The new sources of light (laser and led) that have been invented and developed during the last fifty-sixty years have given origin to a true scientific and technological revolution. This article synthetically follows the main steps of the history of light, which started by studying the properties of solar emission, and introducing the concept of electromagnetic wave. At the end of the 19th century there was experimental evidence that it was necessary to complicate the approach by introducing the assumption that the electromagnetic energy is a discrete, and not continuous, quantity. The new concept led to design and realization of the laser and the led. Through the utilization of these sources fundamental progress was achieved in both science and technology, by deepening the description of wave-particle dualism and of the coherence concept, by putting on a completely new basis information and communication technology, and by giving new tools to industrial and biomedical sensing.

This paper presents some sociological debates involved in the new field of life sciences at the end of 20th century. From a bibliographic review concerning history of science and Social Studies of Science, it will be presented some particular sociological issues of the research on molecular biology and its historical evolution – the formation of speeches and legitimization; institutional arrangements and alliances in post-war period. We will focuses on the emerging systems of information and communication technology, ICTs. and how it transformed the biomedical research. The goal is to show briefly how molecular biology was built, from the post-war period to the end of the 90’s, and what was the main proceedings of interdisciplinary associations and technoscientific interactions in the life sciences agenda.

This essay examines the history of electoral modernization in the Philippines from its beginning in the early 1990s to the present. The essay identifies the problems the country has encountered and accomplishments it has achieved and draws lessons from these experiences which may be useful for electoral modernization in other countries with similar socioeconomic conditions. It will become clear that not only the characteristics of the technologies but also political, legal, administrative, economic, and even socio-cultural factors have significant influence, both positive and negative, on the modernization process.

The Australian Antarctic Division has a long history of providing telecommunications as part of the support provided to expeditioners within the Australian Antarctic Territory. Since the days when Mawson’s expedition in 1911 setup the first transmitter at Commonwealth Bay, the Division has provided continuous and increasingly sophisticated telecommunications capability that now includes data to support medical services, science, education and Internet access. The provision of telecommunications to Antarctica relies on satellite transmission for backhaul.

<p><em>Education is a important thing in a human civilization history. The progress of a civilization is mostly determined by education as a main factor. Throughout the history of human civilization, there were so many learning methods has been invented such as discussion method, discourse method, group teaching, and technology-supported learning method. The fast development of Information and Communication Technology (ICT) in the era of information society has facilitated all of knowledge seekersnowdays to learn something better and better.E-Learning as a implementation of ICT in education domain takes the role as a education media which provide education content so that the students are able to access it times infinity.</em></p>

Transportation is an essential part of human activity that allows people to move from one place to other places. Modern transportation systems refer to intelligent transportation systems (ITS). It has been proven that information and communication technology (ICT) has a significant role to improve the quality and security transportation services. ITS can be described as an integration of computer, electronics, and communication technologies and management strategies that can increase the efficiency and safety of transportation. The application is a platform that manages the vehicles, drivers, passengers, road operators, and managers in an environment that is suitable for everyone to communicate and interact. This chapter presents the history of transportation systems and the role of ICT to bring ITS in different transportation modes. The main motivation of the chapter is to survey the various technology-enabled ITS systems that have been in place, analyzing their strengths and providing recommendations for such ITS systems in developing countries to improve the governance.

For the last two decades, corpus technologies, understood as a combination of means and methods of processing and analyzing data of electronic linguistic corpora, as a type of information and communication technology, have attracted great interest of researchers and teachers of foreign languages.We explain the concepts of corpus linguistics, corpus technology, linguistic corpus, concordance. The methods of studying case technologies, which are an annotation, abstraction, and analysis, are considered. The advantages of linguistic corpora are given. The history of the emergence and development of linguistic electronic cases from the pre-digital to digital period is described. Minimum requirements for the corpus of texts are presented. They include representativeness, known volume of the corpus, electronic form, annotation and balance. We consider the typology of linguistic corpora. According to the language of the texts in corpora, there are monolingual and multilingual corpora, which in turn are divided into mixed and parallel ones. According to language data, there are written, oral and mixed corpora. Corpora can be annotated and non-annotated. There are three types of annotation: linguistic, metatextual, and extralinguistic. According to the parameter of representation of the language material of a corpus, there are fragmented and non-fragmented ones. According to the type of access, they are classified as open and restricted. According to the genre representation, linguistic corpora are diverse. The size of a corpus should distinguish between representative, illustrative and monitoring types of corpora. The didactic properties of corpus technologies in the field of teaching a foreign language are studied. The division of the linguodidactic properties of case technologies into mandatory and optional is proposed.

This paper studies whether and how information and communication technology (ICT) changes self-construal and cultural values in a developing country. Ethiopian children were given laptops in the context of an ICT for development scheme. We compared children who used laptops (n = 69) with a control group without laptops (n = 76) and a second control group of children whose laptop had broken down (n = 24). Results confirmed that after 1 year of laptop usage, the children’s self-concept had become more independent and children endorsed individualist values more strongly. Interestingly, the impact of laptop usage on cultural values was mediated by self-construal (moderated mediation). Importantly, modernization did not “crowd out” traditional culture: ICT usage was not associated with a reduction in traditional expressions (interdependent self-construal, collectivist values). Theoretical and practical implications are discussed.
