In the acute phase of a suspected stroke, timely brain imaging with rapid and qualified interpretation is a crucial diagnostic step to inform patient management. While brain computed tomography is usually sufficient to indicate thrombolysis within the approved time window (by rapidly excluding intracranial haemorrhage), it often fails to show the actual site and extent of infarction as well as other pathologies, which may mimic a stroke. Magnetic resonance imaging (MRI) has a much higher sensitivity and specificity for ischaemic vascular brain changes and thus allows direct demonstration of the area(s) of acute ischaemic damage. This helps in the diagnosis of clinically uncertain cases, may give aetiological clues, and can also provide pathophysiologic insights into stroke evolution with respective consequences for patient treatment. The capability to rule out many other disorders that may mimic stroke is also an important asset of MRI. All these advantages make MRI the preferred tool in the workup of young individuals with suspected stroke. However, this needs ready availability and adequately tailored and short imaging protocols in order not to delay treatment.

Vaccines save between 2 million and 3 million lives each year and protect the entire population from more than a dozen life-threatening diseases. Thanks to vaccination, smallpox was eradicated in 1980, and we are on track to eradicate polio. However, despite great strides in the control of measles, one of the most contagious diseases known, the last few years have unfortunately seen an increase in cases. This is why high vaccination coverage—95% or more—is needed, posing a major technical and communication challenge for health workers. Studies show that telling people about the quality, safety, effectiveness and availability of vaccines is not enough to influence behavior change related to immunization, and in general, doesn´t increase coverage. For this reason, it´s necessary to understand the reasons why people choose not to get vaccinated or not get their children vaccinated, in order to begin a two-way respectful dialogue using the best, most effective messages. Given this context, the main objective of these guidelines is to provide tools for staff working in the field of immunization to support effective communication between health personnel and the general population, with the aim of strengthening, maintaining or recovering trust in vaccines and the immunization programs in the Region of the Americas.

This chapter looks at how on the plantations and farms of nineteenth-century Florida, enslaved people, like their counterparts throughout the South, rarely rose up in rebellion against their masters. In their daily dissidence, slaves—as Gerald W. Mullin noted for eighteenth-century slaves in Virginia—more commonly used inward or non-threatening forms of rebellion that did not undermine Florida′s slave society in any profound manner. These could involve work stoppages and feigned illnesses, among other things. Yet, enslaved Florida blacks often did not bite their tongues when expressing thoughts about their work routines. These tactics could have proven self-destructive and even fatal in a violent Florida frontier area, but slaves still used these token forms of rebellion to wrest concessions from their masters as they strove to create, preserve, and protect family and community.

This work provides a thorough overview and analysis of the increasing gap between the Americans at the top and bottom of the economic scale. Rich and Poor in America: A Reference Handbook provides an in-depth analysis of—and possible solutions for—the growing disparity between those at the top of the economic ladder and everyone else, a disparity that has reached its highest level since the 1920s. Expertly researched and written, Rich and Poor in America explores a wide range of explanations for the trend that undercuts the U.S.'s "Land of Opportunity" image, including heavy immigration, weakening labor unions, globalization, and technological change. Separate chapters look at the issue chronologically and from a global perspective, while biographical sketches provide fascinating portraits of some of the "winners" in our winner-take-all society, as well as leading scholars and activists working on this issue. copywriter rewrite: Rich and Poor in America: A Reference Handbook provides an in-depth analysis of the widening income gap in the United States—a situation where, over nearly three decades, fewer and fewer Americans have made significant financial strides while more and more have seen their real incomes remain the same or decrease. Objective, expertly researched and clearly written, Rich and Poor in America looks at a wide range of explanations for the income gap, including heavy immigration, weakening labor unions, globalization, and technological change. Separate chapters examine the trend as it has evolved over time and from a global perspective, while biographical sketches provide fascinating portraits of some of notable successful individuals as well as leading scholars and activists working on this issue.

The main milestones of the formation and development of astronomical science in Kharkiv during 1883–1945 are reconstructed on the example of the activities of the astronomical observatory of Kharkiv University. During this period, the outstanding worldview science in Kharkiv has achieved significant success: the works of Kharkiv astronomers have received world recognition; a well-known scientific planetary school has been established at the Observatory; the scientific community highly appreciated the research on the physics and chemistry of the Moon, the giant and small planets of the Solar System. The primary goal of the research is to inscribe the history of the university Observatory into the European and world context. Its purpose is to summarize the results of a comprehensive historical ad scientific study of the development of astronomical research in Kharkiv at the end of the 19th century – the first half of the 20th century and identification of ways of further scientific research. The completed research, which continues the problems of works devoted to the study of the history of astronomical science in Ukraine, focuses on expanding the well-known source base by attracting new retro-information resources. In particular, the monograph used a significant array of archival primary sources from almost twenty archival and library institutions of different countries. Most of them were introduced into scientific circulation for the first time, which allowed to determine and specify the sequence of stages of development of astronomical science in Kharkiv during the research period, to clarify and identify the little-known circumstances of the observatory life. The methodological basis of the study is the principles of historism, objectivity and a systematic approach to studying the problem. To solve specific problematic tasks in the monograph, general scientific and specially historical methods were used which allowed to study, analyze and summarize the presented factual material in a complex manner. The main sections of the monograph represent the dynamics of replenishment of the instrumental base of the university observatory, the chronology of the construction of the observatory complex of buildings at the location of the modern Scientific Research Institute of Astronomy of the V. N. Karazin Kharkiv National University. According to the author’s periodization, the stages of formation of subjects and directions of scientific work of university astronomers have been analyzed, including: seismic observations with the help of horizontal Rebeur-Paschwitz pendulums, research of the activity of the Sun, astrometric observations on the Repsold meridian circle of for the purpose of compiling a catalog of zodiac stars, studying lunar eclipses and meteor showers. The participation of university astronomers in the creation of the plan of the city of Kharkiv and its connection with the general network of precise geometric leveling of the Military Topographic Department of the General Staff; the organization of observations by an expedition of Kharkiv astronomers of the total Solar eclipse of 1914 in Henichesk; the creation of the School-workshop of precision mechanics at the Faculty of Physics and Mathematics of Kharkiv University were considered; information on the participation of Kharkiv astronomers in the events of the civil war during the Ukrainian Revolution was documented. The scientific research activity of Kharkiv astronomers during 1920-1930-s which was devoted to carrying out important astrometric works on meridian observations of star declinations by absolute methods and observations of Kopf-Rentz stars according to the programs of the International Astronomical Union; the initiation of the creation of the Catalog of faint stars; research in astrophysics aimed at studying the physical conditions on the Moon and the Sun, planets and the interstellar environment; performing long series of spectrophotometric observations of the Moon, Jupiter, Mars and Saturn under different conditions of observation; study of the kinematics of stellar systems of different order, the physical parameters and evolution of stars, the morphology of the Galaxy, the nature of the stellar subsurfaces and atmospheres, dust and gas nebulae, new stars and the variability of stars have been considered; the directions of solid works carried out in the field of celestial mechanics, devoted to the dynamics of the minor planets of the Jupiter group, the definition and improvement of the orbits of minor planets have been clarified. The development of amateur astronomy in Kharkiv, in particular, the functioning of circles and societies that directed their activities to the dissemination of astronomical knowledge, was highlighted; the participation of their representatives in astronomical observations at the Kharkiv Astronomical Observatory was emphasized. Reconstructed the development of historical events in the 1930s related to the involvement of Soviet and Western astronomers in the processes of political confrontation between the USSR and the Western world; investigated the course of circumstances that prevented the implementation of the project of creating a new modern astronomical center of national importance – the central Ukrainian observatory in Kharkiv; the participation of an expedition of Kharkiv astronomers in the observation of the «great Soviet eclipse» – the total solar eclipse of 1936 – in the North Caucasus is highlighted; established the facts of political «purges» and repressions by the People’s Commissariat for Internal Affairs ( the NKVD) in the Kharkiv Astronomical Observatory. The activity of the Kharkiv Astronomical Observatory has been documented and authentic biographical information about its representatives during the Nazi occupation of 1941–1943, the period of the German-Soviet war, has been presented; the unpopular facts of the forced collaboration of some scientists are highlighted; the process of recovery and reconstruction of the Kharkiv Astronomical Observatory after the liberation of the city is characterized. With the aim of researching the personal history of Kharkiv astronomy of the studied period, the monograph presents the results of a historical and biographical study of facts of life and scientific heritage of scientists who fully devoted themselves to Science, laid the foundations for the future development of many directions of modern astronomical research, made a significant contribution to the treasury of the national and European astronomical science, whose activities were connected with the Kharkiv Astronomical Observatory, in particular: Grigory Levytsky, Ludwig Struve, Mykola Evdokymov, Otto Struve, Mykola Barabashov, Boris Gerasimovich, Vasil Fesenkov, Oleksiy Razdolsky, Boris Ostashchenko-Kudryavtsev, Nicholas Bobrovnikov, Paraskovia Parkhomenko, Mstislav Savron, Boris Semeykin, Kostyantyn Savchenko and others (25 biographical essays are presented). A significant part of the mentioned factual material was also introduced into scientific circulation for the first time. A separate section of the monograph provides chronologically structured information that reflects the sequence of research work of the Kharkiv Astronomical Observatory employees during the period under study: from astrometric observations of stars and seismic research to spectrohelioscopic and spectroheliographic observations of the Sun and the initiation of the Kharkiv school of planetary science. It is assumed that the materials of the monograph will be used in research work devoted to the study of the process of institutionalization of astronomical research in Kharkiv at the end of the 19th century – the first half of the 20th century.
