The Creation

AbstractBlockchain technology has enabled a new kind of distributed systems. Beyond its early applications in Finance, it has also allowed the emergence of novel new ways of governance and coordination. The most relevant of these are the so-called Decentralized Autonomous Organizations (DAOs). DAOs typically implement decision-making systems to make it possible for their online community to reach agreements. As a result of these agreements, the DAO operates automatically by executing the appropriate portion of code on the blockchain network (e.g., hire people, delivers payments, invests in financial products, etc). In the last few years, several platforms such as Aragon, DAOstack and DAOhaus, have emerged to facilitate the creation of DAOs. As a result, hundreds of these new organizations have appeared, with their communities interacting mediated by blockchain. However, the literature has yet to appropriately explore empirically this phenomena. In this paper, we aim to shed light on the current state of the DAO ecosystem. We review the three main platforms nowadays (Aragon, DAOstack, DAOhaus) which facilitate the creation and management of DAOs. Thus, we introduce their main differences, and compare them using quantitative metrics. For such comparison, we retrieve data from both the main Ethereum network (mainnet) and a parallel Ethereum network (xDai). We analyze data from 72,320 users and 2,353 DAO communities in order to study the three ecosystems across four dimensions: growth, activity, voting system and funds. Our results show that there are notable differences among the DAO platforms in terms of growth and activity, and also in terms of voting results. Still, we consider that our work is only a first step and that further research is needed to better understand these communities, and evaluate their level of accomplishment in reaching decentralized governance.

Abstract Blockchain technology has prompted new ways of governance and coordination. Such forms receive the name of Decentralized Autonomous Organizations (DAOs). DAOs typically implement decision-making systems to make possible for the community to reach agreements. As a result of the agreements the DAO automatically operates (e.g., hire people, payments, invest in financial products, etc.) by executing code on the blockchain. In the last few years, several platforms such as Aragon, DAOstack and DAOhaus, have emerged to facilitate the creation of DAOs. As a result, hundreds of this new organizations have appeared and are interacting in the blockchain. However, little is known about them. In this paper, we want to shed light on them. We will review the three main platforms (Aragon, DAOstack, DAOhaus) that make possible to create and manage a DAO. We introduce the main differences between these platforms, and we finally compare them numerically. For the comparison we retrieve data from both the main Ethereum network (mainnet) and a parallel Ethereum network (xDai). We analyze data from 72,320 users from 2,353 DAO communities to study the three ecosystems along four dimensions: growth, activity, voting system and funds. Our results show that there are notable differences among the DAO platforms in terms of growth and activity, but also interms of voting results. Still we consider that our work is only a first step and that further research is needed to better understand these communities and to help them to accomplish their aim of decentralized governance.

Purpose This paper attempts to fill the gap that exists in research regarding 20th-century heritage and its social appreciation. The purpose of this paper is to explore different ways of evaluating the heritage value and tourism potential and to propose an innovative model validated in the Zarzuela Hippodrome as an example of cultural asset from 20th century with important economic, social, cultural, aesthetic and architectural aspects. Design/methodology/approach This study opted for an interpretation of heritage from an ecosystem, integrating and global paradigm, understanding the asset as a set of resources that interact with each other, generating a common and enriched tourist experience among all the elements that make it up. From this perspective, it is conceived that by modifying one of the elements, the whole (tourist) ecosystem will be equally influenced. On the other side, it was incorporated non-parametric techniques based on the implementation of surveys for the validation of the tool to the case study of the Zarzuela hippodrome. Findings The results suggest that the hippodrome's internal values have been evaluated very positively, while its external values are low. Through this study, the paper has identified several weaknesses that impede its functioning as a viable “tourist product.” The distance from the city center, the lack of available information and the scarce diffusion and tourism promotion are its main weaknesses. The proposed analysis tool reveals the importance of the active participation of visitors to evaluate cultural assets through the combination of aspects related to the conservation of cultural assets and, in turn, elements that encourage their commodification as tourist products, break down barriers between these two disciplines. Research limitations/implications The management tool proposed in this study can be used to underpin the creation of tourism experiences in cultural or heritage assets by diagnosing the current state of its tourist potential, quantifying its value in relation to the visitors’ perception and making visible those problematic aspects to develop actions to solve them. Although the present study is support for future research, as well as for improving the marketing of heritage in tourist settings, an in-depth analysis of the technical elements of heritage, as well as of its intervention (if applicable), will be necessary for the managers who want to use the tool. Social implications One of the most differentiating characteristics between the construction typology of 20th-century historical buildings is perhaps the scarcity of decorative ornamentation, with exposed concrete being the main surface coating. Many of these constructions have an important cultural and historical relevance, however, the social perception, as regards its consideration as architectural and artistic heritage seems to reflect discordant aspects. This study provides support as a decision-making tool to determine the existing valuation of a building and how to enhance it. Originality/value This study takes steps toward the creation of a model that supports decision-makers and owners of cultural assets through a measurement system that makes it possible to quantify and determine the current state of tourism use through the social evaluation of heritage criteria. It defines which are the elements that favor the resilience of the property or, on the contrary, which are those that undermine its enhancement.

The article examines the current state of receivables management, identifies the main problems and suggests ways to overcome them, including accounting. The research methodology is based on general scientific methods of cognition: historical, logical, systemic, induction, deduction, analysis, synthesis; methods of statistical data processing, classification, grouping. Emphasis is placed on the growth of receivables and its consistently high share in the current assets of domestic enterprises over the past three years, which necessitates the development of measures to optimize its management. Modern software, including the subsystem "Accounting" "1C: Enterprise 8" does not contain a separate complex for accounting for receivables and the provision for doubtful debts. This determines the expediency of accrual of the provision for doubtful debts in the subsystem "Accounting" in the document "Debt Adjustment", which is designed to adjust the debt of mutual settlements with counterparties and is responsible for the function of debt write-off. It is proved that the process of receivables management in the conditions of digitalization can be optimized by integrating communication and network technologies. Integration processes provide the formation of a common information environment at the micro and macro levels with access to internal and external users of accounting information. It is advisable to integrate the function of information exchange with a single database of counterparties in modern software products for accounting automation. This will allow you to obtain information about counterparties, the existence of contractual relations, the state of receivables and the procedure for its repayment. The single database will provide an opportunity for information exchange between suppliers, customers, banking institutions, legal and factoring organizations, government agencies of the fiscal service and statistics. All these measures will optimize the process of managing receivables in terms of the use of information technology. The prospect of further research is to study the information support of receivables management in the application of blockchain technology.

The basic principles and current state of topographic mapping of the territory of Ukraine are considered. Prior to the proclamation of Ukraine's independence, its territory was covered by topographic maps in the scale of 1:10 000 to 1: 1 000 000, created by the Main Department of Geodesy and Cartography under the USSR Council of Ministers and the Military Topographic Service of the USSR Armed Forces. The interaction of these departments in topographic mapping is highlighted. The topographic study of Ukrainian territory as of 1991 is analyzed in detail. Today the content of most topographic maps of scales from 1:10 000 to 1: 200 000 is characterized by "aging" of information and does not correspond to the current state of the area. The unsatisfactory state of topographic study of the territory led to the unclaimed topographic maps with much outdated information for consumers, and for the military it very difficult to perform combat tasks. The needs of current topographic information users require a significant improvement in topographic maps content. Since the mid-1990s, the creation of national geospatial data infrastructures has become crucial for providing spatial information to the state and society. The basic principles and general requirements for the creation and updating of state topographic maps are now defined by the "Procedure for national topographic and thematic mapping" (2013). The adoption of the Law of Ukraine "On the National Infrastructure of Geospatial Data", giving a powerful impetus to topographic mapping, poses a responsible task of organizational and regulatory and technical support of this process. The issue of obtaining topographic maps from the topographic database requires scientific and technical elaboration, development of appropriate normative and technical documents (guides, principles, instructions, symbols, etc.).
