The West-Pana intrusion belongs to the Paleoproterozoic Fedorova-Pana Complex of the Kola Region in NW Russia, which represents one of Europe’s most significant layered complexes in terms of total platinum group element (PGE) endowment. Numerous studies on the age of the West-Pana intrusion have been carried out in the past; however, all published U-Pb isotope ages were determined using multi-grain ID-TIMS. In this study, the mineralized Main Anorthosite Layer from the upper portion of the intrusion was dated using SHRIMP-II for the first time. High Th/U (0.9–3.7) zircons gave an upper intercept age of 2509.4 ± 6.2 Ma (2σ), whereas the lower portion of the intrusion was previously dated at 2501.5 ± 1.7 Ma, which suggests an out-of-sequence emplacement of the West-Pana intrusion. Furthermore, high-grade PGE mineralization hosted by the anorthosite layer, known as “South Reef”, can be attributed to (1) downward percolation of PGE-enriched sulfide liquid from the overlying gabbronoritic magma or (2) secondary redistribution of PGEs, which may coincide with a post-magmatic alteration event recorded by low Th/U (0.1–0.9) zircon and baddeleyite at 2476 ± 13 Ma (upper intercept).

This Focus addresses the relationship between historians and the societies they serve, particularly since the later nineteenth century when, for the first time, historians began to define themselves as a distinct professional group. One of the conclusions that emerges from the four case studies pursued here is that the independence of judgement which professionalism implies, founders the moment it is perceived by a wider public that historians are no longer providing them with the moral guidance they expect from those who have studied their pasts. It is also shown that the challenges and responses did not prove identical in any two sets of circumstances. This introduction also makes reference to general challenges to which individual contributors do not necessarily refer, but which have impacted on the work and independence of all historians.Historians, both now and in the past, have been aware that what they write is, of necessity, influenced by their personal circumstances as also by their political and social preferences. Perhaps out of recognition of this, some writers of history in all centuries, and possibly from every culture, have celebrated their ability to shape policy in the present by citing experiences from past times. Then, in the nineteenth century, as governments in the west established Public Record Offices, National Archives and National Libraries, it came to be accepted in that part of the world that historians were professionals who, having undertaken a prescribed course of training, were uniquely equipped to assess how politicians and diplomats in the past had conducted their business.

For the first time in history the three countries in Indochina—Cambodia, Laos, and Viet Nam—have started a massive effort to upgrade their transportation systems, particularly those linking each one to the others. Despite the fact that the great Mekong River runs through all three countries, natural barriers formed by the massive Annamite Mountains, which extend from the Himalayas, effectively divide the peninsula, preventing both the Chinese civilization from the east and the Indian civilization from the west from crossing the barrier. Such seclusion suited the region's socialist regimes well in the 1970s and 1980s. Since the 1990s, however, circumstances have induced these three countries to adopt more market-oriented and outward-looking policies, which created interest in expanding and strengthening the region's transportation network. In addition to the drawing up of plans for domestic transportation networks, frequent international conferences have been convened to seek cooperation among the Indochinese countries and from abroad. Many projects have been identified, and some are being implemented. The extreme neglect under which the transportation network has operated during the past two decades has made such efforts daunting. The task of upgrading transportation infrastructure in Indochina will be a priority for some time to come.

Six major rivers flow through the Kruger National Park (KNP). All these rivers originate outside and to the west of the KNP and are highly utilized. They are crucially important for the conservation of the unique natural environments of the KNP. The human population growth in the Lowveld during the past two decades brought with it the rapid expansion of irrigation farming, exotic afforestation and land grazed by domestic stock, as well as the establishment of large towns, mines, dams and industries. Along with these developments came overgrazing, erosion, over-utilization and pollution of rivers, as well as clearing of indigenous forests from large areas outside the borders of the KNP. Over-utilization of the rivers which ultimately flow through the KNP poses one of the most serious challenges to the KNP's management. This paper gives the background to the development in the catchments and highlights the problems which these have caused for the KNP. Management actions which have been taken as well as their results are discussed and solutions to certain problems proposed. Three rivers, namely the Letaba, Olifants and Sabie are respectively described as examples of an over-utilized river, a polluted river and a river which is still in a fairly good condition.

The book is about one of the biggest economic success stories that one has hardly ever heard about. It is about a perennially backward, poor, and peripheral country, which over the last twenty-five years has unexpectedly become Europe’s and a global growth champion and joined the ranks of high-income countries during the life of just one generation. It is about the lessons learned from its remarkable experience for other countries in the world, the conditions that keep countries poor, and challenges that countries need face to grow and become high-income. It is also about a new growth model that this country—Poland—and its peers in Central and Eastern Europe and elsewhere need to adopt to continue to grow and catch up with the West for the first time ever. The book emphasizes the importance of the fundamental sources of growth—institutions, culture, ideas, and leaders—in economic development. It argues that a shift from an extractive society, where the few rule for the benefit of the few, to an inclusive society, where many rule for the benefit of many, was the key to Poland’s success. It asserts that a newly emerged inclusive society will support further convergence of Poland and Central and Eastern Europe with the West and help sustain the region’s Golden Age, but moving to the core of the European economy will require further reforms and changes in Poland’s developmental DNA.

Your bed shall be the moorcock’s, and your life shall be like the hunted deer’s, and ye shall sleep with your hand upon your weapons.’ Tricked out of his inheritance, shanghaied, shipwrecked off the west coast of Scotland, David Balfour finds himself fleeing for his life in the dangerous company of Jacobite outlaw and suspected assassin Alan Breck Stewart. Their unlikely friendship is put to the test as they dodge government troops across the Scottish Highlands. Set in the aftermath of the 1745 rebellion, Kidnapped transforms the Romantic historical novel into the modern thriller. Its heart-stopping scenes of cross-country pursuit, distilled to a pure intensity in Stevenson’s prose, have become a staple of adventure stories from John Buchan to Alfred Hitchcock and Ian Fleming. Kidnapped remains as exhilarating today as when it was first published in 1886. This new edition is based on the 1895 text, incorporating Stevenson’s last thoughts about the novel before his death. It includes Stevenson’s ‘Note to Kidnapped’, reprinted for the first time since 1922.

The creation of the Islamic State in Iraq and Sham (ISIS) changed the nature of jihadism worldwide. For a few years (2014–2017) it exemplified the destructive capacity of jihadism and created a new utopia aimed at restoring the past greatness and glory of the former caliphate. It also attracted tens of thousands of young wannabe combatants of faith (mujahids, those who make jihad) toward Syria and Iraq from more than 100 countries. Its utopia was dual: not only re-creating the caliphate that would spread Islam all over the world but also creating a cohesive, imagined community (the neo-umma) that would restore patriarchal family and put an end to the crisis of modern society through an inflexible interpretation of shari‘a (Islamic laws and commandments). To achieve these goals, ISIS diversified its approach. It focused, in the West, on the rancor of the Muslim migrants’ sons and daughters, on exoticism, and on an imaginary dream world and, in the Middle East, on tribes and the Sunni/Shi‘a divide, particularly in the Iraqi and Syrian societies.

Abstract When in 1955/1956, for the first time in divided postwar Germany, a major Picasso exhibition took place in Munich, Cologne, and Hamburg, it came to be a cultural event that reached and emotionalized the German audience, media, and sciences to an unprecedented extent. The exhibition Picasso 1900 – 1955 contributed significantly to the popularization of Picasso at all levels of society and gave the German people access to modern art on a much wider scale than the first documenta held concurrently in Kassel. The undisputed eye-catcher of that spectacular exhibit was Guernica, on display in Germany for the first and only time. Its controversial reception reveals that at that time there was no intention to see the work in Germany in a memorial relationship with Germany’s own historical responsibility. Thus it virtually functioned as a symbol for a collective amnesia of the West German postwar society, whereas the socialist East of the Republic stylized the painting into an anti-fascist icon.

ADHD is a well-known, chronic disorder that persists in adulthood. During the past 20 years its existence in adults is becoming clearer, yet its dynamic aspects are rarely discussed. The treatment of adults is vital, as much as that of children; however the literature discussing it, especially its non-pharmacological aspect, is scarce.We describe the results of our treatment with drama-therapy of two groups of adults with ADHD. These groups included 11 adults (from both groups), men and women, from most socioeconomic strata, aged ≥ 60 yrs., who were diagnosed as suffering from ADHD and were treated for it for the first time in their life. Drama-therapy was selected as we believed it to be a useful method with associative, distracted ADHD patients, since it enabled the use of transitional space through non-verbal images and acts.This presentation discusses the basic themes with which patients began therapy. Interestingly, all patients, however different, shared the same themes that were built on self doubt and the pre-presumption of disappointment. The impairment related to ADHD, that was felt, but not understood, led to a strong experience of heavy losses, which we tried to define separately: of a clear path, of control, of the inner perception of borders and of the loss of an integrative inner self. All these losses were accumulated in the transitional space in a place we named “Nowhere land”.We would like to present these themes of losses and of becoming lost and to discuss their meaning.

AbstractMons. Antonio Batista Fragoso has been bishop of Crateus in Northeast Brazil for the past ten years. Eighty percent of the 360,000 people in his diocese are impoverished peasants who engage in rudimentary farming. At least half of the peasants are landless. It is among these people that Bishop Fragoso has encouraged the formation of small grassroots Christian communities that are responsible for a profound change in the patterns of Christian living in his diocese. The following is LP's translation of excerpts from a talk that Bishop Fragoso gave to his fellow bishops and priests in Managua in October, 1980. This is the first time it has appeared in English.
