This article takes stock of the smart city concept by locating it in relation to both a longer history of urban computing, as well as more recent projects exploring the vexed issues of participatory urbanism, data ethics and urban surveillance. The author argues for the need to decouple thinking regarding the potential of urban digital infrastructure from the narrow and often technocentric discourse of ‘smart cityism'. Such a decoupling will require continued experimentation with both practical models and conceptual frameworks, but will offer the best opportunity for the ongoing digitization of cities to deliver on claims of ‘empowering' urban inhabitants.

Vehicular Edge Computing (VEC), based on the Edge Computing motivation and fundamentals, is a promising technology supporting Intelligent Transport Systems services, smart city applications, and urban computing. VEC can provide and manage computational resources closer to vehicles and end-users, providing access to services at lower latency and meeting the minimum execution requirements for each service type. This survey describes VEC’s concepts and technologies; we also present an overview of existing VEC architectures, discussing them and exemplifying them through layered designs. Besides, we describe the underlying vehicular communication in supporting resource allocation mechanisms. With the intent to overview the risks, breaches, and measures in VEC, we review related security approaches and methods. Finally, we conclude this survey work with an overview and study of VEC’s main challenges. Unlike other surveys in which they are focused on content caching and data offloading, this work proposes a taxonomy based on the architectures in which VEC serves as the central element. VEC supports such architectures in capturing and disseminating data and resources to offer services aimed at a smart city through their aggregation and the allocation in a secure manner.

In this special issue of Nova Religio four historians of medieval and early modern Christianities offer perspectives on basic conceptual frameworks widely employed in new religions studies, including modernization and secularization, radicalism/violent radicalization, and diversity/diversification. Together with a response essay by J. Gordon Melton, these articles suggest strong possibilities for renewed and ongoing conversation between scholars of “old” and “new” religions. Unlike some early discussions, ours is not aimed simply at questioning the distinction between old and new religions itself. Rather, we think such conversation between scholarly fields holds the prospect of productive scholarly surprise and perspectival shifts, especially via the disciplinary practice of historiographical criticism.

The businesses generate an “intranet” to hang about connected to the internet but secured from possible threats. Data integrity is quite a issue in security and  to preserve that integrity we tends to develop as to provides the better encryption processes for security. In this work  we will make a  encryption harder with enhanced public key encryption protocol for the  security and we will talk about the applications for proposed work. We will enhance the hardness in security by humanizing the Diffie-Hellman encryption algorithm by making changes or adding some more security codes in up to date algorithm. Network security has become more important to not public computer users, organizations,  and the military.With the start of the internet, security became a major disquiet and the history of security allows a better understanding of the emergence of security technology. The  internet structure itself allowed for many security threats  to  occur.When the architecture of the internet is modified it can decrease the possible attacks that can be sent across the network. Knowing the attack methods, allows  for  the suitable security to  appear. By means of the firewalls and encryption   mechanisms  many businesses protected themselves from the internet.The firms crank out an “internet" to hold around connected into this world wide web but procured from potential dangers. Data ethics is a significant dilemma in protection and also to conserve integrity we all are inclined to grow concerning furnishes exactly the encryption procedures such as the security. Inside this job we'll earn a encryption tougher using improved general security protocol to your own stability and we're going to discuss the software for projected work. We'll improve the hardness of stability by humanizing that the Diffie Hellman encryption algorithm by generating alterations or including a few far more stability codes up to date algorithm. Network safety has gotten more very important to perhaps not people users, associations, and also the army. With all the beginning of internet, stability turned into a significant vexation along with the foundation of safety makes it possible for a superior comprehension of the development of technology. Even the online arrangement itself enabled for most security dangers that occurs. After the structure of this world wide web is altered it could diminish the probable strikes which may be transmitted from the other side of the community. Recognizing the assault procedures, permits the acceptable stability to arise. With this firewalls and security mechanics many companies shielded themselves out of the world wide web.

Abstract This article argues that the neglect of narratives about the end of religious traditions is due to a complex entanglement of our positions as historical narrators and specifics of the sources for histories of religions, that is of emic and academic narrators. Typically, academic histories are not only based on emic narratives, but also tend to accept their conceptual frameworks with regard to the unities of description. It will be shown that such an entanglement has consequences for the neglect of the end of religious practices or groups. Against this background an analytical grid for change and discontinuation of different dimensions of “religion” will be offered and exemplified in an analysis of the “end of Paganism” in the late ancient Roman Empire. The most problematic implications of such narratives, the article will argue, are assumptions about the coherence of the religious protagonists brought center-stage.

Nation and empire are intriguing conceptual frameworks for the study of the historical persistence of Atlantic entanglements—especially in the northern hemisphere. The Atlantic might generally be understood to have interlocked the Americas, Africa, and Europe from the beginning of European westward exploration until the official end of both slavery and European imperialism on Northern American soil. But Atlantic ideological battles extended well beyond the 19th century. Today, they are alive and kicking once more. As conceptual frameworks nation and empire organize ideas of belonging, community building, and social cohesion. In addition, they are short-hands for distinct, in fact competing, forms of political and economic hegemony. Since mechanisms of exclusion and seclusion have forged, delimited, and expanded nations as much as empires, this bibliographical essay will focus on studies that draw attention to the commonalities of nation and empire. Within the framework of the (Northern) Atlantic, nations and empires lose their cohesive and exclusivist aura, inviting persistent, if contrastive, comparisons of connective as well as divisive modes of transportation, exchange, and intellectual as well as cultural transformation. The idea of nation evokes several meanings: First used in Anglo-Norman and Middle French to denote birth, lineage, or family, the idea of the nation helped to lay the ground for modern-age ideas of race and biological descent. As a social and cultural concept, the nation organizes communities around questions of kinship, belonging, and culture until today. From the 19th century onward “nation” simultaneously described a political formation established by and for its diverse population. Empire likewise has many layers: etymologically speaking the word is used to speak about extensive territories controlled by a single ruler; politically speaking the term describes a system governed by ideas of supreme sovereignty and extensive subjection or domination; socially speaking it relates practices of command and control. Culturally speaking, empire denotes complex communication among communities with various degrees of authority and power. Scholarly analysis often delineates historical trajectories. From a Eurocentric perspective the New World attracted competing communities of settlers, planters, and traders, rewarding both an unbridled sense of possibility and the ambition to emulate and yet outdo European models. In this ambiguous setting the idea as well as institutional offsprings of empire proliferated long after empire officially ended with the First World War. With the return of empire (and nation) as imaginaries for new forms of coercion and collaboration, future scholarship will need to trace the Atlantic and its history of entanglements well into the 21st century.

Background: The history of reading, writing, and the dissemination of technology is one of epochal change, and each transition – indeed the history of the book – is marked by hybridity. In the mature years of print, publishers, librarians, and scholars had clearly defined and segregated roles. In the digital realm, the boundaries have broken down. Just now we have hybridity of form and of roles in the implementation of new reading environments.Analysis: This article provides: 1) an overview of e-reading environments; 2) a survey of the Dynamic Table of Contexts interface; and 3) a report on the hybrid production process of a particular online text, Regenerations.Conclusion and implications: Regenerations could only have emerged from a collaboration among a digital infrastructure project, research project, university press, and digital humanities tool suite.

Problematic use of data, patterns of bias emerging in AI systems, and the role of platforms like Facebook and Twitter during elections have thrown the issue of data ethics into sharp relief. Yet the focus of conversations about data ethics has centered on computer scientists, engineers, and designers, with far less attention paid to the digital practices of artists and others in the cultural sector. Artists have historically deployed new technologies in unexpected and often prescient ways, making them a community able to speak directly to the changing and nuanced ethical questions faced by those who use data and machine learning systems. We conducted interviews with thirty-three artists working with digital data, with a focus on how artists prefigure and commonly challenge data practices and ethical concerns of computer scientists, researchers, and the wider population. We found artists were frequently working to produce a sense of defamiliarization and critical distance from contemporary digital technologies in their audiences. The ethics of using large-scale data and AI systems for these artists were generally developed in ongoing conversations with other practitioners in their communities and in relation to a longer history of art practice.

In 2016, between Guangdong strikes in mainland China and Hong Kong’s unionization momentum, Hong Kong artist Wong Ka Ying posted a call on Facebook founding the Hong Kong Artist Union (HKAU). The gesture followed the mischievously named Come Inside, Hong Kong’s ‘first female artist duo’ created by Wong and artist Mak Ying Tung, which declared it would combat art’s ‘formalized system’. Ironically, one of its first actions was to enrol in a course on insurance that could help it formalize healthcare for artists. Come Inside welcomed the idea that opposition to the ‘system’ brings artists into it. HKAU took shape within this ‘trap’ when Wong and Mak started researching trade unions. ‘On Union, Displaced’ explores the past four years of HKAU existing as a union-not-yet-registered-as-an-official-union, a serious gesture of ludic conceptualism that plays with artistic freedom’s relationship to captivity and capture. Through Rey Chow’s theory of conceptual art as trap, it traces HKAU’s entanglement in the history of Hong Kong art groups, regional labour organizing, and efforts to reground the term ‘artist’. Studying HKAU requires various conceptual frameworks: Yuk Hui’s cosmotechnics; Laikwan Pang’s multiple sovereignties; Sandro Mezzandra and Brett Neilson’s border-as-method; Linda Lai Chiu-han’s performative research; and Frank Vigneron’s plastician. The article explores how being ‘plastic’ – a union displaced; a union whose registration with the Hong Kong Special Administrative Region is perpetually negotiated – has helped HKAU pose important questions about solidarity and sovereignty in art.
