Capshaw Cave functions as a major stormwater runoff channel for the city of Cookeville, Tennessee, receiving inputs from several large sinkholes. Sediments deposited in the cave reflect the history of erosion and runoff from the city as it grew over the last century. At various locations in the cave, ~1 m thick sequences of flood-deposited, laminated fine sediments were observed along the modern stream. Alternating laminations observed in the upper ~40 cm of the sediment profile varied between 0.5 cm thick (10Y 7/6 yellow, fine sand) and 2.0 cm thick (10Y 3/2 very dark grayish brown silty sand) layers. Based on measurements of 137Cs activity, the upper 35 cm of sediment was deposited between 1963 (the peak year of 137Cs fallout from nuclear testing) and 2013 (the year samples were collected), at an average rate of 0.7 cm/y. A total of 23 alternating pairs of layers indicate an average flood recurrence interval of ~2.2 years between 1963 and 2013. Total Pb concentrations measured in cave sediments showed a peak at the 45 cm depth, suggesting that sediments above this level were deposited after the decline in Pb emissions in the 1970s, and showing general agreement with the timing of deposition suggested by 137Cs. Below 40 cm, the dark silty sand layers were fewer in number and increased in thickness (up to 10 cm), possibly due to changes in cave hydrology or sediment erosion from the surrounding watershed. These findings suggest that, before the 1960s, sedimentation rates were higher and floods were less frequent. After the 1960s, sedimentation rates decreased and floods became more common, probably as a result of urbanization in the watershed.

ResumoEste artigo tem por objetivo identificar e analisar práticas matemáticas inscritas em cadernos escolares de uma escola mista estadual do município de Antônio Carlos (SC), nas décadas de 1930 e 1940, com enfoque dado para as frações. São utilizadas as teorizações de Michel Foucault para nortear os preceitos teórico-metodológicos. Os resultados da pesquisa indicam práticas matemáticas desenvolvidas nessa escola obedecendo aos programas oficiais catarinenses da época, com soluções rápidas e sucintas e voltadas às tarefas de seu cotidiano. Também se observam que elas estão inseridas num contexto histórico, compreendido entre a Reforma Francisco Campos, de 1931, e o início do Movimento da Matemática Moderna, nos anos de 1960, no qual a fração recebe uma nova abordagem, distanciando-se da relação entre número e medida e aproximando-se da noção de parte-todo.Palavras-chave: Práticas matemáticas, Cadernos escolares, Frações, História da educação matemática.AbstractThis article aims to identify and analyze mathematical practices registered in school notebooks of a mixed state school in the city of Antônio Carlos (SC), in the 1930s and 1940s, focused on fractions. Michel Foucault's theorizations are used to guide theoretical and methodological precepts. The results of the research show mathematical practices developed in these schools obeying the Santa Catarina official programs of the time, with quick and succinct solutions and focused on their daily tasks. It is also observed that they are inserted in a historical context, between the Francisco Campos Reform, of 1931, and the beginning of the Modern Mathematics Movement, in the 1960s, in which the fraction receives a new approach, moving away from the relationship between number and measure and approaching the notion of part-whole.Keywords: Mathematical practices, School notebooks, Fractions, History of mathematics education.ResumenEste artículo tiene como objetivo identificar y analizar las prácticas matemáticas registradas en los cuadernos escolares de una escuela estatal mixta en la ciudad de Antônio Carlos (SC), en la década de 1930 y 1940, con un enfoque en las fracciones.

Chapter 1 situates Jackson State College in the racial history of Mississippi, emphasizing the struggle it faced against white supremacy and the balancing act its leadership performed. Determined to preserve the school, its presidents, both white and black, were forced to accept elements of racial containment. When protests emerged in Jackson in the 1960s, the Board of Trustees ensured that Jackson State’s president, Jacob Reddix, controlled student activism. When students joined Jacksonians to protest segregation in the city, he expelled them. When students voiced their political opinions, he dissolved the Student Government Association. During Freedom Summer, the Board of Trustees tightened restrictions on students. The smallest protest or rumor prompted white Jacksonians to condemn the campus as a breeding ground of criminals. In 1967 a new president, John A. Peoples, relaxed some restrictions on student life, even as the increasing influence of Black Power began to be felt on campus.

Analyses ethnic residential patterns, in terms of spatial segregation, in Paramaribo, as these developed historically, and their correlation to the changing socioeconomic position of the various ethnic groups. Authors first point out how Paramaribo is at present one of the most multiethnic and multicultural cities of the Caribbean, and discuss the continuing importance of ethnic identity and boundaries. They further describe the history of Paramaribo's development since the period of slavery and after abolition, when many Creoles migrated to the city. Hindustani started migrating in higher numbers to Paramaribo since the early 20th c., mainly to the urban periphery, and since the 1960s also more Javanese. More recently (since the 1980s) migrants to Paramaribo include Maroons, Amerindians, Chinese, and Brazilians. Authors examine in how far the residential patterns were determined by socioeconomic factors, and/or by ethnicity. They conclude that socioeconomic factors have overall become more influential in residential patterns than ethnicity. They point out that residential ethnic mixing has increased, as almost half of Paramaribo's neighbourhoods are mixed, with no dominant ethnic group, although some ethnic concentration continues, as a quarter of the neighbourhoods can be called Creole, one-fifth of them Hindustani, and Creoles (and Maroons) reside for a higher percentage in the city centre, and Hindustani and Javanese more in the urban periphery.

The paper discusses the activities of children's libraries in Tomsk in the 1960s and 70s. The main goal of this study is consider the history of children's libraries in the city and reveal the role of libraries in educational, cultural, political and ideological components of the everyday lives of young Tomsk residents. There are several reasons for addressing this problem. In the USSR, children were always not only in the care of the state, but also part of the political discourse about the happy childhood and the man of the future who was expected to live under communism. In this context, children's libraries were given a special status as places that successfully combined educational, cultural, political and ideological activities for children. The Tomsk Region has always been considered the intellectual center of Siberia. Therefore, it seems obvious that there has always been a special focus on the development of libraries in Tomsk. For example, the number of public libraries in the Tomsk Region increased from 135 in 1945 to 495 in 1964. This study addresses the history of children's libraries in the city. The thematic focus of their collections, and According to the regional archive, in the 1960– 70s, there were four active children's libraries in the city. The main ones were City Children's Library No. 1 located at 167 Lenin Avenue, and Marshak Children's Library No. 2 located at 17a Nikitina Street, The two other were smaller in size: Library No. 3 (81 Michurina) and City Children's Library No. 6 (9 Kolkhoznaya). The statistical reports of libraries demonstrate the increasing interest of young Tomsk residents in library activities: the number of readers, as well as number of visits grew from year to year. The libraries had quite diverse collections, which included not only books, but also periodicals. Some interesting observations can be made about the distribution of genres: socio-political publications are the second most popular genre, after fiction. Libraries were not only a place where children could receive and read books, but also hosted a variety of cultural, educational and leisure events, such as matinees, debates, exhibitions, and poetry evenings. There were Young Readers Clubs which arranged book discussions and meetings with interesting people. All this evidence suggests that children's libraries were an essential part of the city's social and cultural life. They acted as a kind of educational centers where young Tomsk residents could find answers to their questions. They were also places of leisure where children could spend their free time. Moreover, libraries inculcated some ideologically correct attitudes. Meetings, disputes, and quizzes held in libraries always addressed topics related to Lenin, communism, and activities of the Commuunist Party of the Soviet Union.

Sawahlunto is a mining town that enjoyed the glory due to coal exploitation by the Dutch colonial government which began in the 1880s. But in the early 1930s to the end of the 1940s, triggered by successive world economic crises (malaise) and various political upheavals during and some time after the Pacific War, this city has experienced a number of long downturns. This paper looks at the effect of economic decline and political turmoil on a city, in this case the City of Sawahlunto as a mining city. Using modern historical methods (historiography, interpretation, interpretation and writing), with an approach to the history of the city, this article reveals several things: First, in the 1930s, due to the world's crisis, coal production was dimming, this caused no new development of the city. Second, in 1942 the Pacific War took place, Japan ruled over the mining company, and Sawahlunto became worse off. Third, after Indonesia gained its independence until the end of the 1960s, Sawalunto did not receive significant improvements, except for a few rebuilt infrastructures. Thus, economic sluggishness and political riot at the global [and national] level have had a direct influence on a city at the local level.

In 2015, the beautiful jazz funeral in New Orleans for composer Allen Toussaint coincided with a debate over removing four Confederate monuments. Mayor Mitch Landrieu led the ceremony, attended by living legends of jazz, music aficionados, politicians, and everyday people. The scene captured the history and culture of the city in microcosm--a city legendary for its noisy, complicated, tradition-rich splendor. In City of a Million Dreams, Jason Berry delivers a character-driven history of New Orleans at its tricentennial. Chronicling cycles of invention, struggle, death, and rebirth, Berry reveals the city's survival as a triumph of diversity, its map-of-the-world neighborhoods marked by resilience despite hurricanes, epidemics, fires, and floods. Berry orchestrates a parade of vibrant personalities, from the founder Bienville, a warrior emblazoned with snake tattoos; to Governor William C. C. Claiborne, General Andrew Jackson, and Pere Antoine, an influential priest and secret agent of the Inquisition; Sister Gertrude Morgan, a street evangelist and visionary artist of the 1960s; and Michael White, the famous clarinetist who remade his life after losing everything in Hurricane Katrina. The textured profiles of this extraordinary cast furnish a dramatic narrative of the beloved city, famous the world over for mysterious rituals as people dance when they bury their dead.

Abstract In this paper, I examine the emergence of pop rai in western Algeria during the 1970s and the subsequent transformation of rai into a very different sound, and a national and international phenomenon. The study is based in part on an analysis of previously hard-to-find pop rai recordings now available on the internet. Pop rai’s origins are in the rural music of the male performers of bédoui music and particularly the female cheikhat. After independence, constraints were imposed on female performances, and so, during the 1960s, male singers, most famously Belkacem Bouteldja, began to record a modern version of the cheikhat repertoire. Messaoud Bellemou, a trumpet player from the city of Aïn Témouchent, played a major role in the further development of the music; he created an ensemble that included singers like Boutaïba Sghir, Belkacem Bouteldja, Hamani Hadjoum and Younes Benfissa, that modernized the instrumental backing and overall sound of western Algeria’s local folkloric music, and thereby created the genre known as pop rai. Other artists who played a role in the development of pop rai include the Oran-based Chaba Fadela, who started her career with Bellemou’s group, Cheb Khaled, and Groupe El Azhar; and from Sidi Bel Abbès, guitarist and singer Ahmed Zergui. During the 1980s, rai music became national, and producer Rachid Baba Ahmed of Tlemcen further modernized its sound through the use of electronic keyboards. By the late 1980s, rai had become international, a new generation of artists had emerged, and the ensembles and artists that forged pop rai in the 1970s were displaced. Today those artists are largely forgotten, and this critical period in the history of rai remains seriously understudied.

From the late 15th century onward, the city of Antwerp experienced an enormous demographic and economic expansion and became the commercial metropolis of the West par excellence. Merchants from Portugal, Spain, England, Germany, and other parts of Europe settled in Antwerp and gave the city a cosmopolitan character. The rapid economic growth had far reaching consequences for the city’s social and cultural life. A limited number of merchants and bankers realized big fortunes and caused a highly polarized wealth structure. At the same time, the increasing prosperity created opportunities for a broad social middle group. The economic expansion greatly stimulated cultural and artistic activities. Foreigners visiting Antwerp were struck by the elaborated and laicized school system. The book printing industry boomed too, giving Antwerp a dominant position in the Low Countries. A similar evolution happened in the realm of the arts. A contemporary observed that the best artists moved to Antwerp and commented that “art prefers to be with abundance.” The cosmopolitan character of the city, the availability of books, and the high level of schooling created an openness and a critical attitude in religious matters and contributed to the rise of Protestantism. Furthermore, from 1566 onward Antwerp played a key role in the Netherlandish, or Dutch, Revolt. In 1585, however, rebellious Antwerp surrendered to the besieging Spanish army and quickly became a stronghold of the Counter-Reformation. The closure of the Scheldt River to navigation after 1585 notwithstanding, the Antwerp economy experienced an Indian summer in the first half of the 17th century thanks to the integration of commerce into the Iberian trade system. Furthermore, art production highly profited from the construction and redecoration of churches, turning Antwerp into an international center of baroque art. The history of Antwerp’s so-called Golden Age generated much historical research. While a focus on the economic and social aspects characterized the 1960s and 1970s, the history of art and culture has drawn considerable attention in the years since then.
