This study reviewed and unveiled the economic sizes and managing systems in aquaculture production. The focus had been on developing new technologies and management systems in aquaculture production that can produce fish food on an economically competitive basis while still maintaining environmental health. The technique of recirculating aquaculture system (RAS) had been discussed. Economic issues such as: adequately available quality water, economic sizes, management issues, financial capabilities, various investment options, species selection, cost of production, capitalization cost of unit process, cost of pumping and bio-filtration, gas stripping and pH control, solid wastes removal, economically competitive scale, labor requirements as wellas predicted cost of production. The economic comparison of broilers and catfish production were evaluated. Also, challenges against the effective aquaculture technological application and the prospects to economic realities and management systems in aquaculture production were also highlighted. It could be concluded that economic realities and management of RAS is the soft and live wire in aquacultural development especially in developing countries like Nigeria. It is therefore, recommended that fish farmers need to engage and be trained on the use of this new fish production technology for increase production and economy benefits.

This chapter discusses a theoretical approach to the adoption of electronic resource management systems in Nigeria university libraries. The nature of electronic resources calls for a special way of managing it thereby the invention and adoption of electronic resource management systems (ERMS). However, observation revealed that Nigerian libraries have yet to largely adopt it. It is therefore necessary to theoretically outline the factors promoting adoption of new technologies, in order for Nigerian libraries to take a cue. This chapter proposes a theoretical approach to the adoption of ERMS in Nigerian libraries.

AbstractRecirculating aquaculture technology, which includes aquaponics, has been under development for the past 40 years from a combination of technologies derived from the wastewater treatment and aquaculture sectors. Until recently, recirculating aquaculture systems (RAS) farms have been relatively small compared with other types of modern aquaculture production. The last two decades have seen a significant increase in the development of this technology, with increased market acceptance and scale. This chapter provides a brief overview of the history, water quality control processes, new developments and ongoing challenges of RAS.

The constant innovation in new technologies and the increase in the use of computing devices in different areas of the society have contributed to a digital transformation in almost every sector. This digital transformation has also reached the world of education, making it possible for members of the educational community to adopt Learning Management Systems (LMS), where the digital contents replacing the traditional textbooks are exploited and managed. This article aims to study the relationship between the type of computing device from which students access the LMS and how affects their performance. To achieve this, the LMS accesses of students in a school comprising from elementary to bachelor’s degree stages have been monitored by means of different computing devices acting as sensors to gather data such as the type of device and operating system used by the students.The main conclusion is that students who access the LMS improve significantly their performance and that the type of device and the operating system has an influence in the number of passed subjects. Moreover, a predictive model has been generated to predict the number of passed subjects according to these factors, showing promising results.

The development of quality control and risk management systems is a priority for any industry and especially for the corporate insurance industry. Defective product and work incidents represent 14% of the total number of insurance claims, serving as the main loss of liability for businesses. According to a Allianz Global Corporate and Specialty press release, the cyber risks and impact of new technologies will have an increasing influence on the landscape of corporate losses in the coming years. Our results from this study conclude that the emerging business risks for the next 3–4 years are as follows: cyber incidents, 48%; new technologies, 30%; and changes in legislations/regulations, 28% (i.e., the present pandemic cause by COVID-19, the Brexit, trade wars, and tariffs etc.).

Things are valuable because they are scarce. The more abundant they become,they cheaper they become. But a series of technological changes is underwaythat promises to end scarcity as we know it for a wide variety of goods.The Internet is the most obvious example, because the change there isfurthest along. The Internet has reduced the cost of production anddistribution of informational content effectively to zero. In many cases ithas also dramatically reduced the cost of producing that content. And ithas changed the way in which information is distributed, separating thecreators of content from the distributors.More recently, new technologies promise to do for a variety of physicalgoods and even services what the Internet has already done for information.3D printers can manufacture physical goods based on any digital design.Synthetic biology has automated the manufacture not just of copies ofexisting genetic sequences but any custom-made gene sequence, allowinganyone who want to create a gene sequence of their own to upload thesequence to a company that will “print” it using the basic building blocksof genetics. And advances in robotics offer the prospect that many of theservices humans now provide can be provided free of charge bygeneral-purpose machines that can be programmed to perform a variety ofcomplex functions. While none of these technologies are nearly as far alongas the Internet, they share two essential characteristics with theInternet: they radically reduce the cost of production and distribution ofthings, and they separate the informational content of those things (thedesign) from their manufacture. Combine these four developments – theInternet, 3D printing, robotics, and synthetic biology – and it is entirelyplausible to envision a not-too-distant world in which most things thatpeople want can be downloaded and created on site for very little money.The role of IP in such a world is both controverted and criticallyimportant. IP rights are designed to artificially replicate scarcity whereit would not otherwise exist. In its simplest form, IP law takes publicgoods that would otherwise be available to all and artificially restrictstheir distribution. It makes ideas scarce, because then we can bring theminto the economy and charge for them, and economics knows how to deal withscarce things. So on one view – the classical view of IP law – a world inwhich all the value resides in information is a world in which we need IPeverywhere, controlling rights over everything, or no one will get paid tocreate. That has been the response of IP law to the Internet so far.But that response is problematic for a couple of reasons. First, it doesn’tseem to be working. By disaggregating creation, production, anddistribution, the Internet democratized access to content. Copyright ownershave been unable to stop a flood of piracy with 50,000 lawsuits, a host ofnew and increasingly draconian laws, and a well-funded public educationcampaign that starts in elementary school. Second, even if we could use IPto rein in all this low-cost production and distribution of stuff, we maynot want to. The point of IP has always been, not to raise prices andreduce consumption for its own sake, but to encourage people to createthings when they otherwise wouldn’t. More and more evidence casts doubt onthe link between IP and creation, however. Empirical evidence suggests thatoffering money may actually stifle rather than drive creativity amongindividuals. Economic evidence suggests that quite often it is competition,not the lure of monopoly, that drives corporate innovation. The Internetmay have spawned unprecedented piracy, but it has also given rise to thecreation of more works of all types than ever before in history, often bymultiple orders of magnitude.Far from necessitating more IP protection, then, the development ofcost-reducing technologies may actually weaken the case for IP. If peopleare intrinsically motivated to create, as they seem to be, the easier it isto create and distribute content, the more content is likely to beavailable even in the absence of IP. And if the point of IP is to encourageeither the creation or the distribution of that content, cost-reducingtechnologies may actually mean we have less, not more, need for IP.IP rights are a form of government regulation of market entry and marketprices. We regulated all sorts of industries in the 20th century, fromairlines to trucking to telephones to electric power, often because wecouldn’t conceive of how the industry could survive without the governmentpreventing entry by competitors. Towards the end of that century, however,we experimented with deregulation, and it turned out that the market couldprovide many of those services better in the absence of governmentregulation. The same thing may turn out to be true of IP regulation in the21st century. We didn’t get rid of all regulation by any means, and wewon’t get rid of all IP. But we came to understand that the free market,not government control over entry, is the right default position in theabsence of a persuasive justification for limiting that market. Theelimination of scarcity will put substantial pressure on the law to do thesame with IP.A world without scarcity requires a major rethinking of economics, much asthe decline of the agrarian economy did in the 19th century. How will oureconomy function in a world in which most of the things we produce arecheap or free? We have lived with scarcity for so long that it is hard evento begin to think about the transition to a post-scarcity economy. IP hasallowed us to cling to scarcity as an organizing principle in a world thatno longer demands it. But it will no more prevent the transition thanagricultural price supports kept us all farmers. We need a post-scarcityeconomics, one that accepts rather than resists the new opportunitiestechnology will offer us. Developing that economics is the great task ofthe 21st century.

This research aims to analyze the amount of income earned by farmers from cocoa farming. This research was conducted from May to June 2013 in Siontapina village of Lasalimu Sub-district of Buton Regency. The research sample is determined by sample random techniques (Simple random sampling method) with 30 people. Research data obtained through direct interviews with farmer respondents using a questionnaire. While secondary data is obtained from the village office/administrative and related institutions were analyzed descriptively and quantitatively used to determine the level of income by the formula : N1 = TR- TC, TR = P x Q, TC = TFC + TVC, comparative analysis: Revenue - cost ratio for comparing the difference between the value of production and the cost of production by the formula RC ratio : R/C = Revenue (TR) / Total Cost (TC). The results showed that the income earned by farmers from cocoa farming with land area ranges between 1 to 3 ha of IDR 8,109,000 - 35,437,000/year, with income per capita monthly average IDR 675,750,00 so that Siontapina village had not been considered poor, the average income earned by farmers in cocoa farming with land area- average of 2,05 hectares of IDR 18,426,767/year. Cocoa farming by farmers still does because based on the results of feasibility analysis obtained a value of 5.7. This illustrates that every cost IDR 1.00 incurred by farmers will gain acceptance by IDR 5.7. So, farmers are expected to carry cocoa farming is more responsive and responsive to the presence of new technologies that can increase cocoa production.   Keywords: revenue, cost of production, cocoa.

The development of the ideology of sustainable development stimulated the emergence of companies’ Performance Management Systems with an emphasis on the environmental aspects of their activities. Benchmarking, as a modern management tool, is often used for competitive analysis and setting development goals. This study’s scientific problem is to assess the feasibility of applying benchmarking studies to assess the global industry’s environmental aspects. The purpose of the study is to identify the prerequisites for using benchmarking to improve environmental performance, as well as to identify best practices among world-leading companies. For benchmarking, a logical information model is proposed in the study. On its basis, eight world leaders were selected, trends in the industry’s development were analysed, and reference values of environmental indicators were established. For environmental performance assessment, it is proposed to use such indicators as greenhouse gas emissions, energy consumption, material efficiency, environmental management systems. Comparative benchmarking analysis of world leaders and 16 largest Ukrainian companies allowed determining the reserves for increasing environmental performance. The directions for increasing environmental performance are Investment in resource-saving technologies, production of higher value-added products, investments in energy-saving and new technologies, improvement of management systems, and certification. These ideas are complemented by recommendations for improving environmental performance, based on the Circular Economy Concept’s philosophy and Industry 4.0. The study’s practical significance is that Ukrainian companies can use their results to achieve higher environmental and economic outcomes.
