Smart contracts vulnerabilities: a call for blockchain software engineering?

Abstract: Smart Contracts have gained tremendous popularity in the past few years, to the point that billions of US Dollars are currently exchanged every day through such technology. However, since the release of the Frontier network of Ethereum in 2015, there have been many cases in which the execution of Smart Contracts managing Ether coins has led to problems or conflicts. Compared to traditional Software Engineering, a discipline of Smart Contract and Blockchain programming, with standardized best practices that can help solve the mentioned problems and conflicts, is not yet sufficiently developed. Furthermore, Smart Contracts rely on a non-standard software life-cycle, according to which, for instance, delivered applications can hardly be updated or bugs resolved by releasing a new version of the software. In this paper we advocate the need for a discipline of Blockchain Software Engineering, addressing the issues posed by smart contract programming and other applications running on blockchains.We analyse a case of study where a bug discovered in a Smart Contract library, and perhaps "unsafe" programming, allowed an attack on Parity, a wallet application, causing the freezing of about 500K Ethers (about 150M USD, in November 2017). In this study we analyze the source code of Parity and the library, and discuss how recognised best practices could mitigate, if adopted and adapted, such detrimental software misbehavior. We also reflect on the specificity of Smart Contract software development, which makes some of the existing approaches insufficient, and call for the definition of a specific Blockchain Software Engineering.

A sociocultural analysis of organisational learning

Abstract: The concept of organisational learning has been widely debated and frequently contested by educationalists, but the specific processes and actions which constitute this form of learning have received relatively little research attention. This paper reports a three‐year empirical investigation into organisational learning in a large industrial complex, with the aim of clarifying the practices of organisational learning and interpreting them within sociocultural learning theory. A sociocultural model is proposed which identifies dialogue as the fundamental process by which organisations learn, and relational practices as the social structure which embeds the dialogue and makes it sustainable in a potentially conflictual environment. Three relational practices are analysed in detail: opening space for the creation of shared meaning, reconstituting power relationships and providing cultural tools to mediate learning. A pedagogy of organisational learning is defined in terms of participation in these practices...

Presenting Social Representations: A Conversation:

Abstract: Serge Moscovici's theoretical system of social representations is by now nearly 40 years old; yet, today, various social psychological activities surrounding this field seem to flourish more than ever; much research into social representations is being carried out all over Europe and on other continents; there is a European PhD programme on social representations and communication; there is an association and a network on social representations; and a journal on social representations is in the pipeline. At the same time the theory has its critics; some of them argue that the theory is too loose; others, that it is too cognitive; that it is not clear how the concept of social representation differs from other concepts, say, from attitudes, social cognition, beliefs, stereotypes, and so on; still others would like to marry the theory either to discourse analysis or to social constructivism(s) and constructionism-or to both of them at the same time. Readers of French, in addition, are familiar with Moscovic...
