Performance in different athletic activities has continued to improve over time, with some athletes from diverse parts of the world registering new world records from time to time. With stiff competition from athletes from different parts of the world, constant upgrading of sports science based approaches to training and competition are employed to achieve more success. However, some approaches used to improve sports performance may pose ethical concerns and may challenge sports as a concept of celebrating natural human abilities. This book chapter interrogates the factors associated with efforts towards improvement of performance in endurance sports events, with a specific focus on marathon races, and the future implications for training, competition, and the nature of sports. While the interplay between nature and nurture determines the unique psychophysiological responses to training and competition, technological exploits leading to advanced sports products coupled with favourable natural and/or manipulated internal (body) and external environmental conditions will ensure continued improvement in performance. However, there is a need to censor commercial interest as well as safeguard safety and the nature of sports as a medium to celebrate natural human abilities.

Experts know that multilingualism is not the so-called minority phenomenon as many people think it to be. Although it is difficult to provide the exact statistical data on the multilingual speakers and distribution of multilingualism in the world, sociolinguists and linguists estimate that there are roughly around 6000 languages in the world. The focus of this book chapter is to succinctly present the sociolinguistic aspects of language choice and use of multilingual speakers in various domains. Besides, concepts such as bilingualism and multilingualism and their dynamics in the field of sociolinguistics have been critically been reviewed and presented from the theoretical and empirical perspectives. Further, some of the relevant issues related to language choice and use in multilingual speech communities in different parts of the globe are reviewed and included. Furthermore, factors inducing multilingualism among different speech communities and individuals have been reviewed and finally, recent developments and dynamics toward the spread of multilingualism in various parts of the world are also presented in the chapter.

AbstractThis book chapter provides a detailed description of the discovery, research, and validation of the case of Mr. Israel Kristal of Israel, 113, as the World’s Oldest Man titleholder for Guinness World Records. In this chapter, we show how modern scientific age validation criteria were applied to prove the credibility of the claims made about Mr. Kristal’s age. Due to the hardships Mr. Kristal faced in his early life, validating his age proved to be extremely difficult. While the first attempts to validate Mr. Kristal’s age were made in early 2014, a breakthrough in these investigative efforts did not occur until January 2016. To validate his age, the Gerontology Research Group contacted not only Mr. Kristal’s family, but also international institutions specializing in genealogical research. A special note of appreciation should go to the Jewish Records Indexing in Poland for their contributions to this investigation. As a result of this international cooperation, sufficient early-life, middle-life, and late-life evidence was obtained to meet modern validation standards. Israel Kristal was finally recognized as the oldest living man in the world on Mar. 11, 2016 (retroactive to Jan. 19, 2016). Israel Kristal is the second validated supercentenarian in the history of Israel, after Dr. Maria Pogonowska (1897–2009), who was also born in Poland. In addition, he is the current longevity record-holder of Israel.

ABSTRACT A reference standard is widely sought for use in the quantitative bioassay of pituitary gonadotrophin recovered from urine. The biologic similarity of pooled urinary extracts obtained from large numbers of subjects, utilizing groups of different age and sex, preparing and assaying the materials by varying techniques in different parts of the world, has lead to a general acceptance of such preparations as international gonadotrophin reference standards. In the present study, however, the extract of pooled urine from a small number of young women is shown to produce a significantly different bioassay response from that of the reference materials. Gonadotrophins of individual subjects likewise varied from the multiple subject standards in many instances. The cause of these differences is thought to be due to the modifying influence of non-hormonal substances extracted from urine with the gonadotrophin and not necessarily to variations in the gonadotrophins themselves. Such modifying factors might have similar effects in a comparative assay of pooled extracts contributed by many subjects, but produce significant variations when material from individual subjects is compared. It is concluded that the expression of potency of a gonadotrophic extract in terms of pooled reference material to which it is not essentially similar may diminish rather than enhance the validity of the assay.

This book charts the transformation of one of the world's great religions during an age marked by world wars, genocide, nationalism, decolonization, and powerful ideological currents, many of them hostile to Christianity. The book traces how Christianity evolved from a religion defined by the culture and politics of Europe to the expanding polycentric and multicultural faith it is today—one whose growing popular support is strongest in sub-Saharan Africa, Latin America, China, and other parts of Asia. The book sheds critical light on themes of central importance for understanding the global contours of modern Christianity, illustrating each one with contrasting case studies, usually taken from different parts of the world. Unlike other books on world Christianity, this one is not a regional survey or chronological narrative, nor does it focus on theology or ecclesiastical institutions. The book provides a history of Christianity as a popular faith experienced and lived by its adherents, telling a compelling and multifaceted story of Christendom's fortunes in Europe, North America, and across the rest of the globe. It demonstrates how Christianity has had less to fear from the onslaughts of secularism than from the readiness of Christians themselves to accommodate their faith to ideologies that privilege racial identity or radical individualism.

The central idea of Henry Kissinger's latest book, The Global System, is that the world desperately needs a new world order, otherwise geopolitical chaos threatens the world, and perhaps chaos will prevail and settle in the world. According to Kissinger, the world order was not really there at all, but what was closest to the system was the Treaty of Westphalia, which included about twenty Western European states for almost four centuries.

A river flows serenely accepting all the miseries and happiness that it comes across its journey. A tree releases oxygen for human beings despite its inner plights. The sun is never tired of its duty and gives sunlight without any interruption. Why are all these elements of nature so tuned to? Education is knowledge. Knowledge comes from learning. Learning happens through experience. Familiarity is the master of life that shapes the individual. Every individual learns from nature. Nature teaches how to sustain, withdraw and advocate the prevailing situations. Some dwell into the deep realities of nature and nurture as ideal human beings. Life is a puzzle. How to solve it is a million dollar question that can never be answered so easily. The perception of life changes from individual to individual making them either physically powerful or feeble. Society is not made of only individuals. Along with individuals it has nature, emotions, spiritual powers and superstitious beliefs which bind them. Among them the most crucial and alarming is the emotions which are interrelated to others. Alone the emotional intelligence is going to guide the life of an individual. For everyone there is an inner self which makes them conscious of their deeds. The guiding force should always force the individual to choose the right path.  Writers are the powerful people who have rightly guided the society through their ingenious pen outs.  The present article is going to focus on how the major elements bound together are dominating the individual’s self through Rabindranath Tagore’s Home and the World (1916)

The world is in a state of profound changes. One of the most likely forms of the future world pattern is polycentrism. At the stage of the formation of a new world order, it is very important to identify its key properties, identify the challenges associated with them and offer the public possible answers to them. It is proposed to consider conflictness, uncertainty and other features as properties of polycentrism. These properties entail certain challenges, the answers to them could be flexibility of diplomacy, development of international leadership and others.
