Subglacial hydrology in East Antarctica is poorly understood, yet may be critical to the manner in which ice flows. Data from a new regional airborne geophysical survey (ICECAP) have transformed our understanding of the topography and glaciology associated with the 287,000 km**2 Aurora Subglacial Basin in East Antarctica. Using these data, in conjunction with numerical ice sheet modeling, we present a suite of analyses that demonstrate the potential of the 1000 km-long basin as a route for subglacial water drainage from the ice sheet interior to the ice sheet margin. We present results from our analysis of basal topography, bed roughness and radar power reflectance and from our modeling of ice sheet flow and basal ice temperatures. Although no clear-cut subglacial lakes are found within the Aurora Basin itself, dozens of lake-like reflectors are observed that, in conjunction with other results reported here, support the hypothesis that the basin acts as a pathway allowing discharge from subglacial lakes near the Dome C ice divide to reach the coast via the Totten Glacier.

The construction of a Gothic vault implied the solution of several technical challenges. The literature on Gothic vault construction is quite large and its growth continues steadily. The main challenge of any structure is that, during and after construction, it must be "safe", that is, it must not collapse. Indeed, it must be amply safe, able to support different loads for long periods of time. Masonry architecture has shown its structural safety for centuries or millennia. The Pantheon of Rome stands today after almost 2,000 years without having needed any structural reinforcement (of course, the survival of any building implies continuous maintenance) . Hagia Sophia in Istanbul, finished in the 6th century AD, has withstood not only the dead loads but also many severe earthquakes . Finally, the Gothic cathedrals, with their appearance of weakness, are• more than a half millennium old. The question arises of what the source of this amazing strength is and how the illiterate master masons were able to design such daring and safe structures . This question is usually evaded in manuals of Gothic architecture. This is quite surprising, the structure being a fundamental part of Gothic buildings. The present article aims to give such an explanation, which has been studied in detail elsewhere. In the first part, the Gothic design methods "V ill be discussed. In the second part, the validity of these methods wi11 be verified within the frame of the modern theory of masonry structures . References have been reduced to a minimum to make the text simpler and more direct.

Abstract The aim was to examine the injuries sustained by Spanish football players in the First Division and to compare injury-related variables in the context of both competition and training. The injury data were prospectively collected from 16 teams (427 players) using a specific web-based survey during the 2008/2009 season. A total of 1293 injuries were identified (145 were recurring injuries). The overall injury incidence was 5.65 injuries per 1000 h of exposure. Injuries were much more common during competition than during training (43.53 vs. 3.55 injuries per 1000 h of exposure, P menor que 0.05). Most of the injuries (89.6%) involved the lower extremities, and overuse (65.7%) was the main cause. Muscle and tendon injuries were the most common types of injury (53.8%) among the players. The incidence of training injuries was greater during the pre-season and tended to decrease throughout the season, while the incidence of competition injuries increased throughout the season (all P menor que 0.05). In conclusion, the results of this study suggest the need for injury prevention protocols in the First Division of the Spanish Football League to reduce the number of overuse injuries in the muscles and tendons in the lower extremities. In addition, special attention should be paid during the pre-season and the competitive phase II (the last four months of the season) in order to prevent training and competition injuries, respectively.

The purpose of this article is to analyze the effect of hotel innovations on firm value. Specifically, this study fills a research gap in the previous literature by examining this effect through market value and by distinguishing the potentially different impacts of distinct innovation types: product, process, organization and marketing. This research contributes to consolidating the empirical evidence of hotel innovation and performance by analyzing whether distinct types of innovation lead to different levels of results. The findings show that innovations are perceived to have a positive impact on the future sales of the company: in a four-day period (0,+3), there is an increase in stock exchange returns of 1.53%. In terms of innovation types, process and marketing innovations are found to have a higher positive effect on hotel market value than product and organization innovations; which is explained by potential cost differences among innovations.

From Introduction. Regional economic disequilibria was viewed as both an obstacle to and result of integration (European Commission 1965; European Commission 1962; European Commission 1969). Even within the Treaty of Rome, the Community tried to establish mechanisms to alleviate regional inequality. However, it was not until 1975 that the main mechanism of regional policy was established as a result of British and Irish enlargement: the European Regional Development Fund (ERDF). Since then, cohesion policy has become a significant EU expenditure accounting for €347bn, or 35.7% of the total EU budget for 2007-13(European Commission Regional Policy-Info Regio 2012). It has also become a key policy linked to enlargement. The underlying principle of cohesion policy assumes that the market alone cannot solve development problems and therefore government intervention is needed. This notion is in direct contrast to the underlying principle of EU competition policy, which asserts that the free market can solve economic development problems (Meadows, interview by author, 2003). The logic underlying cohesion policy is not only counter to EU competition policy, but also regulatory policies. Unlike other EU policies, cohesion policy is not a sectoral policy, but rather territorial in nature (Leonardi, 2006). Thus at times EU regulatory policy has also unintentionally worked counter to the goals of regional policy, sometimes disadvantaging poorer regions (Dudek, 2005). As the Community has sought to ameliorate regional disparities, it meant that all levels of government: local, regional, national and supranational would need to be involved, however, member states have different territorial governance and European regional development programs have to varying degrees impacted the relationship and policy responsibility of different levels of government (Leonardi, 2006; Bachtler and Michie 1993; Marks, 1993). The very nature of regional development policy has provoked a re-examination of subsidiarity, or which level of government is the lowest and most appropriate level. The discussion of policy formulation and implementation at the lowest level possible also addresses the issue of the democratic deficit. Some argue that the closer government is to the people the more responsive and representative it is. Democracy, however, also implies that public funds are used in a transparent way and for public rather than private good. Yet, as we examine the history and current situation of EU regional funds we find that corruption and misuse still abound. Thus, to understand the history of regional policy it is imperative to look at the major transformations of the policy, how regional policy has impacted subsidiarity and the quality of democracy, become an important instrument of enlargement and contradicted or conflicted with other EU policies.

We present a 5.3-Myr stack (the ''LR04'' stack) of benthic d18O records from 57 globally distributed sites aligned by an automated graphic correlation algorithm. This is the first benthic delta18O stack composed of more than three records to extend beyond 850 ka, and we use its improved signal quality to identify 24 new marine isotope stages in the early Pliocene. We also present a new LR04 age model for the Pliocene-Pleistocene derived from tuning the delta18O stack to a simple ice model based on 21 June insolation at 65 N. Stacked sedimentation rates provide additional age model constraints to prevent overtuning. Despite a conservative tuning strategy, the LR04 benthic stack exhibits significant coherency with insolation in the obliquity band throughout the entire 5.3 Myr and in the precession band for more than half of the record. The LR04 stack contains significantly more variance in benthic delta18O than previously published stacks of the late Pleistocene as the result of higher resolution records, a better alignment technique, and a greater percentage of records from the Atlantic. Finally, the relative phases of the stack's 41- and 23-kyr components suggest that the precession component of delta18O from 2.7-1.6 Ma is primarily a deep-water temperature signal and that the phase of d18O precession response changed suddenly at 1.6 Ma.
