We have ceased to be a nation in retreat : Margaret Thatcher e gli usi strategici del conflitto

This essay explores Margaret Thatcher\u2019s political agency and leadership style in terms of her reliance on discursive and media strategies which thrived on the \u201cconfusion\u201d of gender stereotypes and her ability to play with multiple, long-established archetypes of women in power, characterized by violent and aggressive femininity. Thatcher\u2019s frequent self-projection as a \u201cmasculine\u201d character, the \u201chonorary man\u201d of British politics, and her special grip on British public opinion and fantasies, were never disjointed from her ability to don, exploit, subvert and redirect \u201cmotherly\u2019 (or at least \u201cwomanly\u201d) performances at will, in order to serve her political agenda. Focusing on her strategic deployment of a rhetoric and discourses of aggression, divisiveness, conflict and war, the essay highlights Thatcher\u2019s ability to re-create and keep alive the idea of a national community always under siege, where extraordinary economic, disciplinary and defence measure were required in order to resist and overcome domestic and foreign \u201cenemies\u201d. The Falklands War will be taken as case study, for it provides an outstanding example of Thatcher\u2019s powerful revision of female political authority against the backdrop of the conventionally masculine, heroic imaginary of war. Her masterly and coterminous performances as war leader and \u201csuper-mother\u201d of the nation allowed for a complex and hybrid self-projection which still acts as an empowering model whose disciplinary subtext entails a nostalgic investment in imperial national history

The contribution of geomagnetic observatories and magnetic models to the study of secular variation and jerks in Antarctica

Some of the most interesting features of the geomagnetic field and its time variations are displayed in polar areas. Observatory monthly means usually provide an excellent opportunity to study the temporal changes of the magnetic field at a given location. Unfortunately, on the Antarctic continent the distribution of the permanent ground- based observatories does not permit a uniform coverage of the examined area. Furthermore, the magnetic records are characterized by intense external disturbances and noise that make the analysis of the magnetic field difficult. To improve our knowledge of the secular variation and detect the presence of secular variation impulses (geomagnetic jerks) in Antarctica, we use both observatory data and the CM4 quiet time magnetic field model. In particular CM4 improves our knowledge of geomagnetic jerks over Antarctica through the study of the sign changes of the secular acceleration maps

Radio Echo Sounding (RES) investigations at Talos Dome (East Antarctica): bedrock topography and ice thickness

Radio echo sounding measurements were collected during two Antarctic expeditions to determine the ice thickness and the sub-glacial morphology of Talos Dome in the region around 72°48'S; 159°06'E (about 6400 km2) on the edge of the East Antarctic plateau adjacent to Victoria Land in the western Ross Sea sector. The increasing interest in this region is due to the fact that in this area the ice accumulation is higher than in other sites in East Antarctica. Because of this, Talos Dome could be a new site for a project of a deep ice core drilling to obtain information on climate changes near the coast of Antarctica. In this frame, the knowledge of the bedrock topography is of great importance to choose the best location for the drilling site. In this paper, airborne radio echo sounding results from two Antarctic expeditions (1997 and 1999) are presented. Bedrock topography in bi- and three-dimensions for the Talos Dome region are discussed

Missing The Forest For The Trees: A Lack Of Upper Extremity Physical Performance Testing In Sports Physical Therapy

# Background Despite shoulder and elbow injuries being common in athletics, return to sport and reinjury rates are less than ideal. These outcomes may be driven by the absence of evidence-informed testing to determine an athlete's readiness for sport. # Purpose The purpose of this study was to explore the reported frequency of physical performance testing for return to sport readiness by physical therapists treating athletes with upper extremity injuries and to identify potential barriers that may limit use of these tests. A secondary aim was to compare practice patterns of clinicians with sports physical therapy specialty certification to clinicians without. # Study Design International, cross-sectional survey using purposive sampling. # Methods A survey instrument was created to assess the frequency of use of physical performance tests by physical therapists treating athletes with upper extremity injuries, as well as the barriers limiting the use of these tests. The 19-question online survey was distributed via email and Twitter among sports physical therapists. Independent t-tests and Chi Square analyses were conducted to determine differences in practice patterns between physical therapists with and without specialization and the frequency of potential barriers that may limit the use of these tests. # Results Four hundred ninety-eight participants met study eligibility and completed the survey. Fewer than half of participants reported using any physical performance test in making return to sport decisions for athletes with upper extremity injuries. The greatest barriers to the use of physical performance tests were a lack of equipment followed by lack of understanding of the literature, lack of time, and lack of supporting literature. Sports specialist clinicians were significantly more likely (p\<0.001) to use physical performance tests than non-specialist clinicians (71.6% versus 36.3%). # Conclusion In this survey of physical therapists (n=498), the majority admit to not using physical performance tests when making return to sport decisions for athletes with upper extremity injuries regardless of specialization. Physical therapists have an opportunity to improve the utilization physical performance testing in the upper extremity athlete in hopes of reducing injury recurrence and enhance return to sport rates. # Level of Evidence Level 3

Systematic Magnetic Observations in Italy

Istituto Nazionale di Geofisica e Vulcanologia (INGV) is responsible for systematic magnetic observations in Italy made in observatories and repeat stations. At present, two regularly working geomagnetic observatories cover central and northern Italy: L’Aquila (the main Italian observatory since 1958) and Castello Tesino (since 1964). A new observatory is, at the moment, being installed in the southern Mediterranean (near Sicily) at Lampedusa Island. Once this installation is successfully completed, the three observatories will be able to provide a full coverage of the whole Italian latitudinal extension. A network of magnetic repeat stations is regularly distributed across Italy and measurements in some locations have been made for more than a century. Since the end of the 1970’s, INGV has been developing a modern repeat station network used for the compilation of the Italian magnetic maps. The most recent survey was made between 2004 and 2005 using L’Aquila Observatory as reference

The ISIS Project: Indications for Future Near-Earth Plasma Studies through Future Galileo Satellites

The Earth’s plasmasphere variability is a consequence of the Sun’s forcing, determining our planet’s space weather. Plasmaspheric dynamics could be entirely caught only by studying together global and local proxies of the state of this extended system. The ISIS project (Inter-Satellite & In Situ plasmaspheric monitoring and modelling) aimed to design a system for the continuous monitoring of the Earth’s plasmasphere based on the future Galileo satellites. The efforts and expertise of ISC-CNR (Institute for Complex Systems of the National Research Council of Italy), INGV (Istituto Nazionale di Geofisica e Vulcanologia) and TAS-I (Thales Alenia Space - Italy) were put together in this work of assessment. ISIS Team proposed new experimental facilities of the Galileo satellites, designed to realize inter-satellite and in situ measurements to monitor global and local quantities; in particular, a scalable system of Langmuir probes was suggested, while the TEC along all possible inter-satellite ray paths throughout the plasmasphere could be monitored via phase- and group-delay analysis of inter-satellite radio signals

Pd2Si surfaces thermally enriched in silicon: Evidence of new Si:Pd bonds

Thermally induced Si accumulation onto Pd2Si surfaces has been studied for the first time with synchrotron radiation photoemission. Evidence is given of the formation of strong bonds between Si and Pd in the transition region between Pd2Si and Si. The results are discussed in view of the Pd-Si interfaces prepared by annealing in device technology

On the origin of intermittency in wave turbulence

Using standard signal processing tools, we experimentally report that intermittency of wave turbulence on the surface of a fluid occurs even when two typical large-scale coherent structures (gravity wave breakings and bursts of capillary waves on steep gravity waves) are not taken into account. We also show that intermittency depends on the power injected into the waves. The dependence of the power-law exponent of the gravity-wave spectrum on the forcing amplitude cannot be also ascribed to these coherent structures. Statistics of these both events are studied.Comment: To be published in EP
