Vehicular Edge Computing: Architecture, Resource Management, Security, and Challenges

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.

Sissy Insurgencies

In Sissy Insurgencies Marlon B. Ross focuses on the figure of the sissy in order to rethink how Americans have imagined, articulated, and negotiated manhood and boyhood from the 1880s to the present. Rather than collapsing sissiness into homosexuality, Ross shows how sissiness constitutes a historically fluid range of gender practices that are expressed as a physical manifestation, discursive epithet, social identity, and political phenomenon. He reconsiders several black leaders, intellectuals, musicians, and athletes within the context of sissiness, from Booker T. Washington, George Washington Carver, and James Baldwin to Little Richard, Amiri Baraka, and Wilt Chamberlain. Whether examining Washington’s practice of cleaning as an iteration of sissiness, Baldwin’s self-fashioned sissy deportment, or sissiphobia in professional sports and black nationalism, Ross demonstrates that sissiness can be embraced and exploited to conform to American gender norms or disrupt racialized patriarchy. In this way, sissiness constitutes a central element in modern understandings of race and gender.

Engaging Students Through Integrated Pedagogy

This case study presents a model of integrated pedagogy in a two-semester college-level General Chemistry course. The model was designed to engage students safely during the first year of the COVID-19 pandemic. The authors use the term “Integrated Pedagogy” to emphasize that several modes of active learning pedagogy. The technology incorporated into the course was not as an add-on enhancement but as an essential and central element. The laboratory component was integrated into the course as an independent, self-directed experience. Informal student surveys suggest that the model may transform the traditional approaches to chemistry education to meet the changing needs of diverse student populations.

Digital Technology Deployment in the German Automotive Industry

Mobility is a central element of the new networked world, and customers expect highly integrated features in their vehicles and want to be able to use services or features at any time in a highly integrated manner. As a result, the entire automotive industry is facing a major change process, both technological as well as in its own core business processes and functions. This chapter examines the impact of this transition on the conduct and sustainability of IT projects in the German automotive industry. Information distilled from in-depth interviews with industry practitioners reveals how project management methods, tools, and culture have to evolve, as value chains in the industry are re-evaluated and re-defined. The chapter puts forward a framework for the interaction of project management methods and digital technologies to achieve sustainable project processes and outcomes. It is hoped this may act as a building block for future research in this field to advance the transitioning of the industry and its inherent IT projects to a more sustainable future.

Smart concept in rural tourism: a comparison between two phases (2016-2019)

Smart Tourism is the main component of current destinations, however, there are severe difficulties for its application in small destinations. This problem is essential in the case of rural tourism. Taramundi is one of the most important rural destinations in Spain. There are two surveys about tourists conducted in 2016 and 2019. These surveys are about obtaining data on changes in the behavior of tourists in the dynamic field of mobile technologies. The results indicated the importance of the smartphone for rural tourism, the temporary growth in the use of its tourist utilities, and most importantly, the technological applications that improve the enjoyment stay. The rural tourist does not abandon the use of pre- and post-travel regarding Information and Communication Technologies (ICTs), but the interest in Tics during travel increases significantly. Specifically, the App of Destiny is the central element of smart rural tourism, seeing that it should focus on the increase of new technographic utilities for tourists. In the perspective of Gretzel (2018), the application of the concept of Smart Tourist Destination is impossible in rural areas. However, with a specialization approach, rural destinations must work towards the goal of “smartification.”

Methods of digital marketing positioning in the global civil passenger aircraft market

Under conditions of intense competition, the creation of new products and their promotion to the market requires marketing support. The central element of marketing innovation management is marketing positioning. In contrast to the methodological aspect, there is almost no procedural component of positioning in scientific works and publications. Moreover, due attention is not paid to the issues of market segmentation and the allocation of the competitive advantage of such high-tech products as civil aircraft. This determines the relevance of the task of developing a procedure for marketing positioning within the framework of managing the product offer of the aircraft industry enterprises. From the standpoint of a systematic approach, the necessity of studying the adjacent air transportation market is reasonable, as well as the analysis of the correlation of its segmentation with the allocation of target segments of the aircraft market. When conducting a competitive analysis, we propose to consider the market position not only of certain types of civil aircraft, but also of aircraft families. Modeling marketing management shows the role of positioning in the processes of creating, manufacturing and operating aircraft. A distinctive feature of the procedure is the proposed stage of evaluating the effectiveness of the selected product position implementation, which allows us to analyze the feasibility of marketing decisions throughout the product life cycle. Special attention is paid to the issues of information support. The research results presented here reflect the specifics of the marketing activities of aviation industry enterprises and contribute to the development of the conceptual foundations of industrial marketing.

Information Operations Increase Civilian Security Cooperation

Information operations are considered a central element of modern warfare and counterinsurgency, yet there remains little systematic evidence of their effectiveness. Using a geographic quasi-experiment conducted during Operation Enduring Freedom in Afghanistan, we demonstrate that civilians exposed to the government’s information campaign resulted in more civilian security cooperation, which in turn increased bomb neutralisations. These results are robust to a number of alternative model specifications that account for troop presence, patrol-based operations, and local military aid allocation. The paper demonstrates that information campaigns can lead to substantive attitudinal and behavioural changes in an adversarial environment and substantially improve battlefield outcomes.

Multilingual humour in audiovisual translation

This commentary aims to take up the gauntlet thrown down by Dore (2019) with her article about multilingual humour in the Italian dubbed version of the series Modern Family. She suggested that the scenes included in the article could be analysed in other languages, so it was an interesting proposal to carry out the analysis of the Spanish dubbed version, since the L2 in the source text coincides with the target text language. Thus, this fact makes the translation process an arduous activity in these language combinations. Multilingualism is therefore considered the central element in this study. It is a reflection of the current social movement and the increase of multi-ethnic communities worldwide. This fact leads to citizens who use their knowledge to assert their own identity; as a consequence, audiovisual producers are also aware of this situation and exploit this phenomenon. Modern Family is an example of this reality and introduces characters, like Gloria Delgado-Pritchett, as a role model to show an increasingly common tendency, the use of multilingual and multi-ethnic characters that reflect this new social situation. Thanks to the selected examples, we will see whether the use of multilingualism as a source of humour is also transmitted to the Spanish dubbed version, as it did in the Italian dubbed version studied by the abovementioned scholar.

The Zip4 protein directly couples meiotic crossover formation to synaptonemal complex assembly

Meiotic recombination is triggered by programmed double-strand breaks (DSBs), a subset of these being repaired as crossovers, promoted by eight evolutionarily conserved proteins, named ZMM. Crossover formation is functionally linked to synaptonemal complex (SC) assembly between homologous chromosomes, but the underlying mechanism is unknown. Here we show that Ecm11, a SC central element protein, localizes on both DSB sites and sites that attach chromatin loops to the chromosome axis, which are the starting points of SC formation, in a way that strictly requires the ZMM protein Zip4. Furthermore, Zip4 directly interacts with Ecm11, and point mutants that specifically abolish this interaction lose Ecm11 binding to chromosomes and exhibit defective SC assembly. This can be partially rescued by artificially tethering interaction-defective Ecm11 to Zip4. Mechanistically, this direct connection ensuring SC assembly from CO sites could be a way for the meiotic cell to shut down further DSB formation once enough recombination sites have been selected for crossovers, thereby preventing excess crossovers. Finally, the mammalian ortholog of Zip4, TEX11, also interacts with the SC central element TEX12, suggesting a general mechanism.

Liturgy in Lockdown: Restricted Movement, Expanded Worship

What has the pandemic taught us about worship? Reflecting on religion in quarantine, Heidi A. Campbell observed that while many churches have embraced a new medium of worship (digital), the underlying approach to worship has remained centered on the worship event. Campbell criticizes this event-based focus as being out of step with the networked age in which we live. Is Campbell right, or is there still a place for the worship event, even in this networked age? Drawing on the work of liturgical theologians and network theorists, I revisit the role of the liturgical event in the wider life of the church, arguing that the liturgical event remains a central element of the church’s mission, but that the liturgy is meant to take worshippers beyond itself. I suggest that pandemic reflections on liturgy should lead the church to emphasize that Christians are a sent people, even during a time of restricted movement. This shift in emphasis from gathering to sending out redefines the church more broadly and helps us reclaim a more expansive vision of worship beyond the mere event.
