The railway track system is the platform by which loads from moving trains are transferred to the underlying soil or supporting infrastructure such as bridges. The most common type of railway track system is ballasted track, which has been in use for over a century. Ballasted track has proved versatile. It can be constructed using locally available materials and with modifications to the rails and sleepers, crossings transferring trains from one route to another can be created. The structure of a ballasted track system consists of two main parts. The upper portion, termed the superstructure, comprises the rails, fastenings and sleepers. It is formed of components whose shape, stiffness and strength are designed and closely controlled. Below the superstructure is the substructure, which comprises the ballast and sub-ballast. Although the materials used in the substructure may have been specified, their engineering properties and geometric placement are less well controlled. In this chapter, we will explore how a typical ballasted track system transfers load to the ground and the ways in which the track form deteriorates, requiring maintenance and eventually renewal.

The treatment and care of persons with a disability should and must be all encompassing. With the expansion of the knowledge that proper dieting can make a difference in the individual’s development and quality of life, attention must be focused on using proper food intake to remediate the negative impact of a disability. Food is related to proper healthcare; therefore, we must include proper nutrition in working with learners with exceptionalities. We must add to the list of treatments not only educational intervention, social interaction, and independent living, but also food intake. This chapter looks at the dietary needs of several disabling conditions, and addresses how particular dietary food selections help in their development and their ability to learn integration, playing skills with others, and working independently when called on to do so. Therefore, for the purposes of this chapter, we focus on exceptionalities such as cognitive disability, autism spectrum disorder (ASD), Down syndrome, attention deficit hyperactivity disorder (ADHD), muscular dystrophy, and cystic fibrosis.

The worldwide environmental crisis has also influenced the field of literary studies. Posthumanism and ecocriticism is a new way of reading in which the anthropocentric approach and the binary oppositions such as human/non-human, wild/tame and natural/cultural are overcome. Posthumanism pays attention to all sorts of non-human life, animals, for sure, but aliens and robots are included too, while ecocriticism is concerned with the role and function of nature in literary texts. The chapter offers an ecocritical approach of Robinson Crusoe (Defoe) and Friday (Tournier). Rereading these novels we see that nature, or the elements, make up an ‘actant’ equal to the human characters and a special interest is created in the mutual conflicts which arise between nature and the human characters.

Robinson Crusoe (Defoe, 1719) is considered by many as an appropriate book to allow pupils to escape from or be shielded from the negative influence of civilization. Like Robinson on his island pupils should learn from experience. Defoe’s work was so popular it inspired a whole series of imitations called ‘Robinsonnades’ and many of them were edited specifically for children. But is Robinson Crusoe a valuable book from an ecological point of view? How does Robinson relate to nature? Does the novel focus on nature or rather on the human hero seeking to control and tame the environment?

In 1967, the French author Michel Tournier reworked the Crusoe myth in Vendredi ou les limbes du Pacifique (Friday or the Pacific Rim), followed by a parallel text for children Vendredi ou la vie sauvage (Friday or the Wild Life, 1971). In both novels Robinson’s black servant, Friday, initiates his colonial master into alternative ways of living, dismantling civilization and restoring nature. That same deconstruction of the idea of Western superiority fits well with the postcolonial philosophy that attacks the logic of domination and its hierarchical dichotomy: white above coloured.

This longitudinal case study affords opportunistic infra-cross-cultural and gendered comparisons of foodways within the fourth-world Saami societies across four north-European nation-states and through two generations. The study centers on 44 years of ethnographic research in arctic Norway, among both nomadic reindeer-herding and sedentary Saami together with their nearest neighbors within and without northernmost Norway.

General ethnographic immersion, from five years in duration down to single months or weeks, since early 1972, provides qualitative and quantitative data relevant to gender and food, collected in the two local languages, and supplemented by archeological and historical records as well as literatures from contiguous areas.

Two generations ago, most families, nomadic, or settled, could remember being self-sufficient with respect to food, and to lesser extents to clothing and shelter. Women’s roles in food acquisition and preparation have expanded in recent times. Some families, given choices largely made by wives and mothers, may today have a diet comparable with that in other parts of the West.

This holistic ethnographic research continues indefinitely. Any ethnography is both enabled and limited by its investigator and by local social relations, in this case synergistic and positive.

By the close of the 20th century, Saami researchers joined others in social science, often focusing on their indigenous culture and language. These provide usually corroborating and always fascinating data for outsiders, and many anecdotal narratives illustrating these data.

This is a two-voice autoethnographic dialogue about Rousseau's Confessions and their relevance for the contemporary autoethnograpy. The paper examines the possibility that Rousseau was not only the creator of modern autobiography but also a forerunner of autoethnography. Many features of the Rousseau's masterpiece are analyzed and systematically compared to our contemporary autoethnographic sensibility: the purposes which brought him to write an outstandingly detailed description of his life; the fact that he acknowledges autobiography as the only source of true knowledge; his obsession for sincerity and his strong will to disclose all the truth about his own life to his readers (included the dreadful things that he did); the authority that he assigned to the readers in deciding about the truthfulness of his tale; his concern for the ethical issues and the care of the others; and the therapeutic value that he recognized to the practice of writing about themselves. In the end, Jean-Jacques was not only extraordinarily able to use his emotions to analyze human nature, but also he was a radical autobiographer at the limits of intransigence. His considerations on the value of autobiography can help us greatly to legitimize contemporary autoethnographic practice.
