    Managing by Walking Around

    {Excerpt} Management by walking around emphasizes the importance of interpersonal contact, open appreciation, and recognition. It is one of the most important ways to build civility and performance in the workplace. The hallmarks of the modern organization are satellite offices, remote offices, home offices, virtual offices, hotelling facilities, and the electronic mail that underpins—and promotes—these. Today, knowledge workers receive few telephone calls and electronic mail is their communication vehicle of choice. (The use of videoconferencing is growing,too.) After all, why should they walk around if they can type, point, and click? At the receiving end, managers are known to collect more than 150 messages each day. Yet, as knowledge workers on the rise tote up electronic status, they also distance themselves from colleagues. Managing by walking around was popularized by Tom Peters and Robert Waterman in the early 1980s because it was (already then) felt that managers were becoming isolated from their subordinates. At Hewlett-Packard, where the approach was practiced from 1973, executives were encouraged to know their people, understand their work, and make themselves more visible and accessible. Bill Hewlett and Dave Packard\u27s business philosophy, centered on deep respect for people and acknowledgment of their built-in desire to do a good job, had evolved into informal, decentralized management and relaxed, collegial communication styles. Theirs was the opposite of drive-by management

    Implementation and testing of a Neighborhood Office Center (NOC) and integration of the NOC with an administrative correspondence management information system

    The application of telecommunications and telecomputing was investigated as a means of reducing NASA's consumption of natural resources and the proliferation of paper copies of correspondence. The feasibility, operational advantages, and limitations of decentralized (remote) neighborhood offices (NOC) linked through an electronic network are demonstrated. These offices are joined to a management information system for correspondence tracking, and to an administrative office center service based on the use of magnetic medium word processing typewriters which handle the daily typing load. In connection with an augmented teleconference network, a uniform means is provided for creating, storing, and retrieving administrative documents, records, and data, while simultaneously permitting users of the system to track their status. Information will be transferred without using paper - merely through digital electronic communication and display, as a step toward the establishment of an agency-wide electronic mail system

    ClaimChain: Improving the Security and Privacy of In-band Key Distribution for Messaging

    The social demand for email end-to-end encryption is barely supported by mainstream service providers. Autocrypt is a new community-driven open specification for e-mail encryption that attempts to respond to this demand. In Autocrypt the encryption keys are attached directly to messages, and thus the encryption can be implemented by email clients without any collaboration of the providers. The decentralized nature of this in-band key distribution, however, makes it prone to man-in-the-middle attacks and can leak the social graph of users. To address this problem we introduce ClaimChain, a cryptographic construction for privacy-preserving authentication of public keys. Users store claims about their identities and keys, as well as their beliefs about others, in ClaimChains. These chains form authenticated decentralized repositories that enable users to prove the authenticity of both their keys and the keys of their contacts. ClaimChains are encrypted, and therefore protect the stored information, such as keys and contact identities, from prying eyes. At the same time, ClaimChain implements mechanisms to provide strong non-equivocation properties, discouraging malicious actors from distributing conflicting or inauthentic claims. We implemented ClaimChain and we show that it offers reasonable performance, low overhead, and authenticity guarantees.Comment: Appears in 2018 Workshop on Privacy in the Electronic Society (WPES'18

    Systematizing Decentralization and Privacy: Lessons from 15 Years of Research and Deployments

    Decentralized systems are a subset of distributed systems where multiple authorities control different components and no authority is fully trusted by all. This implies that any component in a decentralized system is potentially adversarial. We revise fifteen years of research on decentralization and privacy, and provide an overview of key systems, as well as key insights for designers of future systems. We show that decentralized designs can enhance privacy, integrity, and availability but also require careful trade-offs in terms of system complexity, properties provided, and degree of decentralization. These trade-offs need to be understood and navigated by designers. We argue that a combination of insights from cryptography, distributed systems, and mechanism design, aligned with the development of adequate incentives, are necessary to build scalable and successful privacy-preserving decentralized systems

    The Role of International Rules in Blockchain-Based Cross-Border Commercial Disputes

    [excerpt] The concept of online dispute resolution (ODR) is not new. 1 But, with the advent of Web 3.0, the distributed web that facilitates pseudonymous and cross-border transactions via blockchain\u27s distributed ledger technology, 2 the idea of, and pressing need for, appropriate dispute resolution models for blockchain-based disputes to support this novel system of distributed consensus and trust of which blockchain proponents boast, is a primary concern in rapid development. 3 The common goal of each project is to utilize smart contracts to facilitate superior, quicker[,] and less expensive proceedings by eliminating so many of the tedious and protracted trappings of traditional arbitral proceedings, such as the sending and receiving of documents via courier. , Despite myriad approaches, all emerging blockchain-based dispute resolution services (BDR solutions) generally seek to bridge the divide between automated performance mechanisms, like smart contracts, and the human judgment traditionally required to settle legal disputes.5 How our existing legal frameworks must develop to ensure that smart contracts 6 facilitate, rather than frustrate, the parties\u27 intent is a critically important question to ask as the blockchain stack\u27s infrastructure and application layers are being built and, ultimately, scaled. Indeed, interest is high in the race to create alternative dispute resolution mechanisms to resolve disputes arising from blockchain-based commercial transactions that, due to the transnational, borderless, pseudonymous, and distributed nature of blockchain, clearly necessitate international solutions.

    Blockchain-based Decentralized Distribution Management in E-Journals

    The application of blockchain in the context of E-Journal distribution to journalists is aimed at making the management paper adequately distributed and not misused. The security system in the distribution or management paper process of an open journal system is currently considered to be very lacking because one can duplicate the journal in an open journal system easily. Furthermore, it can be transferred to anyone who is not responsible. The security system in the distribution of an open journal system and the management of the management paper process is currently considered to be very lacking because one can duplicate the journal in an open journal system easily. Furthermore, it can be transferred to anyone who is not responsible. With the implementation of this blockchain technology, there are 3 (three) benefits, namely (1) The distribution of E-Journal in the Open Journal System is more targeted, and there are no errors. (2) The reputation of the Open Journal System becomes better with a sense of trust. This research will be implemented in an E-Journal in an Open Journal System using blockchain technology. (3) The management paper processing in the open journal system runs according to the procedure so that in the management process the distribution of soft copies and hard copies of the journal is protected from hacker threats, and this blockchain is used to guarantee its security
