insurance costs and scarce loading/unloading opportunities, limit the use of the NSR. We show that even if these obstacles are removed, the duration of the opening of the NSR over the course of the century is not long enough to offer a consequent boost to international trade at the macroeconomic level.

    Scherer, Artur; Tittel, Wolfgang

    2010-01-01

    We develop a model for practical, entanglement-based long-distance quantum key distribution employing entanglement swapping as a key building block. Relying only on existing off-the-shelf technology, we show how to optimize resources so as to maximize secret key distribution rates. The tools comprise lossy transmission links, such as telecom optical fibers or free space, parametric down-conversion sources of entangled photon pairs, and threshold detectors that are inefficient and have dark counts. Our analysis provides the optimal trade-off between detector efficiency and dark counts, which are usually competing, as well as the optimal source brightness that maximizes the secret key rate for specified distances (i.e. loss) between sender and receiver.

    Full Text Available In terms of marketing, online trading is a new distribution channel and trading platforms are products of Investment and Financial Services Companies. Internet shortens the connection between the investor and the products they wish to purchase (shares, futures, CFDs, government securities, bonds, etc., and in some cases it no longer needs a security broker. Increasing use of the Internet and increasing competitiveness between Investment and Financial Services Companies do the latter, to seek new distribution channels to specific products. The purpose of this paper is to examine to what extent the investor education level affects the decision to move from traditional trading to online trading and the benefits and disadvantages of these types of transactions. To whom should the Investment and Financial Services Companies guide their marketing campaign to attract more investors for online platforms? The work presented is part of a larger project that will be part of author thesis, studying other factors that influence the decision to move from traditional to online trading: cost factor, time factor, psychological and social attributes of investors, yield portfolios and technological capacities of Investment and Financial Services Companies. Starting from the idea that with the increase of experience in stock investments the investors will want to make their own decisions, Investment and Financial Services Companies should provide new products. Compared to competitors, an Investment and Financial Services Company must innovate, and information technology currently offers the tools for innovation facilities. At the same time, the existence and development of the Internet has made the transaction without assistance or with minimal human intervention possible (Voss, 2000. The difference is in the knowledge about stock market, the speed the transaction orders arrive in the stock market, direct access to multiple markets, transaction costs and the level

    Trade in agricultural commodities has created increasingly complex linkages between resource use and food supplies across national borders. Understanding the degree to which food production and consumption relies on trade is vital to understanding how to sustainably meet growing food demands across scales. We use detailed bilateral trade statistics and data on agricultural management to examine the land use and water consumption embodied in agricultural trade, which we relate to basic nutritional indicators to show how trade contributes to food availability worldwide. Agricultural trade carries enough calories to provide >1.7 billion people a basic diet each year. We identify key commodities and producer-consumer relationships that disproportionately contribute to embodied resource use and flows of food nutrition at the global scale. For example, just 15 disproportionately large soybean trades comprised ~10% the total harvested area embodied in export production. We conclude by framing these results in terms of the fraction of each country's food production and consumption that is linked to international trade. These findings help to characterize how countries allocate resources to domestic versus foreign food demand.

  4. Framing international trade and chronic disease.

    Science.gov (United States)

    Labonté, Ronald; Mohindra, Katia S; Lencucha, Raphael

    2011-07-04

    There is an emerging evidence base that global trade is linked with the rise of chronic disease in many low and middle-income countries (LMICs). This linkage is associated, in part, with the global diffusion of unhealthy lifestyles and health damaging products posing a particular challenge to countries still facing high burdens of communicable disease. We developed a generic framework which depicts the determinants and pathways connecting global trade with chronic disease. We then applied this framework to three key risk factors for chronic disease: unhealthy diets, alcohol, and tobacco. This led to specific 'product pathways', which can be further refined and used by health policy-makers to engage with their country's trade policy-makers around health impacts of ongoing trade treaty negotiations, and by researchers to continue refining an evidence base on how global trade is affecting patterns of chronic disease. The prevention and treatment of chronic diseases is now rising on global policy agendas, highlighted by the UN Summit on Noncommunicable Diseases (September 2011). Briefs and declarations leading up to this Summit reference the role of globalization and trade in the spread of risk factors for these diseases, but emphasis is placed on interventions to change health behaviours and on voluntary corporate responsibility. The findings summarized in this article imply the need for a more concerted approach to regulate trade-related risk factors and thus more engagement between health and trade policy sectors within and between nations. An explicit recognition of the role of trade policies in the spread of noncommunicable disease risk factors should be a minimum outcome of the September 2011 Summit, with a commitment to ensure that future trade treaties do not increase such risks.

    2015-04-01

    Full Text Available Where approved, producers have adopted genetically modified (GM crops extensively. Yet, areas not adopting GM crops account for large shares of production and consumption. GM crops differ from previous agricultural innovations because consumers may perceive them as fundamentally different from (and potentially inferior to conventionally grown crops. Many countries maintain restrictions on production and importation of GM crops. GM crop adoption affects producers and consumers, not only through technological change, but also through trade policy responses. This article reviews open economy analyses of impacts of GM crops. To varying degrees, commodities are segmented into GM, conventionally grown, and organic product markets. Recent advances in trade modeling consider the consequences of market segmentation, along with consequences of GM crop import restrictions, product segregation requirements, and coexistence policies.

  20. Trade in health services.

    Science.gov (United States)

    Chanda, Rupa

    2002-01-01

    In light of the increasing globalization of the health sector, this article examines ways in which health services can be traded, using the mode-wise characterization of trade defined in the General Agreement on Trade in Services. The trade modes include cross- border delivery of health services via physical and electronic means, and cross-border movement of consumers, professionals, and capital. An examination of the positive and negative implications of trade in health services for equity, efficiency, quality, and access to health care indicates that health services trade has brought mixed benefits and that there is a clear role for policy measures to mitigate the adverse consequences and facilitate the gains. Some policy measures and priority areas for action are outlined, including steps to address the "brain drain"; increasing investment in the health sector and prioritizing this investment better; and promoting linkages between private and public health care services to ensure equity. Data collection, measures, and studies on health services trade all need to be improved, to assess better the magnitude and potential implications of this trade. In this context, the potential costs and benefits of trade in health services are shaped by the underlying structural conditions and existing regulatory, policy, and infrastructure in the health sector. Thus, appropriate policies and safeguard measures are required to take advantage of globalization in health services.
