Strontium isotopic compositions of acetic acid (HOAc) leachate fractions of eight manganese oxide deposits from the modern seafloor, and of twenty-one buried manganese nodules from Cretaceous to Recent sediments in DSDP/ODP cores were measured. ratios of HOAc leachates in all modern seafloor manganese oxides of various origins are identical with present seawater. The ratios of the HOAc leachates of buried nodules from DSDP/ODP cores are significantly lower than those of nodules from the modern seafloor and are mostly identical with coeval seawater values estimated from the age of associated sediments. It is suggested that the buried nodules in DSDP/ODP cores are not artifacts transported from the present seafloor during the drilling process, but are in situ fossil deposits from the past deep-sea floor during Cretaceous to Quaternary periods. The formation of deep-sea fossil nodules prior to the formation of Antarctic Bottom Water (AABW) indicates that the circulation of oxygenated deep seawaters have activately deposited manganese oxides since the Eocene Epoch, or earlier.

Numerous studies have found a positive connection between learners’ motivation towards foreign language and foreign language achievement. The present study examines the role of motivation in receptive vocabulary breadth (size) of two groups of Spanish learners of different ages, but all with 734 hours of instruction in English as a Foreign Language (EFL): a CLIL (Content and Language Integrated Learning) group in primary education and a non-CLIL (or EFL) group in secondary education. Most students in both groups were found to be highly motivated. The primary CLIL group slightly overcame the secondary non-CLIL group with respect to the mean general motivation but this is a non-significant difference. The secondary group surpass significantly the primary group in receptive vocabulary size. No relationship between the receptive vocabulary knowledge and general motivation is found in the primary CLIL group. On the other hand, a positive significant connection, although a very small one, is identified for the secondary non-CLIL group. We will discuss on the type of test, the age of students and the type of instruction as variables that could be influencing the results.

A particular scientific world view has become dominant, influential and successful in modern sciences today. Science and technology have transformed the way we view ourselves, our societies and our place in the cosmos. However, just as science and technology seem to be at the peak of their power, unexpected problems are disrupting the sciences from within. This reflects a deeper and more serious problem regarding scientific inquiry. Science is being held back by old assumptions that have become dogmas, the biggest of which is that science already knows all the answers, and only the details need to be worked out. A transformational paradigm shift is required from a mechanistic world view to an organic world view to better address the challenges of the new millenium.

While historically notions of democracy have varied widely, democratic peace theory has generally defined it in procedural terms. This article takes a close look at the Anglo-French confrontation of 1840. I show that while leaders on both sides were prepared to risk war to gain bargaining advantages, only the French left really wanted to fight. Why? By today's criteria, Britain was incontestably more democratic, with its monarch's powers far more restricted and its suffrage several times as large. Nevertheless, both sides considered France more democratic, with French republicans despising Britain as an aristocratic oligarchy. While Spencer Weart is right to argue that democratic republics may be hostile to oligarchic ones, they will not necessarily define each other according to modern procedural criteria. Instead, they may judge regimes by the broader social structures that shape power relationships and by outcomes, possibly explaining wars or near misses between democracies.

The Late Cretaceous to Modern tectonic evolution of central and eastern California has been studied for many decades, with published work generally focusing on specific geographic areas and time periods. The resulting literature leaves the reader, whether graduate student, faculty member, or layperson, wondering what a coherently integrated tectonic evolution might look like, or if it would be at all possible to undertake such a task. This question is the common thread weaving together the four studies presented in this work. Each of the individual chapters is targeted at a specific location and time period which I have identified as a critical yet missing link in piecing together a coherent regional tectonic story. In the first chapter, we re-discover a set of major west down normal faults running along the western slope of the southern Sierra, the western Sierra fault system (WSFS). We show that one of these faults was offset by roughly a kilometer in Eocene time, and that this activity directly resulted in the incision of much of the relief present in modern Kings Canyon. The second chapter is a basement landscape and thermochronometric study of the hanging wall of the WSFS. New data from this study area provide a significant westward expansion of basement thermochronometric data from the southern Sierra Nevada batholith. Thermal modeling results of these data provide critical new constraints on the early exhumation of the Sierra Nevada batholith, and in the context of the results from Chapter I, allow us to piece together a coherent chronology of tectonic forcings and landscape evolution for the southern Sierra Nevada. In the third chapter, I present a study of the surface rupture of the 1999 Hector Mine earthquake, a dextral strike slip event on a fault in the Eastern California Shear Zone (ECSZ). New constraints on the active tectonics in ECSZ will help future studies better resolve the enigmatic mismatch between geologic slip rates and geodetically determined regional rates. Chapter IV is a magnetostratigraphic pilot study of the Paleocene Goler Formation. This study provides strong evidence that continued investigation will yield new constraints on the depositional age of the only fossil-bearing Paleocene terrestrial deposit on the west coast of North America. Each of these studies aims to provide important new data at critical missing links in the tectonic evolution of central and eastern California.

Ideas of childhood and citizenship stood at the center of the Soviet Union’s empire-building project during the 1920s and 1930s. After the 1917 Revolution the Bolsheviks were faced with the challenge of establishing a new state structure and governing a vast territory inherited from its tsarist predecessor. In the early years of the Soviet project, new leaders enlisted a cadre of professionals tasked with not only creating the norms of childhood and the everyday, but also implementing policies to modernize habits and values of the empire’s younger citizens. To understand how children became a prime focus of Soviet imperial and ethno-cultural politics, my dissertation employs discourse analysis and compares the ways in which Soviet imperial policies were implemented in two ethnically different regions: the Buddhist Republic of Kalmykia as the colonial case study and Moscow as the Metropole. The current project examines newspapers, treatises, and inspectors’ reports over the span of twenty years. It finds that the Bolsheviks’ initial values and discourses in the realm of children’s education, health, leisure and nutrition, all which were scientifically designed to transform children into ideal Soviet and modern citizens, changed over time as a result of the competing ideologies among local elites and the challenges they faced while intervening in children’s everyday lives. The most significant conclusion in this dissertation reveals that, contrary to previous scholarly arguments, the modernization projects that took place in Moscow and Kalmykia were more similar in the challenges and outcomes that local officials faced when implementing state policies.
