Use Of The Internet

The Internet and electronic mail increasingly offer the research community opportunities that it did not previously have. Access to information has increased as has access to and discussion with those working in similar areas. One other aspect of ‘cyberspace’ which presents enormous possibilities to the research community, currently in its infancy, is the use of the Internet to reach individuals as research subjects. In particular, there may be significant research benefits to be gleaned where the group being researched is normally difficult to reach and/or the issues being researched are of a particularly sensitive nature. This paper outlines some recent survey research using the Internet as the interface between researcher and researched. The target group, illicit ‘drug dealers’, are difficult to access under normal conditions and contacting a spread of such individuals across international borders was previously prohibitive. A discussion of sampling issues is undertaken which concludes that the Internet can be a valuable source of indicative as opposed to easily generalizable data. A practical guide to undertaking research via the Internet is also included.

Use Of The Internet

Steganography, the process of hiding information, can be used to embed information or messages in digital files. Some uses are legitimate, such as digital watermarking or the combination of text with medical images. But the technique can also be used for criminal purposes or by terrorists to disguise communications between individuals. We discuss some commonly available steganographic tools, the detection of stegonography through steganalysis, and future challenges in this domain. In the future, the legality of steganography may depend on legal issues and challenges. Jurisdictional differences may play a role. Privacy will have to be balanced by the duty of authorities to safeguard public safety, both from threats by criminals and terrorists. Techniques for steganalysis will become increasingly important, and will be complicated by the use of the Internet and emerging technologies such as VOIP. Packet routing complicates analysis of files, and new data streams offer new opportunities for hiding information. An internationally coordinated response to threats may be necessary.

The growing number of threats and challenges from cyberspace, due to the increasing use of the Internet and mobile applications as never before, requires the implementation of security policies aimed at preserving the information and communication assets of the company. Security is achieved through one part of measures that are technical-technological in nature, and the other part is related to the actions of people in the organization. People are known to be the weakest link, and security culture aims to act on people by adopting certain behaviours, building habits and establishing communication in a way that they can respond to threats from cyberspace. Information security culture is established and maintained through programs that aim to prepare people for current and future challenges from cyberspace. One day, young people will start working, but until that moment, parents, in synergy with school institutions, should direct them so that they accept certain behaviours and norms. In this way, the security culture ensures that their security is preserved from the earliest days, so it is necessary to develop programs at different levels of education that will enable this.

The Internet Of Things

Over the years, technological advancements have led to rapid growth of smart environments (offices, homes, cities, etc.). The increase of intelligent environments suggests the interconnectivity of applications and the use of the Internet. For this reason, arise what is known as the Internet of Things (IoT). The expansion of the IoT concept gives access to the Internet of Nano Things (IoNT). A new communication networks paradigm based on nanotechnology and IoT, in other words, a paradigm with the capacity to interconnect nano-scale devices through existing networks. This new paradigm so-called IoNT is presented to the world as an option for various fields of application. Therefore, new challenges and research opportunities have arisen. Consequently, this work aims to investigate state of the art and analyze trends for the use of IoNT, its application and future challenges in different fields of social interest, because IoNT is presented as an option for research with the capacities needed to get involved in many fields of social welfare.  It is concluded that technologies prevail current IoNT literature, applications are focused on health care, and there is no international standardization regarding privacy, security or architecture of nano-networks.

Youth Vote

This paper examines a few of the numerous factors that may have led to increased youth turnout in 2008 Election. First, theories of voter behavior and turnout are related to courting the youth vote. Several variables that are perceived to affect youth turnout such as party polarization, perceived candidate difference, voter registration, effective campaigning and mobilization, and use of the Internet, are examined. Over the past 40 years, presidential elections have failed to engage the majority of young citizens (ages 18-29) to the point that they became inclined to participate. This trend began to reverse starting in 2000 Election and the youth turnout reached its peak in 2008. While both short and long-term factors played a significant role in recent elections, high turnout among youth voters in 2008 can be largely attributed to the Obama candidacy and campaign, which mobilized young citizens in unprecedented ways.

Jerusalem played an important role in the establishment of collective memory studies by Maurice Halbwachs in the early twentieth century. Recent studies in this field draw attention to the contribution of a variety of agents to building, maintaining, and challenging collective memory realms. Following suit, this article deals with the methods that agents of an alternative collective memory for Jerusalem use to challenge the Israeli hegemonic narrative. Before reviewing their activities in East and West Jerusalem and their resources and impact, I summarize the hegemonic narrative as presented in four memory realms. Special attention is given to both sides’ use of the Internet as a means of overcoming the physical limitations of memory realms.

Main Activity

This article is devoted to the study of the multimedia environment of the polemic discourse in German media with its diverse formats of impact on the audience and the actively developing internal dynamics of texts. If at the end of the XXth century the specifics of German media were the use of the Internet site as one of the possibilities to present copies of newspapers and magazines in electronic form, today we can speak of modified, hybrid Internet versions of printed publications that do not just create websites on the Internet that duplicate their main activity, but also combines the features of the traditional press and features of the functioning of texts on the Internet. The transition from linear, monomedia broadcasting platforms to discrete, multimedia ones has a significant impact on the process of creating, designing and placing modern polemics. Texts of articles and user comments are considered in the article as tmaterialization of the polemic discourse in the media. Polemic texts are formed on the basis of intertextual structures and have a hypertext nature. The use of multimedia tools (a variety of fonts, graphics, animation, photo, video and sound) in the text of the article allows the author not only to expand the amount of information provided, but also to qualitatively supplement its content through inline inclusions tn the text, to express the meaning of information by referring to verbal and non-verbal means; to provide a visual and figurative presentation of information (graphs, charts, tables), to attract attention and influence the audience, as well as to provide readers with the opportunity to participate in information exchange.

Abstrak: Bagi generasi pasca milenial penggunaan internet sangat akrab tetapi dengan berbagai tujuan penggunaan. Penelitian ini ingin melihat keterkaitan penggunaan internet oleh penduduk yang sedang sekolah untuk kepentingan penyelesaian tugas sekolah di Indonesia untuk mendapatkan hasil belajar yang baik. Analisis berdasarkan data sekunder dari Survei Sosial Ekonomi Nasional tahun 2018. Hanya saja data yang didapatkan tidak simetris dengan adanya pencilan. Regresi kuantil digunakan untuk meminimumkan pengaruh dari pencilan yang ada. Penelitian mendapatkan hasil bahwa terdapat kaitan yang erat antara akses internet dari penduduk yang sedang sekolah dengan penyelesaian tugas sekolah.  Hasil regresi kuantil menunjukkan bahwa proporsi akses internet untuk penyelesaian tugas sekolah berbeda antar golongan proporsi penggunaan internet. Proporsi penggunaan internet yang tinggi akan digunakan untuk penyelesaian tugas sekolah yang lebih tinggi pula. Abstract: For the post millennial generation the use of the internet is very familiar but with various purposes of use. This study wants to look at the relationship between the use of the internet by residents who are currently in school for the sake of completing school work in Indonesia to get good learning outcomes. Analysis based on secondary data from the 2018 National Socio-Economic Survey. It's just that the data obtained is not symmetrical with outliers. Quantile regression is used to minimize the effect of outliers. The study found that there was a close relationship between internet access from residents who were in school and completion of school work. The quantile regression results show that the proportion of internet access for completing school work differs between groups of proportions of internet use. A high proportion of internet use will be used for completing higher school work.
