The goal of intelligent transport systems (ITSs) is to enhance the network performance of vehicular ad hoc networks (VANETs). Even though it presents new opportunities to the Internet of Vehicles ...(IoV) environment, there are some security concerns including the need to establish trust among the connected peers. The fifth-generation (5G) communication system, which provides reliable and low-latency communication services, is seen as the technology to cater for the challenges in VANETs. The incorporation of software-defined networks (SDNs) also ensures an effective network management. However, there should be monitoring and reporting services provided in the IoV. Blockchain, which has decentralization, transparency, and immutability as some of its properties, is designed to ensure trust in networking platforms. In that regard, this article analyzes the combination of blockchain and SDN for the effective operation of the VANET systems in 5G and fog computing paradigms. With managerial responsibilities shared between the blockchain and the SDN, it helps to relieve the pressure off the controller due to the ubiquitous processing that occurs. A trust-based model that curbs malicious activities in the network is also presented. The simulation results substantially guarantee an efficient network performance, while also ensuring that there is trust among the entities.
Das Buch behandelt die Haftung der Intermediäre aus der Sicht des Internationalen Privat und Zivilverfahrensrechts. Im Mittelpunkt steht die Frage, welches Recht bei grenzüberschreitenden ...Sachverhalten, wie sie typischerweise im Internet entstehen, über die Haftung des Intermediärs, der eine Immaterialgüterrechtsverletzung durch Bereitstellen einer Plattform oder eines Zugangsdienstes ermöglicht, entscheidet. Ausgehend von den Vorgaben des immaterialgüterrechtlichen Territorialitätsprinzip und der darauf aufbauenden Schutzlandanknüpfung sowie deren Grenzen, den Vorgaben des Unionsrechts und der materiellrechtlichen Ausgestaltung verschiedener Formen der Haftung für die Ermöglichung von Immaterialgüterrechtsverletzungen im deutschen, französischen und US-amerikanischen Recht wird für die Haftung der Intermediäre eine eigenständige kollisionsrechtliche Anknüpfung befürwortet, die zur Anwendung eines vorhersehbaren Rechts führt.
Wychodząc poza paradygmat totalitarystyczny - przez pryzmat którego najczęściej jest przedstawiony okres komunizmu - autorka stawia sobie za cel „rozbrojenie jednolitej wizji stalinowskich reform i ...?zniewolonego uniwersytetu?" (s. 297). Dla syntetycznego ujęcia wyników badań autorki warto zacytować fragment zakończenia: O ile można uznać, że pierwsza hipoteza pracy została zweryfikowana pozytywnie i w okresie powojennym mamy do czynienia z projektem modernizacyjnym, zakładaj ącym zwiększenie dostępu do uczelni wyższych osobom z klas pracujących, to druga hipoteza o roli uniwersytetów podczas realizacji tego projektu została zweryfikowana negatywnie - uniwersytety jako instytucje, a w szczególności Uniwersytet Łódzki, nie stały się najważniejszymi miejscami zmiany społecznej. Jeśli taki pogląd autorki jest spójny z jej patrzeniem na PRL jako na projekt modernizacyjny, to z drugiej strony wydaje się - szczególnie biorąc pod uwagę mizerne rezultaty reform (o czym dalej) - że może ona przeszacowywać znaczenie zmian dyskursywnych, co z kolei postrzegać można jako rezultat uniwersalizacji inteligenckich sporów symbolicznych, pozostających (w dużym stopniu) w oderwaniu od „realnego" życia warstw mających być adresatami zmiany.

Recently studies examined mediating psychological constructs accounting for relations between both depression and anxiety with problematic smartphone use (PSU) severity. The aim of the current study ...was to analyze the fear of missing out (FOMO) as a possible mediator in these relationships.
We recruited 1034 Chinese undergraduate students via a web-based survey that measured smartphone use frequency, PSU, depression, anxiety and FOMO.
Structural equation modeling demonstrated that FOMO was significantly related to smartphone use frequency and PSU severity. FOMO significantly mediated relations between anxiety and both smartphone use frequency and PSU severity. FOMO did not account for relations between depression and smartphone use/PSU.
This is one of the first studies testing FOMO in relation to PSU severity among Asian participants. FOMO may be an important variable accounting for why some types of psychopathology (e.g., anxiety) are associated with PSU.
•Fear of missing out (FOMO) related to problematic smartphone use (PSU) severity.•FOMO mediated relations between anxiety and smartphone use frequency.•FOMO mediated relations between anxiety and PSU severity.
•A framework of challenges for implementing Industry 4.0 was proposed.•A novel multi-criteria decision making method named Best-Worst Method was used.•A practical application of the framework and the ...Best-Worst method occurred.•Managerial and practical implications of the study were presented.
Researchers and practitioners are giving significant attention to Industry 4.0 due to its numerous benefits to manufacturing organizations. Several aspects of Industry 4.0 have been studied in the literature. However, studies on the challenges for implementing Industry 4.0 in manufacturing operations have received less attention. To address this gap, this study identifies a set of challenges (framework) for implementing Industry 4.0 in manufacturing industries. This framework is evaluated in the leather industry of Bangladesh aided by a novel multi-criteria decision-making method named Best-Worst method (BWM). The findings of the study showed that ‘lack of technological infrastructure’ is the most pressing challenge that may hurdle the implementation of Industry 4.0 whereas ‘environmental side-effects’ is the less among the challenges that may hinder implementation of Industry 4.0 in the Bangladeshi leather industry. This result may help decision makers, industrial managers and practitioners in the Bangladeshi leather industry to realize the actual challenges confronting them when attempting to implement Industry 4.0 and focus their attention on how to address these challenges to pave ways for a successful implementation of Industry 4.0.
People are increasingly using the Internet to access health information and the information obtained has an impact on their healthcare outcomes. This paper examines the impacts of IT enablers and ...health motivators on peoples' online health information search behavior. We characterize users' online health information search behavior along three dimensions: the frequency of online health information search, the diversity of online health information usage, and the preference of the Internet for initial search. Using the 2003 Health Information National Trends Survey (HINTS) data on cancer, we find that ease of access to Internet services and trust in online health information could affect the three dimensional search behavior listed above. While perceived quality of communication with doctors has an impact on diversity of use and preference of use, we surprisingly do not find an impact on the frequency of search for online health information. In addition, our results find that perceived health status could affect both frequency and diversity of search for online health information. But we do not find evidence that perceived health status could lead to a preference for using the Internet as a source for health information.
► Ease of access to the Internet could affect the online health information search. ► Trust in online health information could affect people's search behaviors. ► Quality of communication with doctors has no impact on the frequency of search. ► Health status does not lead to a preference for using online health information.

The use of the Web in U.S. political campaigns has developed dramatically over the course of the last several election seasons. In Web Campaigning, Kirsten Foot and Steven Schneider examine the ...evolution of campaigns' Web practices, based on hundreds of campaign Web sites produced by a range of political actors during the U.S. elections of 2000, 2002, and 2004. Their developmental analyses of how and why campaign organizations create specific online structures illuminates the reciprocal relationship between these production practices and the structures of both the campaign organization and the electoral arena. This practice-based approach and the focus on campaigns as Web producers make the book a significant methodological and theoretical contribution to both science and technology studies and political communication scholarship.Foot and Schneider explore the inherent tension between the desire of campaigns to maintain control over messages and resources and the generally decentralizing dynamic of Web-based communication. They analyze specific strategies by which campaigns mitigate this, examining the ways that the production techniques, coproducing Web content, online-offline convergence, and linking to other Web sites mediate the practices of informing, involving, connecting, and mobilizing supporters. Their conclusions about the past decade's trajectory of Web campaigning point the way to a political theory of technology and a technologically grounded theory of electoral politics.A digital installation available on the web illustrates core concepts discussed in the text of the book with examples drawn from archived campaign Web sites. Users have the opportunity to search these concepts in the context of fully operational campaign sites, recreating the Web experience of users during the election periods covered in the book.
This book argues that Internet diffusion and use in the Middle East enables meaningful micro-changes in citizens' lives, even in states where no Arab Spring revolution occurred.
A Science "Reading List for Uncertain Times"
Selection "A must-read for anyone with even a passing
interest in the present and future of higher education." -Tressie
McMillan Cottom, author of Lower ...Ed "A must-read for the
education-invested as well as the education-interested."
- Forbes Proponents of massive online learning have
promised that technology will radically accelerate learning and
democratize education. Much-publicized experiments, often
underwritten by Silicon Valley entrepreneurs, have been launched at
elite universities and elementary schools in the poorest
neighborhoods. But a decade after the "year of the MOOC," the
promise of disruption seems premature. In Failure to
Disrupt , Justin Reich takes us on a tour of MOOCs,
autograders, "intelligent tutors," and other edtech platforms and
delivers a sobering report card. Institutions and investors favor
programs that scale up quickly at the expense of true innovation.
Learning technologies-even those that are free-do little to combat
the growing inequality in education. Technology is a phenomenal
tool in the right hands, but no killer app will shortcut the hard
road of institutional change. "I'm not sure if Reich is as famous
outside of learning science and online education circles as he is
inside. He should be…Reading and talking about Failure to
Disrupt should be a prerequisite for any big institutional
learning technology initiatives coming out of COVID-19."
- Inside Higher Ed "The desire to educate students well
using online tools and platforms is more pressing than ever. But as
Justin Reich illustrates…many recent technologies that were
expected to radically change schooling have instead been used in
ways that perpetuate existing systems and their attendant
inequalities." - Science
La democracia contemporánea se debate entre el vaivén de los modelos representativos y participativos. En ambos, la soberanía no ha encontrado total satisfacción. Por tanto, para superar dicho dilema ...es necesario evaluar los tipos de representación y los instrumentos de participación con el objetivo de alcanzar un tercer modelo: la Democracia Líquida. Aquí se exponen sus tres versiones: directa, mediada en los espacios ganados por partidos sin representantes partidarios y mediada por representantes proxies ad hoc. Se describe su capacidad de deliberación y la inclusión de Internet en la misma. Finalmente se elaboran algunas discusiones respecto a los límites de los argumentos expuestos y se concluye con las advertencias sobre sus alcances.
