Full textAbstract:
With the aid of Hannah Arendt’s distinction between authentic and inauthentic semblances, this article reconstructs Karl Marx’s notion of commodity fetishism as a phenomenological concept. It reveals two distinct interpretive moments in the fetish: the interpretation of goods as anonymous in exchange and the interpretation of commodity-exchange as natural. As authentic semblances, interpretations in commodity-exchange cannot be “seen through” or corrected with a shift in perspective; in contrast, as inauthentic semblances, interpretations of commodity-exchange can be corrected with such a shift. This reconsideration of commodity fetishism suggests phenomenology and interpretive analysis should contribute to an analysis of region and globe-defining social systems.

This article builds on Whitley's comparison of the business systems and global commodity chains approaches to the study of economic organization within and across nations and regions. My objective is to provide a fuller exposition of the logic and evidence underlying the emergence, evolution, and variation in buyer-driven and producer-driven commodity chains. While there are clearly national differences within commodity chains, the idea that nations matter more than industrial sectors in generating contrasting forms of economic organization in global capitalism remains debatable. One of the central propositions of the commodity chains perspective is that globalization tends to diminish the influence of national origins on business systems. The way firms do business in the international economy thus is determined to an increasing extent by their position in global commodity chains, not their national origins. Nonetheless, because they highlight different units and levels of analysis, the business systems and commodity chains approaches are best viewed as complementary (rather than competing) theoretical frameworks.

It has been observed that there has been a great interest in computing experiments which has been useful on shared nothing computers and commodity machines. We need multiple systems running in parallel working closely together towards the same goal. Frequently it has been experienced and observed that the distributed execution engine named MapReduce handles the primary input-output workload for such clusters. There are numerous distributed file systems around viz. NTFS,ReFS,FAT,FAT32 in windows and linux, we studied them and implemented a few distributed file systems. It has been studied that distributed file systems (DFS) work very well on many small files but some do not generate expected output on large files. We implemented benchmark testing algorithms in each distributed files systems for small and large files, and the analysis is been put forward in this paper. Even we came across the various implementation issues of various DFS, they have also been mentioned in this paper.

Full textAbstract:
The article presents studies of the logistics structure of commodity market, based on the provisions of the general parametric theory of systems (GPTS). The logistics analysis of commodity movement on the market is presented and typical scheme of goods movement on a logistic chain is offered. Considering market logistics as an organizational system, the article presents its parametric model in the form of a matrix, the elements of which are logistic entities with their connections. It is proved, that the main basic element of the matrix structure of logistics system of commodity movement is a business entity that participates in the production and promotion of goods on the market. The types of business entities, which operating in the logistics system of the commodity market, are systematized. It is determined that business entities, which are distributed in logistics chains and their links, perform certain logistics functions due to their properties. It has been proved that business entities, which can be included as elements of the matrix market structure, should have the functions of performing logistics services. The content of these services is revealed and analyzed. The use of the corresponding target function in calculating the optimal logistics chains of commodity movement in the market is substantiated. The application of this approach, based on the multi-attribute utility theory (MAUT) is shown. It is determined that the goal of the proposed target function, by which the value added chain is calculated, is its maximization in the supply chain. Calculations for the target function allow you to determine the optimal route of commodity movement in the market and the relevant logistics entities through which this route passes. Thus, it is proposed to organize (highlight) the most profitable logistics chains of the market, which will significantly reduce the logistics costs of commodity movement, as well as reduce the risks of logistics barriers.

Topicality. The instability of the external environment is becoming a permanent condition for the functioning of commodity market systems, to which it is necessary to quickly adapt. Ensuring the reproduction development of systems of vertically adjacent commodity markets requires the acquisition of a certain stability (resilience) by the market system, which makes it necessary to study the essence of this category in the market dimension. In the war and post-war period, studies of the stability of commodity markets in the context of national security become especially relevant.Aim and tasks. The purpose of the article is to substantiate the theoretical foundations of the resilience of commodity market systems based on a reproducible approach in conditions of instability. The following methods were used during the research: dialectical, theoretical generalization and comparison, structural-logical method.Research results. Based on the content analysis of the "economic stability" category, it was established that in peacetime the essence of stability was determined by the preservation and improvement of the parameters of the economic system, while in the wartime the key component is their restoration, that is, resilience. The connection and mutual influence of the stability of functioning on the stability of the development of systems of adjacent markets is substantiated, the author's definition of the category "stability of reproduction development" is given. The essence of the basic principles of regulating the resilience of commodity market systems is defined: preventiveness, alternativeness and priority of the economic interests of the state. The relationship and mutual influence of the resilience of commodity markets, as a component of the national resilience system, on national security is substantiated.Conclusion. The scientific novelty of the conducted research consists in the development of the theoretical foundations of the resilience of commodity market systems based on a reproduction approach by transforming the theoretical provisions of economic stability in the market dimension, taking into account the conditions of the wartime period. The theoretical foundations of market resilience developed in the article form a scientific basis for the justification of adaptive mechanisms for regulating the stability of functioning and development of commodity market systems, which can be implemented by state authorities at different levels of management.

Full textAbstract:
The article is aimed at defining the feasibility of using the Sitniks CRM software for small commodity businesses, examining its compliance with the standard and the main competitive advantages among such products. Analyzing and generaling the scientific works of many scholars, the positive impact of high-quality information provision on the activities of the enterprise is proved. However, despite the obvious benefit of using automation systems, a bigger share of Ukrainian entrepreneurs do not use CRM systems (Customer Relationship Management systems) either due to lack of awareness or unsuccessful implementation experience. The article uses comparative and matrix analyses. A comparative analysis of competitors shows that the researched CRM system stands out among others with a high level of flexibility and personalization, which is the main advantage of this software. During the SWOT analysis, the factors influencing the development of the company were worked out in detail. It is found that the main drawback of this software is a relatively long implementation period, and its capabilities and threats are, accordingly, scaling and increasing competitors in a niche. It is concluded that the Sitniks CRM system is not just a system for simplifying and automating business processes, but a platform that has sufficiently powerful functionality due to customization, integration, tracking capabilities and ease of use. The implementation of this software will lead the company to increase productivity, allowing to effectively plan and control, as well as establish strong relationships with customers.

The determination of value of information or information systems is a basic issue for information management. In order to solve it several questions must be answered like: what is the object of valuation; how is value defined and measured; and what constitutes a coherent and usable method for valuation. In this paper an approach is outlined that combines the information commodity approach, activity-based costing, and graph modelling. The first is used to define the object of analysis (an information commodity) and the nature of value (the demand value at the marketplace). The third allows the modelling of business processes in terms of activities and cost relations between activities. The second enables the assignment of costs to activities modelled in the graph. Together they constitute a coherent and usable method for determining the value of IS. This is illustrated by means of a case study.

The paper presents the features of terminology and classification of fish products for food and non-food purposes in the nomenclature of various levels: national (All-Russian product classifier by economic activity (RCPA 2) and international (The Foreign Economic Activity Commodity Nomenclature of the Customs Union (FEACN of the CU). In the course of the study there was conducted a comparison of the codes of fish products within the framework of the existing methodology for the formation of transition keys. In the classification of fish products in FEACN of CU there has been stated the imperfection of methodological and information base, illogicality and ambiguity associated with the lack of clear definitions of terms in EAEU Commodity Nomenclature for Foreign Economic Activity and in regulatory documents, with a discrepancy between concepts adopted in commodity research and international commodity nomenclature, as well as the lack of development of fish product identification for customs regulation in terms of specificity of the consumer properties of fish products. Correspondence of the codes of the international commodity nomenclature (UCN FEA EAEU) and the Russian classifier (RCPA 2) is recorded in the table reflecting the possible correlation options for the codes of the classifiers in relation to certain types of fish products (fish meal, fish glue, fish gelatin, fish roe), which are set by transition keys. There has been required the development of a unified approach to the interpretation of fish product codes under the FEACN of CU, as well as the development of unified terminology for omitting
a subjective assessment in the analysis of consumer properties and product indicators.

To analyze different methodological approaches to determining the marketing attractiveness of international markets and their convergence assessing. Develop an indicators system for assessing the convergence of international markets to determine their marketing attractiveness for domestic agricultural enterprises. The international markets have been rated on the basis of summing the ranks of indicators of attractiveness method of their business environment for Ukrainian farmers by the product group «1008 Buckwheat, millet and other cereals» in order to identify more favorable conditions for doing business. The application of this approach allowed to develop a target portfolio for further targeting the implementation of the internationalization strategy by domestic producers of the product group «1008 Buckwheat, millet and other cereals». The methodological basis of the study are general and special research methods: epistemological and systems analysis - in the study of «economic convergence» definition; systems theory and systems analysis - to analyze of process determining the marketing attractiveness of international markets and assessing their convergence; statistical analysis, synthesis and comparison ‒ to identify trends in the entry of agricultural enterprises of Ukraine to international markets; comprehensive assessment of the convergence of agricultural enterprises of Ukraine under the conditions of international diversification. It has been proved that in the expert assessment of convergence indicators the markets of foreign countries, the indicators of which are as close as possible to the economy of Ukraine, should be singled out. It has been determined that the markets of Austria and Nigeria are promising for domestic agricultural enterprises, producers of the commodity group «1008 Buckwheat, millet and other cereals», with the possibility of overcoming a significant gap in certain indicators, namely: the market of Austria, Nigeria where there is low quality regulation and also unfavorable investment conditions. The scientific and methodological approach to the complex assessment of the convergence of new international markets for domestic agricultural enterprises under the conditions of international diversification has been substantiated and developed. The result of the evaluation allowed to come up to the conclusions about the marketing opportunities of domestic agricultural enterprises under the conditions of entering the markets of these countries. As a result of the proposed approach, it is possible to identify foreign markets that demonstrate favorable conditions for doing business in them, which indicates the presence of convergent conditions, which is a prerequisite for the entry of goods of domestic agricultural enterprises in the markets of these countries. As a result of the proposed approaches, there were identified new international markets, that demonstrated favorable conditions for doing business in them by domestic agricultural enterprises producing the product group «1008 Buckwheat, millet and other cereals». It has beed developed in the study a target portfolio for further targeting the strategy implementation of internationalization domestic producers of the product group «1008 Buckwheat, millet and other cereals».

Full textAbstract:
Distributed forecasting of agriculture commodity prices has an attractive research perspective that delivers active breakthrough analysis of the rapid fluctuations in pricing forecasts for participating stakeholders without being manually dispatched lists. The increased use of an efficient forecasting mechanism for the agriculture information management of generated records and processing creates emerging challenges and limitations. These include new government mandates and regulations, the price of land for expansion, forecasting the growing demand for commodities, fluctuations in the global financial market, food security, and bio-based fuels. Building and deploying distributed dynamic scheduling, management, and monitoring systems of agricultural activities for commodity price forecasting and supply chains require a significant secure and efficient approach. Thus, this paper discusses a collaborative approach where two different folds are demonstrated to cover distinct aspects with different objectives. A metaheuristic-enabled genetic algorithm is designed to receive day-to-day agricultural production details and process and analyze forecast pricing from the records by scheduling, managing, and monitoring them in real-time. The blockchain hyperledger sawtooth distributed modular technology provides a secure communication channel between stakeholders, a private network, protects the forecasting ledger, adds and updates commodity prices, and preserves agricultural information and node transactions in the immutable ledger (IPFS). To accomplish this, we design, develop, and deploy two distinct smart contracts to register the system’s actual stakeholders and allow for the addition of node transactions and exchanges. The second smart contract updates the forecasting commodity pricing ledger and distributes it to participating stakeholders while preserving detailed addresses in storage. The simulation results of the proposed collaborative approach deliver an efficient E-agriculture commodity price forecast with an accuracy of 95.3%. It also maintains ledger transparency, integrity, provenance, availability, and secure operational control and access of agricultural activities.

Food resilience is a condition of the fulfillment of food in sufficient quantities, safe for consumption, distributed evenly, and affordable. Carrying capacity is an important factor in fulfilling these aspects. The carrying capacity in this study is assessed from the suitability of land and community acceptance of the commodities developed in Kampung Wapeko. Rice is a commodity that is currently a concern of the Government to be developed in Wapeko. Meanwhile sago is a local food commodity that has been consumed and processed by indigenous people of Wapeko for generations. Based on land suitability analysis, this study shows that rice commodity has a level of land suitability marginal (S3) until not appropriate (N). Meanwhile, sago commodity has appropriate land suitability level (S1) until marginal fit (S2). Analysis of community acceptance of rice and sago commodities shows that rice has become the staple food of the community in Kampung Wapeko, while sago only as a food interlude. The results indicate that rice is more accessible because of the subsidy scheme, while sago is harder to reach, due to the reduced sago tree population and can only be taken at certain times. The sustainable food security strategy designedin this research is developing commodities in accordance with land use directives and creating self-reliance of local communities through the development of commodity cultivation in accordance with their knowledge systems

With the development of the social economy and the improvement of the consumption concept, a new business model combining offline and online has been promoted. The warehousing system is one of the important links of commodity production and circulation, which involves storage, sorting, and distribution. It has a significant impact on the operation cost and the efficiency of the whole logistics system. The progress of robot technology, the Internet of things, and artificial intelligence technology promotes the automation and intelligence of storage systems. The Robotic Mobile Fulfillment Systems (RMFS), which takes the automatic guided vehicles (AGVs) as the way of handling and picking, greatly improves the space utilization, operation efficiency, and flexibility of the system. This paper studies the RMFS with fixed shelves and establishes the performance evaluation model of the picking system considering the AGVs congestion by establishing the queuing network. The effectiveness of the model is verified by simulation, and the optimization of system parameter configuration is further discussed according to the experimental data.

ObjectivesMost non-communicable diseases are preventable and largely driven by the consumption of harmful products, such as tobacco, alcohol, gambling and ultra-processed food and drink products, collectively termed unhealthy commodities. This paper explores the links between unhealthy commodity industries (UCIs), analyses the extent of alignment across their corporate political strategies, and proposes a cohesive systems approach to research across UCIs.MethodsWe held an expert consultation on analysing the involvement of UCIs in public health policy, conducted an analysis of business links across UCIs, and employed taxonomies of corporate political activity to collate, compare and illustrate strategies employed by the alcohol, ultra-processed food and drink products, tobacco and gambling industries.ResultsThere are clear commonalities across UCIs’ strategies in shaping evidence, employing narratives and framing techniques, constituency building and policy substitution. There is also consistent evidence of business links between UCIs, as well as complex relationships with government agencies, often allowing UCIs to engage in policy-making forums. This knowledge indicates that the role of all UCIs in public health policy would benefit from a common approach to analysis. This enables the development of a theoretical framework for understanding how UCIs influence the policy process. It highlights the need for a deeper and broader understanding of conflicts of interests and how to avoid them; and a broader conception of what constitutes strong evidence generated by a wider range of research types.ConclusionUCIs employ shared strategies to shape public health policy, protecting business interests, and thereby contributing to the perpetuation of non-communicable diseases. A cohesive systems approach to research across UCIs is required to deepen shared understanding of this complex and interconnected area and also to inform a more effective and coherent response.

Red chili is Indonesia's leading commodity. Red chili is a raw material for various food products, cosmetics, pharmaceuticals and others. Fluctuations in the availability of red chili commodity supply affect the price of red chili commodity products. Pricing can occur because of supply and demand. Uncertain conditions also influence pricing due to fluctuations in raw material prices, ultimately affecting the price of carrageenan products. This condition makes price determination very difficult. Therefore, this study aims to analyze and design a pricing mechanism and determine the optimal margin in the red chili commodity marketing system. This study uses a systems analysis and design approach. Input-process-output (IPO) diagrams describe system requirements. Industrial business processes are described by the Business Process Model and Notation (BPMN) ver. 16.0. Meanwhile, to determine the optimal margin, Sugeno's fuzzy inference system approach is used by simulating the model in 3 margin scenarios: pessimistic, moderate, and optimistic. The simulation results were tested using the MAPE test, in which the results were compared between fuzzy price results and markup prices using markup values of 20%, 25%, and 30%. The analysis results show that the price is determined by demand and supply. The price obtained from the formulation of the Sugeno fuzzy model shows an optimal margin of Rp. 16,600.

Weekly live cattle prices in various markets would be expected to share common trends, i.e., they cannot be driven by separate nonstationarities because at some point the prices will diverge sufficiently for it to be economic to cross-ship the cattle, or at least the beef. This paper extends previous bivariate work to a multivariate analysis that is capable of modeling the multiple market linkages in prices for many geographical regions. The empirical estimation represents the application of an innovation on Aoki's Linear Systems State Space model that allows determination of long- and short-run dynamics common to multiple series. The common dynamics permit characterization of the multiple markets with a limited number of states (sufficient statistics for the past), resulting in dynamic arbitrage relations between the series. A nonparametric test is used to evaluate the value of expected arbitrage forecasts implied by the structure of the model. The arbitrage relationship also is employed to generate efficient discounts/premiums for either physical delivery or cash settlement of futures contracts. The proposed settlement mechanism accounts for spatial arbitrage opportunities and therefore better represents the true geographical discounts faced by traders in individual markets.

This study aims to investigate the dynamic correlations (co-movement) in between energy commodities such as WTI Crude Oil (WOIL), Brent Crude Oil (BOIL), Heating Oil and Electricity prices. To achieve this goal, we employed partial wavelet coherence (PWC) and multiple wavelet coherence (MWC). Wavelet analysis constitutes the core of these methodologies and MWC is essential to determine the dynamic correlation (co-movement) of time intervals and scales between the time series. We have developed a software program to compute PWC and MWC for quadruple data set. Coherent time intervals of the time series are determined. Vector ARMA models are shown to give a good fit due to having low mean squared errors compared to the univariate case. This allowed us to have better forecast performance.

HighlightsMeeting the 0.9% tolerance level was challenging under most conditions.Non-GM loads in the simulation were able to meet a 1.5% or 3% tolerance level under specific conditions.Field isolation distance plays a large role in a non-GM load meeting the posted tolerance levelAbstract. The open-air growth environment used in maize production makes it nearly impossible to ensure 100% purity of specified genetic traits. One measure of successful coexistence is a low level of unintended material in seed, grain, and feed or food products, termed “adventitious presence” (AP). To allow the coexistence of genetically modified (GM) and non-genetically modified (non-GM) maize, tolerance levels regulate how much AP of genetically modified corn is allowed in each unit of maize. This research sought to model four factors contributing to levels of adventitious presence: seed purity, field isolation distance, combine cleanout, and grain elevator receipt and handling practices. Monte Carlo simulation was used to test nine scenarios to determine the feasibility of successfully meeting three tolerance levels for adventitious presence (0.9%, 1.5%, and 3.0%). After 50,000 iterations for each model, sensitivity analysis was performed to identify factors that play an important role in whether the load meets the posted tolerance level or not. Results suggest that non-GM maize loads would not meet a tolerance level of 0.9% in most cases. Non-GM maize loads were found to meet tolerance levels of 1.5% and 3.0% in certain cases. The most significant factors affecting the probability of the unit of maize meeting the posted tolerance level were field isolation distance, elevator handling practices, and seed purity.

The research is devoted to the scientific analysis of the rational choice principles of commodity specialization taking into account the functioning specifics of agricultural enterprises. The main tasks are identified, the solution of which has the potential to improve the internal specialization. There are among them: the maximum production increase in each unit, effi-cient use of production funds and work-force, improving the production efficiency. The adaptation process of commodity specialization of agricultural enterprises to market conditions is structured. Eight stages of it are distinguished: from deter-mining the change volume related to the enterprise adaptation to the external environment, to adjusting the system of opera-tional, tactical and strategic planning. In the factor analysis framework of the internal and external environment of agrarian enterprise, the determinants of its product specialization are systematized. The author's vision of the organizational and economic mechanism of managing the specialization of agricultural enterprises is outlined. The tendency to update the re-search of the risk system in the managing process the specialization of agricultural enterprises has been noted. This system has included the following risks: market, personnel, financial, legal, natural-climatic, logistical, agro-technological, the only mechanism for regulation in many branches of agriculture. The conclusion is made that substantiation of construction con-ceptual bases of organizational and economic mechanism of commodity specialization management of agrarian enterprise allows to realize adaptation development strategies of production and commercial activity. The basis is a comprehensive consideration of the factors of external and internal environment in the components mobilization of production and economic potential, as well as determining the configuration of management systems of commodity specialization in enterprise man-agement.

SUMMARYA late-maturing, high-yielding maize released for the Burundi highlands was rejected by subsistence farmers. Analysis of this variety in terms of the local cropping system shows that it offers no advantage over earlier maturing varieties when whole-system biological and economic yield and Land Equivalent Ratios are examined, while farmer risk is apparently substantially increased. The value of incorporating a ‘farming systems’ approach into national commodity research programmes in developing countries is demonstrated.

The study is based on the method of factor analysis,which allows us to speed up the assessment of producersof Kalmyk and Hereford cattle breeds by the quality of theiroffspring. The studies were conducted on a large sample ofdata, including various evaluation parameters of 96 breedingbulls and 272 sons. Indicators have been developed forone feature, which is quite suitable for the preliminary selectionof steers in breeding and commodity farms engagedin the breeding of beef cattle. For the final assessment, wehave compiled new indicators as follows: two indicators - liveweight at 8 and 15 months, live weight at 15 months and averagedaily increase from 8 to 15 months; three characteristics- live weight at 8, 15 months and average daily increase. Theseindicators are objective and easily measurable over a relativelyshort period of time. According to the estimates obtainedfor individual sons, it is possible to determine the evaluationof breeding bulls by the quality of offspring by summing thevalues of the new factors.

Abstract Plastic waste is one of the most pressing global environmental challenges. As the world’s largest plastic waste generator and importer, China has implemented various policies to promote sustainable plastic waste management. However, the quantitative understanding of China’s application-specific plastic waste recycling and its infrastructure development is still quite limited. Here, we build up a unified framework to investigate the recycling and the corresponding infrastructure status of five commodity plastics in China, which are polyethylene, polypropylene, polyvinyl chloride, polystyrene and acrylonitrile-butadiene-styrene (PE, PP, PVC, PS, ABS) from 2000–2019. We find that: (1) in total, China consumed around 981.4 million tons (Mt) of the five commodity plastics from 2000–2019, generating 590.4 Mt of plastic waste, only 27% of which was recycled, 34% was landfilled and 32% was incinerated; (2) PP (∼30%) and PE (∼28%) have the highest recycling rate in China, which is related to their huge consumption base, while PS and ABS have the lowest recycling rate at only ∼26%; (3) the waste recycling performance is determined by its applications, and the worst recycling rates (<20%) are the packaging and commodity sectors due to their poor collection, while higher recycling rates (⩾30%) are found in the building and construction, agriculture and transportation sectors due to the special waste collection systems in these sectors; (4) our further examination of the recycling potential reveals that around 56% of packaging waste can be recycled by adjusting waste management infrastructure (in the collection, pre- and end-processing). Our results can help bridge information gaps and support policymaking to improve sustainable plastic waste management.

Classic vector systems have all but vanished from recent TOP500 lists. Looking at the recently introduced NEC SX-9 series, we benchmark its memory subsystem using the low level vector triad and employ the kernel of an advanced lattice Boltzmann flow solver to demonstrate that classic vectors still combine excellent performance with a well-established optimization approach. To investigate the multi-node performance, the flow field in a real porous medium is simulated using the hybrid MPI/OpenMP parallel ILBDC lattice Boltzmann application code. Results for a commodity Intel Nehalem-based cluster are provided for comparison. Clusters can keep up with the vector systems, however, require massive parallelism and thus much more effort to provide a good domain decomposition.

Abstract The highlands in Central Java have a major contribution to meet the national demand for vegetables. However, competition for these lands by non-agricultural sectors or for the production of other agricultural commodities could lead to a decline in vegetable production. The research aimed to spatially analyze the land suitability and availability for highland vegetable commodities. It also aimed to analyze the land potential for the development of vegetable commodity areas. The research was carried out in Banjarnegara and Wonosobo Regencies, at an altitude of more than 700 meters above sea level, from July to December 2020. The methodology used was Multi-Criteria Decision Making with Analytical Hierarchy Process structure and map overlay, using ArcGIS ver. 10.5. The results showed that land which is suitable for the highland vegetable commodities was at 33.52%, it was dominated by a class of moderately suitable (S2). Furthermore, the suitable and available land for vegetable cultivation covers an area of 16.03 %. Finally, there were 9,911.2 hectares of land that had not been optimally used and had the potential to become a development area for highland vegetable commodities in the future.

Abstract The global food system is increasingly interconnected and under pressure to support growing demand. At the same time, crop production is facing new and uncertain impacts from climate change. To date, understanding how downstream supply chain actors, such as commodity traders, are exposed to climate change risks has been difficult due to a lack of high-resolution climate and trade data. However, the recent availability of supply chain data linking subnational production to downstream actors, and gridded projections of crop yield under climate change, allows us to assess individual commodity trader exposure to long-term climate change risk. We apply such an analysis to soy production in Brazil, the world’s largest soy exporter. Whilst uncertainty across crop models’ yield projections means it remains difficult to accurately predict how production across the region will be affected by climate change, we demonstrate that the risk exposure of trading actors differs substantially due to the heterogeneity in their sourcing. Our study offers a first attempt to analyze subnational climate risk to individual trading actors operating across an entire production landscape, leading to more precise risk exposure analysis. With sufficient subnational data, this method can be applied to any crop and country combination, and in the context of wider food security issues, it will be pertinent to apply these methods across other production systems and downstream actors in the food system.

Cloud computing is one of the frontier technologies, which over the last decade has gained a widespread commercial and educational user base. OpenStack is one of the popular open source cloud management platforms for establishing a private or public Infrastructure-as-a-Service (IAAS) cloud. Although OpenStack started with very few core modules, it now houses nearly 38 modules and is quite complex. Such a complex software bundle is bound to have an impact on the underlying hardware utilization of the host system. The objective is to monitor the usage of system resources by OpenStack on commodity hardware. This paper analyzes the effect of OpenStack on the host machine's hardware. An extensive empirical evaluation has been done on different types of hardware, at different virtualization levels and with different flavours of operating systems comparing the CPU utilization, memory consumption, disk I/O, network, and I/O requests. OpenStack was deployed using Devstack on a single node. The novel aspect of this work is monitoring the resource usage by OpenStack without creating virtual machines on commodity hardware. From the analysis of data, it is observed that standalone machine with Ubuntu server operating system is the least effected by OpenStack and thereby has more available resources for computation of user workloads.

A simulation model for order and supply management was developed and a simulation model for order and supply management was tested using the example of Master-Torg LLC. Dependences of the enterprise activity on various factors have been determined Comparison of the cybernetic and systemic approaches is carried out. In order to generalize the experience in this direction, the advantages and disadvantages of existing models, as well as the methodology for their compilation, are considered. The general characteristics of the company are considered. The analysis of the external environment and competitive advantages of the company was carried out, respectively, Pest was carried out – an analysis and analysis of Porter’s five forces. The results of the experiments made it possible to establish that the use of the conjugate gradient method has reduced the number of backorders by 5 times. The simulation model fairly accurately simulates the market mechanism for coordinating orders and deliveries over time. This development is recommended for use in the distribution company Master-Torg LLC. In addition, it can be applied to any commercial company, subject to the adjustment of the corresponding restrictions.

In this article, the author is analyzing, deriving from logistic considerations, according to which principles of such delivery system should be designed, what can be the criterion of its efficiency, how volumes of cargo transported through various channels influence self‐organizing capacity of the system as a whole, and what is the synergetic effect on the logistic system. The questions of designing logistic systems considered in this article on the example of potash fertilizers are, in many respects, common to all Byelorussian exporters.

Since the introduction of genetically modified (GM) crops, the commodity grain system has been under pressure to segregate GM and non-GM crops. Starting at the level of the grain handler, members of the grain supply chain have successfully used quality assurance and identity preservation programs to segregate non GM crops. Producers delivering high-value, identity-preserved crops have become interested in implementing these quality management systems at the farm level. We conduct a cost-benefit analysis that shows that quality assurance program may be profitable for producers, depending on their farm size and equipment management strategy.

Purpose – Through an empirical analysis of a consumption community, the purpose of this paper is to demonstrate that the theories of gift-giving, sharing and commodity exchange should not be kept separated but integrated into a unifying model. Design/methodology/approach – The paper provides new evidence about Bookcrossing.com, whose members share and give books as gifts; that is, physical goods rather than digital ones as in most of the communities considered in the literature. This community is analysed with qualitative tools, such as netnography, personal interviews and participant observation. Findings – The main result of the analysis of Bookcrossing is that gift-giving is not the only process responsible for value creation and distribution in consumption communities: sharing and commodity exchange also play a role. Furthermore, the paper provides new evidence about aspects of gift-giving and sharing that have received limited attention in the literature: collective reciprocity and anonymous sharing. Research limitations/implications – The limitations are related to the intrinsic properties of the methods employed (netnography, personal interviews and participant observation) and to the paper, which analyses only one community and one product category. The implications refer to the role of gift-giving in consumption communities and its relationships with other processes: consumer gift systems are not only gifting platforms, but they and the elements of sharing and commodity exchange need to be integrated. Practical implications – The empirical evidence and implications matter for the organisation and management of collaborative consumption platforms and the way in which traditional business models could and should interact with these platforms in an increasing number of businesses. Originality/value – The paper adds new evidence of and original insights into gift-giving and collective forms of exchange. Moreover, it provides managerial implications of the analysed community for the book publishing industry.

Full textAbstract:
There is more than a decade-long history of using static analysis to find bugs in systems such as Linux. Most of the existing static analyses developed for these systems are simple checkers that find bugs based on pattern matching. Despite the presence of many sophisticated interprocedural analyses, few of them have been employed to improve checkers for systems code due to their complex implementations and poor scalability. In this article, we revisit the scalability problem of interprocedural static analysis from a “Big Data” perspective. That is, we turn sophisticated code analysis into Big Data analytics and leverage novel data processing techniques to solve this traditional programming language problem. We propose Graspan , a disk-based parallel graph system that uses an edge-pair centric computation model to compute dynamic transitive closures on very large program graphs. We develop two backends for Graspan, namely, Graspan-C running on CPUs and Graspan-G on GPUs, and present their designs in the article. Graspan-C can analyze large-scale systems code on any commodity PC, while, if GPUs are available, Graspan-G can be readily used to achieve orders of magnitude speedup by harnessing a GPU’s massive parallelism. We have implemented fully context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases written in multiple languages such as Linux and Apache Hadoop demonstrates that their Graspan implementations are language-independent, scale to millions of lines of code, and are much simpler than their original implementations. Moreover, we show that these analyses can be used to uncover many real-world bugs in large-scale systems code.

Trend following strategy is a popular strategy that investors often use in trading around the world. Stocks are bought during an upswing and sold during a decline, the two main phases of the trend-following trading technique. This research evaluates the performance of the trend-following strategy in the Chinese commodity market by systematically employing quantitative methods to trade and get back test results for performance evaluation. The main trading indicator for this research is DMAC (Dual Moving Average Crossover) with a trend indicator called ADX for adjustment. As a kind of technical analysis, so-called “Dual Moving Average Crossovers” are often cited as providing reliable signs for discerning future stock price movements. By employing these indicators and systematically backtesting on 21 commodity futures for ten years, the research discovers that DMAC does not perform well (negative annualized return and sharpe ratio) from 2011 to 2021. By refining the strategy which is to replace DMAC with MACD (Moving Average Convergence/Divergence) and abandon ADX, the backtest result performs much better. The refinement suggests that the utilization of different trading signals/indicators will lead to a different performance of the trend following strategy in the Chinese commodity market. The research concludes that the trend following strategy is worthy of exploring in the Chinese commodity market in terms of using different trading indicators.

Reviewing and buying the right goods from online websites is growing day by day in today's fast internet environment. Numerous goods in the same label are available to consumers. It is thus a difficult job for consumers to pick up the correct commodity at a decent price under different market conditions. Therefore, it is important for owners of online shopping websites to better understand their customers' needs and offer better services. For these reasons, the access log documented a vast amount of data related to user interactions with the websites. This access log therefore plays a key role in predicting user access trends and in recommending the best product to consumers. This research work therefore focuses on one such methodology for evaluating the pattern and behavioral analysis of users in e-commerce websites.

To remedy this problem, it offers an analysis of social media systems as market monopolies that organize a self-defeating arms race among their customers. This arms race enables social networking sites (SNS) to extract large price surpluses, effectively exploiting their customers.

Abstract In Kenya, total fertility rate and contraceptive prevalence rate have shown marginal changes since the 1990s, raising questions about efficiency and effectiveness of provision of reproductive health services, which has received little attention in the country and elsewhere in Africa. We use data from Thika sub-county in central Kenya to conduct a cost-effectiveness analysis of family planning service provision alternatives. The results show that costs per couple year of protection vary widely across facilities within government and non-government providers, but are slightly higher amongst the former. The cost-effectiveness ratios were sensitive to exclusion of certain commodity costs. We conclude that family planning provision systems found in Thika are efficient but call for strengthening of lower level facilities, which are more cost effective and largely serve the poor.

Full textAbstract:
In 1993, the info-media companies, Philips and Sony brought their new digital audio recording systems (Digital Compact Cassette and the Mini Disc respectively) onto the market. Since both systems can make perfect digital copies of Compact Discs, this will dramatically affect the profitability of the pre-recorded music industry, which is a repeat of what occurred when audio cassettes were first introduced in the 1960s. The inability to enforce restrictions on copyright or patent infringement is considered a global problem by many firms in the so-called “sunrise industries”. This article situates the problem by presenting and analysing the commodity relations of the pre-recorded music industry within the framework of Marxist methodology. The methodology provides for unique insights into this problem for the capitalist mode of production and points to the possibilities for further research. A secondary, but methodologically important purpose of the article is to widen the potential for Marxist analysis itself by extending attention on the commodity relations-consumption component of the circuit of capital, an area given meager attention by Marxists in the past.
