This paper investigates the effect of exchange-traded funds’ (ETFs’) activity on the short-run informational efficiency of their underlying securities. We find that ETF activity increases short-run informational efficiency for stocks with weak information environments. The increase in informational efficiency results from the timely incorporation of systematic earnings information. In contrast, we find no such effect for stocks with stronger information environments. ETF activity increases return comovement, and this increase is partly attributable to the timely incorporation of systematic ear...

Using the panel data of 66 countries for the period 1996–2019, the current research explores the influences of information and communication technology (ICT) on energy security. We consider the role of financial development, human capital and technological development to explore the channels through which ICT influences energy security. Our empirical results reveal the adverse impact of ICT on energy demand and energy security. In addition, ICT mainly affects energy security through financial development and technological progress. Although human capital can significantly affect energy securit...

Room temperature phosphorescence materials have garnered significant attention due to their unique optical properties and promising applications. However, it remains a great challenge to finely manipulate phosphorescent properties to achieve desirable phosphorescent performance on demand. Here, we show a feasible strategy to finely manipulate organic phosphorescent performance by introducing dynamic lanthanide coordination. The organic phosphors of terpyridine phenylboronic acids possessing excellent coordination ability are covalently embedded into a polyvinyl alcohol matrix, leading to ultra...

A review of the academic literature on the ISO/IEC 27001, the most renowned standard for information security and the third most widespread ISO certification is presented, providing solid foundations for future research on the topic.

There is a nexus of seven inter-linked global existential challenges; Soil Security and Food Security are two of these. The established concept of Food Security is well defined and researched, whereas the emerging concept of Soil Security is building its currency globally. Addressing Soil Security provides the means to improve food, fibre and water quality in a sustainable manner, through enhanced soil care and development of best land-management practices. Soil is a fragile resource which is degraded in many parts of the world. The rapidly growing global population has placed further pressure...

Climate change is increasingly recognised as a security issue. Yet this recognition belies contestation over what security means and whose security is viewed as threatened. Different accounts – here defined as discourses – of security range from those focused on national sovereignty to those emphasising the vulnerability of human populations. This book examines the ethical assumptions and implications of these 'climate security' discourses, ultimately making a case for moving beyond the protection of human institutions and collectives. Drawing on insights from political ecology, feminism and c...

Starting with the historical evolution of computer and communications networks and their security, the book then arrives at the main definitions of cryptography and network security. Next, the basics of information theory, how to measure information, the information associated with a certain source are also discussed. Source codes are presented, along with the concepts of information transmission, joint information, conditional entropy, mutual information and channel capacity. Computer networks are discussed, including the main protocols and network architectures, and the important TCP/IP prot...

Abstract The optical anti‐counterfeiting science and technology are currently restricted by the limited information loading capacity, and thus development of multi‐level and high‐security systems is urgently needed but still challenging. Herein, anti‐counterfeiting design strategies (including ASCII/5D codes and dynamic information storage) are reported by incorporation of abundant multi‐central luminescence and time‐resolved, excitation‐dependent ultralong phosphorescence. Self‐assembly of new single‐component 0D organic–inorganic metal halides (OIMHs) are facilely achieved, which exhibit div...

MPC has moved from theoretical study to real-world usage. How is it doing?

This article starts from the premise that International Political Economy (IPE) literature – with some notable exceptions – has a blind spot for the colonial and contested histories of financial infrastructures. Often considered to be the mere ‘plumbing’ of international finance, financial infrastructures instead are profoundly political and rooted in long-term colonial histories. To start addressing these blind spots, the article draws on literatures in critical infrastructure studies, that offer understandings of infrastructure as lively, contested and profoundly political. The argument is t...

This paper reviews this physical notion of security, focusing on quantum key distribution and secure communication, which relies entirely on the laws of quantum mechanics.

This chapter discusses the chief objectives of securing a network and provides information on information security terminology. The aim of network security is to provide proactive defense methods and mechanisms to protect a network against internal and external threats. The three main objectives in securing a network are to ensure: confidentiality, integrity, and availability. The chapter describes the types of network security and the chief risks related to the logical security of a network. Different kinds of network attacks include reconnaissance attack, password attacks access attacks, net...

Approximately 30 years after the birth of IoT, society is confronted with significant challenges regarding IoT security. Due to the interconnectivity and ubiquitous use of IoT devices, cyberattack...
