The evolution of the technology 5G has influenced the Internet of the Things (IoT) according to the wireless communications of minor latency, and major speed compared to the existing technologies. Consequently, from the 21st century, 5G will act as the spinal column of the IoT and will level the way for the design and deployment of a Smart City, nevertheless, this progress has a negative point which is demonstrated in the energy consumption. The target of this investigation is to announce methods to reduce the consumption of energy in one Smart City based on the IoT and the technology 5G. The results obtained in this investigation allow determining that 5G and the IoT will have a major energy consumption with about 80 % of the entire potency, due to the transmission and reception of a big quantity of information in a Smart City. Likewise, this research, contributes to the knowledge, presenting a review of methods that allow minimizing energy consumption and projects that improve energy efficiency.

Abstract Green innovation undoubtedly plays a significant role in creating employment opportunities, boosting green economic activity, and improving environmental sustainability. This study scrutinizes the effect of energy efficiency and green innovation on CO2 emissions in China over the 1992–2014 period using NARDL. Findings show that energy efficiency and green innovation contribute to reducing CO2 emissions in China. Energy efficiency and green innovation are also important asymmetric determinants of CO2 emissions. An increase in energy efficiency and green innovation lowers CO2 emissions, while a decrease in energy efficiency and green innovation increases CO2 emissions in China in the long run. Some policy measures are suggested to attain carbon neutrality.

Recently, massive urbanization, increasingly denser cities and environmental consciousness are pushing architects to build “green” skyscraper. This paper examines the emergence of a notable type of skyscrapers which depart from purely image-driven structures, and emphasizes functionality and energy efficiency. It argues that breathtaking green design and practical clean technology are merged to give birth to green architectural aesthetics. Upon reviewing over 30 towers from various parts of the world, the paper identifies salient green design strategies that provide new iconicity including: structural efficiencies, renewable energy, façade technology, greeneries, and bioclimatic design. Findings suggest that a dynamic synergy among innovative green design strategies, new architectural languages and exciting aesthetics has constituted a trend that is more likely to prevail in the 21st Century.

This article attempts to lend an ear to the compact audio cassette: a key feature of the domestic soundscape from its introduction in the early 1960s until its gradual obsolescence in the first decades of the 21st century. The piece aims to provide a new perspective on the cassette by way of a discussion of the Start Here tapes project: a series of seven artist audio cassette tapes released in 2016 and 2017. Applying a practice-based methodology to a study of objects that are intimate and well known, the project seeks to foreground the material agency of the cassette by making work that reflexively references material objecthood. The article examines what is at stake politically in this focus on materiality, and considers the way creative forms of reflexivity might have renewed ethical and political value within a ecopolitical or biopolitical context.

The information age of the 21st century has transformed the economic, social, and political landscape in a profound and indelible manner. It also has changed the role and functions of government and redefined the scope and substance of good governance. Never before in human history has the pace of structural change been more pervasive, rapid, and global in its context. The information age has precipitated profound structural changes in the economic landscape and has given birth to the new economy. The new global economy is composed of a trilogy of interactive forces that include globalization, trade liberalization, and the information technology and communications revolution. Globalization has melted national borders, free trade has enhanced economic integration, and the information and communications revolution has made geography and time irrelevant (Passaris, 2001). Immigration has taken on a new perspective in the context of globalization. There is no denying that the spread of Internet-based technologies throughout society has become the dominant economic reality of the 21st century. E-economy—the use of information and communication technologies for product and process innovation across all sectors of the economy—has emerged as the primary engine of productivity and growth for the global economy. In large part due to advances in information and communications technologies, the role of international borders in this globalized economy has been transformed from the traditional geographical frontiers to virtual economic communities. Innovations in transportation and information and communications technology also has impacted immigration flows and made the world, in the phrase coined by Marshall McLuhan (1988), truly a “global village”. Borders have become less relevant for digital content communications and transactions. Cyberspace has no natural demarcations or border patrols. Indeed, knowledge-based products, such as software, games, and music, cross borders without impediment and with relative ease (Passaris, 2003). The advent of the information age has had a profound impact on the nature and scope of e-government and has given birth to the digital government of the 21st century. In particular, the interface between government and immigration management has been redesigned and restructured in terms of access to immigration information and application forms, the processing of immigration applicants for admission, enforcement of security measures and the prevention of terrorist infiltration, and the time line for adjudicating immigration applications, to name just a few of the significant changes to the contemporary process by which the governments of immigrant-receiving countries enforce their immigration policies.

The larger anthropic pressure on the Water Supply Systems (WSS) and the increasing concern for the sustainability of the large energy use for water supply, transportation, distribution, drainage and treatment are determining a new perspective in the management of water systems [...]
