Information Disorder : Algorithms and Society
This book focuses on the recent rise of “infodemics” as forms of disinformation, misinformation and mal-information saturate contemporary media platforms, shaping public opinion to advance agendas. The internet in general and social media in particular have relativized, through their global, complex and instantaneous information flows, assumptions about truth and authority in fact-based content.This has created new opportunities for state actors to use information beyond traditional conceptions of propaganda to directly assault a public’s conception of reality.Additionally, almost anyone has the capability to challenge evidential claims through narratives and imagery alone as there is a wide appetite online for alternative realities.This requires new approaches to media literacy in education, the creative arts and our acts of media consumption and dissemination.The volume covers the ways that social media platforms amplify and catalyze the messages of politicians and influencers, the ambivalence of algorithms that can both generate and detect problematic information, how fake news imitates the style of memes to gain widespread social traction and virality, and how artists have intentionally created “sicko AIs” in new media performances to highlight the ethical risks of increasingly “intelligent” technologies. Scholars and students from many backgrounds, as well as policy makers, journalists and the general reading public, will find a multidisciplinary approach to questions posed by information disorder research from the fields of communication, social psychology, human-computer interaction, journalism, media, semiotics and new media art.

Algorithms : Technology, Culture, Politics
Algorithms: Technology, Culture, Politics develops a relational, situated approach to algorithms.It takes a middle ground between theories that give the algorithm a singular and stable meaning in using it as a central analytic category for contemporary society and theories that dissolve the term into the details of empirical studies. The book discusses algorithms in relation to hardware and material conditions, code, data, and subjects such as users, programmers, but also “data doubles”.The individual chapters bridge critical discussions on bias, exclusion, or responsibility with the necessary detail on the contemporary state of information technology.The examples include state-of-the-art applications of machine learning, such as self-driving cars, and large language models such as GPT. The book will be of interest for everyone engaging critically with algorithms, particularly in the social sciences, media studies, STS, political theory, or philosophy.With its broad scope it can serve as a high-level introduction that picks up and builds on more than two decades of critical research on algorithms.

Hybrid Encryption Algorithms over Wireless Communication Channels
This book presents novel hybrid encryption algorithms that possess many different characteristics.In particular, “Hybrid Encryption Algorithms over Wireless Communication Channels”, examines encrypted image and video data for the purpose of secure wireless communications.A study of two different families of encryption schemes are introduced: namely, permutation-based and diffusion-based schemes.The objective of the book is to help the reader selecting the best suited scheme for the transmission of encrypted images and videos over wireless communications channels, with the aid of encryption and decryption quality metrics.This is achieved by applying number-theory based encryption algorithms, such as chaotic theory with different modes of operations, the Advanced Encryption Standard (AES), and the RC6 in a pre-processing step in order to achieve the required permutation and diffusion.The Rubik’s cube is used afterwards in order to maximize the number of permutations. Transmission of images and videos is vital in today’s communications systems.Hence, an effective encryption and modulation schemes are a must.The author adopts Orthogonal Frequency Division Multiplexing (OFDM), as the multicarrier transmission choice for wideband communications.For completeness, the author addresses the sensitivity of the encrypted data to the wireless channel impairments, and the effect of channel equalization on the received images and videos quality. Complete simulation experiments with MATLAB® codes are included.The book will help the reader obtain the required understanding for selecting the suitable encryption method that best fulfills the application requirements.

Digital Totalitarianism : Algorithms and Society
Digital Totalitarianism: Algorithms and Society focuses on important challenges to democratic values posed by our computational regimes: policing the freedom of inquiry, risks to the personal autonomy of thought, NeoLiberal management of human creativity, and the collapse of critical thinking with the social media fueled rise of conspiranoia. Digital networks allow for a granularity and pervasiveness of surveillance by government and corporate entities.This creates power asymmetries where each citizen’s daily ‘data exhaust’ can be used for manipulative and controlling ends by powerful institutional actors.This volume explores key erosions in our fundamental human values associated with free societies by covering government surveillance of library-based activities, cognitive enhancement debates, the increasing business orientation of art schools, and the proliferation of conspiracy theories in network media. Scholars and students from many backgrounds, as well as policy makers, journalists and the general reading public will find a multidisciplinary approach to questions of totalitarian tendencies encompassing research from Communication, Rhetoric, Library Sciences, Art and New Media.

How do logarithmic sorting algorithms work?
Logarithmic sorting algorithms work by dividing the input data into smaller subgroups and recursively sorting these subgroups. One common example is the merge sort algorithm, which divides the input list into two halves, sorts each half separately, and then merges them back together in sorted order. By repeatedly dividing the data and merging the sorted subgroups, logarithmic sorting algorithms achieve a time complexity of O(n log n), making them efficient for large datasets.
