    Standards of commodity classes of Chinese materia medica is an important way to solve the "Lemons Problem" of traditional Chinese medicine market. Standards of commodity classes are also helpful to rebuild market mechanisms for "high price for good quality". The previous edition of commodity classes standards of Chinese materia medica was made 30 years ago. It is no longer adapted to the market demand. This article researched progress on standards of commodity classes of Chinese materia medica. It considered that biological activity is a better choice than chemical constituents for standards of commodity classes of Chinese materia medica. It is also considered that the key point to set standards of commodity classes is finding the influencing factors between "good quality" and "bad quality". The article also discussed the range of commodity classes of Chinese materia medica, and how to coordinate standards of pharmacopoeia and commodity classes. According to different demands, diversiform standards can be used in commodity classes of Chinese materia medica, but efficacy is considered the most important index of commodity standard. Decoction pieces can be included in standards of commodity classes of Chinese materia medica. The authors also formulated the standards of commodity classes of Notoginseng Radix as an example, and hope this study can make a positive and promotion effect on traditional Chinese medicine market related research.

    The growing base of information about ecosystem services generated by ecologists, economists, and other scientists could improve the implementation, monitoring, and evaluation of commodity-sourcing standards being adopted by corporations to mitigate risk in their supply chains and achieve sustainability goals. This review examines various ways that information about ecosystem services could facilitate compliance with and auditing of commodity-sourcing standards. We also identify gaps in the current state of knowledge on the ecological effectiveness of sustainability standards and demonstrate how ecosystem-service information could complement existing monitoring efforts to build credible evidence. This paper is a call to the ecosystem-service scientists to engage in this decision context and tailor the information they are generating to the needs of the standards community, which we argue would offer greater efficiency of standards implementation for producers and enhanced effectiveness for standard scheme owners and corporations, and should thus lead to more sustainable outcomes for people and nature.

  4. From Public to Private Standards for Tropical Commodities: A Century of Global Discourse on Land Governance on the Forest Frontier

    Directory of Open Access Journals (Sweden)

    Derek Byerlee

    2015-04-01

    Full Text Available Globalization and commodity exports have a long history in affecting land use changes and land rights on the tropical forest frontier. This paper reviews a century of social and environmental discourse around land issues for four commodities grown in the humid tropics—rubber, cocoa, oil palm and bananas. States have exercised sovereign rights over land and forest resources and the outcomes for deforestation and land rights of existing users have been quite varied depending on local institutional contexts and political economy. In the current period of globalization, as land use changes associated with tropical commodities have accelerated, land issues are now at center stage in the global discourse. However, efforts to protect forests and the rights of local communities and indigenous groups continue to be ad hoc and codification of minimum standards and their implementation remains a work in progress. Given a widespread failure of state directed policies and institutions to curb deforestation and protect land rights, the private sector, with the exception of the rubber industry, is emphasizing voluntary standards to certify sustainability of their products. This is an important step but expectations that they will effectively address concerns about the impact of tropical commodities expansion might be too high, given their voluntary nature, demand constraints, and the challenge of including smallholders. It is also doubtful that private standards can more than partially compensate for long standing weaknesses in land governance and institutions on the forest frontier.

  5. International trade standards for commodities and products derived from animals: the need for a system that integrates food safety and animal disease risk management.

    A case is made for greater emphasis to be placed on value chain management as an alternative to geographically based disease risk mitigation for trade in commodities and products derived from animals. The geographic approach is dependent upon achievement of freedom in countries or zones from infectious agents that cause so-called transboundary animal diseases, while value chain-based risk management depends upon mitigation of animal disease hazards potentially associated with specific commodities or products irrespective of the locality of production. This commodity-specific approach is founded on the same principles upon which international food safety standards are based, viz. hazard analysis critical control points (HACCP). Broader acceptance of a value chain approach enables animal disease risk management to be combined with food safety management by the integration of commodity-based trade and HACCP methodologies and thereby facilitates 'farm to fork' quality assurance. The latter is increasingly recognized as indispensable to food safety assurance and is therefore a pre-condition to safe trade. The biological principles upon which HACCP and commodity-based trade are based are essentially identical, potentially simplifying sanitary control in contrast to current separate international sanitary standards for food safety and animal disease risks that are difficult to reconcile. A value chain approach would not only enable more effective integration of food safety and animal disease risk management of foodstuffs derived from animals but would also ameliorate adverse environmental and associated socio-economic consequences of current sanitary standards based on the geographic distribution of animal infections. This is especially the case where vast veterinary cordon fencing systems are relied upon to separate livestock and wildlife as is the case in much of southern Africa. A value chain approach would thus be particularly beneficial to under-developed regions of

  11. Commodities and Stock Investment

    Syed Jawad Hussain Shahzad

    2014-09-01

    Full Text Available This study is a multivariate analysis of commodities and stock investment in a newly established market scenario. Return distribution asymmetry is examined with higher order movements. Skewness in commodity future’s return is largely insignificant, whereas kurtosis is highly significant for both stock and commodity future contracts. Correlation analysis is done with Pearson’s and Kendall’s tau measures. Commodities provide significant diversification benefits when added in a portfolio of stocks. Compared with stocks, commodity future’s returns show stronger correlation with unexpected inflation. The volatility is measured through Glosten-Jagannathan-Runkle - Generalized Autoregressive Conditional Heteroskedasticity (GJR-GARCH model and reflects that commodities have inverted asymmetric behavior, that is, more impact from the upward shocks compared with downward. Stocks have asymmetric volatility, that is, more impact from negative shocks compared with positive. Gold has highest inverted asymmetric volatility. Tail dependence, measured through Student’s t copula, shows no combined downside movement. In conclusion, commodity investments provide diversification and inflation protection.

  12. Financialization of commodities

    Directory of Open Access Journals (Sweden)

    Michał Falkowski

    2011-12-01

    Full Text Available The basic theory of price formation tells us how the price of a particular asset will change based on the adjustment to its supply and demand. However, values of assets are also determined by other business fundamentals, company’s and world events, human psychology, and investors’ belief about the possible future profit. In recent history that lead to an increase of individual and institutional investors’ interest in allocating their resources in commodity markets. With a large inflow of capital commodities’ prices started to rise making them attractive components to effective investment portfolios. The presented paper addresses the issue of so called commodities ‘financialization’ process. It looks at the main factors standing behind commodities’ price movements and to what extent financial market participants contributed to commodities price volatility in recent years. Based on the data examined it distinguishes the involvement of both commercial and non-commercial traders in short and long term periods of time. As well as explaining the impact of growing investors’ interest in commodity markets it defines other market forces - like currency appreciations and emerging markets - as being part of increased volatility in raw and soft commodity markets. Along with market examination the paper focuses on possible future outcomes in attempts to regulate commodities derivatives markets and potential effects of those efforts.

    2009-01-01

    Each chapter of the 2009 edition of the U.S. Geological Survey (USGS) Mineral Commodity Summaries (MCS) includes information on events, trends, and issues for each mineral commodity as well as discussions and tabular presentations on domestic industry structure, Government programs, tariffs, 5-year salient statistics, and world production and resources. The MCS is the earliest comprehensive source of 2008 mineral production data for the world. More than 90 individual minerals and materials are covered by two-page synopses. For mineral commodities for which there is a Government stockpile, detailed information concerning the stockpile status is included in the two-page synopsis. Because specific information concerning committed inventory was no longer available from the Defense Logistics Agency, National Defense Stockpile Center, that information, which was included in earlier Mineral Commodity Summaries publications, has been deleted from Mineral Commodity Summaries 2009. National reserves and reserve base information for most mineral commodities found in this report, including those for the United States, are derived from a variety of sources. The ideal source of such information would be comprehensive evaluations that apply the same criteria to deposits in different geographic areas and report the results by country. In the absence of such evaluations, national reserves and reserve base estimates compiled by countries for selected mineral commodities are a primary source of national reserves and reserve base information. Lacking national assessment information by governments, sources such as academic articles, company reports, common business practice, presentations by company representatives, and trade journal articles, or a combination of these, serve as the basis for national reserves and reserve base information reported in the mineral commodity sections of this publication. A national estimate may be assembled from the following: historically reported

    The prospect of sustainable production of food ingredients from photoautotrophic microalgae was reviewed. Clearly, there is scope for microalgal oils to replace functions of major vegetable oils, and in addition to deliver health benefits to food products. Furthermore, with a limited production surface, a substantial portion of the European Union market could be supplied with edible oils and proteins from microalgae. Yet, before microalgal ingredients can become genuinely sustainable and cost effective alternatives for current food commodities, major breakthroughs in production technology and in biorefinery approaches are required. Moreover, before market introduction, evidence on safety of novel microalgal ingredients, is needed. In general, we conclude that microalgae have a great potential as a sustainable feedstock for food commodities.

    2011-01-01

    The California Leafy Greens Marketing Agreement (LGMA) was adopted in an effort to minimize the risk of contamination of leafy greens with enteric pathogens from a variety of sources, including ground and surface irrigation waters. The LGMA contains standards similar to those established for recreational waters, based on Escherichia coli concentrations. However, no correlation between E. coli and any specific waterborne pathogen(s) has been reported. We conducted this monitoring study in an agricultural watershed to (i) evaluate spatial and temporal fluctuations in E. coli populations and virulence genes associated with pathogenic E. coli and (ii) investigate whether a relationship could be established between E. coli and virulence genes. The virulence genes targeted for analysis were the eae and stx genes, encoding for intimin and Shiga-like toxins, respectively; they were detected with PCR methods. E. coli concentrations and eae and stx prevalence varied both spatially and temporally. In general, both were higher in agricultural than in forested areas and were higher in the summer and fall seasons than in winter. The eae and stx genes were prevalent throughout the watershed. However, in the absence of actual isolates, no conclusions could be drawn regarding the prevalence of specific pathogenic E. coli. No correlation was observed between E. coli concentrations and virulence genes; lower E. coli concentrations were not necessarily associated with decreased prevalence of eae and stx genes. These results suggest that the LGMA standards might not adequately address the issue of waterborne contamination, and that alternative criteria might be required.

Being an organized commodities and capital market, it goes beyond the trade in a trade fair and particular trade in real commodities. It includes trading in exchangeable goods by standard label. As foundation of commodities exchange is expected in Croatia, the paper will explicate its status and operation in Slovakia, an EU member state that is similar to our country. The paper will focus on the legal status and organizational structure of consumer goods market in Bratislava. Although it has existed for just over 15 years, it is important to note that it actually goes back to the pre-Second World War Czechoslovakia. Also, to provide better understanding of its functioning, regulations defining the foundation and functioning of the commodities market will also be presented as well as the profile, method and types of operations, together with its positive effects.

The consumption of silver for all fabrication uses is expected to grow slowly through the decade ending in 2010 at about 1.3 percent per year for the world and 2.4 percent per year for the United States. World and U.S. reserves and reserve bases are more than adequate to satisfy the demand for newly mined silver through 2010. The other components of supply will be silver recovered from scrap, silver from industrial stocks, and silver bullion that is sold into the market from commodity exchange and private stocks.

    2011-08-01

    The productivity of tropical agricultural commodities is affected by the health of the ecosystem. Shade tolerant crops such as coffee and cocoa benefit from environmental services provided by forested landscapes, enabling landscape design that meets biodiversity conservation and economic needs. What can motivate farmers to apply and maintain such landscape approaches? Rather than rely on a proliferation of externally funded projects new opportunities are emerging through the international market that buys these commodities. As part of their growing commitment to sustainable supply chains, major companies are supporting agroforestry approaches and requiring producers and traders to demonstrate that the source of their commodities complies with a set of principles that conserves forested landscapes and improves local livelihoods. The paper presents examples of international companies that are moving in this direction, analyzes why and how they are doing it and discusses the impact that has been measured in coffee and cocoa communities in Latin America and Africa. It particularly considers the role of standards and certification systems as a driver of this commitment to promote profitable operations, environmental conservation and social responsibility throughout the coffee and cocoa value chains. Such approaches are already being taken to scale and are no longer operating only in small niches of the market but the paper also considers the limitations to growth in this market-based approach.

    Aflatoxin (AF) B1, B2, G1 and G2 were determined in 120 samples of selected Thai commodities including unpolished rice, unpolished glutinous rice, chilli powder, whole dried chilli pods and raw peanut. The mean concentrations of the total AFs for analysed samples were 0.16, 25.43, 14.18, 6.62 and 1.43 µg kg(-1) with positive incidences of 4%, 20%, 97%, 37% and 30%, respectively. Quantitative analysis was performed using HPLC equipped with post-column derivatisation and fluorescence detection. Sample clean-up was carried out using immunoaffinity columns for selective enrichment of AFs. The method was validated by using certified reference material, which showed recoveries over 85%. The limit of detections (LODs) and limit of quantifications (LOQs) were in a range between 0.01-0.11 µg kg(-1) and 0.03-0.38 µg kg(-1), respectively. The results clearly demonstrated that AFs were detectable in different matrices. Chilli powder was found to have the highest level of AFs contamination followed by chilli pods, peanut and rice, respectively. However, among the selected commodities, unpolished rice contained only trace levels of AFB1 and AFB2. With regard to the fact that AFs are a natural contaminant in commodities, this report calls to attention the regular monitoring and effective control of food commodities to prevent health hazards.

    International community is trying to prevent the spread of WMD (Weapons of Mass Destruction), especially nuclear weapons. These efforts result in the declaration of UNSC Resolution 1540 in 2004, which made export controls the international norms for all nations in the world. Korea enacted Foreign Trade Act in 1989 to adhere to the export control standards worldwide. Export control system in Korea consists of commodity classification system and export license system. The commodity classification system is used to identify strategic commodity. The Export License system is used to verify that exports have met the conditions required by the international export control system. NSG guidelines, the NSG handbook and Public Notice on Trade of Strategic Items are used to classify items and technology However, some items or technology in NSG guidelines should be especially designed or prepared (EDP). It is difficult to determine which items or technology is strategic commodity because EDP criteria are qualitative. NSG or participant states don't provide clear criteria to classify items and technology but recommend establishing standards autonomously. Hence the result of deliberation on the same items and technology may be different by reviewer's experience, knowledge and governmental policy. It causes confusion of reviewers and export companies In this research, commodity classification systematization by EDP criteria's clarification was performed to increase consistency and efficiency.

  1. Analysis of Interregional Commodity Flows

    Directory of Open Access Journals (Sweden)

    Wirach Hirun

    2010-01-01

    Full Text Available Problem statement: Commodity Flow Survey (CFS was launched to collect comprehensive freight flow data throughout the kingdom of Thailand. The survey’s database is the most complete collection of commodity flow data in Thailand. The need to reveal interregional freight characteristics using available data from the CFS led to the objectives of this research. Approach: An origin destination matrix based on province was calibrated using a flexible Box-Cox function form. It used maximum likelihood and the backward method for calibration and Root Mean Square Error (RMSE and Mean Relative Error (MRE to verify the model’s performance. Independent variables were classified into three groups: origin variable, destination variable and geographic variable. The origin variable represented the behavior of the trip as generated at the place of origin. Some consumption occurred at the origin. The employment and the average plant size variables were selected for potential productivity while personal income per capita and total populations were included to explain consumption behavior at the origin. Personal income per capita and total populations were selected for destination variables which act as proxy for final demand at the destination. The third category, distance, was the most conventional friction variable for geographical variables. Results: The calibrated model revealed that origin income, origin average plant size and origin population performed poorly. Therefore these variables were eliminated. The best developed model included four strongly significant variables at a 5% level: origin employment, destination population, destination income per capita and distance. Conclusion: The results showed that the selected variables and the Box-Cox functional form were successful in explaining behavior of interregional freight transportation in Thailand. The developed model was the first interregional freight transportation model to be

  5. Aromatherapy Oils: Commodities, Materials, Essences

    Directory of Open Access Journals (Sweden)

    Ruth Barcan

    2014-08-01

    Full Text Available This article examines the essential oils that are the central tools of aromatherapy and uses them as a case study for different approaches to material culture. It considers the conceptual and political implications of thinking of essential oils as, in turn, commodities, materials and essences. I argue that both cultural studies and aromatherapy have something to learn from each other. Classic materialist approaches might do well to focus more attention on the material properties and effects of things. Aromatherapy, on the other hand, could benefit from the enriched political understanding associated with classic materialist critique. New materialist strains of cultural studies may also find the vibrancy of matter that underpins many CAM/New Age practices worthy of examination.

  10. Scientific Research: Commodities or Commons?

    Science.gov (United States)

    Vermeir, Koen

    2013-10-01

    Truth is for sale today, some critics claim. The increased commodification of science corrupts it, scientific fraud is rampant and the age-old trust in science is shattered. This cynical view, although gaining in prominence, does not explain very well the surprising motivation and integrity that is still central to the scientific life. Although scientific knowledge becomes more and more treated as a commodity or as a product that is for sale, a central part of academic scientific practice is still organized according to different principles. In this paper, I critically analyze alternative models for understanding the organization of knowledge, such as the idea of the scientific commons and the gift economy of science. After weighing the diverse positive and negative aspects of free market economies of science and gift economies of science, a commons structured as a gift economy seems best suited to preserve and take advantage of the specific character of scientific knowledge. Furthermore, commons and gift economies promote the rich social texture that is important for supporting central norms of science. Some of these basic norms might break down if the gift character of science is lost. To conclude, I consider the possibility and desirability of hybrid economies of academic science, which combine aspects of gift economies and free market economies. The aim of this paper is to gain a better understanding of these deeper structural challenges faced by science policy. Such theoretical reflections should eventually assist us in formulating new policy guidelines.

  11. Applications of GARCH models to energy commodities

    Science.gov (United States)

    Humphreys, H. Brett

    This thesis uses GARCH methods to examine different aspects of the energy markets. The first part of the thesis examines seasonality in the variance. This study modifies the standard univariate GARCH models to test for seasonal components in both the constant and the persistence in natural gas, heating oil and soybeans. These commodities exhibit seasonal price movements and, therefore, may exhibit seasonal variances. In addition, the heating oil model is tested for a structural change in variance during the Gulf War. The results indicate the presence of an annual seasonal component in the persistence for all commodities. Out-of-sample volatility forecasting for natural gas outperforms standard forecasts. The second part of this thesis uses a multivariate GARCH model to examine volatility spillovers within the crude oil forward curve and between the London and New York crude oil futures markets. Using these results the effect of spillovers on dynamic hedging is examined. In addition, this research examines cointegration within the oil markets using investable returns rather than fixed prices. The results indicate the presence of strong volatility spillovers between both markets, weak spillovers from the front of the forward curve to the rest of the curve, and cointegration between the long term oil price on the two markets. The spillover dynamic hedge models lead to a marginal benefit in terms of variance reduction, but a substantial decrease in the variability of the dynamic hedge; thereby decreasing the transactions costs associated with the hedge. The final portion of the thesis uses portfolio theory to demonstrate how the energy mix consumed in the United States could be chosen given a national goal to reduce the risks to the domestic macroeconomy of unanticipated energy price shocks. An efficient portfolio frontier of U.S. energy consumption is constructed using a covariance matrix estimated with GARCH models. The results indicate that while the electric

  20. Biofuel and Food-Commodity Prices

    Directory of Open Access Journals (Sweden)

    David Zilberman

    2012-09-01

    Full Text Available The paper summarizes key findings of alternative lines of research on the relationship between food and fuel markets, and identifies gaps between two bodies of literature: one that investigates the relationship between food and fuel prices, and another that investigates the impact of the introduction of biofuels on commodity-food prices. The former body of literature suggests that biofuel prices do not affect food-commodity prices, but the latter suggests it does. We try to explain this gap, and then show that although biofuel was an important contributor to the recent food-price inflation of 2001–2008, its effect on food-commodity prices declined after the recession of 2008/09. We also show that the introduction of cross-price elasticity is important when explaining soybean price, but less so when explaining corn prices.

  9. Will Commodity Properties Affect Seller's Creditworthy: Evidence in C2C E-commerce Market in China

    Science.gov (United States)

    Peng, Hui; Ling, Min

    This paper finds out that the credit rating level shows significant difference among different sub-commodity markets in E-commerce, which provides room for sellers to get higher credit rating by entering businesses with higher average credit level before fraud. In order to study the influence of commodity properties on credit rating, this paper analyzes how commodity properties affect average crediting rating through the degree of information asymmetry, returns and costs of fraud, credibility perception and fraud tolerance. Empirical study shows that Delivery, average trading volume, average price and complaint possibility have decisive impacts on credit performance; brand market share, the degree of standardization and the degree of imitation also have a relatively less significant effect on credit rating. Finally, this paper suggests that important commodity properties should be introduced to modify reputation system, for preventing credit rating arbitrage behavior where sellers move into low-rating commodity after being assigned high credit rating.

    2011-05-26

    Crunching large graphs is the basis of many emerging appli- cations, such as social network analysis and bioinformatics. Graph analytics algorithms exhibit little locality and therefore present significant performance challenges. Hardware multi- threading systems (e.g, Cray XMT) show that with enough concurrency, we can tolerate long latencies. Unfortunately, this solution is not available with commodity parts. Our goal is to develop a latency-tolerant system built out of commodity parts and mostly in software. The proposed system includes a runtime that supports a large number of lightweight contexts, full-bit synchronization and a memory manager that provides a high-latency but high-bandwidth global shared memory. This paper lays out the vision for our system, and justifies its feasibility with a performance analysis of the run- time for latency tolerance.

    2004-10-02

    International animal health standards designed to facilitate safe trade in livestock and livestock products are set by the Office International des Epizooties (OIE) under the Sanitary and Phytosanitary Agreement of the World Trade Organization (WTO) and documented in the OIE's Terrestrial Animal Health Code. A core principle of the Code is the need for countries to eradicate important transboundary animal diseases (TADs) to reduce the risk of exporting disease to trading partners. International food safety standards are set by the Codex Alimentarius Commission, administered jointly by the World Health Organization and the Food and Agriculture Organization of the United Nations. The goal of global eradication of most TADs is unachievable for the foreseeable future, other than in the case of rinderpest, and this prevents many countries, especially developing nations, from engaging in international trade under WTO rules. This paper proposes an alternative, commodity-based approach to the formulation of international animal health and food safety standards, based on the fact that different commodities pose very different risks when it comes to the spread of human and animal pathogens. Therefore, the risk mitigation strategies required are equally commodity-dependent. The authors conclude that more focused commodity standards would improve access to international markets for all countries, especially those in the developing world. For this objective to be realised, credible and independent certification is required.

This paper aims to analyze that what is the impact of per capita consumption on different household income group in Pakistan. In particular, per capita consumption of eleven (11 different variables with respect to different income groups. Ordinary least square method was used for the estimation of each equation for each variable. in the purpose of estimating this, different income groups were taken and identified the exact relationship between average incomes per household to the average expenditures per household since in the estimation of equations per capita consumption of each income group calculated respect to per capita income, so the formation of different equations were determined. Per capita income (PCY becomes independent of the unit of observation. Since, each household faces the same commodity prices prevailing at the time of household survey, for the purpose of analysis, total consumption expenditure has been disaggregated in to 11 commodity groups listed in table. The table indicates that value of R- squared is high and the co-efficient have correct signs and are significant at 1 percent level of significance, at 5 percent level of significance and at 10 percent level of significance. Overall results explain that with the increase in income expenditure increase for luxuries and decrease for necessities, but it will differ in rich and poor. Finally it is found that poor people consume more on necessities and rich people consume on luxuries as their income increase.

  3. Towards a Gendered Agro-Commodity Approach

    Directory of Open Access Journals (Sweden)

    Full Text Available Commodity or value chains are the dominant means to channel agro-food products from cultivators to consumers. Direct open markets are either non-existent or insignificant . These chains are also the main mechanisms for integrating underprivileged groups into the world economy. Why do global value chains generate sorrow for many and joy for a few, and why are these outcomes heavily gender biased? To look for answers this article critically reviews the post-2000 and earlier gender literature by proponents and opponents of the mainstream value chain approach. The purpose is to provide a methodological contribution on the integration of gender into the commodity chain approach. Most studies have fo cused on the economic effects of chain dynamics on women in agricultural product and labor markets. Some have extended this reasoning with social and cultural effects. Despite these advances, analytical gaps still exist as most existing research has concentrated on the agricultural nodes of modern, high value chains and lacks a gendered conceptual foundation. Scarce attention has been given to traditional staple crops, non-agricultural nodes, and feed back effects of gender relations on the chain. Our results indicate that an appropriate GCC approach should also consider the gendered impacts of the interaction between the governance structure and the institutiona l embeddedness, as well as the consequences of intra-household division of resources and labor in all stages of the chain. These two conceptual complements will be needed to explain the opportunities and constraints to improve gender equity in traditional and modern agro-commodity chains.

  4. Multiple commodities in statistical microeconomics: Model and market

    Baaquie, Belal E.; Yu, Miao; Du, Xin

    2016-11-01

    A statistical generalization of microeconomics has been made in Baaquie (2013). In Baaquie et al. (2015), the market behavior of single commodities was analyzed and it was shown that market data provides strong support for the statistical microeconomic description of commodity prices. The case of multiple commodities is studied and a parsimonious generalization of the single commodity model is made for the multiple commodities case. Market data shows that the generalization can accurately model the simultaneous correlation functions of up to four commodities. To accurately model five or more commodities, further terms have to be included in the model. This study shows that the statistical microeconomics approach is a comprehensive and complete formulation of microeconomics, and which is independent to the mainstream formulation of microeconomics.

    We study here numerically the behavior of an ideal gas like model of markets having only one non-consumable commodity. We investigate the behavior of the steady-state distributions of money, commodity and total wealth, as the dynamics of trading or exchange of money and commodity proceeds, with local (in time) fluctuations in the price of the commodity. These distributions are studied in markets with agents having uniform and random saving factors. The self-organizing features in money distribution are similar to the cases without any commodity (or with consumable commodities), the commodity distribution shows an exponential decay. The wealth distribution shows interesting behavior: Gamma like distribution for uniform saving propensity and has the same power-law tail, as that of the money distribution for a market with agents having random saving propensity.

  7. Phosphate: are we squandering a scarce commodity?

    Science.gov (United States)

    Ferro, Charles J; Ritz, Eberhard; Townend, Jonathan N

    2015-02-01

    Phosphorus is an essential element for life but is a rare element in the universe. On Earth, it occurs mostly in the form of phosphates that are widespread but predominantly at very low concentration. This relative rarity has resulted in a survival advantage, in evolutionary terms, to organisms that conserve phosphate. When phosphate is made available in excess it becomes a cause for disease, perhaps best recognized as a potential cardiovascular and renal risk factor. As a reaction to the emerging public health issue caused by phosphate additives to food items, there have been calls for a public education programme and regulation to bring about a reduction of phosphate additives to food. During the Paleoproterzoic era, an increase in the bioavailability of phosphate is thought to have contributed significantly to the oxygenation of our atmosphere and a dramatic increase in the evolution of new species. Currently, phosphate is used poorly and often wasted with phosphate fertilizers washing this scarce commodity into water bodies causing eutrophication and algal blooms. Ironically, this is leading to the extinction of hundreds of species. The unchecked exploitation of phosphate rock, which is an increasingly rare natural resource, and our dependence on it for agriculture may lead to a strange situation in which phosphate might become a commodity to be fought over whilst at the same time, health and environmental experts are likely to recommend reductions in its use.

  11. Voluntary medical male circumcision: logistics, commodities, and waste management requirements for scale-up of services.

    Directory of Open Access Journals (Sweden)

    2011-11-01

    Full Text Available BACKGROUND: The global HIV prevention community is implementing voluntary medical male circumcision (VMMC programs across eastern and southern Africa, with a goal of reaching 80% coverage in adult males by 2015. Successful implementation will depend on the accessibility of commodities essential for VMMC programming and the appropriate allocation of resources to support the VMMC supply chain. For this, the United States President's Emergency Plan for AIDS Relief, in collaboration with the World Health Organization and the Joint United Nations Programme on HIV/AIDS, has developed a standard list of commodities for VMMC programs. METHODS AND FINDINGS: This list of commodities was used to inform program planning for a 1-y program to circumcise 152,000 adult men in Swaziland. During this process, additional key commodities were identified, expanding the standard list to include commodities for waste management, HIV counseling and testing, and the treatment of sexually transmitted infections. The approximate costs for the procurement of commodities, management of a supply chain, and waste disposal, were determined for the VMMC program in Swaziland using current market prices of goods and services. Previous costing studies of VMMC programs did not capture supply chain costs, nor the full range of commodities needed for VMMC program implementation or waste management. Our calculations indicate that depending upon the volume of services provided, supply chain and waste management, including commodities and associated labor, contribute between US$58.92 and US$73.57 to the cost of performing one adult male circumcision in Swaziland. CONCLUSIONS: Experience with the VMMC program in Swaziland indicates that supply chain and waste management add approximately US$60 per circumcision, nearly doubling the total per procedure cost estimated previously; these additional costs are used to inform the estimate of per procedure costs modeled by Njeuhmeli et al. in

  12. Education: Commodity, Come-On, or Commitment?

    Science.gov (United States)

    Moore, John W.

    2000-07-01

    July 4, and the glass art shown on pages 812-816, remind us that freedom is fragile. Through their governments, citizens of democracies have traditionally made strong commitments to education on grounds that without it individuals would not be able to act responsibly and to make wise decisions in voting booths and public meetings. All citizens have a stake in everyone's education, because a better-educated citizenry benefits all of society. In this country such a commitment has produced a system of public schools and public universities that offers opportunities to many who otherwise could not afford a level of education commensurate with their talents. But there are signs that this commitment to public education is flagging. Many students, teachers, and administrators view education as merely a way to enhance personal prosperity. How often have you heard the statistic that a college education pays for itself through increased earning power, even if it costs $20,000-30,000 per year? Investing in education pays off just as investing in the stock market does, provided you wait long enough. Attending a better school gets you a better job and a better income. In other words, a certified level of education is a commodity-something that is useful and can be turned to commercial advantage. Viewing education as a commodity has several consequences. First, if education is a means to better employment rather than better citizenship, why should anyone pay for it other than the person who benefits? Why should I pay taxes to help someone else get a better job when I could be spending the money for my own benefit? Education as a commodity makes such attitudes reasonable, though not commendable, and the result is lessened support for public education. Second, those who supply education as an economic good should be rewarded, and those who are much better at educating should be rewarded much more. Hence the fear of Arthur Levine, president of Teachers College, Columbia University

  14. The relation between phosphine sorption and terminal gas concentrations in successful fumigation of food commodities.

    Reddy, Palvai Vanitha; Rajashekar, Yellappa; Begum, Khamrunissa; Leelaja, Bhadravathi Chandrappa; Rajendran, Somiahnadar

    2007-01-01

    Owing to increased tolerance and the development of resistance in stored product insects to the fumigant phosphine, in recent years there has been a shift in the target terminal concentration from 100 ppm (100 mL m(-3)) to a higher level of 1000 ppm to achieve 100% insect mortality in 7 day commodity treatments. Therefore, there is a need to investigate whether the revised target concentration could be achieved for food commodities fumigated with phosphine at the standard dose of 2 g m(-3) for 7 days under airtight conditions at > or = 25 degrees C. When different types of food commodity (total 74) were fumigated (300 g per replicate) with phosphine at 2 g m(-3) for 7 days, the terminal gas concentrations in the free space of the commodities varied from 0 to > 2000 ppm. In chambers containing no substrate, a 1417 ppm concentration was recorded. Paddy rice, most of the oilseeds, shelled tree nuts, butter beans, cardamom, green gram splits, coriander powder, rice bran and cocoa powder were more sorptive (> or =60%), such that the target concentration of 1000 ppm was not achieved at the end of 7 days. For these commodities, increased doses of 3-6 g m(-3) were required to attain 1000 ppm. In-shell almonds, green cardamom, in-shell peanuts, leaf tea, tamarind pulp and sunflower seeds were exceptionally sorptive (>90%), so that 0, 41, 112, 168, 203 and 217 ppm respectively were noted at the end of 7 days; the dose must exceed 6 g m(-3) for effective fumigation of these commodities.

  15. From creation to consumption: objects and commodities

    Directory of Open Access Journals (Sweden)

    Angélica Bautista López

    2008-11-01

    Full Text Available Objects, persons and ideas are all merely merchandise in a world that is highly industrialised and utterly superficial. Consumer societies produce a profusion of merchandise. In strictly economic terms, merchandise is whatever has an exchange-value, in  a world where objects are valued for their utility. So goods are whatever is useful, where use can be measured in monetary terms. This perspective impoverishes social relations. People relate only insofar as their value dictates, and that value is merely utilitarian. Moreover, this commercialisation reaches up to impoverish society as a whole. All this is the result of a long process of objectification which, seeing the world as the exchange of goods, ends up treating people just like any other tradable commodity. This article takes a critical look at the processes involved, and proposes an explanation in terms of the social construction of 'utility''.

    Commodity prices, especially oil prices, peaked in the aftermath of the financial crisis of 2007 and they have remained highly volatile. All things being equal, the increase in commodity prices may induce a similar tendency of inflation and hence become a monetary policy issue. However, the impact of the changes of commodity prices on inflation is not clear.

    2015-09-01

    High Dynamic Range (HDR) video provides a step change in viewing experience, for example the ability to clearly see the soccer ball when it is kicked from the shadow of the stadium into sunshine. To achieve the full potential of HDR video, so-called true HDR, it is crucial that all the dynamic range that was captured is delivered to the display device and tone mapping is confined only to the display. Furthermore, to ensure widespread uptake of HDR imaging, it should be low cost and available on commodity hardware. This paper describes an end-to-end HDR pipeline for capturing, encoding and streaming high-definition HDR video in real-time using off-the-shelf components. All the lighting that is captured by HDR-enabled consumer cameras is delivered via the pipeline to any display, including HDR displays and even mobile devices with minimum latency. The system thus provides an integrated HDR video pipeline that includes everything from capture to post-production, archival and storage, compression, transmission, and display.

    2014-07-01

    Commodity crop expansion, for both global and domestic urban markets, follows multiple land change pathways entailing direct and indirect deforestation, and results in various social and environmental impacts. Here we compare six published case studies of rapid commodity crop expansion within forested tropical regions. Across cases, between 1.7% and 89.5% of new commodity cropland was sourced from forestlands. Four main factors controlled pathways of commodity crop expansion: (i) the availability of suitable forestland, which is determined by forest area, agroecological or accessibility constraints, and land use policies, (ii) economic and technical characteristics of agricultural systems, (iii) differences in constraints and strategies between small-scale and large-scale actors, and (iv) variable costs and benefits of forest clearing. When remaining forests were unsuitable for agriculture and/or policies restricted forest encroachment, a larger share of commodity crop expansion occurred by conversion of existing agricultural lands, and land use displacement was smaller. Expansion strategies of large-scale actors emerge from context-specific balances between the search for suitable lands; transaction costs or conflicts associated with expanding into forests or other state-owned lands versus smallholder lands; net benefits of forest clearing; and greater access to infrastructure in already-cleared lands. We propose five hypotheses to be tested in further studies: (i) land availability mediates expansion pathways and the likelihood that land use is displaced to distant, rather than to local places; (ii) use of already-cleared lands is favored when commodity crops require access to infrastructure; (iii) in proportion to total agricultural expansion, large-scale actors generate more clearing of mature forests than smallholders; (iv) property rights and land tenure security influence the actors participating in commodity crop expansion, the form of land use displacement

  14. Modeling Multi-commodity Trade Information Exchange Methods

    2012-01-01

    Market mechanisms are entering into new fields of economy, in which some constraints of physical world, e.g. Kirchoffs Law in power grid, must be taken into account during trading. On such markets, some of commodities, like telecommunication bandwidth or electrical energy, appear to be non-storable, and must be exchanged in real-time. On the other hand, the markets tend to react at shortest possible time, so an idea to delegate some competency to autonomous software agents is very attractive. Multi-commodity mechanism addresses the aforementioned requirements. Modeling the relationships between the commodities allows to formulate new, more sophisticated models and mechanisms, which reflect decision situations in a better manner. Application of multi-commodity approach requires solving several issues related to data modeling, communication, semantics aspects of communication, reliability, etc. This book answers some of the questions and points out promising paths for implementation and development.

  15. Monetary policy and world commodity markets: 2000-2007

    Directory of Open Access Journals (Sweden)

    Hossein Askari

    2010-01-01

    Full Text Available Expansionary monetary policy in key industrial countries and a rapidly depreciating US dollar sent commodity prices soaring at unprecedented rates during 2003–2007. In contrast, consumer price indices in major OECD countries, a leading indicator for monetary policy, showed almost no inflation. This twin development is a puzzle as the evolution of consumer prices were not responsive to record low interest rates, doubledigit commodity inflation, and a sharp depreciation of the dollar. A common trend, identified as a monetary shock, drives commodity prices. Policymakers face a policy dilemma: maintain expansionary monetary policy stance with persistent commodity price inflation, subsequent severe world recession, and financial disorder, or tighten monetary policy with subsequent sustained economic growth and financial and price stability.

This paper considers some of those principles, their impact, and some perspectives on the potential and limits associated with green chemistry for commodity chemicals.

  19. Shadow Prices of Selected Agricultural Commodities – The Czech Case

    2016-10-01

    Full Text Available The main objective of the paper is to contribute to practical applicability of the CBA in the agricultural sector by exploring the chances to estimate Czech social values of selected agricultural commodities using available statistical data. More specifically, we try to analyse for which commodities secondary data sets are available from which we may deduce the estimates of shadow price ratios, then to estimate SPRs for selected agricultural commodities and to analyse and discuss the applicability of such estimates in practical appraisal with respect to theoretically ideal measures and resulting available measures as well as with respect to the situation in which the CBA analyst typically is. We selected the following commodities: poultry, pigs, bulls, milk, rapeseed, maize, barley and wheat as items more suitable for SPR estimates mostly because of the data availability and the internal homogeneity of the items, which was closer to the theoretically required values than for other commodities. Under additional simplifying assumptions, we estimated SPR proxies for the particular commodities and finally summarized the pros and cons for application of SPR alternatives.

  20. Portfolio Diversification with Commodities in Times of Financialization

    2015-03-01

    Full Text Available The study concentrates on the benefits of passive commodity investments in the context of the phenomenon of financialization. The research investigates the implications of increase in the correlation coefficients between equity and commodity investments for investors in financial markets. The paper is composed of several parts. First, the attributes of commodity investments and their benefits in the portfolio optimization are explored. Second, the phenomenon of the financialization is described and the research hypothesis is developed. Next, an empirical analysis is performed. I simulate the mean-variance spanning tests to examine the benefits of commodity investments before and after accounting for the impact of financialization. I proceed separate analysis for pre- and post-financialization period. The empirical research is based on asset classes’ returns and other related variables from years 1991-2012. The performed investigations indicate that the market financialization may have significant implications for commodity investors. Due to increase in correlation coefficients, the inclusion of the commodity futures in the traditional stock-bond portfolio appears to be no longer reasonable.

(doi:10.1016/j.physa.2013.05.008)), where the market price of every traded commodity, at each instant of time, is considered to be an independent random variable. The dynamics of commodity market prices is given by the unequal time correlation function and is modelled by the Feynman path integral based on an action functional. The correlation functions of the model are defined using the path integral. The existence of the action functional for commodity prices that was postulated to exist in Baaquie (Baaquie 2013 Phys. A 392, 4400-4416. (doi:10.1016/j.physa.2013.05.008)) has been empirically ascertained in Baaquie et al. (Baaquie et al. 2015 Phys. A 428, 19-37. (doi:10.1016/j.physa.2015.02.030)). The model's action functionals for different commodities has been empirically determined and calibrated using the unequal time correlation functions of the market commodity prices using a perturbation expansion (Baaquie et al. 2015 Phys. A 428, 19-37. (doi:10.1016/j.physa.2015.02.030)). Nine commodities drawn from the energy, metal and grain sectors are empirically studied and their auto-correlation for up to 300 days is described by the model to an accuracy of R(2)>0.90-using only six parameters.

  3. Budget Constraints Affect Male Rats' Choices between Differently Priced Commodities.

    Directory of Open Access Journals (Sweden)

    Marijn van Wingerden

    Full Text Available Demand theory can be applied to analyse how a human or animal consumer changes her selection of commodities within a certain budget in response to changes in price of those commodities. This change in consumption assessed over a range of prices is defined as demand elasticity. Previously, income-compensated and income-uncompensated price changes have been investigated using human and animal consumers, as demand theory predicts different elasticities for both conditions. However, in these studies, demand elasticity was only evaluated over the entirety of choices made from a budget. As compensating budgets changes the number of attainable commodities relative to uncompensated conditions, and thus the number of choices, it remained unclear whether budget compensation has a trivial effect on demand elasticity by simply sampling from a different total number of choices or has a direct effect on consumers' sequential choice structure. If the budget context independently changes choices between commodities over and above price effects, this should become apparent when demand elasticity is assessed over choice sets of any reasonable size that are matched in choice opportunities between budget conditions. To gain more detailed insight in the sequential choice dynamics underlying differences in demand elasticity between budget conditions, we trained N=8 rat consumers to spend a daily budget by making a number of nosepokes to obtain two liquid commodities under different price regimes, in sessions with and without budget compensation. We confirmed that demand elasticity for both commodities differed between compensated and uncompensated budget conditions, also when the number of choices considered was matched, and showed that these elasticity differences emerge early in the sessions. These differences in demand elasticity were driven by a higher choice rate and an increased reselection bias for the preferred commodity in compensated compared to

  4. World oil and agricultural commodity prices: Evidence from nonlinear causality

    The increasing co-movements between the world oil and agricultural commodity prices have renewed interest in determining price transmission from oil prices to those of agricultural commodities. This study extends the literature on the oil-agricultural commodity prices nexus, which particularly concentrates on nonlinear causal relationships between the world oil and three key agricultural commodity prices (corn, soybeans, and wheat). To this end, the linear causality approach of Toda-Yamamoto and the nonparametric causality method of Diks-Panchenko are applied to the weekly data spanning from 1994 to 2010. The linear causality analysis indicates that the oil prices and the agricultural commodity prices do not influence each other, which supports evidence on the neutrality hypothesis. In contrast, the nonlinear causality analysis shows that: (i) there are nonlinear feedbacks between the oil and the agricultural prices, and (ii) there is a persistent unidirectional nonlinear causality running from the oil prices to the corn and to the soybeans prices. The findings from the nonlinear causality analysis therefore provide clues for better understanding the recent dynamics of the agricultural commodity prices and some policy implications for policy makers, farmers, and global investors. This study also suggests the directions for future studies. - Research highlights: {yields} This study determines the price transmission mechanisms between the world oil and three key agricultural commodity prices (corn, soybeans, and wheat). {yields} The linear and nonlinear cointegration and causality methods are carried out. {yields} The linear causality analysis supports evidence on the neutrality hypothesis. {yields} The nonlinear causality analysis shows that there is a persistent unidirectional causality from the oil prices to the corn and to the soybeans prices.

    2016-06-01

    Full Text Available Agricultural product is commodity which tends to fluctuate. Price volatility is caused by the change of agricultural production due to climate change as well as pest and disease. Furthermore, it is also caused by the change of agricultural land and high demand of agricultural products on religious holidays. This study was conducted to examine how volatile some of main food commodities in Banyumas Regency. Secondary data analysis method with quantitative approach was used in this research. Time series data of some food commodity prices (rice IR 64, local soybean, maize, chili red peppers, onion and garlic from January 2008 – December 2013 were utilized. The coefficient of variation was calculated to determine price volatility. The result showed that the price of red chili pepper, onion and garlic was tending to volatile. The coefficient of variation ratio of those commodities was about 20% - 35%. While the price of rice, local soybean and maize was stable. The coefficient of variation ratio of those commodities was less than 9%. This study also includes some policies that can be suggested to prevent price volatility.

    Trading of aquatic animals and aquatic animal products has become increasingly globalized during the last couple of decades. This commodity trade has increased the risk for the spread of aquatic animal pathogens. The World Organisation for Animal Health (OIE) is recognized as the international standard-setting organization for measures relating to international trade in animals and animal products. In this role, OIE has developed the Aquatic Animal Health Code, which provides health measures to be used by competent authorities of importing and exporting countries to avoid the transfer of agents pathogenic for animals or humans, whilst avoiding unjustified sanitary barriers. An OIE ad hoc group developed criteria for assessing the safety of aquatic animals or aquatic animal products for any purpose from a country, zone or compartment not declared free from a given disease 'X'. The criteria were based on the absence of the pathogenic agent in the traded commodity or inactivation of the pathogenic agent by the commercial processing used to produce the commodity. The group also developed criteria to assess the safety of aquatic animals or aquatic animal products for retail trade for human consumption from potentially infected areas. Such commodities were assessed considering the form and presentation of the product, the expected volume of waste tissues generated by the consumer and the likely presence of viable pathogenic agent in the waste. The ad hoc group applied the criteria to commodities listed in the individual disease chapters of the Aquatic Animal Health Code (2008 edition). Revised lists of commodities for which no additional measures should be required by the importing countries regardless of the status for disease X of the exporting country were developed and adopted by the OIE World Assembly of Delegates in May 2011. The rationale of the criteria and their application will be explained and demonstrated using examples.

    1998-01-01

    The NAS Systems Division has recently embarked on a significant new way of handling the mass storage problem. One of the basic goals of this new development are to build systems at very large capacity and high performance, yet have the advantages of commodity products. The central design philosophy is to build storage systems the way the Internet was built. Competitive, survivable, expandable, and wide open. The thrust of this paper is to describe the motivation for this effort, what we mean by commodity mass storage, what the implications are for a facility that performs such an action, and where we think it will lead.

The information is then entered onto computer manually, thus making the process a long and arduous one. With the development of the Haiti Commodity Tracker mobile app, we are able to make this commodity price data recording process more efficient. Officials may use this information for making inferences about the difference in commodity prices and for food distribution during critical time after natural disasters. This information can also be utilized by governments and aid agencies on their food assistance programs. Agronomists record the item prices from several sample sites in a marketplace and compare those results from other markets across the region. Due to limited connectivity in rural areas, data is first saved to the phone's database and then retransmitted to a central server via SMS messaging. The mobile app is currently being field tested by an international NGO providing agricultural aid and support in rural Haiti.

In this section, academics, policy makers and practitioners engage in a dialogue on global development challenges. Papers are copy-edited but not peer-reviewed. Instead, an initial thematic contribution is followed by critical comments and reactions from different stakeholders. This paper by Werner Thut is followed by reactions and analysis from a non-profit policy institute (Alexandra Gillies, Revenue Watch Institute, New York, ‘Crafting a Strategic Response to the Commodity-Development Conundrum’, a Southern scholar (Prof. Humberto Campodonico, Universidad Nacional Mayor de San Marcos, Lima ‘Going Beyond Transparency and Good Governance’ | ‘Más allá de la transparencia y una buena gobernanza’ and a representative of the trading sector (Stéphane Graber, Secretary General of Geneva Trading & Shipping Association – ‘Reassessing the Merchants’ Role in a Globalized Economy’.PAPER’S ABSTRACTSwitzerland is one of the world’s largest commodity trading hub. The author, senior policy adviser at the Swiss Agency for Development and Cooperation (SDC, reviews experiences and policy options related to commodity trading from a development policy perspective. While this sector has become of strategic importance to Switzerland’s economy, it also entails a number of risks. On the other hand, Swiss development cooperation efforts focus on several resource-rich countries, whose mineral and agricultural commodities are traded via Switzerland. How can Switzerland assist these countries to reap the benefits of their natural resource wealth? This paper looks at development policy aspects of commodity trading in relation to Swiss foreign and domestic policy. It examines ongoing policy debates in Switzerland and discusses development policy options.

  9. Implications of Climate Volatility for Agricultural Commodity Markets in the Presence of Biofuel Mandates

    Science.gov (United States)

    Verma, M.; Diffenbaugh, N. S.; Hertel, T. W.; Beckman, J.

    2011-12-01

    In presence of bio-fuels, link between energy and agricultural commodity markets has become more complex. An increase in ethanol production to minimum 15bn gallons a year - Renewable Fuel Standard (RFS) and current technically permissible maximum 10% blending limit - Blend Wall (BW); make the link even stronger. If oil prices in future do not rise significantly from their current levels, this minimum production requirement would likely be binding. In such a scenario any fluctuation in crop production will have to be absorbed by the non-ethanol usage of the crop and would translate into crop prices adjusting to clear the markets and therefore the commodity prices will be more volatile. At high oil prices it is possible that the BW may become binding, severing the link between oil prices and commodity prices as well, potentially leading to higher price volatility. Hertel and Beckman (2010) find that, with both RFS and BW simultaneously binding, corn price volatility due to supply side shocks (which could arise from extreme climate events) could be more than 50% as large as in the absence of bio-fuel policies. So energy markets are important determinants of agricultural commodity price volatility. This proposal intends to introduce the increased supply side volatility on account of climate change and volatility, in the framework. Global warming on account of increased GHG concentrations is expected to increase the intensity and frequency of hot extremes in US (Diffenbaugh et al. 2008) and therefore affect corn yields. With supply shocks expected to increase, binding RFS and BW will exacerbate the volatility, while if they are non-binding then the price changes could be cushioned. We propose to model the impacts of climate changes and volatility on commodity prices by linking three main components - a. Projections for change in temperature and precipitation using climate model b. A statistical model to predict impacts of change in climate variable on corn yields in US

  10. HESTIA Commodities Exchange Pallet and Sounding Rocket Test Stand

    Science.gov (United States)

    Chaparro, Javier

    2013-01-01

    During my Spring 2016 internship, my two major contributions were the design of the Commodities Exchange Pallet and the design of a test stand for a 100 pounds-thrust sounding rocket. The Commodities Exchange Pallet is a prototype developed for the Human Exploration Spacecraft Testbed for Integration and Advancement (HESTIA) program. Under the HESTIA initiative the Commodities Exchange Pallet was developed as a method for demonstrating multi-system integration thru the transportation of In-Situ Resource Utilization produced oxygen and water to a human habitat. Ultimately, this prototype's performance will allow for future evaluation of integration, which may lead to the development of a flight capable pallet for future deep-space exploration missions. For HESTIA, my main task was to design the Commodities Exchange Pallet system to be used for completing an integration demonstration. Under the guidance of my mentor, I designed, both, the structural frame and fluid delivery system for the commodities pallet. The fluid delivery system includes a liquid-oxygen to gaseous-oxygen system, a water delivery system, and a carbon-dioxide compressors system. The structural frame is designed to meet safety and transportation requirements, as well as the ability to interface with the ER division's Portable Utility Pallet. The commodities pallet structure also includes independent instrumentation oxygen/water panels for operation and system monitoring. My major accomplishments for the commodities exchange pallet were the completion of the fluid delivery systems and the structural frame designs. In addition, parts selection was completed in order to expedite construction of the prototype, scheduled to begin in May of 2016. Once the commodities pallet is assembled and tested it is expected to complete a fully integrated transfer demonstration with the ISRU unit and the Environmental Control and Life Support System test chamber in September of 2016.

  12. Private Governance, Hegemonic Struggles, and Institutional Outcomes in the Transnational Cotton Commodity Chain

    Directory of Open Access Journals (Sweden)

    Amy Quark

    2015-08-01

    Full Text Available Transnational firms have rolled out new forms of private governance at the same time as the rise of new economic powerhouses like China has fomented growing inter-state tensions. This points to critical questions: how does inter-state competition shape private governance of transnational commodity chains and how does private governance shape inter-state rivalries? I explore these questions by tracing the construction and dissolution of sectoral hegemonic coalitions that govern commodity chains. Drawing on the case of cotton quality governance from 2000-2012, I argue that a coalition of the U.S. state and transnational merchants has reconstituted its sectoral hegemony to allow expanded accumulation and accommodate their main rival~China. The U.S. state created standards with Chinese characteristics, while transnational merchants made the authority structure of their institutions more inclusive. However, this reconstituted hegemony remains unstable. Facing continued regulatory competition from China, the U.S. state has constructed new forms of meta-governance that could facilitate a shift to Chinese-led sectoral hegemony but under U.S. oversight. Moreover, these sectoral hegemonic struggles compelled Western transnational merchants to fracture their long-standing relationship with the U.S. state in the hegemonic coalition in order to position their private institutions as geopolitically neutral and thus compatible with the hegemonic leadership of either the U.S. or Chinese states in the sector. By tracing struggles among coalitions of leading firms and states for hegemony over the institutions governing particular commodity chain sectors, we can shed light on possible trajectories within broader world-system level hegemonic struggles that at once constitute and are constituted by these sectoral dynamics.

  13. The Role of Incompleteness in Commodity Futures Markets

    Directory of Open Access Journals (Sweden)

    Takashi eKanamura

    2015-10-01

    Full Text Available This paper proposes a convenience yield-based pricing for commodity futures, which embeds incompleteness of commodity futures markets in convenience yields. By using the pricing method, we conduct empirical analyses of the prices of WTI crude oil, heating oil, and natural gas futures traded on the NYMEX in order to assess the incompleteness of energy futures markets. We show that the fluctuation from the incompleteness is partly driven by the fluctuation from convenience yields. In addition, it is shown that the incompleteness of natural gas futures market is more highlighted than the incompleteness of WTI crude oil and heating oil futures markets. We apply the implied market price of risk from the NYMEX data to pricing an Asian call option written on WTI crude oil futures. Finally, we try to apply the market incompleteness analysis to the post-crisis periods after 2009.

    At present food irradiation is considered an effective, broad-spectrum, residue-free, mature technology. Expertise in irradiation processing exists in a network of centers around the world, some of them in developing countries like Brazil and Argentina South American region. The use of renewable resources coming from crops products is becoming attractive also for non-food applications. In this sense, a complete new approach of higher aggregated value of some commodities like soy and maize, for example, is as renewable resources to create functional polymers, mainly for innovative biodegradable packaging solutions. There is a need of innovative approaches to produce edible/biodegradable materials from natural polymeric macromolecules with adequate properties. Incipient researches pointed to the successful use of irradiation processing to obtain or modify different types of biodegradable/edible plastic materials. This new radiation technology application is particularly important for countries that are leading producers of soybean and other commodities. (Author)

    Understanding and measuring the relative roles of different causal channels between commodity prices and exchange rates has important implications in financial decision making, especially for market participants with short horizons. From a macroeconomic perspective, this can also be useful for interpreting exchange rate movements, financial market monitoring and monetary policy. Basic economic reasoning on currency demand suggests that the currencies of countries whose exports depend heavily ...

    IntroductionThe U.S. Geological Survey, National Minerals Information Center, analyzes mineral and metal supply chains by identifying and describing major components of mineral and material flows from ore extraction, through intermediate forms, to a final product. This report focuses on an important component of the world’s supply chain: the amounts and global distribution of major consumer, producer, and exchange stocks of selected mineral commodities. In this report, the term “stock” is used instead of “inventory” and refers to accumulations of mined ore, intermediate products, and refined mineral-based commodities that are in a form that meets the agreed-upon specifications of a buyer or processor of intermediate products. These may include certain ores such as bauxite, concentrates, smelter products, and refined metals. Materials sometimes referred to as inventory for accounting purposes, such as ore contained in a deposit or in a leach pile, or materials that need to be further processed before they can be shipped to a consumer, are not considered. Stocks may be held (owned) by consumers, governments, investors, producers, and traders. They may serve as (1) a means to achieve economic, social, and strategic goals through government policies; (2) a secure source of supply to meet demand and to mitigate potential shortages in the supply chain; (3) a hedge to mitigate price volatility; and (4) vehicles for speculative investment.The paucity and uneven reliability of data for stocks of ores and concentrates and for material held by producers, consumers, and merchants hinder the accurate estimating of the size and distribution of this portion of the supply chain for certain commodities. This paper reviews the more visible stocks held in commodity exchange warehouses distributed throughout the world.

  3. Network structure impacts global commodity trade growth and resilience

    2017-01-01

    Global commodity trade networks are critical to our collective sustainable development. Their increasing interconnectedness pose two practical questions: (i) Do the current network configurations support their further growth? (ii) How resilient are these networks to economic shocks? We analyze the data of global commodity trade flows from 1996 to 2012 to evaluate the relationship between structural properties of the global commodity trade networks and (a) their dynamic growth, as well as (b) the resilience of their growth with respect to the 2009 global economic shock. Specifically, we explore the role of network efficiency and redundancy using the information theory-based network flow analysis. We find that, while network efficiency is positively correlated with growth, highly efficient systems appear to be less resilient, losing more and gaining less growth following an economic shock. While all examined networks are rather redundant, we find that network redundancy does not hinder their growth. Moreover, systems exhibiting higher levels of redundancy lose less and gain more growth following an economic shock. We suggest that a strategy to support making global trade networks more efficient via, e.g., preferential trade agreements and higher specialization, can promote their further growth; while a strategy to increase the global trade networks’ redundancy via e.g., more abundant free-trade agreements, can improve their resilience to global economic shocks.

    The global population currently stands at approximately 7 billion and is expected to increase to between 8.3 and 10.9 billion by 2050. To put this into perspective, today's global population is triple what it was in 1950. Commodities are required for healthy societies, for robust economies and to raise living standards in the developing world. With major increases the population particularly in nations with emerging economies, the demand for commodities such as water, energy and minerals will significantly increase during the next several decades. Among the concerns are clean and available freshwater, expanded energy sources from natural gas and nuclear to renewable energy, and emerging needs for specialty materials that are needed for advanced technology to expanded use of more conventional minerals for agriculture and commerce. The developing world may have the greatest need for these commodities and also be the source of many of them. At the conclusion of the International Year of Planet Earth, a small group was formed to assess the need for a major scientific effort in the geosciences. Under the auspices of the International Union of Geological Sciences (IUGS), the strategic initiatives group met and a broad initiative entitled 'Resourcing Future Generations' (RFG) that was designed to implement a scientific strategy to address the increasing demand for commodities over the next 25 years. The initiative focused on water resources, energy and minerals. The group felt strongly that the minerals component should be the initial emphasis and hoped that other global scientific organizations like IUGS would embrace the water and energy themes. Since this initial effort a number of workshops and presentations have been made including China, the International Geological Congress in Brisbane, the Davos Summit, Berlin, and Namibia amongst others. The strategic initiative planning group identifies 4 challenges to meeting future global mineral needs which are improved

    Introduction Logistics management information system for health commodities remained poorly implemented in most of developing countries. To assess the status of laboratory logistics management information system for HIV/AIDS and tuberculosis laboratory commodities in public health facilities in Addis Ababa. Methods A cross-sectional descriptive study was conducted from September 2010-January 2011 at selected public health facilities. A stratified random sampling method was used to include a total of 43 facilities which, were investigated through quantitative methods using structured questionnaires interviews. Focus group discussion with the designated supply chain managers and key informant interviews were conducted for the qualitative method. Results There exists a well-designed logistics system for laboratory commodities with trained pharmacy personnel, distributed standard LMIS formats and established inventory control procedures. However, majority of laboratory professionals were not trained in LMIS. Majority of the facilities (60.5%) were stocked out for at least one ART monitoring and TB laboratory reagents and the highest stock out rate was for chemistry reagents. Expired ART monitoring laboratory commodities were found in 25 (73.5%) of facilities. Fifty percent (50%) of the assessed hospitals and 54% of health centers were currently using stock/bin cards for all HIV/AIDS and TB laboratory commodities in main pharmacy store, among these only 25% and 20.8% of them were updated with accurate information matching with the physical count done at the time of visit for hospitals and health centers respectively. Conclusion Even though there exists a well designed laboratory LMIS, keeping quality stock/bin cards and LMIS reports were very low. Key ART monitoring laboratory commodities were stock out at many facilities at the day of visit and during the past six months. Based on findings, training of laboratory personnel's managing laboratory commodities and keeping

    Visualization of protein structures using stereoscopic systems is frequently needed by structural biologists working to understand a protein's structure-function relationships. Often several scientists are working as a team and need simultaneous interaction with each other and the graphics representations. Most existing molecular visualization tools support single-user tasks, which are not suitable for a collaborative group. Expensive caves, domes or geowalls have been developed, but the availability and low cost of high-definition televisions (HDTVs) and game controllers in the commodity entertainment market provide an economically attractive option to achieve a collaborative environment. This paper describes a low-cost environment, using standard consumer game controllers and commercially available stereoscopic HDTV monitors with appropriate signal converters for structural biology collaborations employing existing binary distributions of commonly used software packages like Coot, PyMOL, Chimera, VMD, O, Olex2 and others.

    We describe a new 512-CPU Beowulf cluster with Teraflop performance dedicated to problems in computational astrophysics. The cluster incorporates a cubic network topology based on inexpensive commodity 24-port gigabit switches and point to point connections through the second gigabit port on each Linux server. This configuration has network performance competitive with more expensive cluster configurations and is scaleable to much larger systems using other network topologies. Networking represents only about 9% of our total system cost of USD$561K. The standard Top 500 HPL Linpack benchmark rating is 1.202 Teraflops on 512 CPUs so computing costs by this measure are $0.47/Megaflop. We also describe 4 different astrophysical applications using complex parallel algorithms for studying large-scale structure formation, galaxy dynamics, magnetohydrodynamic flows onto blackholes and planet formation currently running on the cluster and achieving high parallel performance.

In this regard, especially updated become theoretical developments in the field of commodity flows on an international caliber. The article analyzes the interpretations of scholars of various economic scientists of the concept of "commodity flow" explores theoretical approaches for building goods distribution management at the level of international companies. Particular attention is paid to the risks assessment in the process of changing the output of trading companies at the international level. The role of the international net brokers is determining in the logistic system of goods distribution. The front most methods of risk management of major trade companies are highly investigating. The authors conclude that in entering the international markets trading companies are often unable to develop an effective risk management system due to lack of information, difficulty adapting to the new business environment. Many aspects of international goods distribution require further study with the aim of improving the efficiency of inventory management and logistics network trade flows of businesses

  1. Commodity clusters: Performance comparison between PC`s and workstations

    Energy Technology Data Exchange (ETDEWEB)

    Carter, R.; Laroco, J.; Armstrong, R.

    1996-03-01

    Workstation clusters were originally developed as a way to leverage the better cost basis of UNIX workstations to perform computations previously handled only by relatively more expensive supercomputers. Commodity workstation clusters take this evolutionary process one step further by replacing equivalent proprietary workstation functionality with less expensive PC technology. As PC technology encroaches on proprietary UNIX workstation vendor markets, these vendors will see a declining share of the overall market. As technology advances continue, the ability to upgrade a workstations performance plays a large role in cost analysis. For example, a major upgrade to a typical UNIX workstation means replacing the whole machine. As major revisions to the UNIX vendor`s product line come out, brand new systems are introduced. IBM compatibles, however, are modular by design, and nothing need to be replaced except the components that are truly improved. The DAISy cluster, for example, is about to undergo a major upgrade from 90MHz Pentiums to 200MHz Pentium Pros. All of the memory -- the system`s largest expense -- and disks, power supply, etc., can be reused. As a result, commodity workstation clusters ought to gain an increasingly large share of the distributed computing market.

  2. Balancing Acts: Culture as Commodity Among Business Consultants

    2013-09-01

    Full Text Available In this article the authors intend to analyze how the concept of culture is packaged, sold and delivered as a commodity. It is based on an ethnographic study of a Swedish consultancy in the field of cross-cultural communication and the relationship between the company and its clients. The clients were primarily foreign executives working in Sweden or Swedish expatriates, preparing for life abroad. The significance of culture-as-commodity will be explored from the perspective of the company as well as its clients in order to shed light on how the concept of culture can be communicated and what happens to it in the process. The study shows how the company combines theoretical perspectives from anthropology and intercultural communication with the aim to deliver a complex yet accessible understanding of culture to its clients. The analysis shows that these perspectives both clash and synergize, creating contradictions as well as turning culture into an accessible and useful tool for clients. The authors argue that researchers in the field of applied cultural analysis can learn from the example put forth by the balancing act between these two perspectives on culture performed by the company. The authors conclude that although the commodification process reduces and simplifies the meaning(s of culture, the company still manages to put culture on the agenda, demonstrating to its clients how, why, and in what ways it matters to them.

    2008-02-01

    The current high prices for petroleum and natural gas have spurred the chemical industry to examine alternative feedstocks for the production of commodity chemicals. High feedstock prices have driven methanol and ammonia production offshore. The U.S. Chemical Industry is the largest user of natural gas in the country. Over the last 30 years, alternatives to conventional petroleum and natural gas feedstocks have been developed, but have limited, if any, commercial implementation in the United States. Alternative feedstocks under consideration include coal from unconventional processing technologies, such as gasification and liquefaction, novel resources such as biomass, stranded natural gas from unconventional reserves, and heavy oil from tar sands or oil shale. These feedstock sources have been evaluated with respect to the feasibility and readiness for production of the highest volume commodity chemicals in the United States. Sources of organic compounds, such as ethanol from sugar fermentation and bitumen-derived heavy crude are now being primarily exploited for fuels, rather than for chemical feedstocks. Overall, government-sponsored research into the use of alternatives to petroleum feedstocks focuses on use for power and transportation fuels rather than for chemical feedstocks. Research is needed to reduce cost and technical risk. Use of alternative feedstocks is more common outside the United States R&D efforts are needed to make these processes more efficient and less risky before becoming more common domestically. The status of alternative feedstock technology is summarized.

    Over the last several decades, voluntary certification programs have become a key approach to promote sustainable supply chains for agricultural commodities. These programs provide premiums and other benefits to producers for adhering to environmental and labor practices established by the certifying entities. Following the principles of Cochrane Reviews used in health sciences, we assess evidence to evaluate whether voluntary certification of tropical agricultural commodities (bananas, cocoa, coffee, oil palm, and tea) has achieved environmental benefits and improved economic and social outcomes for small-scale producers at the level of the farm household. We reviewed over 2600 papers in the peer-review literature and identified 24 cases of unique combinations of study area, certification program, and commodity in 16 papers that rigorously analyzed differences between treatment (certified households) and control groups (uncertified households) for a wide range of response variables. Based on analysis of 347 response variables reported in these papers, we conclude that certification is associated on average with positive outcomes for 34% of response variables, no significant difference for 58% of variables, and negative outcomes for 8% of variables. No significant differences were observed for different categories of responses (environmental, economic and social) or for different commodities (banana, coffee and tea), except negative outcomes were significantly less for environmental than other outcome categories (p = 0.01). Most cases (20 out of 24) investigated coffee certification and response variables were inconsistent across cases, indicating the paucity of studies to conduct a conclusive meta-analysis. The somewhat positive results indicate that voluntary certification programs can sometimes play a role in meeting sustainable development goals and do not support the view that such programs are merely greenwashing. However, results also indicate that

    Full Text Available BACKGROUND: Understanding the sources of contraceptive commodities is an important aspect of the delivery of family planning services and is required by planning programme managers for strategic planning purposes. Findings from the 2003 Nigeria Demographic and Health Survey have previously showed that the private sector was the most frequently reported source of contraceptive supply, providing contraception to two and a half times as many women as the public sector. We conducted a community-based study to examine further the sources of contraceptive commodity for users in Nigeria with a view to identifying their preferences for distribution centres. This information would be useful to improve commodity distribution and to build the necessary capacity for satisfactory delivery of contraceptives. METHODS AND FINDINGS: A multi-stage random sampling technique was used. A state was randomly selected to represent each of the four health zones in Nigeria. Two local government areas (LGAs were then selected representing both urban and rural areas. Ten enumeration areas were subsequently selected from each LGA. Of the 2,001 respondents aged 15-49 years, 1,647 (82.3% were sexually active, out of which 244 were found to be using contraceptive methods at the time of the study, giving a contraceptive prevalence of 14.8%. The commonest source of information on contraceptives was through friends (34%, followed by the radio (11.5% and husbands (10.2%. Most respondents procured their contraceptives from chemist/patent medicine shops (19.7%, while only 0.8% obtained them from designated family planning clinics. The younger groups in this study (15-24 years, single people, Catholics, and Muslims, showed a greater preference for chemist/patent medicine shops for their sources of contraceptives. The older groups and married respondents, however, made use of government and private hospitals to obtain their contraceptives. CONCLUSION: Strategies to increase

  8. Optimal commodity taxes for Brazil based on AIDS preferences

    Full Text Available In this study we calculate optimal commodity taxes for Brazil. Simulations are based on the Almost Ideal Demand System , estimated using Brazilian household data. The trade off between equity and efficiency is taken into account by introducing a government aversion to inequality parameter into a social welfare function, which is maximized subject to a balanced government budget requirement. Our results show that the optimal commodity tax structure is characterized by selective tax rates when the only tax policy instrument available is commodity taxation. We extend the analysis by allowing for a uniform poll payment to be made by the government. In this case tax rates are regressive and poll transfer levels are unreasonably high. When we cap transfers with a binding ceiling the former pattern is restored. Comparing with Siqueira (1998, we have also observed a relative robustness of optimal tax rates to household preferences forms.O presente estudo tem como objetivo calcular a estrutura ótima da tributação sobre o consumo no Brasil. As simulações baseiam-se no sistema de demanda Almost Ideal Demand System estimados com dados da POF/IBGE. O trade off entre eqüidade e eficiência é incorporado no modelo com a introdução de um coeficiente de aversão à desigualdade social na função de bem-estar social, sujeita à restrição de receita do governo. Além da hipótese de que o único instrumento de política tributária disponível seja a tributação sobre o consumo, nosso modelo também admite a concessão de uma transferência uniforme lump sum de renda per capita do governo para todos os agentes econômicos. Os resultados mostram que a estrutura tributária sobre o consumo caracteriza-se pela seletividade das alíquotas, que se torna mais significativa para valores altos do parâmetro de aversão à desigualdade. Este resultado é revertido para uma estrutura tributária regressiva com a introdução de uma transferência uniforme lump

    We investigate multifractal properties of commodity time series using multifractal detrended fluctuation analysis (MF-DFA). We find that agricultural and energy-related commodities exhibit very similar behavior, while the multifractal behavior of daily and monthly commodity series is rather different. Daily series demonstrate overall uncorrelated behavior, lower degree of multifractality and the dominance of small fluctuations. On the other hand, monthly commodity series show overall persistent behavior, higher degree of multifractality and the dominance of large fluctuations. After shuffling the series, we find that the multifractality is due to a broad probability density function for daily commodities series, while for monthly commodities series multifractality is caused by both a broad probability density function and long term correlations.

Taking such a perspective may be helpful in thinking about why transitioning to more sustainable strategic orientations is challenging even in the presence of financial incentives to make...... such changes. In assessing the transition to organic production and marketing in a commodity agriculture context we find that contending ideologies restrict its adoption.

    2015-06-01

    Through metabolic engineering cyanobacteria can be employed in biotechnology. Combining the capacity for oxygenic photosynthesis and carbon fixation with an engineered metabolic pathway allows carbon-based product formation from CO(2), light, and water directly. Such cyanobacterial 'cell factories' are constructed to produce biofuels, bioplastics, and commodity chemicals. Efforts of metabolic engineers and synthetic biologists allow the modification of the intermediary metabolism at various branching points, expanding the product range. The new biosynthesis routes 'tap' the metabolism ever more efficiently, particularly through the engineering of driving forces and utilization of cofactors generated during the light reactions of photosynthesis, resulting in higher product titers. High rates of carbon rechanneling ultimately allow an almost-complete allocation of fixed carbon to product above biomass.

    The human capacity for altering the water cycle has been well documented and given the expected change due to population, income growth, biofuels, climate, and associated land use change, there remains great uncertainty in both the degree of increased pressure on land and water resources and in our ability to adapt to these changes. Alleviating regional shortages in water supply can be carried out in a spatial hierarchy through i) direct trade of water between all regions, ii) development of infrastructure to improve water availability within regions (e.g. impounding rivers), iii) via inter-basin hydrological transfer between neighboring regions and, iv) via virtual water trade. These adaptation strategies can be managed via market trade in water and commodities to identify those strategies most likely to be adopted. This work combines the physically-based University of New Hampshire Water Balance Model (WBM) with the macro-scale Purdue University Simplified International Model of agricultural Prices Land use and the Environment (SIMPLE) to explore the interaction of supply and demand for fresh water globally. In this work we use a newly developed grid cell-based version of SIMPLE to achieve a more direct connection between the two modeling paradigms of physically-based models with optimization-driven approaches characteristic of economic models. We explore questions related to the global and regional impact of water scarcity and water surplus on the ability of regions to adapt to future change. Allowing for a variety of adaptation strategies such as direct trade of water and expanding the built water infrastructure, as well as indirect trade in commodities, will reduce overall global water stress and, in some regions, significantly reduce their vulnerability to these future changes.

    Increasing fossil fuel prices, energy security considerations and environmental concerns, particularly concerning climate change, have motivated countries to explore alternative energy sources including biofuels. Global demand for biofuels has been rising rapidly due to biofuel support policies established in many countries. However, proposed strong links between biofuels demand and recent years' high food commodity prices, and notions that increasing biofuels production might bring about serious negative environmental impacts, in particularly associated with the land use change to biofuel crops, have shifted public enthusiasm about biofuels. In this context, the ELOBIO project aims at shedding further light to these aspects of biofuel expansion by collecting and reviewing the available data, and also developing strategies to decrease negative effects of biofuels while enabling their positive contribution to climate change, security of supply and rural development. ELOBIO considers aspects associated with both 1st and 2nd generation biofuels, hence analyses effects on both agricultural commodity markets and lignocellulosic markets. This project, funded by the Intelligent Energy Europe programme, consists of a review of current experiences with biofuels and other renewable energy policies and their impacts on other markets, iterative stakeholder-supported development of low-disturbing biofuels policies, model supported assessment of these policies' impacts on food, feed and lignocellulosic markets, and finally an assessment of the effects of selected optimal policies on biofuels costs and potentials. Results of the ELOBIO study show that rapid biofuel deployment without careful monitoring of consequences and implementation of mitigating measures risks leading to negative consequences. Implementing ambitious global biofuel targets for 2020, based on current 1st generation technologies, can push international agricultural commodity prices upwards and

  19. A Review on Biomass Densification Systems to Develop Uniform Feedstock Commodities for Bioenergy Application

    Energy Technology Data Exchange (ETDEWEB)

    2011-11-01

    Developing uniformly formatted, densified feedstock from lignocellulosic biomass is of interest to achieve consistent physical properties like size and shape, bulk and unit density, and durability, which significantly influence storage, transportation and handling characteristics, and, by extension, feedstock cost and quality. A variety of densification systems are considered for producing a uniform format feedstock commodity for bioenergy applications, including (a) baler, (b) pellet mill, (c) cuber, (d) screw extruder, (e) briquette press, (f) roller press, (g) tablet press, and (g) agglomerator. Each of these systems has varying impacts on feedstock chemical and physical properties, and energy consumption. This review discusses the suitability of these densification systems for biomass feedstocks and the impact these systems have on specific energy consumption and end product quality. For example, a briquette press is more flexible in terms of feedstock variables where higher moisture content and larger particles are acceptable for making good quality briquettes; or among different densification systems, a screw press consumes the most energy because it not only compresses but also shears and mixes the material. Pretreatment options like preheating, grinding, steam explosion, torrefaction, and ammonia fiber explosion (AFEX) can also help to reduce specific energy consumption during densification and improve binding characteristics. Binding behavior can also be improved by adding natural binders, such as proteins, or commercial binders, such as lignosulphonates. The quality of the densified biomass for both domestic and international markets is evaluated using PFI (United States Standard) or CEN (European Standard).

    Directory of Open Access Journals (Sweden)

    David B. Nieborg

    2015-12-01

    Full Text Available The goal of this article is to add a complementary perspective to the study of social network sites by surveying how the political economy of social media platforms relates to the structure of free-to-play games in their commodity form. Drawing on the theory of multisided markets and critical political economy, this article surveys the political economy of game apps and investigates how it is symbiotically related to the technological and economic logic underlying connective platforms operated by Google, Apple, Facebook, and Amazon. These social media platforms operate app stores that sustain the transformation of games as fixed, physically distributed products that follow a transaction logic, into digitally distributed, freely accessible, or “free-to-play” apps. Through a case study of the popular casual game Candy Crush Saga it is contended that the connective properties of social media platforms affect the form and format of game apps as cultural commodities. Candy Crush Saga developer King Digital Entertainment has been able to attract hundreds of millions of players and build a business model that combines the commodification of virtual items, connectivity, user attention, user data, and play. It is argued that the free-to-play commodity form comprises three commodity types: the product commodity, the “prosumer commodity,” and the player commodity. Furthermore, Candy Crush Saga’s commodity form is structured by a platformed modality of cultural production and circulation and therefore embedded in the political economy of its host platform.

    Full Text Available With the current pace of growth, India would emerge as a major player in the international market in terms of commodity consumption, production and trade. Going by trade volume and also the possibly as an identifiable influence on the price making process on the essential commodities, the futures and spot markets have shown major variations. Increased volatility in asset prices has been a major reason behind the integration of domestic financial markets with the international financial sector accentuating the demand for the trading in the derivative market. Though organized commodity trading has been in from the nineteenth century in India, the commodity derivative markets in the new form with nationwide electronic trading and access have opened the gates for speculators, hedgers and other market participants to capitalize on the development. The robust growth of the commodity markets can be observed in terms of number of commodities trade volumes and growing number of both the market participants and the commodity exchanges. Liquidity booms reflected by loose monetary policy are responsible for major surge in commodity prices globally in addition to direct tangible impacts of oil prices especially in developing countries with heavy oil imports like India. Futures markets are created to fulfill genuine desires economic functions of hedging and price discovery. But, enormous futures trading observed on the commodity exchanges have raised a host of issues like inflation guided by the fuelling principle implying the direct relationship between volatility and inflation. Huge price volatility in futures segment on the commodity exchanges has therefore raised concerns relating to the market efficiencies, infrastructure and knowledge and also their consequential impact on cash markets. The demand and supply side of the commodity price mechanism is traditionally governed by numerous factors including the climatic conditions, availability of critical

    This crosswalk is based on the premise that there is a connection between the way mineral commodities are used and how this use is reflected in the economy. Raw mineral commodities are the basic materials from which goods, finished products, or intermediate materials are manufactured or made. Mineral commodities are vital to the development of the U.S. economy and they impact nearly every industrial segment of the economy, representing 12.2 percent of the U.S. gross domestic product (GDP) in 2010 (U.S. Bureau of Economic Analysis, 2014). In an effort to better understand the distribution of mineral commodities in the economy, the U.S. Geological Survey (USGS) attempts to link the end uses of mineral commodities to the corresponding North American Industry Classification System (NAICS) codes.

    Carolina Arteaga Cabrales

    2014-01-01

    Full Text Available We study the effect of monetary policy shocks on commodity prices. While most of the literature has found that expansionary shocks have a positive effect on aggregate price indices, we study the effect on individual prices of a sample of four commodities. This set of commodity prices is essential to understand the dynamics of the balance of payments in Colombia. The analysis is based on structural VAR models; we identify monetary policy shocks following Kim (1999, 2003 upon quarterly data for commodity prices and their fundamentals for the period from 1980q1 to 2010q3. Our results show that commodity prices overshoot their long run equilibrium in response to a contractionary shock in the US monetary policy and, in contrast with literature, the response of the individual prices considered is stronger than what has been found in aggregate indices. Additionally, it is found that the monetary policy explains a substantial share of the fluctuations in prices.

    2016-09-01

    The law of extreme event occurrence attracts much research. The volatility recurrence intervals of Chinese commodity futures market prices are studied: the results show that the probability distributions of the scaled volatility recurrence intervals have a uniform scaling curve for different thresholds q. So we can deduce the probability distribution of extreme events from normal events. The tail of a scaling curve can be well fitted by a Weibull form, which is significance-tested by KS measures. Both short-term and long-term memories are present in the recurrence intervals with different thresholds q, which denotes that the recurrence intervals can be predicted. In addition, similar to volatility, volatility recurrence intervals also have clustering features. Through Monte Carlo simulation, we artificially synthesise ARMA, GARCH-class sequences similar to the original data, and find out the reason behind the clustering. The larger the parameter d of the FIGARCH model, the stronger the clustering effect is. Finally, we use the Fractionally Integrated Autoregressive Conditional Duration model (FIACD) to analyse the recurrence interval characteristics. The results indicated that the FIACD model may provide a method to analyse volatility recurrence intervals.

    Hardware and software design and system integration for an intelligent precision jigging robot (IPJR), which allows high precision assembly using commodity parts and low-precision bonding, is described. Preliminary 2D experiments that are motivated by the problem of assembling space telescope optical benches and very large manipulators on orbit using inexpensive, stock hardware and low-precision welding are also described. An IPJR is a robot that acts as the precise "jigging", holding parts of a local structure assembly site in place, while an external low precision assembly agent cuts and welds members. The prototype presented in this paper allows an assembly agent (for this prototype, a human using only low precision tools), to assemble a 2D truss made of wooden dowels to a precision on the order of millimeters over a span on the order of meters. The analysis of the assembly error and the results of building a square structure and a ring structure are discussed. Options for future work, to extend the IPJR paradigm to building in 3D structures at micron precision are also summarized.

    The Computational Plant or Cplant is a commodity-based distributed-memory supercomputer under development at Sandia National Laboratories. Distributed-memory supercomputers run many parallel programs simultaneously. Users submit their programs to a job queue. When a job is scheduled to run, it is assigned to a set of available processors. Job runtime depends not only on the number of processors but also on the particular set of processors assigned to it. Jobs should be allocated to localized clusters of processors to minimize communication costs and to avoid bandwidth contention caused by overlapping jobs. This report introduces new allocation strategies and performance metrics based on space-filling curves and one dimensional allocation strategies. These algorithms are general and simple. Preliminary simulations and Cplant experiments indicate that both space-filling curves and one-dimensional packing improve processor locality compared to the sorted free list strategy previously used on Cplant. These new allocation strategies are implemented in Release 2.0 of the Cplant System Software that was phased into the Cplant systems at Sandia by May 2002. Experimental results then demonstrated that the average number of communication hops between the processors allocated to a job strongly correlates with the job's completion time. This report also gives processor-allocation algorithms for minimizing the average number of communication hops between the assigned processors for grid architectures. The associated clustering problem is as follows: Given n points in {Re}d, find k points that minimize their average pairwise L{sub 1} distance. Exact and approximate algorithms are given for these optimization problems. One of these algorithms has been implemented on Cplant and will be included in Cplant System Software, Version 2.1, to be released. In more preliminary work, we suggest improvements to the scheduler separate from the allocator.

    The main purpose of this article is twofold to analyze: (a) the long-term relation among the commodities prices and between spot electricity market price and commodity prices, and (b) the short-term dynamics among commodity prices and between electricity prices and commodity prices. Data between 2002 and 2005 from the Spanish electricity market was used. Econometric methods were used in the analysis of the commodity spot price, namely the vector autoregression model, the vector error correction model and the granger causality test. The co-integration approach was used to analyze the long-term relationship between the common stochastic trends of four fossil fuel prices. One of the findings in the long-term relation is that the prices of fuel and the prices of Brent are intertwined, though the prices of Brent ten to 'move' to reestablish the price equilibrium. Another finding is that the price of electricity is explained by the evolution of the natural gas series. - Highlights: > We model energy commodity prices in the Spanish electricity market. > We examine the short and long-term relationships among commodities prices. > We examine short and long-term relationships using co-integration techniques. > We found that in the long run the prices of fuel and Brent are intertwined. > The evolution of price of electricity is explained by the evolution of price of gas.

  6. Agricultural and oil commodities: price transmission and market integration between US and Italy

    2014-08-01

    Full Text Available Purpose of this article it to get some evidences of market interaction between United States and Italy using the time series analysis of spot prices spanning from January 1999 to May 2012 for crude oil and three ag-commodities: wheat, corn and soybean. These crops have been selected for their relevance in ag-commodity exchanges between US and Italy markets. The integration between US and Italy agricultural markets is hypothesized for the consistent volume of crop traded between these two countries while the price transmission is related to the leading price signals of the CBT (Chicago Board of Trade. The integration between oil and ag-commodity markets is suggested both by the large use of energy intensive inputs, (fertilizer, seed, machinery in production of these ag-commodities, and their use in biofuel production. The results suggest: a for US market the evidence of market integration between crude oil and US ag-commodities; b for Italy the integration with US ag-commodity markets and less evidence of integration with the oil market. These results are valuable information both for the agents and policy makers contributing to improve the information accuracy to predict the price movements used by marketing operators for their strategies and policy makers to set up policies to re-establish conditions of market efficiency and allocate these ag-commodities in alternative market channels.

    Salmonella enterica infections are transmitted not only by animal-derived foods but also by vegetables, fruits, and other plant products. To clarify links between Salmonella serotypes and specific foods, we examined the diversity and predominance of food commodities implicated in outbreaks of salmonellosis during 1998-2008. More than 80% of outbreaks caused by serotypes Enteritidis, Heidelberg, and Hadar were attributed to eggs or poultry, whereas >50% of outbreaks caused by serotypes Javiana, Litchfield, Mbandaka, Muenchen, Poona, and Senftenberg were attributed to plant commodities. Serotypes Typhimurium and Newport were associated with a wide variety of food commodities. Knowledge about these associations can help guide outbreak investigations and control measures.

  10. Final Technical/Scientific Report: Commodity Scale Thermostable Enzymatic Transformations

    Energy Technology Data Exchange (ETDEWEB)

    James J. Lalonde; Brian Davison

    2003-08-30

    The conversion of corn starch to high fructose corn-syrup sweetener is a commodity process, producing over 3 billion kg/y. In the last step of the process, an enzyme catalyst is used to convert glucose to the much sweeter sugar fructose. Due to incomplete conversion in the last step, the syrup must be purified using a chromatographic separation technique, which results in equal quantities of water being added to the syrup, and finally the water must be evaporated (up to 1 lb of water/lb of syrup). We have estimated the energy requirement in the evaporation step to be on the order of 13 billion BTU's/y. This process inefficiency could be eliminated if a thermostable form of glucose isomerase (GI), the enzyme catalyst used in the final step, was developed. Our chosen strategy was to develop an immobilized form of the enzyme in which the protein is first crystallized and then chemically cross-linked to form an insoluble particle. This so-called cross-linked enzyme crystal (CLE C(reg. sign)) technology had been shown to be a powerful method for enzyme stabilization for several other protein catalysts. In this work we have developed more than 30 CLEC preparations of glucose isomerase and tested them for activity and stability. We found these preparations to be highly active, with a 10-50 fold rate per gram of catalyst increase over existing commercial catalysts. The initial rates were also higher at higher temperatures as expected, however the efficiency of the CLEC GI preparations unexpectedly rapidly decreased to a low constant value with use at the higher temperatures. At this point, the source of this activity loss is unclear, however during this loss, the catalyst is found to form a solid mass indicating either breakage of the chemical cross-links or simple aggregation of the particles. It is likely that the increased mass transfer resistance due to this agglomeration is a major component of the activity loss. This research suggests that one potentially

  13. Trends in economic scarcity of U. S. timber commodities. Forest Service Resource Bulletin

    Energy Technology Data Exchange (ETDEWEB)

    Skog, K.; Risbrudt, C.

    1982-04-01

    Scarcity of natural resources has been of concern to industrial societies since Malthus developed his theory of population growth and resource use in the late 18th century. Barnett and Morse, in 1963, tested the widely held premise that natural resource commodities are becoming more economically scarce. They concluded that of all major natural resource commodities-agricultural, mineral, and timber-only timber commodities were increasing in economic scarcity. In particular, sawlogs have shown consistent increases in economic scarcity since the late 1800's. Data were prepared for the Barnett and Morse study by Potter and Christy and subsequently updated by Potter and Christy and subsequently updated by Manthy to 1973. This paper extends and expands these data series on timber commodities. Specifically, information will be presented on one indicator of economic scarcity-trends in real prices (prices deflated by the general producer price index).

  14. Market interdependence among commodity prices based on information transmission on the Internet

    Science.gov (United States)

    Ji, Qiang; Guo, Jian-Feng

    2015-05-01

    Human behaviour on the Internet has become a synchro-projection of real society. In this paper, we introduce the public concern derived from query volumes on the Web to empirically analyse the influence of information on commodity markets (e.g., crude oil, heating oil, corn and gold) using multivariate GARCH models based on dynamic conditional correlations. The analysis found that the changes of public concern on the Internet can well depict the changes of market prices, as the former has significant Granger causality effects on market prices. The findings indicate that the information of external shocks to commodity markets could be transmitted quickly, and commodity markets easily absorb the public concern of the information-sensitive traders. Finally, the conditional correlation among commodity prices varies dramatically over time.

  18. Transgenic hybrid poplar for sustainable and scalable production of the commodity/specialty chemical, 2-phenylethanol.

    Directory of Open Access Journals (Sweden)

    Michael A Costa

    Full Text Available Fast growing hybrid poplar offers the means for sustainable production of specialty and commodity chemicals, in addition to rapid biomass production for lignocellulosic deconstruction. Herein we describe transformation of fast-growing transgenic hybrid poplar lines to produce 2-phenylethanol, this being an important fragrance, flavor, aroma, and commodity chemical. It is also readily converted into styrene or ethyl benzene, the latter being an important commodity aviation fuel component. Introducing this biochemical pathway into hybrid poplars marks the beginnings of developing a platform for a sustainable chemical delivery system to afford this and other valuable specialty/commodity chemicals at the scale and cost needed. These modified plant lines mainly sequester 2-phenylethanol via carbohydrate and other covalently linked derivatives, thereby providing an additional advantage of effective storage until needed. The future potential of this technology is discussed. MALDI metabolite tissue imaging also established localization of these metabolites in the leaf vasculature.

    Even though significant attempts have appeared in literature, the current perception of co-movement of commodity prices appear inadequate and static. In particular we focus on price movements between crude oil futures and a series of agricultural commodities and gold futures. A comparative framework is applied to identify changes in relationships through time and various cointegration methodologies and causality tests are employed. Our results indicate that co-movement is a dynamic concept and that some economic and policy development may change the relationship between commodities. Furthermore we show that biofuel policy buffers the co-movement of crude oil and corn futures until the crude oil prices surpass a certain threshold. - Highlights: > We show that co-movement of commodity futures is a temporal concept. > A variation in parallel movement between 2 large periods occurs. > Biofuel policy buffers parallel movement of corn and crude oil futures

    Elser, James J; Elser, Timothy J; Carpenter, Stephen R; Brock, William A

    2014-01-01

    Recent human population increase has been enabled by a massive expansion of global agricultural production. A key component of this "Green Revolution" has been application of inorganic fertilizers to produce and maintain high crop yields. However, the long-term sustainability of these practices is unclear given the eutrophying effects of fertilizer runoff as well as the reliance of fertilizer production on finite non-renewable resources such as mined phosphate- and potassium-bearing rocks. Indeed, recent volatility in food and agricultural commodity prices, especially phosphate fertilizer, has raised concerns about emerging constraints on fertilizer production with consequences for its affordability in the developing world. We examined 30 years of monthly prices of fertilizer commodities (phosphate rock, urea, and potassium) for comparison with three food commodities (maize, wheat, and rice) and three non-agricultural commodities (gold, nickel, and petroleum). Here we show that all commodity prices, except gold, had significant change points between 2007-2009, but the fertilizer commodities, and especially phosphate rock, showed multiple symptoms of nonlinear critical transitions. In contrast to fertilizers and to rice, maize and wheat prices did not show significant signs of nonlinear dynamics. From these results we infer a recent emergence of a scarcity price in global fertilizer markets, a result signaling a new high price regime for these essential agricultural inputs. Such a regime will challenge on-going efforts to establish global food security but may also prompt fertilizer use practices and nutrient recovery strategies that reduce eutrophication.

These increases in agricultural commodity prices resulted from many factors and it is very difficult to separate the individual impact of each of them, because they occurred in parallel. However, it is possible to indicate several main reasons for these price increases, which are: adverse changes in supply-demand relations in agricultural markets, increases in oil prices (and increases of the volatility of those prices, development of biofuel production from agricultural commodities (the first generation biofuels, dollar depreciation, an increase in operations of a speculative nature on commodity markets and improper economic policy that created an environment for the growth of prices of agricultural products.

    A brief surrey of ongoing research work done for improving and enhancing the properties of commodity polymers by the author and author's colleagues is given in this paper. A series of high performance polymers and polymer nanomaterials were successfully prepared through irradiation and stress-induced reactions of polymers and hydrogen bonding. The methods proposed are viable, easy in operation, clean and efficient.1. The effect of irradiation source (UV light, electron beam, γ -ray and microwave), irradiation dose, irradiation time and atmosphere etc. on molecular structure of polyolefine during irradiation was studied. The basic rules of dominating oxidation, degradation and cross-linking reactions were mastered. Under the controlled conditions, cross-linking reactions are prevented, some oxygen containing groups are introduced on the molecular chain of polyolefine to facilitate the interface compatibility of their blends. A series of high performance polymer materials: u-HDPE/PA6,u-HDPE/CaCO3, u-iPP/STC, γ-HDPE/STC, γ-LLDPE/ATH, e-HDPE, e-LLDPE and m-HDPEfilled system were prepared (u- ultraviolet light irradiated, γ- γ-ray irradiated, e- electron beam irradiated, m- microwave irradiated)2. The effect of ultrasonic irradiation, jet and pan-milling on structure and changes in properties of polymers were studied. Imposition of critical stress on polymer chain can cause the scission of bonds to form macroradicals. The macroradicals formed in this way may recombine or react with monomer or other radicals to form linear, branched or cross-linked polymers or copolymers. About 20 kinds of block/graft copolymers have been synthesized from polymer-polymer or polymer-monomer through ultrasonic irradiation.Through jet-milling, the molecular weight of PVC is decreased somewhat, the intensity of its crystalline absorption bonds becomes indistinct. The processability, the yield strength, strength at break and elongation at break of PVC get increased quite a lot after

    Full Text Available Though the agricultural sector contributes significantly to the Indian economy, it faces several bottlenecks, one of those being the antiquated laws governing agricultural marketing and price discovery, leading to low price realization by Indian farmers. In India, six national level exchanges offer commodity derivatives contracts on commodities, with some having electronic spot exchanges to facilitate spot trading of commodities. However, farmers' participation in these exchanges has been poor. ITC-ABD, one of the largest aggregators and exporters of Indian agri-commodities, has started using these exchange platforms to hedge price risk. With experience of over three decades in the agricultural sector, Mr. S. Sivakumar has a deep understanding of the commodity markets and the needs of Indian farmers. This interview aims to get an insight into his views on increasing farmers' participation in commodity derivatives trading and more importantly, to understand ITC-ABD's commodity hedging strategy.

  16. Near-zero U.S. Interest Rates, Primary Commodity Prices, and Financial Control in Emerging Markets

    Institute of Scientific and Technical Information of China (English)

    RONALD; I.; MCKINNON

    2014-01-01

    The U.S. Federal Reserve’s monetary policy at the center of the world dollar standard has a first-order impact on global financial stability. However, except in moments of international crises, the Fed focuses inward on domestic American economic indicators and generally ignores collateral damage from its monetary policies in the rest of the world. But this makes the U.S. economy less stable. Currently, ultra-low interest rates on dollar assets ignite waves of hot money into emerging markets by carry traders that generate bubbles in international primary commodity prices and other assets. These bubbles burst when some accident at the center, such as a banking crisis, causes a reflux of the hot money. Ironically, these near-zero interest rates hold back investment in the American economy itself.

    A headspace-solid phase microextraction-gas chromatography-mass spectrometric (HS-SPME-GC-MS, hereafter abbreviated as "SPME") method was developed for dedicated organophosphorus (OP) pesticides assessment in multiple vegetable and fruit commodities. Specific extraction variables were optimised to achieve harmonised extraction performance of eleven OPs in a great span of seven characteristic commodities cataloged in Codex Alimentarius Commission. Comprehensive validation study confirmed analytical robustness of the SPME treatment in turnip, green cabbage, French beans, eggplant, apple, nectarine and grapes. Based on range-specific evaluation, extraction of individual OPs was characterised by sub-ppb level sensitivity and a wide 0.01-2.5 mg L(-1) dynamic range. Effective sample clean-up afforded precise quantification (0.5-10.9% R.S.D.) within a 70-120% recovery range at the MRL levels specified for individual commodities. Compared to conventional methods currently used, the SPME treatment developed here is quick, accurate, and relatively environmental friendly; it represents an attractive, practical way to deliver international standards in OP screening routines.

    Full Text Available Time series models investigating the linkages between various asset markets (Commodity and Equity in India have assumed a symmetric and linear relationship between them. They examine these interrelationships by assuming the presence of a uniform economic state. However the returns from commodity futures and stock market do not show a continuous trend but exhibit time varying behaviour i.e. the returns of stocks might be higher in a certain economic condition and it may fall as the economic environment changes due to financial crises, oil price rise, rupee depreciation etc. Similarly the return of commodities is also subject to variation with the changing economic conditions due to which the basic assumptions of stationary and linearity of time series models gets refuted. Therefore, this paper empirically examines the interrelationships between commodity futures (Energy, Metal and Agriculture and stock markets in dynamic economic states by employing Markov Regime Switching model proposed by Hamilton (2005 which has the capability of capturing temporal asymmetries and nonlinear dynamics of time series. For each market a composite index indicating the overall movement and performance of a particular investment asset has been considered. In order to provide robust results this paper uses daily data from 2006 to 2014 which significantly represents different states in the Indian Economy. The result of the study confirms the impact of economic environment on Indian commodity and stock markets and validates the presence of two distinct regimes: a “tranquil regime” representing the state of economic expansion and a “crisis regime” representing the state of economic decline. Additionally, the result confirms that commodities and stock markets oscillate between high and low volatility regimes and this movement is different across different commodity class (Energy, Metal and Agriculture. In a portfolio, when commodity futures are combined with stock

  20. What commodities and countries impact inequality in the global food system?

    The global distribution of food production is unequal relative to the distribution of human populations. International trade can increase or decrease inequality in food availability, but little is known about how specific countries and commodities contribute to this redistribution. We present a method based on the Gini coefficient for evaluating the contributions of country and commodity specific trade to inequality in the global food system. We applied the method to global food production and trade data for the years 1986-2011 to identify the specific countries and commodities that contribute to increasing and decreasing inequality in global food availability relative to food production. Overall, international trade reduced inequality in food availability by 25%-33% relative to the distribution of food production, depending on the year. Across all years, about 58% of the total trade links acted to reduce inequality with ˜4% of the links providing 95% of the reduction in inequality. Exports from United States of America, Malaysia, Argentina, and Canada are particularly important in decreasing inequality. Specific commodities that reduce inequality when traded include cereals and vegetables. Some trade connections contribute to increasing inequality, but this effect is mostly concentrated within a small number of commodities including fruits, stimulants, and nuts. In terms of specific countries, exports from Slovenia, Oman, Singapore, and Germany act to increase overall inequality. Collectively, our analysis and results represent an opportunity for building an enhanced understanding of global-scale patterns in food availability.

  1. Determine the optimal carrier selection for a logistics network based on multi-commodity reliability criterion

    Lin, Yi-Kuei; Yeh, Cheng-Ta

    2013-05-01

    From the perspective of supply chain management, the selected carrier plays an important role in freight delivery. This article proposes a new criterion of multi-commodity reliability and optimises the carrier selection based on such a criterion for logistics networks with routes and nodes, over which multiple commodities are delivered. Carrier selection concerns the selection of exactly one carrier to deliver freight on each route. The capacity of each carrier has several available values associated with a probability distribution, since some of a carrier's capacity may be reserved for various orders. Therefore, the logistics network, given any carrier selection, is a multi-commodity multi-state logistics network. Multi-commodity reliability is defined as a probability that the logistics network can satisfy a customer's demand for various commodities, and is a performance indicator for freight delivery. To solve this problem, this study proposes an optimisation algorithm that integrates genetic algorithm, minimal paths and Recursive Sum of Disjoint Products. A practical example in which multi-sized LCD monitors are delivered from China to Germany is considered to illustrate the solution procedure.

  2. SUBJECTIVITY UNDER CONSUMERISM: THE TOTALIZATION OF THE SUBJECT AS A COMMODITY

    Directory of Open Access Journals (Sweden)

    2016-08-01

    Full Text Available Abstract This theoretical work discusses consumerism's processes of subjectivation and their psychological consequences. Its regime is studied through its social imaginary and its totalitarian character: the discourse of advertising, as a global hegemon, absorbs all forms of discourse and signification, thereby actualizing capitalism's telos - the colonization of the Lebenswelt under a great imperative: everything must become a commodity, especially the subject. A process of totalization of subjectivity occurs under a commodification logic centered on the representation: every image must be transformed into commodity-signs. Thus the consumption imaginary appears as a totalizing ideology, functioning as archaic représentations collectives (Durkheim and simulating a religious imaginary. It mass-produces subjectivity through participation mystique (Lévy-Bruhl with its commodity-signs (and their fetish and the whole imaginary. Its subject is defined as a bricolage of consumable commodity-signs, being therefore eternally fluid, performative, and ethereal. Thus it produces an anthropological mutation, the commodity-subject: a disposable, empty, thoroughly commodified self.

  3. Techniques for Analyzing the Attractiveness of International Commodity Markets Under Conditions of Economic Globalization

    2006-03-01

    Full Text Available This article examines existing techniques and proposes its own for analyzing the attractiveness of international commodity markets in light of the globalization of world economic processes. Taking into account the supranational nature of the world economic environment when examining categories in the attractiveness of international commodity markets, the author introduces a multilevel system of indicators: market attractiveness at the mega-level – global level; market attractiveness at the macro-level national level; market attractiveness at the mezo-level – level of an individual sector. The attractiveness of international commodity markets is considered to be the degree of conformity between market environment factors and the mega-, macro- and mezo-levels of the economic interests of enterprises concerning the entry into and strategies for their activity on the international commodity markets in the short-, medium- and long-term. The author designs a stage-by-stage technique for strategically analyzing the attractiveness of international commodity markets in order to frame efficient market strategies of enterprises. Relying on the proposed techniques, she rates the integrated indicators of market accessibility and the possibility of realizing the economic interests of enterprises in target markets, bringing the index data into a matrix of «market accessibility – opportunity for realizing the economic interests of enterprises.» The analysis of a country’s position in the matrix makes it possible to frame efficient market strategies for enterprises.

  4. Single-Commodity Vehicle Routing Problem with Pickup and Delivery Service

    Full Text Available We present a novel variation of the vehicle routing problem (VRP. Single commodity cargo with pickup and delivery service is considered. Customers are labeled as either cargo sink or cargo source, depending on their pickup or delivery demand. This problem is called a single commodity vehicle routing problem with pickup and delivery service (1-VRPPD. 1-VRPPD deals with multiple vehicles and is the same as the single-commodity traveling salesman problem (1-PDTSP when the number of vehicles is equal to 1. Since 1-VRPPD specializes VRP, it is hard in the strong sense. Iterative modified simulated annealing (IMSA is presented along with greedy random-based initial solution algorithm. IMSA provides a good approximation to the global optimum in a large search space. Experiment is done for the instances with different number of customers and their demands. With respect to average values of IMSA execution times, proposed method is appropriate for practical applications.

    Marcela Lascsáková

    2015-09-01

    Full Text Available In the paper the numerical model based on the exponential approximation of commodity stock exchanges was derived. The price prognoses of aluminium on the London Metal Exchange were determined as numerical solution of the Cauchy initial problem for the 1st order ordinary differential equation. To make the numerical model more accurate the idea of the modification of the initial condition value by the stock exchange was realized. By having analyzed the forecasting success of the chosen initial condition drift types, the initial condition drift providing the most accurate prognoses for the commodity price movements was determined. The suggested modification of the original model made the commodity price prognoses more accurate.

    Full Text Available We have examined challenges and economic prospects of establishing an organized Commodity Exchange in Ghana. We find that such a market will result in reduction in post-harvest losses through price stability, improvement in commodity price risk and credit risk management, provision of a transparent and competitive price discovery mechanism, reduction in transaction and marketing costs, and avoidance of making the mistakes of others. However, we also identify the challenges that should be resolved such as lack of laws and regulations specifically pertaining to the commodity exchange; inadequate financial support; lack of trading infrastructure; inadequate volume; liquidity problem; smallholder farms; lack of understanding of trading instruments; and government/political interference to this end. Overall policy implications suggest inadequate infrastructure and capacity building of market participants should be enhanced.

  15. Garuda: a scalable tiled display wall using commodity PCs.

    Science.gov (United States)

    Nirnimesh; Harish, Pawan; Narayanan, P J

    2007-01-01

    Cluster-based tiled display walls can provide cost-effective and scalable displays with high resolution and a large display area. The software to drive them needs to scale too if arbitrarily large displays are to be built. Chromium is a popular software API used to construct such displays. Chromium transparently renders any OpenGL application to a tiled display by partitioning and sending individual OpenGL primitives to each client per frame. Visualization applications often deal with massive geometric data with millions of primitives. Transmitting them every frame results in huge network requirements that adversely affect the scalability of the system. In this paper, we present Garuda, a client-server-based display wall framework that uses off-the-shelf hardware and a standard network. Garuda is scalable to large tile configurations and massive environments. It can transparently render any application built using the Open Scene Graph (OSG) API to a tiled display without any modification by the user. The Garuda server uses an object-based scene structure represented using a scene graph. The server determines the objects visible to each display tile using a novel adaptive algorithm that culls the scene graph to a hierarchy of frustums. Required parts of the scene graph are transmitted to the clients, which cache them to exploit the interframe redundancy. A multicast-based protocol is used to transmit the geometry to exploit the spatial redundancy present in tiled display systems. A geometry push philosophy from the server helps keep the clients in sync with one another. Neither the server nor a client needs to render the entire scene, making the system suitable for interactive rendering of massive models. Transparent rendering is achieved by intercepting the cull, draw, and swap functions of OSG and replacing them with our own. We demonstrate the performance and scalability of the Garuda system for different configurations of display wall. We also show that the

  19. The top 50 commodity chemicals: Impact of catalytic process limitations on energy, environment, and economics

    Energy Technology Data Exchange (ETDEWEB)

    Tonkovich, A.L.Y.; Gerber, M.A.

    1995-08-01

    The production processes for the top 50 U.S. commodity chemicals waste energy, generate unwanted byproducts, and require more than a stoichiometric amount of feedstocks. Pacific Northwest Laboratory has quantified this impact on energy, environment, and economics for the catalytically produced commodity chemicals. An excess of 0.83 quads of energy per year in combined process and feedstock energy is required. The major component, approximately 54%, results from low per-pass yields and the subsequent separation and recycle of unreacted feedstocks. Furthermore, the production processes, either directly or through downstream waste treatment steps, release more than 20 billion pounds of carbon dioxide per year to the environment. The cost of the wasted feedstock exceeds 2 billion dollars per year. Process limitations resulting from unselective catalysis and unfavorable reaction thermodynamic constraints are the major contributors to this waste. Advanced process concepts that address these problems in an integrated manner are needed to improve process efficiency, which would reduce energy and raw material consumption, and the generation of unwanted byproducts. Many commodity chemicals are used to produce large volume polymer products. Of the energy and feedstock wasted during the production of the commodity chemicals, nearly one-third and one-half, respectively, represents chemicals used as polymer precursors. Approximately 38% of the carbon dioxide emissions are generated producing polymer feedstocks.

The objectives of the research study are to investigate the value chain of carrot in Suthomadansih, as well as to analyze how the implementation of agropolitan program supports the value chain of carrot. Meanwhile, in order to investigate how the implementation of agropolitan program in suthomadansih supports to value chain of carrot, there are three indicators that will be identified; the development of supporting infrastructure, agribusiness system, and development of human resource (Iqbal and Iwan, 2009. Both of qualitative and quantitative analysis has been applied into the study with the performance table of the implementation of agropolitan program and value chain analysis as tool to conduct the analysis. Based on the value chain of carrot in Suthomadansih, some development programs from Local Government through the agropolitan program has been conducted from upstream to downstream of carrot commodity. However, some programs are failed to support the value chain of carrot so that the improvement of value chain of carrot could not be optimized. Those programs are Agribusiness Sub Terminal, Worta Cluster, Vitmaka, and Farm Road Improvement Program.The implementation of agropolitan program is not sustainable because of the absence of the budgets of local governments. The program is only implemented for 3 years (2007-2009 so that there are no significant effects of the program on the agricultural sector, especially for carrot commodity.

    Each year, >9 million foodborne illnesses are estimated to be caused by major pathogens acquired in the United States. Preventing these illnesses is challenging because resources are limited and linking individual illnesses to a particular food is rarely possible except during an outbreak. We developed a method of attributing illnesses to food commodities that uses data from outbreaks associated with both simple and complex foods. Using data from outbreak-associated illnesses for 1998-2008, we estimated annual US foodborne illnesses, hospitalizations, and deaths attributable to each of 17 food commodities. We attributed 46% of illnesses to produce and found that more deaths were attributed to poultry than to any other commodity. To the extent that these estimates reflect the commodities causing all foodborne illness, they indicate that efforts are particularly needed to prevent contamination of produce and poultry. Methods to incorporate data from other sources are needed to improve attribution estimates for some commodities and agents.

  8. [Assessment of the sensitizing potency of cosmetic ingredients and commodities. How will the ingredients of cosmetics and commodities be tested in Europe today and tomorrow?].

    Science.gov (United States)

    Peiser, M; Platzek, T; Luch, A

    2012-03-01

    Cosmetics and certain commodities are applied or used by consumers directly on the skin. Creams may remain on the skin for longer periods, hair is dyed multiple times per year, nickel ions can be released from studs and piercings in areas of skin damage or migrate from toy materials into the skin of children. Accordingly, using or handling such products always entails a risk for developing a contact allergy. Moreover, daily usage and repeated contacts to certain cosmetics and commodities might lead to repeated elicitation of contact eczema in people already sensitized against allergenic ingredients. Unfortunately, contact allergy is not curable. For the assessment of the allergenic potential of chemicals, only testing based on animal experiments was available in the past. In 2003, the 7(th) amendment of the Cosmetics Directive 76/768/EWG laid down a ban on animal testing of cosmetic ingredients and from 2013 a general marketing ban of such products as well. Therefore, the development and validation of non-animal methods for assessing the toxicological endpoint sensitization/allergenic potency of chemicals is a major task for the years ahead and remains equally a challenge for industry and regulatory agencies.

  10. Forecasting South African containers for international trade: A commodity-based approach

    Directory of Open Access Journals (Sweden)

    Jan H. Havenga

    2011-11-01

    Full Text Available The most common approach used internationally for forecasting international trade containers is models based on the correlation between container trade and economic growth. While the strong historical correlation is indisputable, this paper argues that there will be saturation in the propensity to containerise as all the suitable volumes of the underlying commodities shift to containers over time. In addition, the link between freight transport and GDP will decouple as more sustainable approaches to economic development, and therefore freight transport, are necessitated by economic and environmental realities. A commodity-based model, taking into account the underlying drivers of containerisation, is proposed here as a more realistic forecast of container demand. This could have a material impact on how large-scale investment decisions are directed.

    2014-01-01

    The rural commodity economy in the Edo period developed by leaps and bounds under the influence of institution,policy,technology and other factors. From the mid 17 th century,the specific area of cash crops gradually took shape in Japan and the largescale cultivation of cash crops greatly promoted the development of rural handicrafts,thereby creating the conditions for the initiation of the capitalist relations of production. The development of rural commodity economy not only changed the traditional mode of operation and production of Japanese farmers,but also accelerated the class differentiation,shook and disintegrated the economic foundation and class basis of Bakuhan society,and created the preconditions for the later Meiji Restoration.

    This paper assesses factors that potentially influence the volatility of crude oil prices and the possible linkage between this volatility and agricultural commodity markets. Stochastic volatility models are applied to weekly crude oil, corn, and wheat futures prices from November 1998 to January 2009. Model parameters are estimated using Bayesian Markov Chain Monte Carlo methods. Speculation, scalping, and petroleum inventories are found to be important in explaining the volatility of crude oil prices. Several properties of crude oil price dynamics are established, including mean-reversion, an asymmetry between returns and volatility, volatility clustering, and infrequent compound jumps. We find evidence of volatility spillover among crude oil, corn, and wheat markets after the fall of 2006. This can be largely explained by tightened interdependence between crude oil and these commodity markets induced by ethanol production.

  15. Balancing detail and scale in assessing transparency to improve the governance of agricultural commodity supply chains

    2016-03-01

    To date, assessments of the sustainability of agricultural commodity supply chains have largely relied on some combination of macro-scale footprint accounts, detailed life-cycle analyses and fine-scale traceability systems. Yet these approaches are limited in their ability to support the sustainability governance of agricultural supply chains, whether because they are intended for coarser-grained analyses, do not identify individual actors, or are too costly to be implemented in a consistent manner for an entire region of production. Here we illustrate some of the advantages of a complementary middle-ground approach that balances detail and scale of supply chain transparency information by combining consistent country-wide data on commodity production at the sub-national (e.g. municipal) level with per shipment customs data to describe trade flows of a given commodity covering all companies and production regions within that country. This approach can support supply chain governance in two key ways. First, enhanced spatial resolution of the production regions that connect to individual supply chains allows for a more accurate consideration of geographic variability in measures of risk and performance that are associated with different production practices. Second, identification of key actors that operate within a specific supply chain, including producers, traders, shippers and consumers can help discriminate coalitions of actors that have shared stake in a particular region, and that together are capable of delivering more cost-effective and coordinated interventions. We illustrate the potential of this approach with examples from Brazil, Indonesia and Colombia. We discuss how transparency information can deepen understanding of the environmental and social impacts of commodity production systems, how benefits are distributed among actors, and some of the trade-offs involved in efforts to improve supply chain sustainability. We then discuss the challenges and

  16. Inventories and Commodity Price Volatility: A Test of the Theory of Storage

    OpenAIRE

    The theory of storage implies that commodity price volatility is inversely related to inventories, and that as inventories decline, spot prices become relatively more volatile than futures prices, and vice versa. These implications are directly tested using inventory and price data for six non-ferrous metals traded on the London Metal Exchange over the period 1989 to 2000. The conditional variances are specified as multiplicative heteroskedasticity models. For four of the metals, the observed...

  18. What's nature got to do with it? A situated historical perspective on socio-natural commodities.

    Science.gov (United States)

    Peluso, Nancy Lee

    2012-01-01

    Nature(s) have been commodified since the early days of capitalism, but through processes and socio-natural relationships mediated by their times, histories and localities. While the conditions under which nature's commodities are being trademarked today may be new, their potential for commodification is not. Commodifications of nature should not come as a surprise to environmental social scientists and activists. In this article, I argue that commodification of ‘nature's products, places and processes’ produces new sorts of socio-natures. Situated histories of rubber are particularly relevant because, like carbon, ecosystem services and other recently commodified natures, rubber sits comfortably on the line between a fictitious commodity and a commodity produced explicitly for market: the latex alone has almost no use value, and to give it any exchange value, it requires processing. Yet analytically, it is still considered a ‘natural commodity’, different from ‘synthetic rubber’ and other tradable tree latexes in qualities and socio-natural characteristics. However, it is the social relations constituting rubber's production and trade in various rainforest and agro-forestry environments that have given it a positive or negative connotation, rather than its natural properties or the ecological contexts within which it has been produced. By situating rubber in three of its globally important temporal and spatial contexts, I show how it has been subjected to fairy-tale-like stories that masked and naturalized its commodity lives of the moment. Understanding how history is told or remains untold is thus an essential part of the politics of knowledge production, but also of human experience and mobilization for change. It should be part of any political ecology analysis.

    We have put together a desktop computer system for under 2.5 K dollars from commodity components that consist of one quad-core CPU (Intel Core 2 Quad Q6600 Kentsfield 2.4GHz) and two high end GPUs (nVidia's GeForce GTX 295 and Tesla C1060). A 1200 watt power supply is required. On this commodity system, we have constructed an easy-to-use hybrid computing environment, in which Message Passing Interface (MPI) is used for managing the working loads, for transferring the data among different GPU devices, and for minimizing the need of CPU’s memory. The test runs using the MAGMA (Matrix Algebra on GPU and Multicore Architectures) library show that the speed ups for double precision calculations can be greater than 10 (GPU vs. CPU) and they are bigger (> 20) for single precision calculations. In addition we have enabled the combination of Matlab with CUDA for interactive visualization through MPI, i.e., two GPU devices are used for simulation and one GPU device is used for visualizing the computing results as the simulation goes. Our experience with this commodity system has shown that running multiple applications on one GPU device or running one application across multiple GPU devices can be done as conveniently as on CPUs. With NVIDIA CEO Jen-Hsun Huang's claim that over the next 6 years GPU processing power will increase by 570x compared to the 3x for CPUs, future low-cost commodity computers such as ours may be a remedy for the long wait queues of the world's supercomputers, especially for small- and mid-scale computation. Our goal here is to explore the limits and capabilities of this emerging technology and to get ourselves ready to run large-scale simulations on the next generation of computing environment, which we believe will hybridize CPU and GPU architectures.

  5. Differential evolution algorithm for multi-commodity and multi-level of service hub covering location problem

    Directory of Open Access Journals (Sweden)

    M. Setak

    2013-01-01

    Full Text Available The hub location problem involves a network of origins and destinations over which transportation takes place. There are many studies associated with finding the location of hub nodes and the allocation of demand nodes to these located hub nodes to transfer the only one kind of commodity under one level of service. However, in this study, carrying different commodity types from origin to destination under various levels of services (e.g. price, punctuality, reliability or transit time is studied. Quality of services experienced by users such as speed, convenience, comfort and security of transportation facilities and services is considered as the level of service. In each system, different kinds of commodities with various levels of services can be transmitted. The appropriate level of service that a commodity can be transmitted through is chosen by customer preferences and the specification of the commodity. So, a mixed integer programming formulation for single allocation hub covering location problem, which is based on the idea of transferring multi commodity flows under multi levels of service is presented. These two are applied concepts, multi-commodity and multi-level of service, which make the model's assumptions closer to the real world problems. In addition, a differential evolution algorithm is designed to find near-optimal solutions. The obtained solutions using differential evolution (DE algorithm (upper bound, where its parameters are tuned by response surface methodology, are compared with exact solutions and computed lower bounds by linear relaxation technique to prove the efficiency of proposed DE algorithm.

  6. Natural Resources Management: The Effect of the Commodity Boom on Indonesia’s Industrial Development and Welfare

    Directory of Open Access Journals (Sweden)

    Maria Monica Wihardja

    2016-03-01

    Full Text Available The end of the commodity boom in 2012 once again exposed Indonesia to the vulnerability of the commodity price shocks. This article reviews how Indonesia managed its natural resources in 2001–12 and when the commodity boom ends. What are the lessons learned? Indonesia’s experience is similar to that of other countries rich in natural resources, including the crowding-out of non-commodity sectors, protectionist trade regimes, fiscal inefficiency, slow skill accumulation, rising inequality and environmental damages. In the aftermath of the global financial crisis of 2008–09, the early trade -policy response at the end of the commodity boom is inward-looking and protective of domestic markets and industries and aims to increase the added value of commodities by downstreaming. This trend is clearly reflected in the 2014 Trade Law, the 2014 Industry Law and the mineral export ban, which was introduced in 2009 through the 2009 Law on Mining of Coal and Minerals and took effect in 2014. Indonesia should learn from other countries in managing its resource revenues, such as through a commodity fund designed to fit its domestic specificity. Reindustrializing, increasing agricultural productivity beyond palm oil and tapping the country’s potential in the services sector including tourism and creative industries are also necessary to promote diversification in production and trade. Resource management policy should also include stronger environmental regulations.

  8. Applying commodity chain analysis to changing modes of alcohol supply in a developing country.

    Science.gov (United States)

    Jernigan, D H

    2000-12-01

    Development sociology has used global commodity chains as one way of analyzing the dynamics of power and profit-taking in globalized production networks made up of multiple firms and occurring in multiple national settings. A substantial portion of the alcohol supply in developing countries is now produced through such production networks. Particularly in the beer and spirits trade, a small number of transnational firms control networks of local producers, importers, advertisers and distributors. These networks serve to embed transnational or transnationally backed brands in the local culture, using the tools of market research, product design and marketing to influence local drinking practices. Case materials from Malaysia's beer industry help to illustrate how the transnational firms dominate in those links of the commodity chain in which monopoly or oligopoly control is most likely to be found: the design/recipe and marketing/advertising nodes. Their control of the commodity chains and extraction of monopoly or oligopoly profits from them places substantial resources and influence over drinking settings and practices in foreign hands. The impact of this influence on state efficacy and autonomy in setting alcohol policy is an important subject for future research on the creation and implementation of effective alcohol policies in developing societies.

  9. Evaluation of the impact of commodity price change on mine plan of underground mining

    Institute of Scientific and Technical Information of China (English)

    Salama Abubakary; Nehring Micah; Greberg Jenny

    2015-01-01

    Fluctuations in commodity prices should influence mining operations to continually update and adjust their mine plans in order to capture additional value under new market conditions. One of the adjust-ments is the change in production sequencing. This paper seeks to present a method for quantifying the net present value (NPV) that may be directly attributed to the change in commodity prices. The evaluation is conducted across ten copper price scenarios. Discrete event simulation combined with mixed integer programming was used to attain a viable production strategy and to generate optimal mine plans. The analysis indicates that an increase in prices results in an increased in the NPV from$96.57M to $755.65M. In an environment where mining operations must be striving to gain as much value as possible from the rights to exploit a finite resource, it is not appropriate to keep operating under the same mine plan if commodity prices alter during the course of operations.

    2011-10-01

    Understanding the dependence structure between the commodity and stock markets is a crucial issue in constructing a portfolio. It can also help us to discover new opportunities to implement spread trading using multiple assets classified in the two different markets. This study analyzed the dependence structure of the commodity and stock markets using the random matrix theory technique and network analysis. Our results show that the stock and commodity markets must be handled as completely separated asset classes except for the oil and gold markets, so the performance enhancement of the mean-variance portfolio is significant as expected. In light of the fact that WTI 1 month futures and four oil-related stocks are strongly correlated, they were selected as basic ingredients to complement the multi-spread convergence trading strategy using a machine learning technique called the AdaBoost algorithm. The performance of this strategy for non-myopic investors, who can endure short-term loss, can be enhanced significantly on a risk measurement basis.

  12. Regulatory Bodies: Dramatic Creativity, Control and the Commodity of Lady Audley's Secret

    Directory of Open Access Journals (Sweden)

    Kate Mattacks

    2009-04-01

    Full Text Available 'Lady Audley's Secret' resonates with a sense of theatricality grounded in the eponymous heroine's propensity for visual tactics to attract an audience. Repositioning the dramatic exchange between actress and audience within the domestic sphere sensitised the reader to the question of diagnosing morally degenerative artificiality whilst involving the reader in the complicit act of encouraging Lady Audley's performance through consumer demand. This complex relationship between consumerism, theatre and society saw Lady Audley's figure assume an iconic status, but little has been written on the creative interplay between the novel and the theatre itself. Beginning with the way in which aspiring actresses used Lady Audley as a model to display their histrionic variety, I argue that the theatre used her character to engage with the complex connections between drama and commodity culture. Her autophagy in favour of a false identity provided a model for actresses to visualise self-commodification whilst highlighting the tension between the material practices of the theatre and the materiality of commodity culture. The drive for regulation of the theatrical medium finds its locus in the licensing text/published acting edition of William E. Suter's 'Lady Audley's Secret' (1863. Here I move to show how Suter's adaptation functioned as a site where the state regulation of the theatre was explored and contested. These unauthorised images of Lady Audley's containment came to symbolise not only the regulatory processes of licensing and copyright, but also the creative exploitation of a commodity culture critiqued through the dehumanised form of Braddon's original heroine.

    Fresh agricultural commodities have been entering the era of network marketing. However,the coverage population is still relatively small. In this paper,more than 400 online shopping customer survey data are statistically analyzed based on perceived risk multidimensional model by factor analysis method to classify the potential customers’ perceived risk,concluding that food safety risks,mental health risk,relative convenience risk,liquidity risk,privacy risk and time risk are the most important risk factors that impact potential customers online shopping of fresh agricultural commodities. By using customers prediction model which is based on the classification and prediction methods to mining potential customers,it comes to the conclusion that men are more likely to purchase fresh agricultural commodities online,specifically,in the male sample,those whose average monthly net purchase cost equals to or is higher than 51 yuan or whose online shopping time equals to or is longer than 3 years and at the same time whose age is younger than 30 are the most potential customers. Finally,it puts forward corresponding countermeasures and suggestions from the perspectives of risk control and effective customer acquisition.

    Full Text Available The article is devoted to investigations of the relationship of commodity-production and financial network structures in the regional economy as dual conjugate systems. Material flows (raw materials, goods, etc. are circulating in the commodity network according to the Leontyev, input-output model. Nonmaterial flows of property rights, money, etc. in the financial network are reflecting the movement of material objects. Network structure is considered to be a complex of closed and open circuits that are carrying out two fundamentally different problems: a locally closed circuits are meeting local demands by supplying of locally produced goods that is providing self-reproduction of the local economy; open (or transit circuits are providing export-import flows. The generation mechanism of «internal» money in closed circuits of commodity-production network is presented. Obtained theoretical results are illustrated by calculations of closed and open circuit flows in the municipality economy model. The mathematical model represents the mutual payments of population and companies in matrix form. It is found that the volume of turnover in closed circuits is about 28.5 % of total municipality economy model turnover and can be assured by «internal» non-inflationary money. The remaining 71.5 % of total turnover are corresponding to the flows in open circuits of the network providing export and import activity. It is summarized that the priority of innovative economy projects should be given to domestic consumption rather than exports.

  15. Speculation on commodities futures markets and destabilization of global food prices: exploring the connections.

    Ghosh, Jayati; Heintz, James; Pollin, Robert

    2012-01-01

    In December 2010, the United Nations Food and Agriculture Organization's Food Price Index surpassed its previous peak of June 2008, and prices remained at this level through September 2011. This pattern is creating justified fears of a renewal or intensification of the global food crisis. This paper reviews arguments and evidence to inform debates on how to regulate commodity futures markets in the face of such price volatility and sustained high prices. We focus on the relationship between market liquidity and price patterns in asset markets in general and in commodities futures markets in particular, as well as the relationship between spot and futures market prices for food. We find strong evidence supporting the need to limit huge increases in trading volume on futures markets through regulations. We find that arguments opposing regulation are not supported. We find no support for the claim that liquidity in futures markets stabilizes prices at "fundamental" values or that spot market prices are free of any significant influence from futures markets. Given these results, the most appropriate position for regulators is precautionary: they should enact and enforce policies capable of effectively dampening excessive speculative trading on the commodities markets for food.

    The Freight Analysis Framework (FAF) integrates data from a variety of sources to create a comprehensive picture of nationwide freight movements among states and major metropolitan areas for all modes of transportation. It provides a national picture of current freight flows to, from, and within the United States, assigns selected flows to the transportation network, and projects freight flow patterns into the future. The latest release of FAF is known as FAF4 with a base year of 2012. The FAF4 origin-destination-commodity-mode (ODCM) matrix is provided at national, state, major metropolitan areas, and major gateways with significant freight activities (e.g., El Paso, Texas). The U.S. Department of Energy (DOE) is interested in using FAF4 database for its strategic planning and policy analysis, particularly in association with the transportation of energy commodities. However, the geographic specification that DOE requires is a county-level ODCM matrix. Unfortunately, the geographic regions in the FAF4 database were not available at the DOE desired detail. Due to this limitation, DOE tasked Oak Ridge National Laboratory (ORNL) to assist in generating estimates of county-level flows for selected energy commodities by mode of transportation.

    2012-01-01

    To obtain preliminary data on the drug supply management system in Ethiopia, selected facilities were assessed for the availability of essential drugs and commodities for malaria, TB and HIV. Of the 48 surveyed hospitals and health centers, 9 (19%), 9 (19%) and 10 (21%) did not have malaria, TB or HIV drugs, respectively. Similarly, of 27 health posts, 9 (33%) and 6 (22%) did not have rapid diagnostic tests and antimalarial drugs, respectively. The findings indicated an inadequate availability of essential drugs and commodities in the surveyed facilities as well as weaknesses in human resources and training. Assessments of commodity supply chains to ensure operational program success and impact are important.

  6. The Secret, Cultural Property and the Construction of the Spiritual Commodity

    Directory of Open Access Journals (Sweden)

    Guy Redden

    2012-09-01

    Full Text Available A randomised survey in Texas found that 22 per cent of the public identified themselves as consumers of New Age media. Despite widespread recognition of the ‘spiritual supermarket’ there has been little sustained analysis of the production of spiritual commodities and related issues of cultural property. This article presents a case study of the bestselling spiritual self-help book and DVD The Secret, which features various teachers and sacred wisdom traditions seen to hold the key to the meaning of life—but which has also been the subject of copyright disputes. Through this example the article examines ways informational commodities are produced by transforming freely available spiritual traditions into intellectual property for a contemporary market in self-help products. Two related tensions raised by this reconstruction are explored. The first is between cooperation and competition in the liberal New Age milieu where entrepreneurs present marginally differentiated goods and services side-by-side. In contrast with exclusionary organisation of religious doctrine, freedom to adapt the lingua franca of holistic spirituality allows for coefficiency among providers, but also new forms of ownership distinction, as exemplified by The Secret. The second tension is between these private property relations and the corporate cultural property of the custodians of knowledge traditions that are commodified. The Secret, as with much New Age syncretism and multiculturalism, depends upon particular processes of transvaluation that inscribe diversity as positive by rendering selected instantiations of it equivalent—in this case through universalising the therapeutic value of specific traditions have for modern life. Drawing in particular upon debates about New Age use of Indigenous Australian knowledges, the author questions how the reworking of wisdom into a commodity may bear upon the ethnocultural significance of sacred traditions and upon other

  7. Design of the advanced commode-shower chair for spinal cord-injured individuals.

    Malassigné, P; Nelson, A L; Cors, M W; Amerson, T L

    2000-01-01

    The purpose of this development project was to design a new commode-shower chair that can be safely used by individuals with spinal cord injuries (SCI) and their caregivers. The need for this new design was consumer-driven. Patients and caregivers identified the following fatal flaws in the commode-shower chairs used in Spinal Cord Injury (SCI) centers: 1) risk for patient falls during transfers, propelling, and while leaning over for showering; 2) risk for pressure ulcers due to inadequate padding and seat positioning for lengthy bowel care regimes; 3) inadequate caregiver access to the perianal area of the patient to perform bowel care procedures; and, 4) wheel-related inability to properly position the chair directly over the toilet. The new, self-propelled chair addresses each of these concerns. Lockable, swing-away, pivoting armrests and improved, lever-activated brakes were designed to facilitate safe transfers. An innovative foot-lift was invented to facilitate washing of feet. Larger handrims were designed to aid in propulsion in wet environments. To prevent pressure ulcers, a chair frame and padding combination was designed to facilitate a seating position that optimally distributes body weight to prevent the development of pressure ulcers in the sacral and ischial areas. To address the common risk of heel ulcers, footrests, featuring edgeless, rounded heel cups, were designed. A new tubular chair frame, a new seat and smaller wheels were designed to enhance caregiver access and ensure proper chair positioning over the toilet. Following its successful clinical evaluation at the Milwaukee and Tampa VA Medical SCI Centers, the Advanced commode-shower chair is being patented by the Department of Veterans Affairs (VA). The VA has partnered with Everest & Jennings, to make this chair available commercially.

    2015-01-01

    This study introduces the high yield, electrolytic synthesis of carbon nanofibers, CNFs, directly from carbon dioxide. Production of a precious commodity such as CNFs from atmospheric carbon dioxide provides impetus to limit this greenhouse gas and mitigate the rate of climate change. CNFs are formed at high rate using inexpensive nickel and steel electrodes in molten electrolytes. The process is demonstrated as a scaled-up stand-alone electrolytic cell, and is also shown compatible with the STEP, solar thermal electrochemical process, using concentrated sunlight at high solar to electric efficiency to provide the heat and electrical energy to drive the CNF production.

    The projected rise in food-related greenhouse gas emissions could seriously impede efforts to limit global warming to acceptable levels. Despite that, food production and consumption have long been excluded from climate policies, in part due to concerns about the potential impact on food security. Using a coupled agriculture and health modelling framework, we show that the global climate change mitigation potential of emissions pricing of food commodities could be substantial, and that levying greenhouse gas taxes on food commodities could, if appropriately designed, be a health-promoting climate policy in high-income countries, as well as in most low- and middle-income countries. Sparing food groups known to be beneficial for health from taxation, selectively compensating for income losses associated with tax-related price increases, and using a portion of tax revenues for health promotion are potential policy options that could help avert most of the negative health impacts experienced by vulnerable groups, whilst still promoting changes towards diets which are more environmentally sustainable.

    2016-10-01

    Full Text Available The aim of this paper is to present a new indoor localization approach by employing the Angle-of-arrival (AOA and Received Signal Strength (RSS measurements in Wi-Fi network. To achieve this goal, we first collect the Channel State Information (CSI by using the commodity Wi-Fi devices with our designed three antennas to estimate the AOA of Wi-Fi signal. Second, we propose a direct path identification algorithm to obtain the direct signal path for the sake of reducing the interference of multipath effect on the AOA estimation. Third, we construct a new objective function to solve the localization problem by integrating the AOA and RSS information. Although the localization problem is non-convex, we use the Second-order Cone Programming (SOCP relaxation approach to transform it into a convex problem. Finally, the effectiveness of our approach is verified based on the prototype implementation by using the commodity Wi-Fi devices. The experimental results show that our approach can achieve the median error 0.7 m in the actual indoor environment.

    2007-07-01

    The recent emergence of various types of flat-panel x-ray detectors and C-arm gantries now enables the construction of novel imaging platforms for a wide variety of clinical applications. Many of these applications require interactive 3D image generation, which cannot be satisfied with inexpensive PC-based solutions using the CPU. We present a solution based on commodity graphics hardware (GPUs) to provide these capabilities. While GPUs have been employed for CT reconstruction before, our approach provides significant speedups by exploiting the various built-in hardwired graphics pipeline components for the most expensive CT reconstruction task, backprojection. We show that the timings so achieved are superior to those obtained when using the GPU merely as a multi-processor, without a drop in reconstruction quality. In addition, we also show how the data flow across the graphics pipeline can be optimized, by balancing the load among the pipeline components. The result is a novel streaming CT framework that conceptualizes the reconstruction process as a steady flow of data across a computing pipeline, updating the reconstruction result immediately after the projections have been acquired. Using a single PC equipped with a single high-end commodity graphics board (the Nvidia 8800 GTX), our system is able to process clinically-sized projection data at speeds meeting and exceeding the typical flat-panel detector data production rates, enabling throughput rates of 40-50 projections s-1 for the reconstruction of 5123 volumes.

    The Massachusetts Institute of Technology (MIT) and Siemens Corporations (SCR) are developing new chemical synthesis processes for commodity chemicals from CO2. The process is assessed as a novel chemical sequestration technology that utilizes CO2 from dilute gas streams generated at industrial carbon emitters as a raw material to produce useful commodity chemicals. Work at Massachusetts Institute of Technology (MIT) commenced on October 1st, 2010, and finished on September 30th, 2013. During this period, we have investigated and accomplished five objectives that mainly focused on converting CO2 into high-value chemicals: 1) Electrochemical assessment of catalytic transformation of CO2 and epoxides to cyclic carbonates; 2) Investigation of organocatalytic routes to convert CO2 and epoxide to cyclic carbonates; 3) Investigation of CO2 Capture and conversion using simple olefins under continuous flow; 4) Microwave assisted synthesis of cyclic carbonates from olefins using sodium bicarbonates in a green pathway; 5) Life cycle analyses of integrated chemical sequestration process. In this final report, we will describe the detailed study performed during the three year period and findings and conclusions drawn from our research.

    2008-12-01

    The recent massive increase in food and energy prices in the past five years, coupled with the awareness of the long term challenges of climate change to small holder agriculture in Africa has brought the issue of food security for the world's poorest people to the forefront once again. Asymmetric and limited integration of local commodity markets in West Africa highlights the weak position of Africa's rural countries in the face of climate change and demographic expansion. This paper will describe the functioning of local informal food markets in West African over the past twenty years and evaluate the impact of their limited integration with each other and with global commodity markets. Satellite remote sensing of vegetation has been used as a proxy for agricultural production in economic models to improve prediction of large swings in prices from year to year due to differences in supply. As demand increases, improvements in market functioning will be necessary to counter likely increases in production variability. Increasing Africa's stability in the face of climate change will require investment in agricultural production and transportation infrastructure in order to ensure an affordable flow of food to people in these extremely poor, landlocked countries.

  5. Wild Commodities and Environmental Governance: Transforming Lives and Markets in China and Japan

    Directory of Open Access Journals (Sweden)

    Michael Hathaway

    2014-01-01

    Full Text Available This paper explores the relationship between forms of environmental governance and a transnational commodity chain for a wild mushroom that is picked in China and shipped to Japan. I argue that unlike some portrayals of environmental governance that largely assume a unified system working towards similar goals, governance comes from a number of sources and exhibits a range of forms, which at times overlap and contradict each other. In particular, this paper reflects on notions of commodification that are often argued to be part of neoliberal environmental governance. I show that diverse forms of environmental governance are shaping the texture of commodity chains, but not always working towards the overall increase in commodification. For example, in the last decade, the matsutake economy in China has been strongly influenced by several forms of environmental governance, such as a large-scale logging ban, the declaration of the matsutake as an endangered species, and its scrutiny in Japan as a potential object of contamination. I suggest that each of these forms of governance shapes the conditions of possibility and inflects the dynamics of this chain in different ways.

  6. Distributional assumptions in food and feed commodities- development of fit-for-purpose sampling protocols.

    Paoletti, Claudia; Esbensen, Kim H

    2015-01-01

    Material heterogeneity influences the effectiveness of sampling procedures. Most sampling guidelines used for assessment of food and/or feed commodities are based on classical statistical distribution requirements, the normal, binomial, and Poisson distributions-and almost universally rely on the assumption of randomness. However, this is unrealistic. The scientific food and feed community recognizes a strong preponderance of non random distribution within commodity lots, which should be a more realistic prerequisite for definition of effective sampling protocols. Nevertheless, these heterogeneity issues are overlooked as the prime focus is often placed only on financial, time, equipment, and personnel constraints instead of mandating acquisition of documented representative samples under realistic heterogeneity conditions. This study shows how the principles promulgated in the Theory of Sampling (TOS) and practically tested over 60 years provide an effective framework for dealing with the complete set of adverse aspects of both compositional and distributional heterogeneity (material sampling errors), as well as with the errors incurred by the sampling process itself. The results of an empirical European Union study on genetically modified soybean heterogeneity, Kernel Lot Distribution Assessment are summarized, as they have a strong bearing on the issue of proper sampling protocol development. TOS principles apply universally in the food and feed realm and must therefore be considered the only basis for development of valid sampling protocols free from distributional constraints.

Commodity chains are central mechanisms for these surplus drains in the world-economy. At each node of the chain, participants attempt to maximize their capture of bright value through wages, rent and profit. They do this by constructing differential degrees of monopoly (control of the markup between cost and sale price and degrees of monopsony (control of markdowns of production costs. However, this process depends upon the transformation of dark value into bright value for capture. Via an examination of the Apple iPad commodity chain, I show how the bright value captured by Apple depends on the dark value extracted by its suppliers. Dark value is estimated by measurements of the value of under-payments for wage labor, reproductive labor and environmental damage in Asian countries, especially China. Surprisingly, most dark value embedded in the iPad is captured by final buyers (mostly in the core as consumer surplus.

    This Exploratory LDRD aimed to develop molecular breeding methodology for biofuel algal strain improvement for applications in waste to energy / commodity conversion technologies. Genome shuffling technologies, specifically protoplast fusion, are readily available for the rapid production of genetic hybrids for trait improvement and have been used successfully in bacteria, yeast, plants and animals. However, genome fusion has not been developed for exploiting the remarkable untapped potential of eukaryotic microalgae for large scale integrated bio-conversion and upgrading of waste components to valued commodities, fuel and energy. The proposed molecular breeding technology is effectively sexual reproduction in algae; though compared to traditional breeding, the molecular route is rapid, high-throughput and permits selection / improvement of complex traits which cannot be accomplished by traditional genetics. Genome fusion technologies are the cutting edge of applied biotechnology. The goals of this Exploratory LDRD were to 1) establish reliable methodology for protoplast production among diverse microalgal strains, and 2) demonstrate genome fusion for hybrid strain production using a single gene encoded trait as a proof of the concept.

    International commerce places unique pressures on the sustainability of water resources and marine environments. System impacts include noise, emissions, and chemical and biological pollutants like introduction of invasive species into key ecosystems. At the same time, maritime trade also enables the sustainability ambition of intragenerational equity in the economy through the global circulation of commodities and manufactured goods, including agricultural, energy and mining resources (UN Trade and Development Board 2013). This paper presents a framework to guide the analysis of the multiple dimensions of the sustainable commerce-ocean nexus. As a demonstration case, we explore the social, economic and environmental aspects of the nexus framework using scenarios for the production and transportation of conventional and bio-based energy commodities. Using coupled LCA and GIS methodologies, we are able to orient the findings spatially for additional insight. Previous work on the sustainable use of marine resources has focused on distinct aspects of the maritime environment. The framework presented here, integrates the anthropogenic use, governance and impacts on the marine and coastal environments with the natural components of the system. A similar framework has been highly effective in progressing the study of land-change science (Turner et al 2007), however modification is required for the unique context of the marine environment. This framework will enable better research integration and planning for sustainability objectives including mitigation and adaptation to climate change, sea level rise, reduced dependence on fossil fuels, protection of critical marine habitat and species, and better management of the ocean as an emerging resource base for the production and transport of commodities and energy across the globe. The framework can also be adapted for vulnerability analysis, resilience studies and to evaluate the trends in production, consumption and

    Full Text Available Agricultural sector plays an important role in Indonesia‟s economy; especially for the plantation sub-sector contributing high revenues to Indonesia‟s exporting sectors. The primary agricultural commodities in Indonesian export discussed in this study would be Crude Palm Oil (CPO, Natural Rubber TSR20, Arabica Coffee, Robusta Coffee, Cocoa, White Pepper and Black Pepper. Meanwhile, the returns volatility nature of agricultural commodity is famous. The volatility refers to heteroscedasticity nature of the returns which can be modeled by GARCH-type models. The returns volatility can be describe by the residual of the mean equation and volatility of error variances in the previous periods. The aims of this study are to examine the predictability of GARCH-type models on the returns volatility of those seven agricultural commodities and to determine the best GARCH-type models for each commodity based on the traditional symmetric evaluation statistics. The results find that the predictability of ARCH, GARCH, GARCH-M, EGACRH and TGARCH, as type of GARCH models used in this study, are different for each commodity.

    As part of the Spreader Bar Radiation Detector project, PNNL analyzed US import data shipped through US ports collected over the 12 months of 2006 (over 4.5 million containers). Using these data, we extracted a variety of distributions that are of interest to modelers and developers of active and passive detection systems used to 'scan' IMCCs for potential contraband. This report expands on some of the analysis presented in an earlier report from LLNL, by investigation the foreign port distribution of commodities shipped to the US. The majority of containers shipped to the United States are 40 ft containers ({approx}70%); about 25% are 20 ft; and about 3.6% are 45 ft containers. A small fraction (<1%) of containers are of other more specialized sizes, and very few ports actually ship these unique size containers (a full distribution for all foreign ports is shown in Appendix A below). The primary foreign ports that ship the largest fraction of each container are shown in the table below. Given that 45 ft containers comprise 1 of out every 27 containers shipped to the US, and given the foreign ports from which they are shipped, they should not be ignored in screening; further testing and analysis of radiation measurements for national security with this size container is warranted. While a large amount of NORM is shipped in IMCCs, only a few specific commodities are shipped with enough frequency to present potential issues in screening IMCCs at ports. The majority of containers with NORM will contain fertilizers (5,700 containers), granite (59,000 containers), or ceramic (225,000 containers) materials. Fertilizers were generally shipping in either 20- or 40 ft containers with equal frequency. While granite is mostly shipped in 20 ft containers, ceramic materials can be shipped in either 20- or 40 ft containers. The size of container depended on the specific use of the ceramic or porcelain material. General construction ceramics (such as floor and roofing

  14. On the importance of commodity and energy price shocks for the macroeconomy

    Science.gov (United States)

    Edelstein, Paul S.

    Although higher commodity prices are commonly thought to presage higher rates of inflation, the existing literature suggests that the predictive power of commodity prices for inflation has waned since the 1980s. In the first chapter, I show that this result can be overturned using state-of-the-art forecast combination methods. Moreover, commodity prices are shown to contain predictive information not contained in the leading principal components of a broad set of macroeconomic and financial variables. These improved inflation forecasts are of little value, however, for predicting actual Fed policy decisions. The remaining two chapters study the effect of energy price shocks on U.S. consumer and business expenditures. In the second chapter, I show that there is no statistical support for the presence of asymmetries in the response of real consumption to energy price increases and decreases. This finding has important implications for empirical and theoretical models of the transmission of energy price shocks. I then quantify the direct effect on real consumption of (1) unanticipated changes in discretionary income, (2) shifts in precautionary savings, and (3) changes in the operating cost of energy-using durables. Finally, I trace the declining importance of energy price shocks relative to the 1970s to changes in the composition of U.S. automobile production and the declining overall importance of the U.S. automobile sector. An alternative source of asymmetry is the response of nonresidential fixed investment to energy price shocks. In the third chapter, I show that the apparent asymmetry in the estimated responses of business fixed investment in equipment and structures is largely an artifact (1) of the aggregation of mining-related expenditures by the oil, natural gas, and coal mining industry and all other expenditures, and (2) of ignoring an exogenous shift in investment caused by the 1986 Tax Reform Act. Once symmetry is imposed and miningrelated expenditures

    Terminological requirements in information management was but one of the principal themes of the 2nd Congress on Terminology and Knowledge Engineering. The traveler represented the American Society for Testing and Materials' Committee on Terminology, of which he is the Chair. The traveler's invited workshop emphasized terminology standardization requirements in databases of material properties as well as practical terminology standardizing methods. The congress included six workshops in addition to approximately 82 lectures and papers from terminologists, artificial intelligence practitioners, and subject specialists from 18 countries. There were approximately 292 registrants from 33 countries who participated in the congress. The congress topics were broad. Examples were the increasing use of International Standards Organization (ISO) Standards in legislated systems such as the USSR Automated Data Bank of Standardized Terminology, the enhanced Physics Training Program based on terminology standardization in Physics in the Chinese province of Inner Mongolia, and the technical concept dictionary being developed at the Japan Electronic Dictionary Research Institute, which is considered to be the key to advanced artificial intelligence applications. The more usual roles of terminology work in the areas of machine translation. indexing protocols, knowledge theory, and data transfer in several subject specialties were also addressed, along with numerous special language terminology areas.

    Full Text Available In this study, we evaluate the spillover effects of the recent U.S. Federal Reserve’s purchase of longterm assets (quantitative easing on prices of Canadian commodities. The first large-scale asset purchases happened after the Great Recession, at the end of 2008, and the second purchases were in November of 2010. Since the U.S. is a large country, those policies have international spillover effects, particularly on Canada, a major economic partner. The commodities included in this analysis are Canadian livestock (cattle, hogs, and poultry, cereal grains (corn, soybeans, and wheat, softs (sugar, coffee, and cocoa, and energy (crude oil and natural gas. Using historical decomposition graphs, we find significant spillover effects on the Canadian commodity prices under investigation in the immediate neighborhood (seven-month horizon of the large-scale asset purchases, especially the second round of quantitative easing.

    2011-11-01

    This paper extends two models for stochastic multi-commodity facility location problem. The problem is formulated as two-stage stochastic programming. As a main point of this study, a new algorithm is applied to efficiently generate scenarios for uncertain correlated customers' demands. This algorithm uses Latin Hypercube Sampling (LHS) and a scenario reduction approach. The relation between customer satisfaction level and cost are considered in model I. The risk measure using Conditional Value-at-Risk (CVaR) is embedded into the optimization model II. Here, the structure of the network contains three facility layers including plants, distribution centers, and retailers. The first stage decisions are the number, locations, and the capacity of distribution centers. In the second stage, the decisions are the amount of productions, the volume of transportation between plants and customers.

    This study investigates the efficiency of the Chinese metal futures (i.e. copper and aluminum) traded on China's Shanghai Futures Exchange. First, we thoroughly analyze the development of China's commodity futures markets, which provides a fundamental background. Then we examine the random walk and unbiasedness hypotheses for two metal futures during 1999-2004. Based on the empirical evidence, we argue that China's copper and aluminum futures markets are efficient, and that they aid the process of price discovery because futures prices can be considered as unbiased predictors of future spot prices. We attribute this efficiency to the regulatory changes made in 1999 and the increased financial skills and acumen of the participants in the market.

    2012-01-01

    The US Food and Drug Administration is expected to approve AquAdvantage Salmon as the first genetically modified animal for human consumption. The genetic modifications allow the proprietary fish to grow at a rate twice as fast as a wild salmon, leading to greater ‘efficiency’ in terms of reduced costs and reduced time to market. This article provides an analysis of the ways in which AquAdvantage Salmon exemplifies capitalist market forces controlling and guiding the terms of salmon recovery and conservation. The authors trace historical developments within the salmon industry to demonstrate how capitalist commodity production has impacted fishing communities. They reject the oft-cited ‘tragedy of the commons’ hypothesis offered to explain fisheries crises. In its place, they offer the conceptual framework of the ‘tragedy of the commodity’ to explore how capitalist market forces and complicit state regulations amplify rather than resolve global environmental problems.

  1. Too Human versus the enthusiast press: Video game journalists as mediators of commodity value

    Directory of Open Access Journals (Sweden)

    Rebecca Carlson

    2009-03-01

    Full Text Available This article examines the role of mediators in the production of commodity value, arguing that there is a rise in a kind of immaterial labor, shaped by contemporary conditions of late capitalism, that functions explicitly as a mediating force. In this example, video game journalists are understood as actively engaged in producing and negotiating the value and meaning of video games for both producers and consumers. By specifically examining a moment of value contestation, a podcast debate between a journalist and a game developer, this article traces the mediating practices of the enthusiast gaming press and examines the way their history with and relationship to the video game industry continue to structure their ability to filter knowledge and shape desires.

    Fermentation of syngas is a means through which unutilized organic waste streams can be converted biologically into biofuels and commodity chemicals. Despite recent advances, several issues remain which limit implementation of industrial-scale syngas fermentation processes. At the cellular level, the energy conservation mechanism of syngas fermenting microorganisms has not yet been entirely elucidated. Furthermore, there was a lack of genetic tools to study and ultimately enhance their metabolic capabilities. Recently, substantial progress has been made in understanding the intricate energy conservation mechanisms of these microorganisms. Given the complex relationship between energy conservation and metabolism, strain design greatly benefits from systems-level approaches. Numerous genetic manipulation tools have also been developed, paving the way for the use of metabolic engineering and systems biology approaches. Rational strain designs can now be deployed resulting in desirable phenotypic traits for large-scale production.

    We have recently been running earthquake ground motion simulations with SW4 on the new capacity computing systems, called the Commodity Technology Systems - 1 (CTS-1) at Lawrence Livermore National Laboratory (LLNL). SW4 is a fourth order time domain finite difference code developed by LLNL and distributed by the Computational Infrastructure for Geodynamics (CIG). SW4 simulates seismic wave propagation in complex three-dimensional Earth models including anelasticity and surface topography. We are modeling near-fault earthquake strong ground motions for the purposes of evaluating the response of engineered structures, such as nuclear power plants and other critical infrastructure. Engineering analysis of structures requires the inclusion of high frequencies which can cause damage, but are often difficult to include in simulations because of the need for large memory to model fine grid spacing on large domains.

  4. A Future beyond HIV/AIDS? Health as a Political Commodity in Botswana

    Directory of Open Access Journals (Sweden)

    Astrid Bochow

    2015-01-01

    Full Text Available Referencing scholarly debates on humanitarianism and specifically HIV interventions, this article analyses the commodification of health in Botswana’s political arena throughout the HIV pandemic and beyond, contributing to a re-evaluation of the distribution of public wealth and international support in welfare states in Africa. The starting point of the analysis is a project to build a private hospital – a move to create a centre of excellence exclusive of international HIV/AIDS donations – and the staging of political responsibilities around it. Public investment into private health is an attempt to reform infrastructures built with HIV/AIDS money and to develop a market of high-paying jobs within the country. This process transforms the inalienable and indivisible condition of health and survival into a political commodity.

    2017-03-01

    This study reveals that reduction of carbon dioxide (CO2) to commodity chemicals can be functionally compartmentalized in bioelectrochemical systems. In the present example, a syntrophic consortium composed by H2-producers (Rhodobacter sp.) in the biofilm is combined with carboxidotrophic Clostridium species, mainly found in the bulk liquid. The performance of these H2-mediated electricity-driven systems could be tracked by the activity of a biological H2 sensory protein identified at cathode potentials between -0.2V and -0.3V vs SHE. This seems to point out that such signal is not strain specific, but could be detected in any organism containing hydrogenases. Thus, the findings of this work open the door to the development of a biosensor application or soft sensors for monitoring such systems.

    Since the publication of Plant, Hammond, and Turner (2004), which highlighted a pressing need for researchers to pay more attention to sources of error in computer-based experiments, the landscape has undoubtedly changed, but not necessarily for the better. Readily available hardware has improved in terms of raw speed; multi core processors abound; graphics cards now have hundreds of megabytes of RAM; main memory is measured in gigabytes; drive space is measured in terabytes; ever larger thin film transistor displays capable of single-digit response times, together with newer Digital Light Processing multimedia projectors, enable much greater graphic complexity; and new 64-bit operating systems, such as Microsoft Vista, are now commonplace. However, have millisecond-accurate presentation and response timing improved, and will they ever be available in commodity computers and peripherals? In the present article, we used a Black Box ToolKit to measure the variability in timing characteristics of hardware used commonly in psychological research.

    Caroline M. van Ommeren

    2013-07-01

    Full Text Available In the uplands of Central Java a wide variety of dry cultivated crops are produced for subsistence as well as for cash. The marketing channels for these crops are also diverse. The producers can choose between selling at the market place or at their farms; either to consumers or traders; or they can sell their products to wholesalers in the towns. However, this freedom of choice is not absolute and is determined by the quantity of the merchandise. Farmers/who can sell large amounts of produce are able to bypass some steps in the hierarchical order of market places or traders. Thus, producers with relatively large farmlands can sell their commodities in more profitable ways compared to those with /smaller farms. Moreover, the latter are often forced to sell their produce below market value to traders who provided them with advance or who bought the crop before harvest (tebasan, because of their need for cash

    2016-12-15

    Many plant derived commodities contain traces of toxic pyrrolizidine alkaloids (PAs). The main source of these contaminations seems to be the accidental co-harvest of PA-containing weeds. Yet, based on the insights of the newly described phenomenon of the horizontal transfer of natural products, it is very likely that the PA-contaminations may also be due to an uptake of the alkaloids from the soil, previously being leached out from rotting PA-plants. The transfer of PAs was investigated using various herbs, which had been mulched with dried plant material from Senecio jacobaea. All of the acceptor plants exhibited marked concentrations of PAs. The extent and the composition of the imported PAs was dependent on the acceptor plant species. These results demonstrate that PAs indeed are leached out from dried Senecio material into the soil and confirm their uptake by the roots of the acceptor plants and the translocation into the leaves.

    2000-01-01

    We describe a scalable parallelization of Geant4 using commodity hardware in a collaborative effort between the College of Computer Science and the Department of Physics at Northeastern University. The system consists of a Beowulf cluster of 32 Pentium II processors with 128 MBytes of memory each, connected via ATM and fast Ethernet. The bulk of the parallelization is done using TOP-C (Task Oriented Parallel C), software widely used in the computational algebra community. TOP-C provides a flexible and powerful framework for parallel algorithm development, is easy to learn, and is available at no cost. Its task oriented nature allows one to parallelize legacy code while hiding the details of interprocess communications. Applications include fast interactive simulation of computationally intensive processes such as electromagnetic showers. General results motivate wider applications of TOP-C to other simulation problems as well as to pattern recognition in high energy physics.

    Full Text Available This article aims to discuss the overall picture of education as the prism of the multilateral organizations of direct influence on regional policies, especially in developing countries. The concept of education as a business sector and opening up foreign investment in education by the WTO, World Bank and IMF, is an abrupt change in educational relations and set the foundations for an educational exclusion increasingly in developing countries. The role of UNESCO and its representation as a legitimate international authority in partnership with the World Bank put in doubt the real interests of the goals of both institutions in the world and the direct consequences of this relationship in the education field. And what can we expect of education policies based on international agreements with funding agencies? Education as commodity will be the future?

  12. Electrobiocommodities: powering microbial production of fuels and commodity chemicals from carbon dioxide with electricity

    Energy Technology Data Exchange (ETDEWEB)

    Lovley, DR; Nevin, KP

    2013-06-01

    Electricity can be an energy source for microbially catalyzed production of fuels and other organic commodities from carbon dioxide. These electrobiocommodities (E-BCs) can be produced directly via electrode-to-microbe electron transfer or indirectly with electrochemically generated electron donors such as H-2 or formate. Producing E-BCs may be a more efficient and environmentally sustainable strategy for converting solar energy to biocommodities than approaches that rely on biological photosynthesis. A diversity of microbial physiologies could potentially be adapted for E-BC production, but to date acetogenic microorganisms are the only organisms shown to covert electrically generated low potential electrons and carbon dioxide into multi-carbon organic products with high recovery of electrons in product. Substantial research and development will be required for E-BC commercialization.

    Directory of Open Access Journals (Sweden)

    D. Burakov

    2016-06-01

    Full Text Available In this paper, we investigate long and short-term impact of changes in oil prices and the exchange rate on prices of seven groups of agricultural products in Russia (buckwheat, grain crops, potatoes, oat, wheat, rye, barley. In this paper, Granger causality approach is applied to test long-run interlinkages with monthly data from January 1999 to October 2015. For testing the response of agricultural prices to sudden shocks in oil prices and exchange rate in the short run, we use impulse-response techniques. The results of impulse response analysis show that agricultural prices are not particularly sensitive to changes in oil prices and the exchange rate of Russian ruble in the short term, except for imported commodities. In the long run, Granger causal relationship between agricultural prices and oil prices is missing, and with exchange rate is observed only in case of imported agricultural goods.

    2014-04-01

    This study investigates the optimal supply chain design for commodity chemicals (BTX, etc.) production via woody biomass fast pyrolysis and hydroprocessing pathway. The locations and capacities of distributed preprocessing hubs and integrated biorefinery facilities are optimized with a mixed integer linear programming model. In this integrated supply chain system, decisions on the biomass chipping methods (roadside chipping vs. facility chipping) are also explored. The economic objective of the supply chain model is to maximize the profit for a 20-year chemicals production system. In addition to the economic objective, the model also incorporates an environmental objective of minimizing life cycle greenhouse gas emissions, analyzing the trade-off between the economic and environmental considerations. The capital cost, operating cost, and revenues for the biorefinery facilities are based on techno-economic analysis, and the proposed approach is illustrated through a case study of Minnesota, with Minneapolis-St. Paul serving as the chemicals distribution hub.

    2013-01-01

    Full Text Available The pricing problem for perishable commodities is important in manufacturing enterprise. In this study, a new model based on the profit maximization principle and a discrete demand function which is a negative binomial demand distribution is proposed. This model is used to find out the best combination for price and discount price. The computational results show that the optimal discount price equals the cost of the product. Because the demand functions which involves several different distributions is so complex that the model is hard to solve with normal numerical method. Thus we combine the model with exterior penalty function and applied a novel evolution algorithm-Imperialist Competitive Algorithm (ICA to solve the problem. Particle Swarm algorithm (PSO is also applied to solve the problem for comparison. The result shows that ICA has higher convergence rate and execution speed.

    2009-07-01

    Full Text Available The amount of cash a firm should maintain is an old problem tackled by finance literature. The recent advances in finance, mainly in the derivatives area, has opened the opportunity to revisit this subject. Cossin and Hricko (2004 studied the benefits of cash holdings using the Real Options approach. We follow their ideas extending the problem to a specific commodity producer firm in an emerging economy. We evaluate the benefits considering that raising capital takes time (timing benefit and also the benefit of avoiding the issue of securities at unfavorable moments (underpricing benefit. We use numerical procedures to solve the problem. Despite the fact that the results are not totally intuitive, we verify that the timing benefit is much more relevant than that of avoiding the underpricing benefit and that firms in emerging economies have greater advantage holding cash than those in developed economies. There is empirical evidence of this last result in the literature.

  17. Transport of solid commodities via freight pipeline: demand analysis methodology. Volume IV. First year final report

    Energy Technology Data Exchange (ETDEWEB)

    1976-07-01

    In order to determine the feasibility of intercity freight pipelines, it was necessary to determine whether sufficient traffic flows currently exist between various origins and destinations to justify consideration of a mode whose operating characteristics became competitive under conditions of high-traffic volume. An intercity origin/destination freight-flow matrix was developed for a large range of commodities from published sources. A high-freight traffic-density corridor between Chicago and New York and another between St. Louis and New York were studied. These corridors, which represented 18 cities, had single-direction flows of 16 million tons/year. If trans-shipment were allowed at each of the 18 cities, flows of up to 38 million tons/year were found in each direction. These figures did not include mineral or agricultural products. After determining that such pipeline-eligible freight-traffic volumes existed, the next step was to determine the ability of freight pipeline to penetrate such markets. Modal-split models were run on aggregate data from the 1967 Census of Transportation. Modal-split models were also run on disaggregate data specially collected for this study. The freight pipeline service characteristics were then substituted into both the aggregate and disaggregate models (truck vs. pipeline and then rail vs. pipeline) and estimates of pipeline penetration into particular STCC commodity groups were made. Based on these very preliminary results, it appears that freight pipeline has market penetration potential that is consistent with high-volume participation in the intercity freight market.

  18. Insect pollination: commodity values, trade and policy considerations using coffee as an example

    Full Text Available Science has shown the importance of animal pollinators to human food security, economy, and biodiversity conservation. Science continues to identify various factors causing pollinator declines and their implications. However, translation of the understanding of pollinators’ roles into current policy and regulation is weak and requires attention, both in developed and developing nations. The national and international trade of commodities generated via insect pollination is large. Trade in those crops could be a means of influencing regulations to promote the local existence of pollinating species, apart from their contributions to biodiversity conservation. This paper, using the example of international coffee production, reviews the value of pollinating species, and relates them to simple economics of commodity production. Recommendations are made that could influence policy and decision-making to promote coffee production, trade, and pollinators’ existence. Assumptions and considerations are raised and addressed. Although the role of insect pollinators in promoting fruit set and quality is accepted, implementing pollination conservation in forest habitats may require assured higher prices for coffee, and direct subsidies for forest conservation to prevent conversion to other crop lands. Exporting and importing governments and trade organizations could establish policy that requires insect pollination in the coffee certification process. The European Parliament and the North American Free Trade Agreement could be instrumental in creating policy and regulation that promotes insect pollination services in coffee production. The reciprocity between the services of insect pollinators in certified coffee production and their services in forest biodiversity production should be implicit in future policy negotiations to enhance both systems.

    Full Text Available  Information is essential to growing demand and maintaining efficiency throughout the supply chain for any commodity. The U.S. model for facilitating producers and first handlers having a proactive role in the flow of information about their products is through commodity checkoff programs. These industry administrated programs fund generic advertising and promotions usually through a mandatory assessment. Success of any of these programs depend on the administrative structure, the message, the ability to judge performance, and the overall equity in sharing in the program created benefits.

  4. Effects of U.S. Macroeconomic Shocks on International Commodity Prices: Emphasis on Price and Exchange Rate Pass-through Effects

    Directory of Open Access Journals (Sweden)

    Won Joong Kim

    2011-01-01

    Full Text Available Using a structural VAR with block exogeneity, diagonality and identifying restrictions, this paper analyzes: first, the macroeconomic linkages among the oil price, U.S. output, interest rate, money supply, general price level and exchange rate; and second, the relationships of the macroeconomic variables with the price indices of ten international nonfuel commodity groups. By assuming the block exogeneity of U.S. macroeconomic variables with respect to the international nonfuel commodity prices, the paper discusses how exogenous oil/macroeconomic shocks affect the international commodity prices. It finally explores which oil/macroeconomic shocks are important in explaining the variations in international commodity prices. The results show that the sources of major fluctuations in the international commodities differ greatly by commodity. Soft and hard commodity prices such as those of ‘seafood’, ‘industrial metals’, and ‘gold’ seem to be strongly affected by the financial factor. Moreover, for some commodities, price fluctuations are more affected by the financial factor than by the real factor, supporting the view of “financialization” of commodities. Those commodities include ‘vegetable oils and protein meals’, ‘meat’, ‘seafood’, and ‘industrial metals’. The financial factor is also an important source of fluctuations in the oil prices. Oil price shocks have effects on the volatilities of interest rates, money supply, and general price level instantly, as well as on the exchange rate instead of the general price two years after the shock. Over the whole forecasting horizon, the degree of exchange rate pass-through is low on the general price level but is positive and high on oil and nonfuel international commodity prices

    Harvesting, consumption and trade of bushmeat are important causes of both biodiversity loss and potential zoonotic disease emergence. In order to identify possible ways to mitigate these threats, it is essential to improve our understanding of the mechanisms by which bushmeat gets from the site of capture to the consumer's table. In this paper we highlight the previously unrecognized scale of hunting of the African straw-colored fruit bat, Eidolon helvum, a species which is important in both ecological and public health contexts, and describe the commodity chain in southern Ghana for its trade. Based on interviews with 551 Ghanaians, including bat hunters, vendors and consumers, we estimate that a minimum of 128,000 E. helvum bats are sold each year through a commodity chain stretching up to 400 km and involving multiple vendors. Unlike the general bushmeat trade in Ghana, where animals are sold in both specialized bushmeat markets and in restaurants, E. helvum is sold primarily in marketplaces; many bats are also kept by hunters for personal consumption. The offtake estimated in this paper raises serious conservation concerns, while the commodity chain identified in this study may offer possible points for management intervention. The separation of the E. helvum commodity chain from that of other bushmeat highlights the need for species-specific research in this area, particularly for bats, whose status as bushmeat is largely unknown.

    Sibley, Scott F.

    2011-01-01

    Metal supply consists of primary material from a mining operation and secondary material, which is composed of new and old scrap. Recycling, which is the use of secondary material, can contribute significantly to metal production, sometimes accounting for more than 50 percent of raw material supply. From 2001 to 2011, U.S. Geological Survey (USGS) scientists studied 26 metals to ascertain the status and magnitude of their recycling industries. The results were published in chapters A-Z of USGS Circular 1196, entitled, "Flow Studies for Recycling Metal Commodities in the United States." These metals were aluminum (chapter W), antimony (Q), beryllium (P), cadmium (O), chromium (C), cobalt (M), columbium (niobium) (I), copper (X), germanium (V), gold (A), iron and steel (G), lead (F), magnesium (E), manganese (H), mercury (U), molybdenum (L), nickel (Z), platinum (B), selenium (T), silver (N), tantalum (J), tin (K), titanium (Y), tungsten (R), vanadium (S), and zinc (D). Each metal commodity was assigned to a single year: chapters A-M have recycling data for 1998; chapters N-R and U-W have data for 2000, and chapters S, T, and X-Z have data for 2004. This 27th chapter of Circular 1196 is called AA; it includes salient data from each study described in chapters A-Z, along with an analysis of overall trends of metals recycling in the United States during 1998 through 2004 and additional up-to-date reviews of selected metal recycling industries from 1991 through 2008. In the United States for these metals in 1998, 2000, and 2004 (each metal commodity assigned to a single year), 84 million metric tons (Mt) of old scrap was generated. Unrecovered old scrap totaled 43 Mt (about 51 percent of old scrap generated, OSG), old scrap consumed was 38 Mt (about 45 percent of OSG), and net old scrap exports were 3.3 Mt (about 4 percent of OSG). Therefore, there was significant potential for increased recovery from scrap. The total old scrap supply was 88 Mt, and the overall new

  15. Substance flow analysis of parabens in Denmark complemented with a survey of presence and frequency in various commodities.

    Parabens are commonly used as preservatives due to anti-bactericidal and anti-fungicidal properties and they are ubiquitously present in personal care products, pharmaceuticals, food, industrial and domestic commodities. They are suspected of causing endocrine disrupting effects to aquatic organisms and adverse effects in humans and, thus, it is highly relevant to identify and quantify their sources and transportation pathways in the urban environment. Here a substance flow analysis (SFA) was performed in order to map and comprehend the substances' flow on a national basis. Many household commodities were found to contain parabens; cleaning detergents, slimy toys, and water-based paint. The presence and concentration of parabens are regulated in cosmetics and food. Use of parabens in pharmaceuticals as excipients is documented in Denmark. The import of parabens is increasing; although the number of industrial parabens containing commodities is decreasing and manufacturer reports phase-out of parabens. The vast majority of the paraben containing commodities has a durability of 18-30 months, thus the average lifetime of the paraben stock is perceived to be limited. The inflow was ca. 154 tonnes via pure chemicals and 7.2-73 tonnes via commodities in 2004. This corresponds to an average wastewater concentration of 640-900 microg/L, when excluding discharge to solid waste, soil, biodegradation and metabolism. This is in the same order of magnitudes as can be found in industrial wastewater but higher than that seen in domestic wastewater. The data needed for the SFA is sparse, dispersed, and difficult to access and associated with a great deal of uncertainty.

    — In 2007, the government launched a conversion program of kerosene to LPG by issuing a Presidential Regulation No. 104/2007 on Supply, Distribution and Pricing LPG 3 Kg. Article 2 on the regulation says that setting the supply, distribution, and pricing of LPG 3 Kg include planning an annual sales volume of enterprises, the reference price and the retail price and conditions of export and import of LPG 3 Kg in order to reduce subsidies Kerosene especially to divert the use of kerosene according to government policy. In principle, the purpose of this policy is to reduce energy subsidies on commodities, especially Kerosene. Although the government claimed the conversion program is success, there are few problems arising from conversion program. In 2014, many scarcity and high price of LPG 3 Kg were reported. In this case, Pertamina was given full authority to manage all supply chain and distribution. Because the root of the problem of scarcity that occurred in the supply chain system has not been explained, the proposed solutions will also be partial and not comprehensive. Thus, this research will build a structural map of the causes of supply chain system LPG 3 Kg, as well as providing a comprehensive picture of system dynamics of LPG 3 Kg supply chain system which applied in Indonesia. And the result is expected as in form of Causal Loop Diagram of supply chain system.

    2016-09-01

    Bio-electrochemical synthesis (BES) is a technique in which electro-autotrophic bacteria such as Clostridium ljungdahlii utilize electric currents as an electron source from the cathode to reduce CO2 to extracellular, multicarbon, exquisite products through autotrophic conversion. The BES of volatile fatty acids and alcohols directly from CO2 is a sustainable alternative for non-renewable, petroleum-based polymer production. This conversion of CO2 implies reduction of greenhouse gas emissions. The synthesis of heptanoic acid, heptanol, hexanoic acid and hexanol, for the first time, by Clostridium ljungdahlii was a remarkable achievement of BES. In our study, these microorganisms were cultivated on the cathode of a bio-electrochemical cell at -400 mV by a DC power supply at 37 degree Centrigrade, pH 6.8, and was studied for both batch and continuous systems. Pre-enrichment of bio-cathode enhanced the electroactivity of cells and resulted in maximizing extracellular products in less time. The main aim of the research was to investigate the impact of low-cost substrate CO2, and the longer cathode recovery range was due to bacterial reduction of CO2 to multicarbon chemical commodities with electrons driven from the cathode. Reactor design was simplified for cost-effectiveness and to enhance energy efficiencies. The Columbic recovery of ethanoic acid, ethanol, ethyl butyrate, hexanoic acid, heptanoic acid and hexanol being in excess of 80 percent proved that BES was a remarkable technology.

    Full Text Available Real-time rendering in the realm of computational fluid dynamics (CFD in particular and scientific high performance computing (HPC in general is a comparably young field of research, as the complexity of most problems with practical relevance is too high for a real-time numerical simulation. However, recent advances in HPC and the development of very efficient numerical techniques allow running first optimized numerical simulations in or near real-time, which in return requires integrated and optimized visualization techniques that do not affect performance. In this contribution, we present concepts, implementation details and several application examples of a minimally-invasive, efficient visualization tool for the interactive monitoring of 2D and 3D turbulent flow simulations on commodity hardware. The numerical simulations are conducted with ELBE, an efficient lattice Boltzmann environment based on NVIDIA CUDA (Compute Unified Device Architecture, which provides optimized numerical kernels for 2D and 3D computational fluid dynamics with fluid-structure interactions and turbulence.

  1. A New Method for Setting Futures Portfolios’ Maintenance Margins: Evidence from Chinese Commodity Futures Markets

    Directory of Open Access Journals (Sweden)

    Chi Xie

    2014-01-01

    Full Text Available The Chinese commodity futures markets neglect the existence of the risk hedge and diversification between futures contracts, thus leading to overcharge futures portfolio holders’ maintenance margins. To this end, this paper proposes a new method, namely, the multivariate t-Copula-POT-PSRM method, which combines three models, that is, the multivariate t-Copula, the peaks over threshold (POT, and the power spectral risk measures (PSRM, to set futures portfolios’ maintenance margins. In the empirical analysis, we first construct four kinds of futures portfolios and set their maintenance margins by using the new method. Then, we introduce two evaluation indicators, namely, the prudence index (PI and the opportunity cost index (OCI, to assess the effectiveness of the proposed method. We also compare the outcomes of the two evaluation indicators of the new method with those of the widely used linear additive model. The empirical results show that the new method can, respectively, lower the OCI value of all four kinds of futures portfolios for the In-sample period and the Out-of-sample period without significantly reducing the PI value as against the traditional model, which implies that the proposed method can be used to balance security and investment efficiency in the futures market.

  2. Market Efficiency and the Risks and Returns of Dynamic Trading Strategies with Commodity Futures

    Science.gov (United States)

    Switzer, Lorne N.; Jiang, Hui

    This paper investigates relationships between profits from dynamic trading strategies, risk premium, convenience yields, and net hedging pressures for commodity futures. As a market efficiency study, it crosses a number of disciplines, including traditional finance, behavioral finance, and behavioral psychology. The term structure of oil, gold, copper and soybeans futures markets contains predictive power for the corresponding term premium. However, only oil futures and soybean futures lead their spot premium. Significant momentum profits are identified in both outright futures and spread trading strategies when the spot premium and the term premium are used to form winner and loser portfolios. Profits from active strategies based on winner and loser portfolios are conditioned on market structure and net hedging pressure effects. Dynamic trading strategies based on contracts with extreme backwardation, extreme contango, and extreme hedging pressures are also tested. On average, spread trading outperforms outright futures trading in capturing the term structure risk and hedging pressure risk. For such strategies, long-short the long-term spread offers the greatest and most significant return and it offers the only exploitable trading profits built on the past hedging pressure. The existence of profits from active trading strategies based on winners is consistent with behavioral finance and behavioral psychology models in which market participants irrationally overreact to information and trends.

    Full Text Available This article situates, elaborates, and further explains the theory of global value chain (GVC governance developed by Gereffi, Humphrey and Sturgeon (2005. The theory of GVC governance at the center of the paper is part of a long-term effort to generalize from accumulated comparative observational research on a range of global industries. First, I discuss the motivations for supplementing the buyer-driven and producer-driven modes of global commodity chain governance developed by Gary Gereffi in the 1990s with an industry-neutral, non-empirical framework. Second, I briefly present the features of the GVC governance framework as they appear in the 2005 article. Third, I discuss the interdisciplinary theoretical underpinnings of the framework in more detail than was possible in the original article. Fourth, I discuss the problem of variation in GVC governance. Fifth, I situate the GVC governance framework in a larger field of GVC-related theory, including but not limited to power and institutions.

    We describe a storage system that removes I/O bottlenecks to achieve more than one million IOPS based on a user-space file abstraction for arrays of commodity SSDs. The file abstraction refactors I/O scheduling and placement for extreme parallelism and non-uniform memory and I/O. The system includes a set-associative, parallel page cache in the user space. We redesign page caching to eliminate CPU overhead and lock-contention in non-uniform memory architecture machines. We evaluate our design on a 32 core NUMA machine with four, eight-core processors. Experiments show that our design delivers 1.23 million 512-byte read IOPS. The page cache realizes the scalable IOPS of Linux asynchronous I/O (AIO) and increases user-perceived I/O performance linearly with cache hit rates. The parallel, set-associative cache matches the cache hit rates of the global Linux page cache under real workloads.

Therefore, to meet the interests of industry and consumers, the best way is the expansion of the new plant. And to support the expansion of the factory in the country, clearly requires a major investment. Based on the assumptions above, Holcim as a newbie in the national cement market, which previously bought cement Cibinong also takes part in the national market. Now, Holcim is not half-hearted continuously expanding its new factory in Tuban to increase the strength of its two plants that are already running.

    In a highly interdependent economic world, the nature of relationships between financial entities is becoming an increasingly important area of study. Recently, many studies have shown the usefulness of minimal spanning trees (MST) in extracting interactions between financial entities. Here, we propose a modified MST network whose metric distance is defined in terms of cross-correlation coefficient absolute values, enabling the connections between anticorrelated entities to manifest properly. We investigate 69 daily time series, comprising three types of financial assets: 28 stock market indicators, 21 currency futures, and 20 commodity futures. We show that though the resulting MST network evolves over time, the financial assets of similar type tend to have connections which are stable over time. In addition, we find a characteristic time lag between the volatility time series of the stock market indicators and those of the EU CO2 emission allowance (EUA) and crude oil futures (WTI). This time lag is given by the peak of the cross-correlation function of the volatility time series EUA (or WTI) with that of the stock market indicators, and is markedly different (>20 days) from 0, showing that the volatility of stock market indicators today can predict the volatility of EU emissions allowances and of crude oil in the near future.

    @@ Recently, two industrial standards for inspection and quarantine, including the Requirements on Food Safety Control System and the Guide to Examination & Verification of Food Safety Control System drafted by the joint efforts of Certification and Accreditation Administration of the People's Republic of China (CNCA), China Import & Export Commodity Inspection Technology Institute and Hebei Inspection & Quarantine Bureau, passed examination and approval. The attending experts believed that these two standards have filled China's gaps respectively in the control of food safety as well as in the examination and inspection of safety control system.

  9. GDP AS THE INDICATOR OF LIVING STANDARDS: THE ANTICIPATION

    Directory of Open Access Journals (Sweden)

    Mr. Maxim V. Klymas

    2016-09-01

    Full Text Available Every state is interested in improving the quality of life of the population. One of the indicators reflecting the living standards is GDP of the country in its general understanding, and in per capita terms. Therefore, increasing the country's GDP is the main goal of any state. GDP growth is limited by many factors. In developing countries with export-oriented and commodity-based economy the main factor is the price of resources in international market prices and the central rate. In this article, we addressed the issue of Russia's GDP, depending on oil prices, as well as the impact of exchange rate of the US dollar to the Russian Federation rouble. We tried to answer the question whether Russia's economy is export-oriented at the commodity sector, and whether it is possible to grow GDP excluding exchange rates.

    Full Text Available In accordance with Article 6 of Regulation (EC No 396/2005, Italy, herewith referred to as the evaluating Member State (EMS, received an application from BASF Italia Srl. to modify the existing MRLs for metaflumizone in various crops. In order to accommodate for the intended uses of metaflumizone in Europe, Italy proposed to raise the existing MRLs for all the crops under consideration, except for pepper, head cabbage, Brussels sprouts, lettuce, scarole, melon and watermelon as well as to raise MRLs for several animal commodities. According to EFSA, the data are sufficient to derive MRL proposals for all crops under consideration, except for melons, watermelons, herbs and salad plants (except lettuce. For peppers, Brussels sprouts and head cabbage no need to modify the existing MRL was identified.. The new intended use on cotton seed will not affect the existing livestock dietary burden and thus the potential carry-over of metaflumizone residues into food of animal origin was not further investigated. According to risk assessment results, acute consumer intake concerns cannot be excluded for residues in scarole and lettuce from indoor use and in broccoli from SEU use. The less critical NEU use on broccoli and lettuce and intended uses of metaflumizone on other crops under consideration will not result in consumer intake concerns. However, in case residues of metaflumizone occur in lettuce, broccoli and Chinese cabbage at the derived MRL value, acute consumer intake concerns cannot be excluded. Risk managers should decide whether the safety margin of the exposure assessment based on the highest residue is sufficient, considering that in reality residues at the proposed MRL might occur.

  13. Cars, corporations, and commodities: consequences for the social determinants of health.

    Science.gov (United States)

    Woodcock, James; Aldred, Rachel

    2008-02-21

    Social epidemiologists have drawn attention to health inequalities as avoidable and inequitable, encouraging thinking beyond proximal risk factors to the causes of the causes. However, key debates remain unresolved including the contribution of material and psychosocial pathways to health inequalities. Tools to operationalise social factors have not developed in tandem with conceptual frameworks, and research has often remained focused on the disadvantaged rather than on forces shaping population health across the distribution. Using the example of transport, we argue that closer attention to social processes (capital accumulation and motorisation) and social forms (commodity, corporation, and car) offers a way forward. Corporations tied to the car, primarily oil and vehicle manufacturers, are central to the world economy. Key drivers in establishing this hegemony are the threat of violence from motor vehicles and the creation of distance through the restructuring of place. Transport matters for epidemiology because the growth of mass car ownership is environmentally unsustainable and affects population health through a myriad of pathways. Starting from social forms and processes, rather than their embodiment as individual health outcomes and inequalities, makes visible connections between road traffic injuries, obesity, climate change, underdevelopment of oil producing countries, and the huge opportunity cost of the car economy. Methodological implications include a movement-based understanding of how place affects health and a process-orientated integration of material and psychosocial explanations that, while materially based, contests assumptions of automatic benefits from economic growth. Finally, we identify car and oil corporations as anti-health forces and suggest collaboration with them creates conflicts of interest.

    2015-01-01

    Full Text Available This paper looks at Gottfried Semper’s notions on the commodity and capitalism. When Semper attended the Great Exhibition, he realized the enormous impact that capitalist industries and interests have had on the arts. The Crystal Palace has always been at the centre of Semper scholarship but the focus has been less on capitalism than on the arts and crafts although Semper’s comments on capitalism are apparent and illustrate that he understood that everything becomes a commodity, even architecture. As a theorist trying to principles of by which art is driven, he analyzes industries and their mass produced objects and tries to come to terms with this. At the same time, he tries to integrate capitalism into his historical and scientific models. This paper tries to unravel Semper’s ideas on capitalism and the way he tries to resolve its problems in artistic production.

  15. Consumer behaviour when buying private commodities: Heating systems; Verbraucherverhalten beim Kauf eines privaten Gebrauchsguts am Beispiel Heizung

    Energy Technology Data Exchange (ETDEWEB)

    Decker, Thomas Anton

    2010-07-01

    The publication intends to explain the reasons why consumers buy a private commodity. The focus is on the main reasons for buying the commodity. These were comparatively evaluated in order to find out which of the reasons have the biggest effect and which ones are of lesser importance. As an example, the acquisition of a heating system was chosen. The brand of heating system was neglected in favour of the product type ('oil heating system', 'gas heating system', 'pellets heating system', 'heat pump'). As the acquisition of a heating system is an extensive buying decision, primarily cognitive explanation determinants were used in this investigation. For an analysis of the reasons for buying, a model was developed on the basis of theoretical considerations and then tested empirically.

  16. Domestic wash water reclamation for reuse as commode water supply using filtration: Reverse-osmosis separation technique

    Science.gov (United States)

    Hall, J. B., Jr.; Batten, C. E.; Wilkins, J. R.

    1974-01-01

    A combined filtration-reverse-osmosis water recovery system has been evaluated to determine its capability to reclaim domestic wash water for reuse as a commode water supply. The system produced water that met all chemical and physical requirements established by the U.S. Public Health Service for drinking water with the exception of carbon chloroform extractables, methylene blue active substances, and phenols. It is thought that this water is of sufficient quality to be reused as commode supply water. The feasibility of using a combined filtration and reverse-osmosis technique for reclaiming domestic wash water has been established. The use of such a technique for wash-water recovery will require a maintenance filter to remove solid materials including those less than 1 micron in size from the wash water. The reverse-osmosis module, if sufficiently protected from plugging, is an attractive low-energy technique for removing contaminants from domestic wash water.

    This study examines the characteristics and behaviour of key commodity/product markets and market institutions in Africa and their consequences for economic growth. Their contribution to economic growth appears to have been limited by high transaction costs and weak institutions. Government heavy intervention, persistent shortages of market infrastructure and lack of effective market information system, all contribute to the seemingly high transaction costs in these markets.

  1. Trading forests: land-use change and carbon emissions embodied in production and exports of forest-risk commodities

    Science.gov (United States)

    Henders, Sabine; Persson, U. Martin; Kastner, Thomas

    2015-12-01

    Production of commercial agricultural commodities for domestic and foreign markets is increasingly driving land clearing in tropical regions, creating links and feedback effects between geographically separated consumption and production locations. Such teleconnections are commonly studied through calculating consumption footprints and quantifying environmental impacts embodied in trade flows, e.g., virtual water and land, biomass, or greenhouse gas emissions. The extent to which land-use change (LUC) and associated carbon emissions are embodied in the production and export of agricultural commodities has been less studied. Here we quantify tropical deforestation area and carbon emissions from LUC induced by the production and the export of four commodities (beef, soybeans, palm oil, and wood products) in seven countries with high deforestation rates (Argentina, Bolivia, Brazil, Paraguay, Indonesia, Malaysia, and Papua New Guinea). We show that in the period 2000-2011, the production of the four analyzed commodities in our seven case countries was responsible for 40% of total tropical deforestation and resulting carbon losses. Over a third of these impacts was embodied in exports in 2011, up from a fifth in 2000. This trend highlights the growing influence of global markets in deforestation dynamics. Main flows of embodied LUC are Latin American beef and soybean exports to markets in Europe, China, the former Soviet bloc, the Middle East and Northern Africa, whereas embodied emission flows are dominated by Southeast Asian exports of palm oil and wood products to consumers in China, India and the rest of Asia, as well as to the European Union. Our findings illustrate the growing role that global consumers play in tropical LUC trajectories and highlight the need for demand-side policies covering whole supply chains. We also discuss the limitations of such demand-side measures and call for a combination of supply- and demand-side policies to effectively limit tropical

  2. Reasoned opinion on the modification of the existing MRLs for captan in pome fruits and commodities of animal origin

    Directory of Open Access Journals (Sweden)

    European Food Safety Authority

    2013-07-01

    Full Text Available In accordance with Article 6 of Regulation (EC No 396/2005, France received an application to modify the existing MRLs for captan in pome fruits and in commodities of animal origin. In order to accommodate the intended use, France proposed raising the existing MRLs for pome fruit, ruminant tissues and milk. According to EFSA, the data are sufficient to derive a MRL proposal for the SEU and the NEU use on pome fruit, according to the residue definition “sum of captan and THPI, expressed as captan” and for the residue definition “sum of captan and folpet”. The nature of captan residues in livestock is sufficiently elucidated and EFSA proposes to modify the existing residue definitions in animal commodities according to the conclusions of the peer review. The results of the feeding study indicate that in order to accommodate the SEU use of captan on pome fruit, the MRLs for ruminant meat, liver and kidney would have to be amended. For the less critical NEU use on pome fruit, MRLs at the LOQ are sufficient for commodities of animal origin. Based on the results of the consumer risk assessment EFSA concludes that the NEU use of captan on pome fruit and resulting residues in commodities of animal origin will not pose a public health concern. No consumer health risk was identified also for the MRL proposals derived for the more critical SEU use. However, in case apples and pears contain residues at the level of the MRL proposal for the SEU use, the safety margin for acute exposure was found to be very narrow. Therefore EFSA would recommend setting the MRLs for apple and pear on the basis of the NEU data set.

  5. An industry perspective on the use of seasonal forecasts and weather information for evaluating sensitivities in traded commodity supply chains

    Science.gov (United States)

    Domeisen, Daniela; Slavov, Georgi

    2015-04-01

    Weather information on seasonal timescales is crucial to various end users, from the level of subsistence farming to the government level. Also the financial industry is ever more aware of and interested in the benefits that early and correctly interpreted forecast information provides. Straight forward and often cited applications include the estimation of rainfall and temperature anomalies for drought - prone agricultural areas producing traded commodities, as well as some of the rather direct impacts of weather on energy production. Governments, weather services, as well as both academia and private companies are working on tailoring climate and weather information to a growing number of customers. However, also other large markets, such as coal, iron ore, and gas, are crucially dependent on seasonal weather information and forecasts, while the needs are again very dependent on the direction of the predicted signal. So far, relatively few providers in climate services address these industries. All of these commodities show a strong seasonal and weather dependence, and an unusual winter or summer can crucially impact their demand and supply. To name a few impacts, gas is crucially driven by heating demand, iron ore excavation is dependent on the available water resources, and coal mining is dependent on winter temperatures and rainfall. This contribution will illustrate and provide an inside view of the type of climate and weather information needed for the various large commodity industries.

    Full Text Available The economic objective of the modern high-tech enterprise is the optimal expansion of its own market niche and bringing the production capacities in accordance with the current demand for the products. An important role in this respect is played by issues of optimal organization of the enterprise logistics, marketing analysis of the current demand and effective advertising campaign aimed at maximal use of the available production capacity and creation of proper conditions for developing, in particular for increasing the production capacities. The purpose of the article is the elaboration of economic and mathematical models of enterprise production activity taking into account the logistics and market demand; the use of the elaborated model to harmonize the rate of production of everyday commodities with the rate of their disposal. Two variants of the enterprise logistics schemes are analyzed. The influence of the advertising company on expanding the enterprise market niche is studied. A model that allows conducting a detailed study of the influence of market conditions on the pace of sales has been developed. It is appropriate to apply the model for the integrated coordination of the production rate of commodities of everyday demand with the dynamics of flows of commodities and services disposal.

  8. Two Islands, One Commodity: Cuba, Java, and the Global Sugar Trade (1790-1930

    Directory of Open Access Journals (Sweden)

    Jonathan Curry-Machado

    2012-12-01

    Full Text Available Sugar had become, by the eighteenth century, a global commodity. Originating in East Asia, plantations in the Americas fed the growing taste for its use in Europe, with its consumption increasingly popularised. The 1791 Revolution in Saint Domingue (Haiti and the 1807 British abolition of the slave trade prompted shifts in the epicentres of sugar, the most important of these being arguably to Cuba and Java. These two fertile islands saw the burgeoning development of sugar-plantation systems with major inputs of foreign capital and forced labour. In the process the two islands each, respectively, became central to the very much truncated Spanish and Dutch colonial empires left after the Napoleonic wars and the Latin American wars of liberation; and by the mid-nineteenth century in the case of Cuba, and by the late nineteenth century in the case of Java, they had been catapulted to global sugar pre-eminence. There has been an abundance of study on the two islands each in their own right, but none systematically examines their parallel trajectories. Yet the question arises as to how sugar came to dominate the agriculture, industry and trade of these two islands; and how these two islands in particular, in two different colonial systems and parts of the world, should rise to sugar pre-eminence in the way they did and when they did. Are there connections and similarities between the two that help explain this phenomenon? This article analyses the conditions that led Java and Cuba to become the prime cane-sugar exporters of the nineteenth and early twentieth centuries. Initiative for this came from the linkages between their dominant elites and the transnational, transimperial networks of trade and capital. This furthered the stimulation of technological and scientific innovation in both, enabled not only through the introduction of the latest advances in machinery and method, but also the immigration of technical skilled workers from Europe and North

  9. Journal standards.

    Science.gov (United States)

    Jackson, R

    2003-08-01

    Despite its many imperfections, the peer review process is a firmly established quality control system for scientific literature. It gives readers some assurance that the work and views that are reported meet standards that are acceptable to a journal. Maureen Revington's editorial in a recent issue of the Australian Veterinary Journal (Revington2002) gives a good concise warts and all overview of the process and is well worth reading. I have some concerns about several articles in the December 2002 issue of the New Zealand Veterinary Journal (Volume 50, Number 6), devoted to the health and welfare of farmed deer, that relate to extensive citing of non-peer reviewed papers. I can understand the need for information to flow from researchers to the wider community but that need is already satisfied by publications such as the proceedings of the Deer Branch of the New Zealand Veterinary Association and Proceedings of the New Zealand Society of Animal Production. Non-peer reviewed papers have been cited in the Journal in the past but never to the extent displayed in this particular issue. It degrades the peer-review process and creates an added burden for reviewers who are forced to grapple with the uncertainties of the science in non-peer reviewed citations. One of my fears is that this process allows science from non peer reviewed articles to be legitimised by its inclusion in a peer reviewed journal and perhaps go on to be accepted as dogma. This is a real danger given the difficulties associated with tracing back to original citations and the increasing volume of scientific literature. It also affords opportunities for agencies to pick up questionable and doubtful science and tout it as support for their products or particular points of view. If deer researchers choose to publish most of their work in proceedings then so be it. However this approach, which seems to becoming increasingly prevalent in the deer sector, is questionable from an established science point

  12. Essays on Commodity Prices and Macroeconomic Performance of Developing and Resources Rich Economies: Evidence from Kazakhstan

    Science.gov (United States)

    Bilgin, Ferhat I.

    My dissertation consists of three essays in empirical macroeconomics. The objective of this research is to use rigorous time-series econometric analysis to investigate the impact of commodity prices on macroeconomic performance of a small, developing and resource-rich country, which is in the process of transition from a purely command and control economy to a market oriented one. Essay 1 studies the relationship between Kazakhstan's GDP, total government expenditure, real effective exchange rate and the world oil price. Specifically, I use the cointegrated vector autoregression (CVAR) and error correction modeling (ECM) approach to identify the long and short-run relations that may exist among these macroeconomic variables. I found a long-run relationship for Kazakhstan's GDP, which depends on government spending and the oil price positively, and on the real effective exchange rate negatively. In the short run, the growth rate of GDP depends on the growth rates of the oil price, investment and the magnitude of the deviation from the long-run equilibrium. Essay 2 studies the inflation process in Kazakhstan based on the analysis of price formation in the following sectors: monetary, external, labor and goods and services. The modeling is conducted from two different perspectives: the first is the monetary model of inflation framework and the second is the mark-up modeling framework. Encompassing test results show that the mark-up model performs better than the monetary model in explaining inflation in Kazakhstan. According to the mark-up inflation model, in the long run, the price level is positively related to unit labor costs, import prices and government administered prices as well the world oil prices. In the short run, the inflation is positively influenced by the previous quarter's inflation, the contemporaneous changes in the government administered prices, oil prices and by the changes of contemporaneous and lagged unit labor costs, and negatively affected

  13. The PCA and IOA approaches for life-cycle analysis of greenhouse gas emissions from Thai commodities and energy consumption

    Pawinee Suksuntornsiri

    2005-01-01

    Full Text Available The use of more substitutable commodities, selected by their total greenhouse gas (GHG emissions would highly contribute to mitigating the effects of global warming. Life-cycle analysis (LCA is a solution that can evaluate the total emissions from a lifetime production of a commodity. It is widely applied to reveal the actual environmental emissions in many countries, however this data could not be applied in other countries due to different emission and energy consumption structures. LCA emission factors within the same country are also different due to different assumptions on the boundary and lifetime of a considered production process. The process chains analysis (PCA, the conventional LCA approach which is mostly applied in Thailand, is accurate in the direct production process, but its analysis in the higher order production process is usually truncated due to a lack of data. It is laborious, time consuming, and hard to gather all the data from the whole production process. This article presents the pros and cons of PCA and inputoutput analysis (IOA and introduces an appropriate approach in a Thai context. The adaptation of energyrelated GHG emissions findings in the revised 1996 Intergovernmental Panel on Climate Change (IPCC guidelines for national GHG inventories are introduced for a commodity emission factor and traced through the whole production chains by IOA. In conclusion, the IOA gives emissions in average values and the historical economic structure is used to derive the emissions. However, emissions from every single link of production lifecycle can be taken into account. A combined PCA and IOA is recommended for an LCA of GHG emissions in Thailand.

    Full Text Available In accordance with Article 6 of Regulation (EC No 396/2005, United Kingdom received an application from BASF to modify the existing MRLs for the active substance mepiquat in oats, wheat and food commodities of animal origin. In order to accommodate the intended uses of mepiquat, United Kingdom proposed to raise the existing MRLs from the limit of quantification to 0.1 mg/kg for meat (except poultry meat, to 0.5 mg/kg for liver (except poultry liver, to 0.8 mg/kg for kidney and offal (except poultry kidney and offal, and from 2 mg/kg to 3 mg/kg for oats and wheat. United Kingdom drafted an evaluation report in accordance with Article 8 of Regulation (EC No 396/2005, which was submitted to the European Commission and forwarded to EFSA. EFSA considers that the submitted supervised residue trials are sufficient to derive MRL proposals of 3 mg/kg for the proposed uses on wheat (existing and new residue definition; for oats the MRL does not have to be modified for the existing residue definition, but needs to be raised to 3 mg/kg for the new residue definition. Adequate analytical enforcement methods are available to control the residues of mepiquat in dry content commodities (oat and wheat under consideration at the validated LOQ of 0.05 mg/kg. For certain food commodities of animal origin the MRLs have to be modified as well. Based on the risk assessment results, EFSA concludes that the proposed use of mepiquat on oats and wheat and the resulting residues in food of animal origin will not result in a consumer exposure exceeding the toxicological reference values and therefore is unlikely to pose a consumer health risk.

    Full Text Available Introduction: Fruit and nuts, all kinds of vegetables, legumes and vegetable products, including commodity baskets with high proportion of nutritive value, are of great importance for policymakers of the agricultural sector. Therefore, the study of the conditions and factors affecting the demand for these goods can be predisposing advice to control the market and other factors affecting their use. But when it comes to the country at macro level of household demand, the aggregate commodity group beomes important. In cases where it is necessary to apply the fruits or vegetables as a function of household aggregation of a group of goods to be estimated, it is necessary a group of products with the scientific method to get aggregate and form a group variable as fruits or vegetables are included in the econometric model. Therefore, due to problems such as lack of access to information on each product separately, the high cost of collecting the data, missing observations, multicollinearity problem and limited degrees of freedom, we have to use grouping and composite commodities. But it is important that the correct grouping and consistent is made because of incorrect Aggregation, as specified in the error term appears on demand system estimated and Lead to biased estimation of the values of parameters and elasticity's, Which results in an incorrect picture of consumer behavior. Study of composite conditions of Agricultural commodities, as an important topic in economics, had been considered. Because mostly, access to disaggregate of the goods is not possible, and other problems such as multicollinearity occurs by examining the separation in the econometrics model. Study of composite conditions of Agricultural commodities, as an important topic in economics, had been considered. Due to its importance in the study, condition of Aggregation fruit and nuts, all kinds of vegetables and Bean (legumes are using Generalized Composite Commodity Theorem (GCCT

    Vicente Celestino Pires Silveira

    Full Text Available ABSTRACT: At the end of the 20th and early 21st century, agricultural systems incorporated definitively a new mission: to generate goods for a world population that continues to grow and whose way of life demand food with low environmental impact. Soybean is the main raw material for the production of biodiesel in Brazil, accountably responsible for 82.4% of the total produced between 2006 and 2013. The Brazilian state of Rio Grande do Sul (RS, which is formed by the Pampa and the Atlantic forest biomes, was responsible for 35.7% of the country's biodiesel production in the referred period. The aim of this paper was to verify the impact of the increased area of soybean cultivation in land use in Rio Grande do Sul State, in the period between 1990 and 2015, considering separately its two biomes (Pampa and Atlantic Forest original areas, using both census dataset and satellite images. We used the period from 1990 to 2000 as before commodity rising price (BCRP and the period from 2000 to 2013 as commodity rising price (CRP. The 505,162 ha from Atlantic Forest biome and 1,192,115ha from Pampa biome were added to soybean production in the CRP period. In the Atlantic Forest, this enlargement occurred in the border of the main production area, while in Pampa biome conversion of natural grassland to crop land was the main reason for the large increment in the cultivated area.

    This paper reported the occurrence and concentrations of macrocyclic-, polycyclic- and nitro musks in cosmetics and household commodities collected from Japan. The high concentrations and detection frequencies of Musk T, habanolide, and exaltolides were found in commercial products, suggesting their large amounts of production and usage in Japan. Polycyclic musks, HHCB and OTNE, also showed high concentrations in cosmetics and products. The estimated dairy intakes of Musk T and HHCB by the dermal exposure to commercial products were 7.8 and 7.9 μg/kg/day in human, respectively, and perfume and body lotion are dominant exposure sources. We also analyzed synthetic musks in house dusts. Polycyclic musks, HHCB and OTNE, showed high concentrations in samples, but macrocyclic musks were detected only in a few samples, although these types of musks were highly detected in commercial products. This is probably due to easy-degradation of macrocyclic musks in indoor environment. The dairy intakes of HHCB by dust ingestions were 0.22 ng/kg/day in human, which were approximately five orders of magnitudes lower than those of dermal absorption from commercial household commodities.

    Diversion of commodities from their intended use to an unintended use, e.g., when commodities intended for consumption are used as seed for planting, is an important issue in agricultural trade that has implications for the establishment of pests and pathogens in an importing country and for the appropriate strength of plant health measures. Consequently, understanding and accurately characterizing the risk of diversion from intended use is highly relevant to policymakers, trading partners, and in trade dispute arbitration. To our knowledge, no risk assessments have ever accounted for the likelihood of diversion from intended use. Here we present an approach to analyzing this risk using diversion of U.S. table stock potatoes to seed for planting by Mexican potato producers as a case study. We use probabilistic pathway models to characterize the movement of white, yellow, and russet potatoes from the United States into Mexico at current and double export volumes. We then model the likelihood of these potatoes being diverted for seed and the subsequent establishment of bacteria, nematode, and virus pests in Mexico. Our approach demonstrates how diversion from intended use can be quantified in one scenario and, in particular, how it can be analyzed to estimate the magnitude of diversion required to produce a high risk of pest establishment.

    Analogues of the Alternaria mycotoxin tenuazonic acid (TA, biosynthesized by the fungus from the amino acid isoleucine) derived from valine (ValTA), leucine (LeuTA), alanine (AlaTA) and phenylalanine (PheTA) were synthesized and characterized by mass spectrometry (MS) and (1)H nuclear magnetic resonance (NMR) spectroscopy. Concentrations of stock solutions were determined by quantitative (1)H NMR (qHNMR). Two analytical methods based on high performance liquid chromatography (HPLC) and MS detection were developed, one with derivatization with 2,4-dinitrophenylhydrazine (DNPH) and one without derivatization. Limits of detection (LODs) were between 1-3 μg/kg (with derivatization) and 50-80 μg/kg (without derivatization). Respective limits of quantitation (LOQs) were about three times higher. Beside TA, the analogues LeuTA (about 4% of TA content) and ValTA (about 10% of TA content) were found in highly contaminated sorghum infant cereals and sorghum grains. Other analogues were not detected. Quantification of LeuTA and ValTA was performed using [(13)C6,(15)N]-TA as internal standard and matrix matched calibration. Recovery was between 95±11% and 102±10% for both compounds. Precision (relative standard deviation of triplicate sorghum cereal analyses three times during 3 weeks) was 7% for TA (912±60 μg/kg), 17% for LeuTA (43±8 μg/kg) and 19% for ValTA (118±22 μg/kg). These results indicate that several TA-like compounds, which are not yet characterized in aspects of their toxic properties, were detected in sorghum based infant food highly contaminated with TA, already.

    Full Text Available With the constant changes of the market demand trends and modern information technology which greatly influence supply chain operation and management, postponement has been developed to be an important strategy in some of the supply chain processes. This paper studies the multi-period and multi-commodity flow supply chain network equilibrium problem with postponement strategy under a type of supply chain management pattern. Taking the influences of the relationship between orders and inventory management of supply chain into consideration, and employing variational inequality to establish multi-period equilibrium model at each level and network equilibrium model , this paper eventually works out the conditions to make the system achieve equilibrium, and also offers economic interpretation with concrete examples to verify them.

The paper analyses the European wheat futures markets (feed and milling and the Chicago Board of Trade’s wheat contract as a comparison. Although the main purpose of the paper is to analyse whether futures markets are still useful for hedging (considering the demands from different market participants, implicitly this can be seen as testing whether the increasing presence of speculation has made futures markets divorced from physical markets. The results indicate that hedging with futures markets is still a viable alternative for dealing with price risk. This is particularly true in short period hedges (e.g. merchants and processors, where the basis seems to have been affected by the observed price instability.

  12. Comparing Critical Capitalist Commodity Chains in the Early Twenty-first Century: Opportunities For and Constraints on Labor and Political Movements

    Directory of Open Access Journals (Sweden)

    Elizabeth Sowers

    2015-08-01

    Full Text Available There have been a number of critical historical opportunities for labor to exert power by interrupting long distance flows of commodities at the extraction, processing, and transport stages. This vulnerability has been used by workers in these industries to gain higher wages and better working conditions and to achieve political goals in national and international arenas. In this paper, we compare two commodity chains that are critical components of the global economy. The first, which we describe as transport, is a broad category involving a range of manufactured goods, whose delivery to customers around the world was fundamentally changed in the past fifty years via "containerization" and "the logistics revolution." The second is oil and gas, which also has experienced recently dramatic changes in both extraction (via "tar sands" and "[racking" and transportation. In each case, we discuss possibilities and challenges for labor and political organizing to disrupt capital in these key commodity chains. We identify the "stakes" in each commodity chain by demonstrating the vulnerabilities on which labor and political organizations/movements could capitalize, which usually stem from the capital intensity and global integration of each critical commodity chain. These vulnerabilities are the factors which form the most basic opportunities for organizing in these sectors. Our analysis further suggests that while transport and raw materials remain vulnerable nodes in capitalist commodity chains, there are also constraints and challenges to be faced by labor and social movement organizations (SMOs that might attempt to leverage power over these circuits of the world-economy.

  13. Reasoned opinion on the modification of the existing MRLs for aminopyralid in food commodities of animal origin

    Directory of Open Access Journals (Sweden)

    European Food Safety Authority

    2013-06-01

    Full Text Available In accordance with Article 6 of Regulation (EC No 396/2005, the United Kingdom received an application from Dow AgroSciences Ltd. to modify the existing MRLs for aminopyralid in food derived from ruminants in order to account for residues which occur in these commodities when livestock is fed with grass treated with aminopyralid according to the authorized GAPs in the United States, Canada, Bolivia, Argentina and Brazil. The EMS proposed to raise the existing MRLs for aminopyralid in ruminant meat, fat, liver, kidney and milk. The metabolism of aminopyralid has been elucidated in lactating goats and poultry. Parent aminopyralid is proposed as residue definition for enforcement and risk assessment for all products of animal origin. The residue levels in the imported food of animal origin should reflect livestock exposure from the intake of all feed crops treated with aminopyralid in the country of origin. Since EFSA does not have a comprehensive overview of the feeding practices and the aminopyralid residues in feed available in these countries, it is more appropriate to calculate the dietary burden on an international level, using internationally agreed methodologies. Thus, livestock dietary burden calculated by the JMPR was used to estimate the potential carry-over of residues into food of animal origin. Data from feeding studies indicate that the existing EU MRLs have to be raised for ruminant meat, fat, kidney and liver. For milk, eggs, poultry and swine products no modification of the existing EU MRLs is required. Based on the risk assessment results, EFSA concludes that residues in food commodities of animal origin from the use of aminopyralid on grass in third countries and the resulting MRL proposals will not result in a consumer exposure exceeding the toxicological reference values and therefore is unlikely to pose a public health concern.

  14. Globalisations in a nutshell: Historical perspectives on the changing governance of the shea commodity chain in northern Ghana

    Directory of Open Access Journals (Sweden)

    Andrew Wardell

    2013-08-01

    Full Text Available Pre-colonial patterns of trade in West Africa included exchanges of shea in periodic local and regional markets. The collection, processing and marketing of shea products in such markets continues to be predominantly by women to both meet subsistence needs, and exchange of surpluses. In the early part of the 20th century, the British colonial administration considered the possibilities of starting large-scale exports of shea kernels to Europe. Multiple colonial initiatives to develop the global trade were not successful due to a composite of factors. Contemporary patterns of production, trade and regulation are contrasted in the context of globalisation in the post-independence era. The government of Ghana has progressively reinforced its ambitions to expand the shea nut trade as part of the state’s portfolio of major non-traditional agricultural export commodities. This policy is embedded within the (now dominant orthodoxy of neo-liberalism, which privileges monetized production systems and private over public regulation. Historically and culturally-embedded patterns of shea production and trade by women in northern Ghana may now be challenged by the emergence of new processing technologies, the emergence of an oligopolistic global commodity chain and the anticipated continued growth in global demand for cocoa butter equivalents.  Nevertheless, the cumulative impacts of increasing commercialisation and world market integration at the national and local level in Ghana, and other West African producer countries, are still unknown. There are risks, however, that this process may result in social differentiation, changes in household consumption patterns and loss of livelihoods, particularly for women.

    Several insects that act as vectors, including houseflies (Musca domestica L.), are often considered to be an important source of fungal contamination in human foods. Houseflies are also involved in the transmission of bacterial pathogens that may pose a serious hazard to human health. Thus, the rural population of South Africa, as typified by that in the Gauteng Province investigated in this study, is at high risk from fungal exposure disseminated by houseflies and it is therefore important to assess the role of flies in contaminating various food commodities. Eighty four samples of houseflies (captured from households and pit toilets) were studied for their potential to carry fungal spores into food commodities. The fungi occurring in samples of raw maize (15) and porridge (19) were also assessed. Fungal isolates were identified based on morphological characteristics by conventional identification methods. Fifteen genera of fungi were isolated and identified, of which Aspergillus, Fusarium, Penicillium, Cladosporium, Moniliella and Mucor were the most prevalent in all three sample types analysed. The incidence rates of fungal contamination per total fungal count isolated in houseflies, maize and porridge were recorded with mean fungal load of 2×10(8) CFU/ml, 1×10(7)CFU/g and 2×10(7)CFU/g respectively. Additionally, A. flavus, A. parasiticus, F. verticillioides, F. proliferatum, P. verrucosum, P. aurantiogriseum and M. suaveolens were the most frequent fungal isolates in houseflies with incidence rate of 34%, 11%, 27%, 21%, 22%, 17% and 32% respectively. F. verticillioides, A. flavus, A. niger and P. oslonii were the most prevalent species contaminating porridge and maize with incidence rate of 23%, 32%, 16% and 28% in maize samples, while incidence rates of 59%, 15% and 29% were recorded in porridge samples with the exception of F. verticillioides. The prevalence of these genera of fungi may pose serious health risks.

  18. From health services to medical markets: the commodity transformation of medical production and the nonprofit sector.

    Science.gov (United States)

    Imershein, A W; Estes, C L

    1996-01-01

    In recent years the language and logic of medical care have moved from providing medical services to marketing product lines. Analysis in this article examines this task transformation and its implications for transformation of the nonprofit sector and of the state. The authors argue that these transformations are essential explanatory elements to account for the origins of medical services in the nonprofit sector, the early exclusion of capitalist organizations from hospital care, and the changes that fostered corporate entry. To wit, medical care tasks have undergone a two-stage transformation. The first transformation changed open-ended, ill-defined services with uncertain funding into more highly organized and codified services with stable funding, attracting both capitalist enterprises and capitalist logic into the nonprofit sector. The second transformation standardized medical care tasks into product lines, a process that also challenged the status of the nonprofit organizations performing these tasks. In an analysis of the second transformation, the authors argue that this challenge is in the process of turning back upon itself, undermining the conditions that fostered capitalist entry into medical care delivery in the first place.

  20. Evaluating opportunities to improve material and energy impacts in commodity supply chains

    Energy Technology Data Exchange (ETDEWEB)

    Hanes, Rebecca J.; Carpenter, Alberta

    2017-01-10

    When evaluated at the scale of individual processes, next-generation technologies may be more energy and emissions intensive than current technology. However, many advanced technologies have the potential to reduce material and energy consumption in upstream or downstream processing stages. In order to fully understand the benefits and consequences of technology deployment, next-generation technologies should be evaluated in context, as part of a supply chain. This work presents the Materials Flow through Industry (MFI) supply chain modeling tool. The MFI tool is a cradle-to-gate linear network model of the US industrial sector that can model a wide range of manufacturing scenarios, including changes in production technology and increases in industrial energy efficiency. The MFI tool was developed to perform supply chain scale analyses in order to quantify the impacts and benefits of next-generation technologies and materials at that scale. For the analysis presented in this paper, the MFI tool is utilized to explore a case study comparing three lightweight vehicle supply chains to the supply chain of a conventional, standard weight vehicle. Several of the lightweight vehicle supply chains are evaluated under manufacturing scenarios that include next-generation production technologies and next-generation materials. Results indicate that producing lightweight vehicles is more energy and emission intensive than producing the non-lightweight vehicle, but the fuel saved during vehicle use offsets this increase. In this case study, greater reductions in supply chain energy and emissions were achieved through the application of the next-generation technologies than from application of energy efficiency increases.

    As a bond of communication between commodities and customers, commodity packaging has a commutative relationship with the mentality of customers. On one hand, commodity packaging influences the customers through appearence like color, shape, words, pictures and symbols, which attract their attention, initiate their emotion, inspire their desire, and then, lead to the acquisition. On the other hand, the characteristics and rules of the mentality and behavior of the customers are the gist and precondition of commodity packaging, i.e., commodity packaging shuold conform to the characteristics of individual customer or customers' mental demands as a group.%商品包装作为商品与消费者之间的信息纽带,与消费者心理之间存在着相互影响的互动关系。一方面,商品包装通过色彩、造型、文字、图案、标志等外观形象作用于消费者的感官,促使其产生注意,引发情感,形成动机,导致购买;另一方面,消费者的心理和行为特点及规律又是进行包装设计的依据和前提条件,即商品的包装设计必须符合消费者个体和群体的心理需求特点。

  14. Estimation of Truck Trips on Large-Scale Irrigation Project: A Combinatory Input-Output Commodity-Based Approach

    Full Text Available For the agricultural-based countries, the requirement on transportation infrastructure should not only be limited to accommodate general traffic but also the transportation of crop and agricultural products during the harvest seasons. Most of the past researches focus on the development of truck trip estimation techniques for urban, statewide, or nationwide freight movement but neglect the importance of rural freight movement which contributes to pavement deterioration on rural roads especially during harvest seasons. Recently, the Thai Government initiated a plan to construct a network of reservoirs within the northeastern region, aiming at improving existing irrigation system particularly in the areas where a more effective irrigation system is needed. It is expected to bring in new opportunities on expanding the cultivation areas, increasing the economy of scale and enlarging the extent market of area. As a consequence, its effects on truck trip generation needed to be investigated to assure the service quality of related transportation infrastructure. This paper proposes a combinatory input-output commodity-based approach to estimate truck trips on rural highway infrastructure network. The large-scale irrigation project for the northeastern of Thailand is demonstrated as a case study.

    Full Text Available In this study, we proposed a mathematical model for four-level defective goods supply chain with imperfect quality of commodity components in an uncertain state to maximize profit of supply chain. It is assumed that the inspection of incoming parts in suppliers is randomly done and incomplete. This lead some of the manufactured products will not be properly manufactured because of defective parts and are considered as defective goods and in most cases, the defective products can be repaired by replacing with the good parts. The defective parts will be collected and then returned to the suppliers for repairing. Out proposed model considers defective parts problem by optimizing the costs of production, maintenance, shipping, reworking on the defective goods and parts, shortage in retailers due to the production of defective goods and cost of capital incurred by the companies. The model can anticipate the active suppliers/manufacturers/distributors and the quantity of parts and goods that must be exchanged between them. Our proposed model is novel and we used MINOS solver and LINGO software to solve the problem. The results ascertained the correctness and fine function of the proposed model.

  16. Carboxylic acid reductase is a versatile enzyme for the conversion of fatty acids into fuels and chemical commodities.

    Aliphatic hydrocarbons such as fatty alcohols and petroleum-derived alkanes have numerous applications in the chemical industry. In recent years, the renewable synthesis of aliphatic hydrocarbons has been made possible by engineering microbes to overaccumulate fatty acids. However, to generate end products with the desired physicochemical properties (e.g., fatty aldehydes, alkanes, and alcohols), further conversion of the fatty acid is necessary. A carboxylic acid reductase (CAR) from Mycobacterium marinum was found to convert a wide range of aliphatic fatty acids (C(6)-C(18)) into corresponding aldehydes. Together with the broad-substrate specificity of an aldehyde reductase or an aldehyde decarbonylase, the catalytic conversion of fatty acids to fatty alcohols (C(8)-C(16)) or fatty alkanes (C(7)-C(15)) was reconstituted in vitro. This concept was applied in vivo, in combination with a chain-length-specific thioesterase, to engineer Escherichia coli BL21(DE3) strains that were capable of synthesizing fatty alcohols and alkanes. A fatty alcohol titer exceeding 350 mg·L(-1) was obtained in minimal media supplemented with glucose. Moreover, by combining the CAR-dependent pathway with an exogenous fatty acid-generating lipase, natural oils (coconut oil, palm oil, and algal oil bodies) were enzymatically converted into fatty alcohols across a broad chain-length range (C(8)-C(18)). Together with complementing enzymes, the broad substrate specificity and kinetic characteristics of CAR opens the road for direct and tailored enzyme-catalyzed conversion of lipids into user-ready chemical commodities.

    TiO2 nanotubes demonstrated to be a versatile nanostructure for biomaterials, clean energy and water remediation applications. However, the cost of titanium and the poor mechanical properties of the nanotubes hinder their adoption at large scale. This work presents a straightforward and scalable method for transferring photoactive anodic TiO2 nanotubes from titanium foils to commodity thermoplastic polymers, polypropylene, polyethylene terephthalate, polycarbonate, and polymethylmetacrylate, allowing the reusing of the remaining titanium. The obtained flexible nanocomposites reach a maximum photonic efficiencies of 0.038% (ISO-10678:2010) representing the 93% of photonic efficiency of TiO2 nanotubes on titanium. In addition, the nanocomposites and TiO2 nanotubes on titanium present similar antibacterial properties under 1 mW cm-2 UV-A, 60% of Escherichia coli survival after 1 h of exposition. The final objective of this work is to point out main concepts and key parameters for a low-cost fabrication of a photoactive nanocomposite material.

  18. Biocatalyzed processes for production of commodity chemicals: Assessment of future research advances for N-butanol production

    This report is a summary of assessments by Chem Systems Inc. and a further evaluation of the impacts of research advances on energy efficiency and the potential for future industrial production of acetone-butanol-ethanol (ABE) solvents and other products by biocatalyzed processes. Brief discussions of each of the assessments made by CSI, followed by estimates of minimum projected energy consumption and costs for production of solvents by ABE biocatalyzed processes are included. These assessments and further advances discussed in this report show that substantial decreases in energy consumption and costs are possible on the basis of specific research advances; therefore, it appears that a biocatalyzed process for ABE can be developed that will be competitive with conventional petrochemical processes for production of n-butanol and acetone. (In this work, the ABE process was selected and utilized only as an example for methodology development; other possible bioprocesses for production of commodity chemicals are not intended to be excluded.) It has been estimated that process energy consumption can be decreased by 50%, with a corresponding cost reduction of 15-30% (in comparison with a conventional petrochemical process) by increasing microorganism tolerance to n-butanol and efficient recovery of product solvents from the vapor phase.

    The occurrence of falls inside the home is a common yet potentially hazardous issue for adults as they age. Even with the installation of physical aids such as grab bars, weight transfers on and off a toilet or bathtub can become increasingly difficult as a person's level of physical mobility and sense of balance deteriorate. Detecting this deterioration becomes an important goal in fall prevention within a smart home. This paper develops an unobtrusive method of analyzing the usage of toilet grab bars using pressure sensors embedded into the arm rests of a commode. Clinical parameters are successfully extracted automatically from a series of stand-to-sit (StSi) and sit-to-stand (SiSt) transfers performed by a trial group of young and older adults. A preliminary comparison of the parameters indicates differences between the two groups, and aligns well with published characteristics obtained using accelerometers worn on the body. The unobtrusive nature of this method provides a useful tool to be incorporated into a system of continuous monitoring of older adults within the smart home environment.
