The Media

The availability of versatile multimedia processing software and the far-reaching coverage of the interconnected networks have facilitated flawless copying and manipulations of digital media. The ever-advancing storage and retrieval technologies also have smoothed the way for large-scale multimedia database applications. However, abuses of these facilities and technologies pose pressing threats to multimedia security management in general, and multimedia copyright protection and content integrity verification in particular. Although cryptography has a long history of application to information and multimedia security, the undesirable characteristic of providing no protection to the media once decrypted has limited the feasibility of its widespread use. For example, an adversary can obtain the decryption key by purchasing a legal copy of the media but then redistributing the decrypted copies of the original.

Although anthropologists have long addressed topics related to media and communications technologies, some have argued that a truly institutionalized commitment to the anthropology of media has only developed within the past twenty years. This might be due, at least in part, to a traditional disciplinary emphasis on “primitive” communities lacking the ostensible features of modernity, including electronic forms of mass mediation. Thick description, a central aim of ethnography as touted by Clifford Geertz, was historically geared toward small-scale societies and precluded the study of contemporary forms of mass media in modern life. However, anthropologists have begun to develop productive ways of including mass mediation into their ethnographic accounts. Indeed, it is becoming increasingly difficult to talk about cultural practices at all without some nod to the ubiquity of global media. From an anthropological perspective, it is important to consider varying cultural contexts of mass-media production, consumption, and interpretation. And this begs a question that several anthropologists have begun to answer. What is the most appropriate way to study “the media” as a cultural phenomenon? Content analyses of media texts? The measuring and identifying of media’s social effects and influence? Ethnographic studies of “reception” and “production”? Or something else entirely? Anthropologists engage in all of these and more. Additionally, new questions are emerging about how anthropology might best address digital media and online communities. There are multiple ways in which anthropologists have engaged with “the media” both as a tool of representation and an object of study. To outline some of those ways, it makes sense to provide a history of developments in the field, summarizing several thematic topics that have recently been of central focus to anthropologists of media, including religion, globalization, and nationalism. It also makes sense to think about approaches to studying mass media that other disciplines deploy—disciplines that are in conversation with anthropologists on this subject, including and especially media studies, communications studies, and cultural studies. The categorical divisions here attempt to reflect anthropology’s historical commitments to various analytical, thematic, and medium-based modes of inquiry.

With the development of network, an increasing amount of broadcast television information transforms from simulation into digit, which therefor make the security of media information an imminent issue to be concerned. In this paper, a new kind of intrusion detection model was designed for the media information security system. In the system, both the false alarm rate and missing report rate decreased by using support vector machine classification technique in this new model. As a result of the experimental results, our algorithm processed a high classification accuracy and efficiency.

Large Scale Survey

The vast amount of information available online makes the origin of information, its quality, and its veracity less clear than ever before, shifting the burden on individual users to assess information credibility. Contemporary youth are a particularly important group to consider with regard to credibility issues because of the tension between their technical and social immersion with digital media, and their relatively limited development and life experience compared to adults (Metzger & Flanagin, 2008). Although children may be highly skilled in their use of digital media, they may be inhibited in terms of their ability to discern quality online information due to their level of cognitive and emotional development, personal experience, or familiarity with the media apparatus compared to adults. This chapter presents the findings of a large-scale survey of children in the U.S. ages 11-18 years examining young people’s beliefs about the credibility of information available online, and the strategies they use to evaluate it. Findings from the study inform theoretical, practical, and policy considerations in relation to children’s digital literacy skills concerning credibility evaluation.

Modern mass media, as an important means of informing the public, determines people’s consciousness, shapes their interests and determines the mood. It has also successfully incorporated the role of an educator from the very beginning. Thus, the media linguistics plays a special role in spreading the native Georgian language, as well as in raising the literacy rate of the population. Language is the main tool to guide human cognitive activity. Although, there are many examples of media trying to comply with linguistic norms, modern broadcasting fails to maintain proper Georgian; digital media being particularly full of many linguistic and stylistic errors. It should also be noted that electronic media is the only source of information for many, especially the young people. Given the high social importance, journalists should be careful with dealing with the language. The development and transformation process of mass media in the global information space is not only indirectly but also directly reflected, especially in the formation of the Internet media linguistics. The current social and political changes in the country have also affected the process of language deformation. The scientific article deals with the influence of media language on the linguistic features of the Georgian society. It discusses the problematic issues of modern publicist thinking, focusing on the linguistic distortions that modern journalists are characterized with. The speech problem of media representatives is topical, complex and large-scale. Their speeches are the basis of the communicative interaction of the society, contribute to the linguistic influence, national identity, mutual understanding of people, perception of the world. The media significantly influences the value system, mentality and literary norms used in any society. Violation of literary norms, which is observed in modern Georgian media, has a negative impact on the audience and the level of literary competence of the speakers.

Cuba has long been saddled with a culture of corruption. A lengthy history of colonialism and a state-controlled economy have produced a country with a weak economy, product shortages, low wages, and an understanding that taking a little for oneself is not only acceptable but, in many cases, necessary to get by. Scarcity and rationing of resources have led to an environment where obtaining goods and services requires grease payments, workers steal items from their employers to sell on the black market, and employees are often absent so that they can earn extra money from side jobs. At the same time, poorly paid bureaucrats, business managers, and even high-level government officials supplement their income through illicit use of their positions. The centralization of power, strict government control of the media, and lax compliance oversight have led to a lack of transparency and accountability. While high-level corruption on a large scale is less common in Cuba than other parts of Latin America, lower-level corruption is widespread. Over the years, the ruling Castro regime has taken a number of approaches to curbing corruption that have led to laws and institutions aimed at eliminating corrupt conduct, fraud, waste, abuse, and cronyism. However, there is little protection for whistle-blowers in Cuba. Accordingly, a vital tool in the effort to detect and prevent bribery, the misuse of government funds, fraud, and other types of corruption is largely missing.

The post-Soviet space has seen a large-scale transformation of media markets that is marked with an unprecedented rise of entrepreneurial initiatives across business sectors, including media businesses. This paper analysed the dynamics of Russian media markets and the challenges of Russian media entrepreneurs. The media markets of Russia shifted toward more concentration and fragmentation, and media holdings are continuously gaining more power. This paper also looked at the regional media markets of Russia. According to research, there are less than 20 self-sustainable regional media holdings in Russia due to the low capacity of regional advertising markets. National media holdings have a diversified portfolio consisting of different types of media with a growing fraction of digital media companies, and the regional media lag behind in terms of its digital component. Most regional media holdings operate traditional media. Their digital channels are yet to be developed, despite the chief executives' acknowledgement that the future of revenue streams comes from digital channels.

In the history of warfare various media and technologies have been devised both to enable contingent events in the form of scenarios and simulations and to reign them in and bring the proliferation of possible futures under control. War games, horoscopes, astrolabes, celestial and topographical maps have in different ways served as ‘contingency media’, i.e. tools that enable strategic thought and action under conditions of uncertainty. Through the prism of Schiller's Wallenstein from 1799, this essay examines the development of military contingency media from the 17th to the early 19th century. Delving into the disagreements between Johannes Kepler and the historical Wallenstein about the reach and power of astrological star charts and horoscopes, the essay analyzes Schiller's late Enlightenment critique of astrological contingency media as well as his transformation of them into productive poetic devices. Finally, it situates the play in the context of military theory around 1800 in which contingency emerged as a central factor of large-scale warfare. A historically complex document, Wallenstein serves as an archive of the shifting conceptions of war and of the media devised to manage its uncertain futures.
