Texte intégralRésumé :
Jute is one of Bangladesh 's main cash crops. The contribution of the jute sector to the economy of Bangladesh is enormous. In Bangladesh, Jute is a vital sector from economical, agricultural, industrial, and commercial perspectives. Different kinds of jute products are made in Bangladesh and the products are environmentally friendly as well. Every year Bangladesh earns an amount of foreign currency by exporting jute and jute products in different countries all over the world. That contributes to the national income of Bangladesh. Jute was once called Bangladesh's 'Golden Fibre. But this industry's present and future prosperity and growth are vulnerable. There exist many problems in the jute industry of Bangladesh, such as; lack of scientific knowledge and modern tools, market tools, unavailability of quality seeds, low productivity, inappropriate market forecasting, land fragmentation, natural calamities, conflicts and economic crisis in the world market, etc. Based on the existing problems, I will try to give some policies that may help to eradicate the problems and improve the present conditions of the jute industry in Bangladesh.

Texte intégralRésumé :
Historically, jute is known as the golden fibre of Bangladesh, a leading cash crop and major export item for Bangladesh. Unfortunately, the production and export of jute have been declining since the 1970s due to the various internal and external problems. The Bangladesh government has recently declared to shut down the production at all state-owned jute mills. This paper aims to determine the reasons behind the state-owned jute mills failure and feasible solutions to unravel the problems. An in-depth interview with 10 (ten) industry experts was conducted to collect primary data. Secondary information has been collected from different books, websites, articles and newspapers. The demand for various and versatile jute products has been increasing globally over the last two decades. Still, in Bangladesh, the jute sector's development is no longer satisfactory to retain its glorious position towards the world because of having some major problems such as mismanagement and corruption of BJMC, lack of modern machinery, lack of skilled workers, weak marketing and government policies etc. Most state-owned jute mills under BJMC are stuck in dishonesty and lavishness alongside ageing infrastructure. They have been incurring losses for years, turning profits in just four of the last 48 years. Reform and restructuring of BJMC, modernizing factory with the latest technology, providing enough training to employees, investment in research work, improvement in the production process, efficient marketing strategy and appropriate government policies might help the state-owned jute mills to regain its position in the national and international market. There are no reasons to shut down the production where reformation is adequate to make the state-owned jute mills profitable. At least, the time to shut down state-owned jute mills is not right due to the Coronavirus pandemic.

Texte intégralRésumé :
The application of adhesively bonded joints in automotive industry has increased significantly in recent years mainly because of the potential for lighter weight vehicles, fuel savings and reduced emissions. The use of composites in making automotive body components to achieve a reduced vehicle mass has also continuously increased. Natural fibre composites have recently attracted a great deal of attention by the automotive industry due to their many attractive benefits (e.g. high strength-to-weight ratio, sustainable characteristics and low cost). However, the literature on natural fibre-reinforced polymer composite adhesive joints is scarce and needs further investigation. The main objective of this study was to evaluate and compare the mechanical performance of adhesively bonded joints made of synthetic- and natural fibre-reinforced polymer composites. Similar and dissimilar single lap joints bonded with a modern tough structural adhesive used in the automotive industry, as well as the epoxy resin AR260 (the same resin used in composite fabrication) were tested. It was found that the average failure loads varied significantly with adhesive material strength and adherend stiffness. Furthermore, it was also observed that failure mode has a significant effect in failure load. The jute-based natural fibre composites joints, both hybrid and purely natural, were superior in strength compared to the sisal-based natural composites joints.

Texte intégralRésumé :
Water losses in irrigation canals occur during the process of water transportation, with seepage loss being the main contributor to total water loss in irrigation conveyance. Cracks and settlement are the most problematic factors affecting canal lining structures, leading to reduced performance of irrigation canals due to issues such as sediment deposition, waterlogging, and leakage. Seepage losses typically range from 20 % - 30 %, but this can be reduced to 15 % - 20 % with the use of canal lining. However, the concrete lining structure, being a thin plate, is prone to high rates of cracking, which weakens the performance of canals. Therefore, it is crucial to enhance the flexure and splitting-tensile strengths of concrete to control the rate of cracking in the canal lining. The splitting-tensile strength of concrete is particularly important in crack control. Hybridization of fibers, such as combining polypropylene and jute fibers, can efficiently enhance flexural toughness, flexural strength, and fracture energy more than using a single type of fiber. The overall aim of this review is to summarize the literature on the use of modern materials to reduce water losses in concrete canal lining. Initially, hybrid fibers (one natural fiber and one artificial fiber) are selected to explain the behavior of hybrid fiber reinforced concrete (HFRC). The crack arresting mechanism of HFRC can help reduce losses in concrete canal lining. The findings of this review will be valuable as a reference for both industry practitioners and academic researchers interested in the development of hybrid fiber reinforced concrete materials, particularly for canal lining applications.

Texte intégralRésumé :
At the moment, all economically developed countries face the problem of pollution of the surrounding world, and one of the main pollutants is packaging. Packaging helps to preserve its contents from various damages, and informative and attractive packaging is an indispensable attribute of the marketing process. Most products are Packed in a huge amount of film and paper, which is thrown out by the consumer to the landfill. As a result, there are growing landfills for garbage, 40 % of which is disposable packaging. In the conditions of increased demand for so-called healthy food products, the question of packaging this food in no less "healthy" packaging arose. Eco-friendly, biodegradable, and edible packaging is one of the relatively new trends in the field of ecology. The international standard ASTM D-6400 "Standard specification for marking plastics intended for aerobic composting in municipal or industrial facilities" regulates the development of bioplastic mass technologies. According to the Standard specification for compostable plastics, biodegradable and decomposable plastics are classified into the following groups: starch, cellulose and protein based plastics; aliphatic polyesters; polylactic acids; polytrihydroxybutyrate; polyhydroxalkanoates; bio-derived polyethylene and lipid-derived polymers. According to the method of decomposition, bioplastics are divided into compostable plastic and photo-degradable plastics. The range of biodegradable plastics includes: starch; natural polyesters; renewable resource polyesters; synthetic aliphatic polyesters; aliphatic-aromatic co-polyesters; hydro-biodegradable polyester; water-soluble polymers; photo-biodegradable plastics and controlled degradation of dietary supplements. In the Russian Federation, the issues of bioplastic production have not been developed and are not legally fixed. Today, the main types of edible packaging include natural casings for meat products, wafer cups for ice cream, craft paper, cardboard, wood, cellulose, and others. Jute bags are a potential biodegradable packaging material. Many companies produce modern disposable eco-friendly dishes made of wood, bamboo, carbonized bamboo, sugar cane and other eco-friendly materials without the use of chemicals.

Texte intégralRésumé :
The chloralkali industry is one of the largest single electricity consumers in the world, and electricity costs can account for about sixty per cent of the running costs of a modern plant. This article, which is based in part upon a paper given at the Third London International Chlorine Symposium, organised by the Society of Chemical Industry, the Chlorine Institute and the Royal Society of Chemistry, which was held in London during June, considers the use in membrane cells of noble metal coated cathodes developed by Johnson Matthey and indicates some of the savings that can result. These coated cathodes, which are being evaluated by a number of chloralkali plant manufacturers, appear to act in a catalytic manner to reduce the cathodic hydrogen overpotential and thus the energy consumption.

[Abstract] The 6th International Workshop on Rock Physics (6IWRP) was held A Coruña, Spain, between 13th and 17th of June, 2022. This meeting follows the track of the five successful encounters held in Golden (USA, 2011), Southampton (UK, 2013), Perth (Australia, 2015), Trondheim (Norway, 2017) and Hong Kong (China, 2019). The aim of the workshop was to bring together experiences allowing to illustrate, discuss and exchange recent advances in the wide realm of rock physics, including theoretical developments, in situ and laboratory scale experiments as well as digital analysis. While rock physics is at the core of the oil & gas industry applications, it is also essential to enable the energy transition challenge (e.g. CO2 and H2 storage, geothermal), ensure a safe and adequate use of natural resources and develop efficient waste management strategies. The topics of 6IWRP covered a broad spectrum of rock physics-related research activities, including: • Experimental rock physics. New techniques, approaches and applications; Characterization of the static and dynamic properties of rocks and fluids; Multiphysics measurements (NMR, electrical resistivity…); Deep/crustal scale rock physics. • Modelling and multiscale applications: from the lab to the field. Numerical analysis and model development; Data science applications; Upscaling; Microseismicity and earthquakes; Subsurface stresses and tectonic deformations. • Coupled phenomena and rock properties: exploring interactions. Anisotropy; Flow and fractures; Temperature effects; Rock-fluid interaction; Fluid and pressure effects on geophysical signatures. • The energy transition challenge. Applications to energy storage (hydrogen storage in porous media), geothermal resources, energy production (gas hydrates), geological utilization and storage of CO2, nuclear waste disposal. • Rock physics templates: advances and applications. Quantitative assessment; Applications to reser voir characterization (role of seismic wave anisotropy and fracture networks). • Advanced rock physics tools. Machine learning; application of imaging (X-ray CT, X-ray μCT, FIB-SEM…) to obtain rock proper ties. This book compiles more than 50 abstracts, summarizing the works presented in the 6IWRP by rock physicists from all over the world, belonging to both academia and industry. This book means an updated overview of the rock physics research worldwide.

Texte intégralRésumé :
The manufacturing industry uses a variety of materials, including pure metals, alloys and composites. Due to the inability of pure metals to meet the demands of modern products, a transition in materials from pure metals to composites is taking place. Composite materials are invented to attain the desired properties, including lightweight, high strength, creep resistance, high corrosion resistance, fatigue resistance, high-temperature resistance and high wear resistance. Natural plant fibers, such as flax, hemp, kenaf, jute, sisal, coir and cotton, are a reliable source for producing composites because they have various advantages over synthetic fibers, including cheaper cost, low specific gravity, biodegradability, lightweight, fewer health hazards, availability, low-grade greenhouse emissions and high flexibility. Natural fiber-reinforced polymer composites (NF-RPC) are commonly utilized in automotive applications because they are lighter in weight, resulting in lower fuel consumption and greenhouse gas emissions. The mechanical properties of NF-RPC, such as tensile strength, Young’s modulus, flexural strength, hardness and many others, are affected by several factors, for example, fiber aspect ratio, the weight percentage of fiber, different orientations of fiber, usage of the fabrication process, chemical compositions of fiber and different pre-treatments of fiber. Therefore, in this article, some specific applications, mechanical properties, fabrication techniques of NF-RPC, and methods to enhance the properties of natural fibers, have been discussed.

Texte intégralRésumé :
Meteorological big data has a wide geographical range, large space-time density, many data types and strong timeliness. It has become the requirement of the development of meteorological industry to quickly extract huge information and knowledge from big data to solve the problem of weather prediction. Based on the measured data of maximum one-hour rainfall from six representative rainfall stations in Wuhan from 1992 to 2021, the variation law, characteristic analysis and return period of different aging precipitation in Wuhan city in the past 30 years are analyzed. The results show that although the number of days of precipitation in Wuhan has increased year by year in the past 30 years, the days of rainstorm and more than rainstorm generally show a decreasing trend. The precipitation is mainly concentrated in spring (March-May) and summer (June-August), with the most in summer. The monthly precipitation is mainly concentrated in July, with the least precipitation in December. The maximum daily precipitation is between 55.1∼285.7mm, and the average maximum hourly precipitation of 122.4mm reaches 98.6mm. At last, based on the parameters of GEV distribution, the maximum hourly precipitation, maximum 3h, 6h, 12h, 24h precipitation, continuous hourly precipitation, maximum daily precipitation and maximum continuous daily precipitation are fitted, and the values of different recurrence periods are estimated.

The chapter presents the results of selecting the mode air travel by considering other modes of transportation to highlight public's preferences of mode transport. The approach was a cross-sectional study by employing a questionnaire to a sample size of N=500; the data were collected from January to June 2019. The main conclusion of the analysis was that the preferred mode of transport was by bus (59.6%) followed by air travel (23.6%). Some of the cons and pros of air travel are the following: 1) air travel is considered too expensive (90%); it is believed that 70% of Mexicans do not participate in air travel; 2) it may be perceived as unreliable due to the unexpected such as extreme weather, earthquakes (e.g., the 19 September earthquake in 2017) and volcanic activity (“Popocatepetl” volcano eruptions); 3) it is perceived as the fastest and most comfortable compared to bus and car transportation; 4) the benefits of the air transport industry in Mexico pre-COVID-19 pandemic were that it contributed to 3.05% of the country's GDP.

Texte intégralRésumé :
Türkiye’s Automobile Initiative Group was launched by bringing together the country’s leading or prominent groups in their fields under the leadership of the Union of Chambers and Commodity Exchanges of Türkiye (TOBB), Türkiye’s largest non-governmental organization. With the aim of creating a globally competitive mobility brand, of which the intellectual and industrial property rights would be owned by Türkiye, Togg was officially established on June 25, 2018, with Anadolu Group, BMC, Kök Group, Turkcell, Zorlu, and the Union of Chambers and Commodity Exchanges of Türkiye joining forces. The current share distribution of the company, which has a capital of TL 2 billion 643 million 774 thousand, is 23 percent for Anadolu Group, BMC, Turkcell and Zorlu Group, and 8 percent for the Union of Chambers and Commodity Exchanges of Türkiye. Togg describes itself as a user-centric and global mobility technology and services company. As of October 29, 2022, the brand has started serial production of the C-segment SUV, its first born electric, connected smart device, at the Gemlik Togg Technology Campus. Togg develops new services, new user experiences, and new business models in the field of mobility within the ecosystem to be created around the smart and connected device. Togg’s brand DNA can be summarized as “a character that is interested in what is going on in the world, constantly learning, forward-thinking, proactive and transforming its environment into a better place; passionate about its work, entrepreneurial, prioritizing competence, true to its word, caring about its own prestige and the prestige of those around it, striving to add value to every life it touches, stylish, and full of life”. Founded with the aim of creating its own automobile brand, which has been Türkiye’s dream for 60 years, and becoming the first global mobility brand of our country by pioneering the transformation of the Turkish automotive industry, Togg will break new ground with the technical and hardware features of the smart devices it will offer to the market, as well as the mobility ecosystem vision it has developed. The C-SUV model, which will be produced as Türkiye’s first born electric, zero-emission, and smart car, will be ahead of its competitors with features such as the longest wheelbase, the largest interior volume, the best acceleration performance, and the lowest total cost of ownership in its class. The first smart device of Togg, which set out to provide “outside-the-box mobility solutions” that can already respond to future smart transportation needs, will hit the road first in Türkiye in the first quarter of 2023 and then in Europe approximately 18 months after the completion of homologation tests. Togg has established the company Siro with Farasis, the world’s leading lithium ion battery manufacturer, to develop and manufacture its own battery technology and will offer energy storage solutions for mobility and stationary storage applications.

Texte intégralRésumé :
Additive manufacturing (AM) technologies can enable transitions to circular business models in production and repairs, but the uptake is not as rapid as some would like. This article describes the establishment of interest groups in support of AM in the Nordic countries, with a special focus on Norway. Action research conducted over four years detailed the process leading up to Norway's first national AM organization, established in June 2022. This development followed the emergence of similar organizations in Denmark, Finland and Sweden. The industry led approach taken in these countries is compared to the publicly funded AM cluster in Singapore, a country with a clear national aim of mastering AM. By highlighting similarities and differences between these countries, the article aims to provide regulators and policy makers new insights into the drivers and barriers connected to the twin green and digital transition to sustainable manufacturing.

Texte intégralRésumé :
In 2021, the Sri Lankan apparel manufacturing industry faced a severe downturn due to the COVID-19 pandemic and economic crises, highlighting the need for accurate sales predictions amid global supply chain disruptions. Traditional statistical models struggle to handle such crises, necessitating the exploration of machine learning methods for forecasting sales. This study aimed to identify the most effective predictive models for finished apparel goods sales, addressing data complexities like seasonality, trend, and stationarity, with a focus on enhancing decision-making in the industry. The dataset consisted of 128 weekly records of point-of-sale (POS) data for three specific apparel items sold in the US and manufactured in Sri Lanka, spanning from January 2021 to June 2023. Also, the inflation rate in the USA is used as an exogenous variable. Data preprocessing began with rationalization, followed by splitting it into training and testing sets. Two models, ARIMA and SARIMAX, were constructed using the training data to analyze the time series. Model performance was assessed using Mean Square Error (MSE), with the goal of generating future sales predictions. The results indicated that the ARIMA model outperformed SARIMAX, exhibiting significantly lower MSE values. This outcome suggests that ARIMA is the superior model for forecasting sales in this context. Future research aims to validate this result by incorporating additional datasets, ensuring the continued effectiveness of the ARIMA model in predicting apparel sales. In conclusion, this study highlights the critical role of advanced machine learning techniques, in improving sales predictions for the Sri Lankan apparel manufacturing industry. By addressing data complexities and employing robust validation methods, this research contributes to more precise planning and decision-making, essential for navigating disruptions in the global supply chain and economic uncertainties.

Roberts, Ruby, Rhona Flin et Luca Corradi. « Accelerating Technology Adoption : A Benchmarking Study of Organisational Innovation Adoption Culture in Upstream Oil and Gas ». Dans SPE Offshore Europe Conference & Exhibition. SPE, 2021. http://dx.doi.org/10.2118/205448-ms.
Texte intégralRésumé :
Abstract Working towards a net zero future requires change and adaptation from us all. Innovation offers many potential solutions on how to successfully make that change within the oil and gas industry. Consequently, maximising the value that technological innovation presents is vital for delivering a sustainable net zero. Yet, the oil and gas industry has developed a reputation for being conservative and reluctant to adopt new technology, with companies sometimes referred to as "fast followers". In recent years, the industry has begun to change with an incremental increase in innovation activities. Despite these efforts, and a need to accelerate innovation, there appears to be a resistance to adopt new technology. Evidence from O&G industry bodies indicate that psychological factors play a key role in technology adoption; not surprisingly, as workers, managers, investors, and regulators can all have a powerful influence on an organisation's receptivity to new technology. Recent research has provided insight into the psychological factors that influence technology uptake decisions in the oil and gas industry. Through a series of studies, the psychological technology adoption framework (P-TAF) was developed which outlined the 15 key psychological factors that influence technology adoption decisions. These are organised into 6 categories: personality, attitudes, motivations, cognitive factors, social factors, and organisational level factors. The work emphasised the influence that overarching organisational culture can have on how people respond to and introduce technology within their company. Whilst technology readiness levels are commonly applied to start-ups and their innovations, less is known about the readiness culture which facilitates innovation uptake. To bridge this gap, a preliminary measure of organisational innovation adoption culture was developed as based upon the previous psychological research, empirical innovation measures, and organisational culture models. This was piloted as an online survey with 36 people working in the technology space in O&G in June 2020. These results were used to later refine the culture measure to develop a 33-item scale consisting of eight categories. This new measure was deployed as part of an industry benchmarking study of innovation adoption culture within O&G consisting of 82 managers from 12 companies and in December 2020. Participating organisations were given the opportunity to receive a snapshot of their technology adoption culture. An overview of the measure and a summary of survey results will be given during the presentation as well as recommendations on how to support an innovation adoption culture. A considerable volume of new technology needs to be developed and adopted to be able to reach net zero and understanding the psychological and cultural barriers is imperative to delivering that.

Martinez, Eloy, David Tyrell et John Zolock. « Rail-Car Impact Tests With Steel Coil : Car Crush ». Dans IEEE/ASME 2003 Joint Rail Conference. ASMEDC, 2003. http://dx.doi.org/10.1115/rtd2003-1656.
Texte intégralRésumé :
Two grade-crossing impact tests were conducted in June 2002 at the Federal Railroad Administration’s (FRA’s) Transportation Technology Center in Pueblo, Colorado as part of the FRA’s research into passenger equipment crashworthiness. In both of these tests a cab car moving at approximately 14 mph impacted a standing coil of steel supported by a frangible table. The coil was positioned such that the left-side corner post of the cab car sustained the brunt of the impact. The cars were instrumented to measure the accelerations of the carbody, the displacements of the suspensions, the displacements of the corner posts, and the strains in selected structural members. The coil was instrumented to measure its three-dimensional acceleration, including yaw, pitch, and roll. On-board and wayside high-speed film and video cameras were used to record the impact. On June 4, 2002 a cab car compliant with general industry practice circa 1999 was tested and on June 7, 2002 a cab car compliant with current FRA regulations and American Public Transportation Association (APTA) Standards and Recommended Practices for Rail Passenger Equipment was tested. The tests themselves were conducted in response to a recommendation from the APTA Passenger Rail Equipment Safety Standards (PRESS) Committee to measure the crashworthiness performance of alternative cab car end structures. During the test of the 1990’s design, the corner post failed, eliminating the survival space for the operator. During the test of the state-of-the-art design cab car, the corner post remained attached and deformed less than 9 inches, preserving space for the operator. Prior to the test, crush analyses were conducted to determine the force/crush characteristics of the two end structure designs, as well as their modes of deformation. Collision dynamics analyses were also conducted to determine the extent of crush and the gross motion of the car and coil. This paper describes the analysis of the crush behaviors of the two different end structure designs. A companion paper describes the results of the collision dynamics analyses. The crush of the cars was analyzed using detailed finite-element models. The impact end of each car was modeled, including approximately 1/4 of the length of the car. The back end of the cab car model was fixed, and its end structure was impacted by an initially moving cylinder with the same mass and dimensions as the steel coil used in the tests. Prior to the tests, runs were made with the models with and without material failure. This approach allowed calculation of an upper bound and a lower bound on the force/crush characteristics. The pre-test predictions of the analysis of the state-of-the art car including material failure very closely match the results of the test for the force/crush characteristic, strains at the measured locations, the geometry of the deformed structure, and the locations and extent of material failure. The pre-test predictions of the analysis of the 1990’s design also closely match the test measurements, however, the extent of material failure predicted was slightly less than observed in the test; failure of the corner post was predicted to occur at a speed of a 1.6 mph (approximately 10%) greater than the test speed. A more sophisticated implementation of the material failure modeling helped bring the model results into very close agreement with the test measurements.

Texte intégralRésumé :
Three recent accidents involving the release of hazardous material have focused attention on the structural integrity of railroad tank cars: (1) Minot, ND, on January 18, 2002; (2) Macdona, TX, on June 28, 2004; and (3) Graniteville, SC, on January 6, 2005. Each of these accidents resulted in fatalities. Research is being conducted to develop strategies for improving railroad tank cars so they can maintain tank integrity in severe accidents. A collaborative effort called the Next Generation Rail Tank Car (NGRTC) Project intends to use these research results to help develop improved tank car designs. Dow Chemical Company, Union Pacific Railroad, and Union Tank Car Company are the industry sponsors of the NGRTC Project. The Federal Railroad Administration (FRA) and Transport Canada participate in the NGRTC project through Memoranda of Cooperation. FRA and the Pipeline and Hazardous Materials Safety Administration intend to use these research results to support rulemaking. The approach taken in performing this research is to define the collision conditions of concern, to evaluate the behavior of current design equipment in these scenarios, and to develop alternative strategies for increasing the maximum impact speed for which tank integrity is maintained. The accident scenarios have been developed from a review of accidents and are intended to bound the range of main-line accidents that can lead to a release of hazardous material from a tank car. The accident scenarios and collision modes have been used to define car-to-car impact scenarios. These car-to-car impact scenarios define the conditions under which the commodity must be contained. The impact scenarios are being used to evaluate the integrity of current design and improved design tank cars. Full-scale impact tests are also being conducted, to help validate modeling of the baseline equipment. The models have been refined based on the test results. The models are now being applied to develop the improved equipment designs. This paper describes the overall research framework and provides an overview of the research done to date, as well as the planned efforts.

Texte intégralRésumé :
In India, the construction industry is the second-largest employer, with 51 million workers currently employed. Contracting and subcontracting has contributed to the rise of intermediary labor contractors, who provide migrants with information about labor markets and bring them to construction sites for work. Engagement in physically demanding low-skill jobs, low wages, harsh working conditions, and often deplorable living arrangements characterize the lives of many migrant construction workers. The Population Council, in partnership with the Global Fund to End Modern Slavery and the Norwegian Agency for Development Cooperation, undertook a qualitative study to explore the nature of the labor supply chain in the construction industry and the relationship between workers, micro-contractors, other contractors, and construction firms/companies. The study also explored vulnerabilities faced by migrant construction workers, perceptions of workers and micro-contractors about ethical recruitment and employment practices, and challenges faced by micro-contractors in following these ethical recruitment and employment practices. Twenty-five micro-contractors and 236 workers were interviewed from June to August 2022 in construction sites in Bengaluru and Delhi in India.

Texte intégralRésumé :
Until now, amount of inter-country trade within South Asian nations have been low. While similarities in exports profile can be seen as a reason for this low value of trade it might not be a valid one, especially in presence of growing South Asian income. Intra-industry trade theory suggests that complementarity might actually increase trade in presence of a rising income. There can be other important factors, such as, trade costs. Using an augmented gravity model in a panel framework the authors try to identify the components of trade costs that might have resulted in lower inter-country South Asian trade. This paper was prepared for the Latin America/Caribbean and Asia/Pacific Economics and Business Association (LAEBA)'s 4th Annual Meeting held in Lima, Peru, on June 17, 2008.

Payment Systems Report - June of 2020. Banco de la República de Colombia, février 2021. http://dx.doi.org/10.32468/rept-sist-pag.eng.2020.
Texte intégralRésumé :
With its annual Payment Systems Report, Banco de la República offers a complete overview of the infrastructure of Colombia’s financial market. Each edition of the report has four objectives: 1) to publicize a consolidated account of how the figures for payment infrastructures have evolved with respect to both financial assets and goods and services; 2) to summarize the issues that are being debated internationally and are of interest to the industry that provides payment clearing and settlement services; 3) to offer the public an explanation of the ideas and concepts behind retail-value payment processes and the trends in retail payments within the circuit of individuals and companies; and 4) to familiarize the public, the industry, and all other financial authorities with the methodological progress that has been achieved through applied research to analyze the stability of payment systems. This edition introduces changes that have been made in the structure of the report, which are intended to make it easier and more enjoyable to read. The initial sections in this edition, which is the eleventh, contain an analysis of the statistics on the evolution and performance of financial market infrastructures. These are understood as multilateral systems wherein the participating entities clear, settle and register payments, securities, derivatives and other financial assets. The large-value payment system (CUD) saw less momentum in 2019 than it did the year before, mainly because of a decline in the amount of secondary market operations for government bonds, both in cash and sell/buy-backs, which was offset by an increase in operations with collective investment funds (CIFs) and Banco de la República’s operations to increase the money supply (repos). Consequently, the Central Securities Depository (DCV) registered less activity, due to fewer negotiations on the secondary market for public debt. This trend was also observed in the private debt market, as evidenced by the decline in the average amounts cleared and settled through the Central Securities Depository of Colombia (Deceval) and in the value of operations with financial derivatives cleared and settled through the Central Counterparty of Colombia (CRCC). Section three offers a comprehensive look at the market for retail-value payments; that is, transactions made by individuals and companies. During 2019, electronic transfers increased, and payments made with debit and credit cards continued to trend upward. In contrast, payments by check continued to decline, although the average daily value was almost four times the value of debit and credit card purchases. The same section contains the results of the fourth survey on how the use of retail-value payment instruments (for usual payments) is perceived. Conducted at the end of 2019, the main purpose of the survey was to identify the availability of these payment instruments, the public’s preferences for them, and their acceptance by merchants. It is worth noting that cash continues to be the instrument most used by the population for usual monthly payments (88.1% with respect to the number of payments and 87.4% in value). However, its use in terms of value has declined, having registered 89.6% in the 2017 survey. In turn, the level of acceptance by merchants of payment instruments other than cash is 14.1% for debit cards, 13.4% for credit cards, 8.2% for electronic transfers of funds and 1.8% for checks. The main reason for the use of cash is the absence of point-of-sale terminals at commercial establishments. Considering that the retail-payment market worldwide is influenced by constant innovation in payment services, by the modernization of clearing and settlement systems, and by the efforts of regulators to redefine the payment industry for the future, these trends are addressed in the fourth section of the report. There is an account of how innovations in technology-based financial payment services have developed, and it shows that while this topic is not new, it has evolved, particularly in terms of origin and vocation. One of the boxes that accompanies the fourth section deals with certain payment aspects of open banking and international experience in that regard, which has given the customers of a financial entity sovereignty over their data, allowing them, under transparent and secure conditions, to authorize a third party, other than their financial entity, to request information on their accounts with financial entities, thus enabling the third party to offer various financial services or initiate payments. Innovation also has sparked interest among international organizations, central banks, and research groups concerning the creation of digital currencies. Accordingly, the last box deals with the recent international debate on issuance of central bank digital currencies. In terms of the methodological progress that has been made, it is important to underscore the work that has been done on the role of central counterparties (CCPs) in mitigating liquidity and counterparty risk. The fifth section of the report offers an explanation of a document in which the work of CCPs in financial markets is analyzed and corroborated through an exercise that was built around the Central Counterparty of Colombia (CRCC) in the Colombian market for non-delivery peso-dollar forward exchange transactions, using the methodology of network topology. The results provide empirical support for the different theoretical models developed to study the effect of CCPs on financial markets. Finally, the results of research using artificial intelligence with information from the large-value payment system are presented. Based on the payments made among financial institutions in the large-value payment system, a methodology is used to compare different payment networks, as well as to determine which ones can be considered abnormal. The methodology shows signs that indicate when a network moves away from its historical trend, so it can be studied and monitored. A methodology similar to the one applied to classify images is used to make this comparison, the idea being to extract the main characteristics of the networks and use them as a parameter for comparison.
