Various Shiite devotional texts to be recited in religious assemblies (majālis) commemorating the events leading to the martyrdom of the Shii Imam Ḥusain b. ʻAlī (d. 680). Each majlis (there is twenty) begins with a synoptic heading. The beginning of 17th majlis suggests that some of these texts are based on Mahdī b. Abī Zarr al-Kāshānī an-Niraqī's "Muḥarriq al-qulub (a Shiite history of the martyrs of the Prophet's family).

This paper reports the results of two studies. The purpose of the first study was to determine if lifestyle variables and past involvement in physical activity was related to current activity levels in master athletes and sedentary older adults. Retrospective interviews were conducted with 12 master athletes and 12 sedentary older adults. Results demonstrated that education level, spouse participation, smoking, and recent physical activity levels were indicators of current involvement. The second study investigated the reliability of the data collected in the retrospective interviews. Similar to results with younger samples, we confirm that lifestyle variables and physical activity involvement could be accurately recalled for a period of 25 years, making this tool a useful addition for the study of physical activity in older adults.

This paper examines the performance of the European Parliament in EU AFSJ law and policy-making from the entry into force of the Lisbon Treaty until the end of the first half of 2013. The paper situates the EP in the new post-Lisbon institutional setting, documenting its transition to ‘AFSJ decision-maker’, and its new powers to shape and make policy covering the EU’s internal and external security agenda. While the paper finds that the EP has become an active co-owner of the EU AFSJ post-Lisbon, with the Parliament demonstrating a dynamic adjustment to its new post-Lisbon role and powers, the authors identify a set of new developments and challenges that have arisen in the conduct of democratic accountability by the EP in the AFSJ since 2009, which call for critical reflection ahead of the new parliamentary term 2014-2019 and the post-2014 phase of the EU’s AFSJ.

Introduction. Iceland’s domestic politics and foreign affairs are undergoing drastic changes. After an economic crash, violent protests on the streets of Reykjavik for the first time in Iceland’s history contributed to the defeat of the government. The party system has been altered. A turn has been taken towards Europe after the United States left the island, first by closing its military base in 2006 and then by its clear stance not to assist the country in its economic difficulties. The former close relations with the superpower are unlikely ever to be restored. The EU membership application is placing severe constraints on political parties which are split on the issue and has put in jeopardy the unity of the first left majority in the Icelandic parliament, the Althingi. Society is in a state of flux after an unprecedented economic downscaling and the collapse of almost its entire financial sector – which had boomed rapidly beginning in the mid-1990s. The credibility of politicians, the parliament and the media is in ruins. Iceland’s smallness and its location on the geographical map – one could also say the geopolitical map – has had a profound influence on its domestic and foreign affairs. Iceland is closely associated with the other Nordic states and has adopted many of their domestic characteristics, with important exceptions. On the other hand, the country has come under American influence – geographically, it straddles the Mid-Atlantic rift – and has limited its participation in the European project. Its geographical location in the middle of the North Atlantic has led to a notion that the country’s culture is unique and should be protected by all available means. Politicians continue to play the ‘nationalistic uniqueness’ card with considerable success even though the country has been swept by globalization. Rapid modernization (which only really began in the Second World War with British and American occupations) and sudden engagement with the outside world (which only extended to the general public in the last quarter of the twentieth century) are still slowly but steadily making their mark on the country’s foreign policy. The country’s political discourse and foreign policy still bear the hallmark of the past, i.e. of a small and insular society This paper will address the political developments in Iceland since the 2008 economic crash and place it in a historical context. The aim is to understand Iceland’s present foreign policy and, in particular, the highly contested decision by its government in 2009 to apply for membership of the European Union. The paper is divided into five sections in addition to this introduction and the concluding remarks. First, it starts by explaining the importance in Iceland of a political discourse based on the concept of independence which dates back to the historical narrative of the settlement period. This section will also examine Iceland’s close relations with the other Nordic states – despite important differences between it and the others. Second, the paper will analyse the importance of the party system, i.e. the dominance of the centre-right in Icelandic politics, and the changed nature of the system. Third, it examines how Iceland further distinguishes itself from the other Nordic states in many important features. Fourthly, the paper analyses the country’s three main foreign policy priorities in the post-war period, i.e. extensions of the Exclusive Economic Zone, firm defence arrangements with the US and membership of NATO, and the drive for better market access for marine products – including a partial engagement in the European project. Fifthly, the paper examines how the country’s smallness, in terms of its central administrative capacity, has affected its domestic and foreign policy-making. The concluding section summarizes the main findings concerning the political and historical obstacles that the Social Democratic Alliance faces in its hard-fought battle to change the country’s European Policy.

For many years the European Union has been improving the efficient use of energy resources and yet the demand for energy in the EU continues to increase. When Europe belonged to one of the world’s key energy markets with relatively easy access to energy resources, growing energy needs were not seen as a source of concern. Today, however, as the competition for energy resources is intensifying and the global position of the EU energy market is being challenged by growing economies in the developing countries, above all China and India, the EU needs to adopt bold policies to guarantee the sustainable supply of energy. This report argues the EU needs to develop a fully-fledged external energy policy; i.e. a common, coherent, strategic approach that build bridges between the interests and needs of the EU integrated energy market on the one hand and supplier countries on the other. The EU’s external energy policy has two main objectives. The first one is to ensure a sustainable, stable and cost-effective energy supply. The second is to promote energy market integration and regulatory convergence with neighbouring countries (often but not always this supports the achievement of the first objective). However, in order to improve its effectiveness, the EU’s external energy policy needs to be seen in a broader economic and political context. Any progress in energy cooperation with third countries is contingent upon the EU’s general stance and offer to those countries.

Aufbauend auf dem analytischen Tool des Totalen Krieges (vgl. den Artikel des Autors zu Controversy Total War in 1914-1918-Online) werden im vorliegenden Beitrag die Anstrengungen Chinas im Ersten Weltkrieg zu denjenigen anderer nicht europäischer Länder wie Australien, Südafrika oder Indien in Bezug gesetzt. Dabei wird das Ziel verfolgt, den globalen Charakter eines Konfliktes deutlich zu machen, der zurecht als erster Weltkrieg bezeichnet wird und in welchem China sicherlich eine weit bedeutsamere Rolle spielte, als es gemeinhin in der Historiographie dargestellt wird. Ursprünglich wurde der Beitrag als Antwort auf die Frage konzipiert, warum nicht nur China für eine Globalgeschichte des Ersten Weltkrieges von Bedeutung war. Im Verlauf der Übersetzung wurde der Titel dahingehend angepasst, dass stärker die Bedeutung von Chinas Rolle im Ersten Weltkrieg betont wurde.

Electronic books (e-book) are an interesting option compared to classic paper books. Most e-reading devices of the first generation were based on e-ink technology. With the appearance of the Apple iPad on the market, TFT-LCDs became important in the field of e-reading. Both technologies have advantages and disadvantages but the question remains whether one or the other technology is better for reading. In the present study we analyzed and compared reading behavior when reading on e-inkreader (e-ink displays) and on tablets (TFT-LCDs) as measured by eye-tracking. The results suggest that the reading behavior on tablets is indeed very similar to the reading behavior on e-ink-reader. Participants showed no difference in fixation duration. Significant differences in reading speed and in the proportion of regressive saccades suggest that tablets, under special artificial light conditions, may even provide better legibility.

The Miocene Climatic Optimum (~17-14.7 Ma) represents one of several major interruptions in the long-term cooling trend of the past 50 million years. To date, the processes driving high-amplitude climate variability and sustaining global warmth during this remarkable interval remain highly enigmatic. We present high-resolution benthic foraminiferal and bulk carbonate stable isotope records in an exceptional, continuous, carbonate-rich sedimentary archive (Integrated Ocean Drilling Program Site U1337, eastern equatorial Pacific Ocean), which offer a new view of climate evolution over the onset of the Climatic Optimum. A sharp decline in d18O and d13C at ~16.9 Ma, contemporaneous with a massive increase in carbonate dissolution, demonstrates that abrupt warming was coupled to an intense perturbation of the carbon cycle. The rapid recovery in d13C at ~16.7 Ma, ~200 k.y. after the beginning of the MCO, marks the onset of the first carbon isotope maximum within the long-lasting "Monterey Excursion". These results lend support to the notion that atmospheric pCO2 variations drove profound changes in the global carbon reservoir through the Climatic Optimum, implying a delicate balance between changing CO2 fluxes, rates of silicate weathering and global carbon sequestration. Comparison with a high-resolution d13C record spanning the onset of the Cretaceous Oceanic Anoxic Event 1a (~120 Ma ago) reveals common forcing factors and climatic responses, providing a long-term perspective to understand climate-carbon cycle feedbacks during warmer periods of Earth's climate with markedly different atmospheric CO2 concentrations.

Fine-grained clay subfractions (SFs) with particle size of <0.1, 0.1-0.2, 0.2-0.3, 0.3-0.6, 0.6-2.0, and 2-5 µm separated from claystone of Upper Precambrian Pumanskaya and Poropelonskaya formations on the Srednii Peninsula were studied by transmission electron microscopy, X-ray diffraction, and Rb-Sr methods. All subfractions consist of low-temperature illite and chlorite, and contribution of chlorite decreases with diminishing particle size. The crystallinity index and I002/I001 ratio increase from coarse- to fine-grained SFs. Leaching by ammonium acetate solution and Rb-Sr systematics in combination with mineralogical and morphological data indicate that illite in Upper Proterozoic claystone from the Srednii Peninsula formed during three time intervals: 810-830, 610-620, and about 570 Ma ago. The first generation of this mineral with low Rb/Sr ratio dominates in coarse-grained SFs while the second and third generations with a high Rb/Sr ratio prevail in fine-grained SFs. All of three generations are known in Poropelon claystone, whereas Puman claystone contains only illite of the first and second generations. Geological processes responsible for multistage illite evolution in claystones are discussed.

On Vermilion Sea Expedition two research vessels among which the R/V Spencer F. Baird conducted a geological and geophysical exploration of the Gulf of California from February to May, 1959. Support was obtained from the Office of Naval Research and the Bureau of Ships of the U. S. Navy and from a grant of the American Petroleum Institute. Study of the canyons was one feature of the first part of the expedition. Submarine canyon studies were directed by Francis P. Shepard, Professor of Submarine Geology, aboard the research vessel Spencer F. Baird. The expedition found that the narrow channel between Angel de la Guarda Island, toward the head of the Gulf, and the peninsula is scoured almost free of sediments by strong currents. On the other side of Angel de la Guarda Island, between it and the mainland, one of the dredge hauls brought up a manganese nodule. It came from a depth of approximately 1500 feet. This is the shallowest water in which the nodules have been found. Studies have been under way some time on the feasibility of mining such nodules from the sea floor. They contain cobalt, nickel, copper and other valuable metals.
