Abstract Educators are constantly looking for new ways to inspire students to actively engage with science. Learning how to navigate by using the stars, sun and moon can be one of the first steps for pupils, students and the general public to cultivate an interest in astronomy. With this in mind, an online platform based on the Google Earth and Stellarium software has been developed. It presents basic celestial navigation techniques that were first devised and deployed by the ancient Phoenicians and Greeks, the Vikings and the Polynesian travellers. Both software applications are free to use and are available in web versions, making them easily accessible to anyone with an internet connection. The user undertakes a set of predefined tasks that take him/her on a fascinating journey both around the world and back in time.

The software engineering field has been a fountain of innovation. Ideas and inventions from the software domain have literally changed the world as we know it. For software development, we have a few proven innovations. The way software is built remains surprisingly primitive. Even in 2008 major software applications are cancelled, overrun their budgets and schedules, and often have hazardously bad quality levels when released. There have been many attempts to improve software development, but progress has resembled a drunkard’s walk. Some attempts have been beneficial, but others have been either ineffective or harmful. This article puts forth the hypothesis that the main reason for the shortage of positive innovation in software development methods is due to a lack of understanding of the underlying problems of the software development domain. A corollary hypothesis is that lack of understanding of the problems is due to inadequate measurement of quality, productivity, costs, and the factors that affect project outcomes.

LIFI was first introduce by Professor Harald Haas on July 2011. Light fidelity (LI-FI) may be a technology which uses light as a medium to travel from one place to a different. It uses Light like Light Emitting Diode (LED) visible radiation Communication (VLC) for data Transferring and Internet connection. LIFI may be a technique which uses light as a medium because it uses light to travel it's 20 times faster than any WIFI within the world. during this paper we speak about things like what's LIFI and the way it's better then WIFI why we want LIFI and What changes did bring LIFI in our Future LIFI. How it'll make IOT devices far better than before The Technique to implement LIFI and also the problem we face of implementation of LIFI

Finland represents an educational utopia for many educators and decision-makers around the world. The Nordic country is known for its excellence in learning results and the emphasis it lays on equality/equity in education. This paper focuses on the way the latter has been presented and constructed in two popular commercial products on Finnish education: a book and a 60-minute documentary. Audiences for both include educational scholars and practitioners, decision-makers and the general public. The authors examine assumptions, ideologies, and silences in the discussions of equality and equity behind the discourse of excellence in Finnish education. As Finland is actively involved in marketing its education around the world, this calls for a review of the myths and realities of Finnish education.

Broadband commonly refers to Internet connection speeds greater than narrowband connection speed of 56kbs. Digital subscriber lines (DSL) and cable modems were the most popular forms of broadband in public use over the last 10 years. In 2004, over 80% of U.S. homes were equipped with cable modems, and up to 66% of U.S. households were able to receive DSL transmissions. It is expected that the impact of broadband technologies will continue to play an important role in the U.S. and the rest of the world. It is predicted that the number of broadband-enabled homes will exceed 90 million worldwide by 2007 (Jones, 2003). Canada and Korea currently are the two countries leading the way in broadband saturation. The following discussion focuses on the Canadian case of broadband development.

The term “Web services” was initially employed by Bill Gates, chairman of Microsoft, at the Microsoft Professional Developers Conference in Orlando, Florida on July 12, 2000. Fundamentally, the term refers to automated resources accessed via an Internet URL. However, a more comprehensive definition is that of the World Wide Web Consortium (W3C)1, which declare Web services as “providing a standard means of interoperating between different software applications, running on a variety of platforms and/or frameworks.” An Internet connection allows retrieval of software-powered resources or functional components and is therefore regarded as an extension of the World Wide Web infrastructure. Web services represent the evolution of a human-oriented utilization of the Web to a technology that is application driven. It attempts to replace human-centric searches for information with searches that are primarily application based (Staab, 2003).

Весной 2020 года, когда мир охватила пандемия новой коронавирусной инфекции, многие дети из семей мигрантов, как и другие школьники, столкнулись с необходимостью перехода на дистанционное обучение. Для многих маленьких мигрантов переход на освоение знаний в режиме онлайн оказался невозможным из-за отсутствия гаджетов и компьютеров, нестабильного интернета или его полного отсутствия. Но, кроме чисто технических проблем, возникли и другие препятствия на пути к получению этой категорией детей качественного образования. Среди них – невозможность получения дополнительных консультаций, сокращение сферы коммуникации на новом для них языке и социальная изоляция. В статье анализируется влияние, которое оказало распространение коронавирусной инфекции, на сферу обучения и интеграции детей из семей международных мигрантов. During the spring 2020, when the world was captured by the new coronavirus contagion, many children from migrants’ families along with other students, faced the need of transition to a distance learning. For many little migrants the process of gaining knowledge online appeared to be unreal because they do not have any gadgets or computers, their internet connection is unstable or absent. But, besides clear technical problems, there arose other obstacles on the way to good quality education for this category of children. The obstacles involve the impossibility to get supplementary language consultations, a cutback of the sphere of communication with the use of a language that is new for such children, a social isolation. The author of the article analyzes an influence that the spread of coronavirus infection has made on the sphere of education and integration of children from the families of international migrants.

Abstract. This research took place just after the end of the protests following the killing of a 16-year-old boy by a policeman in Greece in December 2008. Participants (N = 224) were 16-year-olds in different schools in Attiki. Informed by the Politicized Collective Identity Model ( Simon & Klandermans, 2001 ), a questionnaire measuring grievances, adversarial attributions, emotions, vulnerability, identifications with students and activists, and questions about justice and Greek society in the future, as well as about youngsters’ participation in different actions, was completed. Four profiles of the participants emerged from a cluster analysis using representations of the conflict, emotions, and identifications with activists and students. These profiles differed on beliefs about the future of Greece, participants’ economic vulnerability, and forms of participation. Importantly, the clusters corresponded to students from schools of different socioeconomic areas. The results indicate that the way young people interpret the events and the context, their levels of identification, and the way they represent society are important factors of their political socialization that impacts on their forms of participation. Political socialization seems to be related to youngsters’ position in society which probably constitutes an important anchoring point of their interpretation of the world.

This article considers how pre-existing music has been employed in British cinema, paying particular attention to the diegetic/nondiegetic boundary and notions of restraint. It explores the significance of the distinction between diegetic music, which exists in the world of the narrative, and nondiegetic music, which does not. It analyses the use of pre-existing operatic music in two British films of the same era and genre: Kind Hearts and Coronets (1949) and The Importance of Being Earnest (1952), and demonstrates how seemingly subtle variations in the way music is used in these films produce markedly different effects. Specifically, it investigates the meaning of the music in its original context and finds that only when this bears a narrative relevance to the film does it cross from the diegetic to the nondiegetic plane. This reveals that whereas music restricted to the diegetic plane may express the outward projection of the characters' emotions, music also heard on the nondiegetic track may reveal a deeper truth about their feelings. In this way, the meaning of the music varies depending upon how it is used. While these two films may differ in whether or not their pre-existing music occupies a nondiegetic or diegetic position in relation to the narrative, both are characteristic of this era of British film-making in using music in an understated manner which expresses a sense of emotional restraint and which marks the films with a particularly British inflection.
