There is no doubt that the semiconductor contributed very significantly to changing our world in the long run, which made it very necessary to write this article and shed light on the semiconductor between past and  present. Whereas, this article is not intended to teach you semiconductor chemistry and its applications, but it also aims to refresh your memory with everything related to semiconductors from the moment of sunrise to the present day.As known, people need to communicate with each other in order to meet their daily and professional needs. In the past, the communication process was very difficult and sometimes costly until the emergence of what is known as semiconductors, which in turn opened new purview in the world of communications through its entry into the communication devices industry and computers industry and its ability to processing The data, in turn, facilitated and summarized a very long journey on humans in the field of industry. Today, we are on the beginning of a new sun rise of semiconductor, especially after the emergence of the so-called nanotechnology, where semiconductors have been observed a very large role in the development of this technology, not only but have become Part of the integral ones.

Over the past two decades, immigration receiving states have resorted to extraordinary legal, political, spatial tactics to curtail and prevent different types of migrants from legally entering the states. Some of these processes increased the number of undocumented and unauthorized immigrants in certain countries. These processes also lead to enormous personal sacrifices and hardships for families across the world. My personal experiences are probably not the worst case due to my educational and professional background, although there were few bumps in the road. Some of the following notes, I hope, will shed light on the personal experiences dealing with immigration law and processes.

La normativa de la Unión Europea en el campo de la protección de datos es la más exigente del planeta. En cambio hay países con una regulación poco exigente, o incluso sin regulación de ningún tipo. Estas diferencias pueden conducir a que la protección conseguida en el seno de la Unión se pierda en el momento en que los datos puedan ser localizados en naciones con un nivel inferior o completamente nulo de protección. Para evitarlo se han regulado minuciosamente las transferencias internacionales de datos. En este trabajo se pretende dar luz a algunos de los aspectos menos conocidos de los movimientos internacionales de datos personales. Analizamos un documento fundamental del Grupo de Trabajo del artículo 29 de la Directiva 95/46/CE: el WP 12. Revisamos la competencia de la AEPD en cuanto a la evaluación de los Estados que proporcionan un nivel adecuado de protección. Examinamos la necesidad de cumplir con las disposiciones legales en el caso de transferencia internacional. Por último reflexionamos sobre los cambios previstos en la propuesta de Reglamento comunitario de protección de datos.The European Union legislation in the field of data protection is the most demanding in the world. But there are countries with lax regulation, or no regulation of any kind. These differences may lead to the protection achieved within the Union lost in the moment that the data may be located in countries with a lower level of protection or completely invalid. To avoid this we have carefully regulated international data transfers. This paper aims to shed light on some of the lesser known aspects of international flows of personal data. We analyzed a fundamental document of the Working Group of Article 29 of Directive 95/46/EC: the WP 12. We review the jurisdiction of the AEPD regarding the evaluation of states that provide an adequate level of protection. We examined the need to comply with the laws in the case of international transfer. Finally we reflect on the changes envisaged in the proposed EU regulation on data protection.

By definition, archival science is a set of knowledge about archival material and archival activity. Archival scienceis a young science because it has been developing for the past hundred years. More recently, theory, practice and methodology have been formed. When we talk about archival material, we need to know that it’s not just a pile of old paper preserved in the dark archive storage rooms. Archival material is a record in continuity - from the moment it is created, until the moment someone searches for that record. Today it is a common belive that archives are the memory of society and a part of cultural heritage. Today, documents are mostly generated in electronic form. From a practical point of view, modern archival science deals with answers to contemporary issues such as: How to organize digitalisation of archival material? How to keep digital content in the long run? How to organize digital archives? How to care for data security? These are just some questions that will have to be answered by the generations that come - young archivists. To be able to protect contemporary archives for the future we will have to find abwers to above questions, than only by protecting the present we will be able to preserve it for the future.

This paper claims that, since many of the concepts relevant to our analysis of systemic change were coined in and about the core, the potential with which solutions to world-systemic crisis are credited in the long run should be assessed differently depending on the structural location of their origin. In the periphery, such concepts as conservatism, socialism and even liberalism took forms that often retained nothing of the original model but the name, such that strategies of applying them to (semi)peripheral situations ranged from “stretching the ideology” to “discarding the (liberal) myth” altogether. In a first step, “the hypothesis of semiperipheral development” (Chase-Dunn and Hall), according to which the semiperiphery represents the most likely locus of political, economical, and institutional change, is amended to say that, at least for the late modern world-system, the strength of the semiperiphery resides primarily in the cultural and epistemic sphere. In a second step, this contention is illustrated with the help of major challenges that the Eastern European and Latin American (semi)peripheries have posed to the world-system’s political fields and institutional settings both in the past and to date—with different degrees of success corresponding to their respective structural position. In light of these examples, it is argued that a comparative analysis of continuities among political epistemologies developed in the semiperiphery can help us understand the ways in which similar attempts can become antisystemic today.

Since the 1970's, global efforts have been going on to replace the high-enriched (>90% 235U), low-density UAlx research reactor fuel with high-density, low enriched (<20% 235U) replacements. This search is driven by the attempt to reduce the civil use of high-enriched material because of proliferation risks and terrorist threats. American initiatives, such as the Global Threat Reduction Initiative (GTRI) and the Reduced Enrichment for Research and Test Reactors (RERTR) program have triggered the development of reliable low-enriched fuel types for these reactors, which can replace the high enriched ones without loss of performance. Most success has presently been obtained with U3Si2 dispersion fuel, which is currently used in many research reactors in the world. However, efforts to search for a replacement with even higher density, which will also allow the conversion of some high flux research reactors that currently cannot change to U3Si2 (eg. BR2 in Belgium), have continued and are for the moment mainly directed towards the U(Mo) alloy fuel (7-10 w% Mo). This paper provides an overview of the past efforts and presents the current status of the U(Mo) development.

Baroness Susan Greenfield’s origins are humbler than her title might suggest. Her father was a machine operator in an industrial neighbour-hood of London. In Britain, unlike many other countries, it is possible to earn a peerage through your own merits rather than pure heredity. Lady Greenfield is a leading world authority on the human brain. She is concerned that technology has invaded our lives so profoundly that it has begun to affect the way our brains operate and hence our very personalities. “People are longing for experiences rather than searching for meaning,” she says. “They live more in the moment and have less of a sense of the narrative of their lives—of continuity. They lack a sense of having a beginning, a middle, and an end. They have less of a feeling that they are developing an identity throughout their life with a continuing story line from childhood, youth, parenthood, to grandparenthood. The emphasis is more on process than content. You now have people who are much more ‘sensitive’ rather than ‘cognitive.’ ” Susan Greenfield identifies one of the causes of this development as the impressions our brains receive from a very early age. Modern life, she argues, with its hectic rhythm of visual impressions is very different from the past, in which she includes her own childhood in the 1950s and 1960s. It’s in our youth that our brains are shaped: They grow like mad during the first 2 years of life, developing a maze of connections. And in the years that follow, they remain extremely nimble, forming new connections rapidly and changing in response to our surroundings. It is very much the world around us during infancy, childhood, and early adolescence that determines the outcome of this stage of brain formation. The brain displays an immense degree of what Greenfield likes to call “plasticity” during this stage; connections are formed as and when they are needed. The foundations of Baroness Greenfield’s own personality were laid in a similar way during her youth.

There exists an enormous interest in clarification of the relationship between education and economic growth. Over the past 30 years, there have been conducted studies by economists about the connection between education and economic growth. There are actually many publications which provide strong evidence that suggests a correlation between the two. This paper attempts to build upon previous publications and to introduce a unique insight along with contemporary evidence about the relationship between education and economic growth in India from 1975 to 2016 by foc using on primary, secondary and tertiary levels of education. The relationships are examined by utilization of econometric estimations with the Granger Causality Method and the Cointegration Method. These methods are used to create models that could shed light on the claim that education plays a central and significant role in economic growth of India which could consequently be used as an example for similar countries in Asia or around the world. The findings of this work show that there is compelling evidence proving a positive connection between education levels and economic growth in India which might influence governmental actions and shape the future of India.

During the last twenty years, the Russian adverb davno ‘long ago, for a long time’ was widely discussed in literature. It was recognized that the unique parameter of davno is its inability to be the theme of a sentence. Moreover, if davno functions in the context of aspectual forms relating to the past it can only be the rheme. In the context of the aspectual verbal forms relating to the past but preserving the connection with the moment of speech, davno can be either the rheme proper, or a component of the rheme. A classic example of an aspectual verb form referring to the past is the general factual meaning of the imperfective aspect. At present, the spoken data corpora can shed light on the communicative structure analysis, since the prosodic structure of the sound speech provides a straightforward access to the communicative structure. Novel parameters of davno are as follows. 1) Whereas davno is traditionally recognized as a word of rhematic polarity it can nevertheless function as a component of the theme in the context of attributive clauses and constructions (Davno soglasovannyj visit dolzhen byl sostojatjsja v aprele ‘A visit planned long ago would take place in April’). 2) The general factual meaning of the imperfective aspect, contrary to what was assumed before, is not an absolute prerequisite for davno to function as the rheme. The spoken corpus showed that in the context of negation and in the context of the verbs of speech, the general factual allows for davno to function as a component of the rheme but not the rheme proper (Ja davno tebja ne videl ‘I have not been seeing you for a long time’; My davno govorili, chto nasha zadacha — eto borjba s terrorismom ‘We have been insisting for a long time that our main goal is the struggle against terrorism’). 3) A specific type of questions with the initial davno (as well as with other adverbs with the meaning of a considerable quantity like chasto ‘often’, mnogo ‘much’, and daleko ‘far away’) is singled out. Such questions cannot be unambiguously classified either as yes-no-questions or as wh-questions (I davno vy zdesj stoite? ‘And how long are you staying here?’). A description of unique prosody of such questions is given. 4) In the context of discourse continuity, davno acquires the rising prosody which is in fact uncharacteristic of a word, which is unable be the theme (Xotel eto sdelat’ davno, no teperj sdelaju tochno ‘I wished to do it long ago, but now I will do it for sure’). The rising tone is accounted for by the meaning of continuity, which has the same prosody as the theme. 5) In constructions kogda-to davno ‘once upon a time’, ochenj davno ‘very long ago’, davno-davno ‘very long ago’, davnymdavno ‘very long ago’, dovoljno davno ‘quite long ago’, ne tak davno ‘not so long ago’ davno loses its rhematic polarity. The parameters of davno are exemplified by spoken fragments taken from the Multimodal corpus of the Russian National corpus, and the minor working collection of the Russian speech recordings specifically set up for this investigation. The software program Praat was used in the process of analyzing the sound data.

The moment of birth was once the instant where parents and others first saw their child in the world, but with the advent of various imaging technologies, most notably the ultrasound, the first photos often precede birth (Lupton, 2013). In the past several decades, the question is no longer just when the first images are produced, but who should see them, via which, if any, communication platforms? Should sonograms (the ultrasound photos) be used to announce the impending arrival of a new person in the world? Moreover, while that question is ostensibly quite benign, it does usher in an era where parents and loved ones are, for the first years of life, the ones deciding what, if any, social media presence young people have before they’re in a position to start contributing to those decisions. This chapter addresses this comparatively new online terrain, postulating the provocative term intimate surveillance, which deliberately turns surveillance on its head, begging the question whether sharing affectionately, and with the best of intentions, can or should be understood as a form of surveillance. Firstly, this chapter will examine the idea of co-creating online identities, touching on some of the standard ways of thinking about identity online, and then starting to look at how these approaches do and do not explicitly address the creation of identity for others, especially parents creating online identities for their kids. I will then review some ideas about surveillance and counter-surveillance with a view to situating these creative parental acts in terms of the kids and others being created. Finally, this chapter will explore several examples of parental monitoring, capturing and sharing of data and media about their children, using various mobile apps, contextualising these activities not with a moral finger-waving, but by surfacing specific questions and literacies which parents may need to develop in order to use these tools mindfully, and ensure decisions made about their children’s’ online presences are purposeful decisions.

The words of modern narrators help bring to surface the contradictions and conflicts typical of the metropolis, transforming it into a sort of cultural instrument that reads the different languages, images and forms of life that it is defined by. The crisis of perception of space and time, the difficulty of using a language that is able to give meaning, the shattering of personal identity, all make it hard to accumulate experiences and transform them into stories to pass on. The only way to start a relationship with the other and with the world is, as Charles Baudelaire and Walter Benjamin state, the moment of choc, the moment lived and that cannot be transmitted. The urgency is to not become a prisoner of the nostalgia for the past, but to make the irreparable oppositions that affect the metropolis productive.
