The world-wide use of scleral contact lenses has dramatically increased over the past 10 year and has changed the way that we manage patients with corneal irregularity. Successfully fitting them can be challenging especially for eyes that have significant asymmetries of the cornea or sclera. The future of scleral lens fitting is utilizing corneo-scleral topography to accurately measure the anterior ocular surface and then using software to design lenses that identically match the scleral surface and evenly vault the cornea. This process allows the practitioner to efficiently fit a customized scleral lens that successfully provides the patient with comfortable wear and improved vision.

The article deals with a fragment of a lecture by V.V. Bibikhin, in which eternity is interpreted as a constant renewal, the young-new. The new present, the “now”, makes the preceding present different, thereby turning it into the past. This "now" does not exist in the way of being and is recognized only as the boundary between the past and the future. But it touches us, captures us. The new can't be planned, it can only be allowed, let be. The allowing is a risk, because the unknown will always fall out, something that you cannot prepare beforehand, prepare a way to deal with it. However, in the new we always recognize the same thing. Also to be ready for the new is to be ready for the generosity of being, which gives more and more. Being gives space and time to appear. The non-appeared, the different, seems to us separated with a line, a boundary. And we imagine eternity as something being abroad, beyond the line of time. But for Bibikhin, this is a meeting with the boundary itself, which is different both to what is located on one side of the boundary and to what is on the other. Eternity is not there, “beyond the line”, but here and now: it exists by its absence. Absolutely different, boundary, line, eternity — not just different, but is different, new each time. That is why Bibikhin's eternity is the young-new itself.

This chapter examines the Islamic State’s conceptualization of history and the future in relation this movement’s understanding of eschatology and the ‘End of Times’. Drawing on a veritable stream of jihadist literature, this chapter sheds light on the organization’s theorization of history, and the ways in which the Islamic State’s consistent jihadist millenarianism echoes an incessant dialectic between the past and the future to the detriment of a depreciated and sacrificed present. Adraoui demonstrates the way in which the Islamic State’s fundamentalist (mis-)interpretation of Islamic prophetic discourse merges terrestrial and celestial time, which is used to justify and exacerbate the use of extreme violence in pursuit of the organization’s aggressive political aims.

This essay is about concepts of time and the past among the Maya Indians of Yucatan in southeastern Mexico. It explores how these concepts fit into the Maya's general view of the way the world works and how they relate to certain dynamics of Maya history—as we define history—during their pre-Hispanic and colonial past. One inspiration has been the often baffling written records the Maya have left, from which we try to quarry historical facts without always enquiring what the records meant to the people who produced them. The other is the reminder, provided by recent historical work from anthropologists, that people do not record their past so much as construct it, with an eye to the present, and at the same time use that past in molding the present.

The incidence of individualist attitudes and reduced social kepedlian and others. It all becomes an indicator of the lunturnya attitude of nationalism, especially among the younger generation successor to relay the struggle of a nation. Through teaching history students capable of developing competence to think in chronological order and having knowledge about the past that can be used to understand and explain the developmental process and change people and diversity socio-culture in order find and cultivate identity nation in the society the world. Teaching history asked students realizes the diversity life experiences in each society and the way different viewpoint against its past to understand the present and build knowledge and understanding to face the future.

In this chapter, we are mainly interested in ways that use of the Internet can promote helpful, legitimate, and practical support to teachers, students, and others interested in education for peace, conflict resolution, and violence prevention. The World Wide Web, a powerful global network, has immense capacity to influence people (especially children) that can be compared to the influence of television. Research that has been done on television viewing shows that it can have positive and negative effects on behavior beginning in early childhood. It does not affect everyone in the same way—variables such as age, socioeconomic status, and identification with television characters all play significant roles in how content affects a child. The Internet and other interactive media are similar to television by way of underlying factors (such as observational learning, attitudes, and arousal) that influence behavior. Over the past several decades, some of the most profound changes in the way we live have come from the revolution in information technology (IT). A wide range of technologies has not only made it easier to communicate but also to send and utilize information. These devices have not stayed in the province of institutions or specialists but have found their way into common use. From cell phones and personal digital assistants to computers (just to touch on some of the most common of these technologies), they have changed the way ordinary people interact and behave. Their effects have been profound, as reflected in the speed with which these technologies have evolved and insinuated themselves into everyday life. Perhaps the most important of these technologies is the personal computer (PC). In itself, the rise of the PC was a dramatic event, allowing more people to apply the capabilities of the computer to small business, personal activity, and schoolwork. But in the past decade, other information technologies that utilize the PC, the most important of which are the World Wide Web and electronic mail (e-mail), have appeared and promise further large-scale uses.

In their essays published in the Silver Anniversary Issue (SAI) of the Journal of Macromarketing (2006), George Fisk and Mark Peterson independently outlined the current state of the discipline and made a list of visionary recommendations that would help macromarketers adapt and respond to the changing markets, marketing, and societies. These recommendations ranged from repositioning the discipline around the ideas of societal development to leading the way across disciplines toward achieving a sustainable world. Based on a thorough content analysis of the articles published in the Journal of Macromarketing since the SAI, we aim to report the extent to which macromarketing scholarship has responded to the recommendations of Fisk and Peterson. Utilizing the findings, we make a list of new recommendations that can assist macromarketers in fulfilling their mission of ‘saving the world’.

As I come to the end of five years’ training as an Aeronautical Engineer, several thoughts come to mind, both about my training up to the present time and the future of the aerospace industry in which I am about to serve.During the past ten years, the aerospace industry has seen many changes, not only in the form of amalgamations and project cancellations, but also in the way it must face the future. More recently it has seen the publication of the Plowden Report with all its implications. Although for many the future paints a gloomy picture, at no time has the thought of leaving the world of aeronautics been farther from my mind than it is now.

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.

We can now edit genomes. The technique, which involves cutting and pasting DNA code into the genome, is faster and cheaper than traditional genetic engineering and can be used on almost any animal or plant. What will this technology mean for the future? It may pave the way to banishing many diseases, and help feed the burgeoning population of the world. Woolly mammoths may again roam the tundra. But are there also risks? Might a nightmarish world of bioterrorism and rogue synthetic organisms await? John Parrington reports on the astonishing revolution underway in genetic engineering and why it matters to us all.
