This article presents a new framework named ANDROSCANREG (Android Permissions Scan Registry) that allows to extract and analyze the requested permissions in an Android application via a decentralized and distributed system. This framework is based on the emerging technology Blockchain whose potential is approved in the matter of transparency, reliability, security and availability without resorting to a central processing unit judged of trust. ANDROSCANREG consists of two Blockchains, the first one (PERMBC) will handle analysis, validation and preparation of the raw results so that they will persist in the second Blockchain of Bitcoin already existing (BTCBC), which will assume the role of a Registry of recovered permissions and will save the permissions history of each version of the applications being scanned via financial transactions, whose wallet source, recipient wallet and transaction value have a precise meaning. An example of a simulation will be presented to describe the different steps, actors, interactions and messages generated by the different entity of ANDROSCANREG.

Economic globalization refers to the intensification and stretching of economic connections across the globe. ‘The economic dimension of globalization’ gives a brief history of the emergence of the global economic order. Towards the end of the Second World War, the Bretton Woods Conference laid the foundations for institutions such as the International Monetary Fund, the World Bank, and World Trade Organization. In the 1980s, rising neoliberalism led to the deregulation of financial transactions. Significant developments include the internationalization of trade, the increasing power of transnational corporations, and the enhanced role of international economic institutions. We have recently experienced setbacks like the 2007–10 recession and the slowdown of the Chinese economy.

The article presents an algorithm for using parallel computing technology using CUDA and blockchain technology to recover the password for an encrypted PDF file. The analysis and comparison of the computational speed using a graphics processor (GPU) and a central processing unit (CPU) are carried out. The testing of the implemented algorithm is carried out. A statistical analysis of the results of experimental studies is presented.

The evolution of pantropically distributed clades has puzzled palaeo- and neontologists for decades regarding the different hypotheses about where they originated. In this study, we explored how a pantropical distribution arose in a diverse clade with a rich fossil history: the avian order Coraciiformes. This group has played a central role in the debate of the biogeographical history of Neoaves. However, the order lacked a coherent species tree to inform study of its evolutionary dynamics. Here, we present the first complete species tree of Coraciiformes, produced with 4858 ultraconserved elements, which supports two clades: (1) Old World-restricted bee-eaters, rollers and ground-rollers; and (2) New World todies and motmots, and cosmopolitan kingfishers. Our results indicated two pulses of diversification: (1) major lineages of Coraciiformes arose in Laurasia approximately 57 Ma, followed by independent dispersals into equatorial regions, possibly due to tracking tropical habitat into the lower latitudes—the Coracii (Coraciidae + Brachypteraciidae) into the Afrotropics, bee-eaters throughout the Old World tropics, and kingfishers into the Australasian tropics; and (2) diversification of genera in the tropics during the Miocene and Pliocene. Our study supports the important role of Laurasia as the geographical origin of a major pantropical lineage and provides a new framework for comparative analyses in this charismatic bird radiation.

Throughout the short history of interactive digital music, there have been frequent calls for a new language of interaction that incorporates and acknowledges the unique capabilities of the computational medium. In this paper we suggest that a conceptualisation of possible modes of performance–time interaction can only be sensibly approached in light of the ways that computers alter the social–artistic interactions that are precursive to performance. This conceptualisation hinges upon a consideration of the changing roles of composition, performer and instrument in contemporary practice. We introduce the termbehavioural objectto refer to software that has the capacity to act as the musical and social focus of interaction in digital systems. Whilst formative, this term points to a new framework for understanding the role of software in musical culture. We discuss the potential for behavioural objects to contribute actively to musical culture through two types of agency:performative agencyandmemetic agency.

The key financial transactions in U.S. healthcare occur when the provider sends a claim to the payer and the payer adjudicates the claim. This chapter first explains the history of electronic data interchange (EDI) and then shows the powerful, costsaving impact that it can have on healthcare. One bottleneck to EDI in healthcare has been the lack of standardization. This problem was addressed with a law passed in 1996, with which the healthcare industry was still grappling a decade later. The standardization of these transactions will be explored in detail in this chapter. After that, a different aspect of provider-payer transactions is examined, namely, the temptation to cheat and the role of software in combating fraud.

SUMMARY Blockchain offers a drastically new way to record, process, and store financial transactions and information, and has the potential to fundamentally change the landscape of the accounting profession and reshape the business ecosystem. In this article, we introduce two types (i.e., permissionless and permissioned) of blockchain and lay out their technological features. We further discuss implications of blockchain to auditing and elaborate on opportunities and challenges of the two types of blockchain to auditors. We conclude by making specific recommendations for auditors to adapt, adjust, and elevate themselves to the role of strategic partners in blockchain implementation.

While the terms « authorization » and « consent » are commonly used in juridical language, their definition end precise meaning are not acknowledged by the Quebec legislator. In fact the two terms are often used interchangeably. Both the legislative history of the first paragraph of article 20 of the Civil Code, an article which provides protective measures for the discerning minor entering into a medical contract, and the reforms suggested by the Civil Code Revision Office, demonstrate this confusion as to the proper juridical terms and as to the role of the parental and judicial sanction. The author maintains that the term « consent » is not applicable to the juridical role of the parent of judge.

The microprocessor—a computer central processing unit integrated onto a single microchip—has come to dominate computing across all of its scales from the tiniest consumer appliance to the largest supercomputer. This dominance has taken decades to achieve, but an irresistible logic made the ultimate outcome inevitable. The objectives of this Perspective paper are to offer a brief history of the development of the microprocessor and to answer questions such as: where did the microprocessor come from, where is it now, and where might it go in the future?
