Abstract Applications of molecular techniques have become integral to most fields of biological research, including evolutionary biology. Over the past two decades, studies of molecular genetics of foraminifers have emerged to enhance taxonomic identification with broad applications, including biodiversity, environmental assessments, and paleoceanographic studies. However, the results are widely scattered across the literature, thereby inhibiting advances in such research on foraminifers, especially regionally. In this review, we discuss the developments and contributions in the field of molecular genetics as applied to foraminifers, offering a guide to beginners in this area of research. Furthermore, this review highlights new opportunities for foraminiferal research that will pave the way for future studies in this field.

Abstract Recent molecular studies of fetal hemoglobin (HbF) regulation have reinvigorated the field and shown promise for the development of clinical HbF inducers to be used in patients with β-thalassemia and sickle cell disease. However, while numerous promising inducers of HbF have been studied in the past in β-thalassemia patient populations, with limited success in some cases, no universally effective agents have been found. Here we examine the clinical studies of such inducers in an attempt to systematically review the field. We examine trials of agents, including 5-azacytidine, hydroxyurea, and short-chain fatty acids. This review highlights the heterogeneity of clinical studies done on these agents, including both the patient populations examined and the study end points. By examining the published studies of these agents, we hope to provide a resource that will be valuable for the design of future studies of HbF inducers in β-thalassemia patient populations.

The particles used in radiation therapy are part of a larger universe of particles discovered by experimental physicists. May of these particles are themselves composed of particles. Understanding the way particles interact, and the forces underlying their interactions, is basic to the quest to understand the universe. High-energy physics studies in the past have identified the particles used in medicine; future studies may identify still others, but if not, may contribute to a better knowledge of the milieu in which medicine and other human endeavors exist.

AbstractThe paper describes a number of molecular methods used in the past and now to analyze forest tree species. Taking into account the economic importance of forest trees and in view of the timber economy, wood properties and characteristics are essential factors subjected to control, observation and research. Molecular techniques that support traditional selection methods allow for genetic diversity analyses considering a range of research aspects. The development of these techniques at the turn of the last two decades has enabled wide-ranging use of molecular data in studies on forest tree populations. On the example of pine (Pinus L.), the paper presents data based on molecular studies as well as a variety of possibilities to apply the obtained results.

Los medios sociales son un fenómeno que está cambiando la forma en la que las personas nos comunicamos y relacionamos, con muchos millones de usuarios en todo el mundo.  En el contexto de la gestión del deporte, los medios sociales están desempeñando actualmente un papel cada vez más relevante en el día a día de clubes, atletas, federaciones, empresas, investigadores, etc. Sin embargo, los estudios realizados hasta el momento sobre medios sociales indican que hay una falta de consenso teórico respecto al término, confundiéndolo en muchas ocasiones con el significado de otros conceptos vinculados a los mismos, algo que puede estar limitando el desarrollo de todo el potencial que tienen. Así, en este trabajo se presenta una propuesta conceptual para clarificar el concepto “medios sociales”, que pueda ser una base para la realización de futuros estudios que ayuden a los profesionales del campo de la gestión del deporte a aprovechar todas las oportunidades que los medios sociales ofrecen en los distintos ámbitos de la gestión.Abstract. Social Media is a phenomenon that is changing the way that people communicate and relate among others, with many millions of users around the world. In the context of Sport Management, Social Media currently is playing a role increasingly more relevant in the day to day of clubs, athletes, federations, companies, researchers, etc. Nevertheless, the studies done in the past to the present about Social Media suggest that there is a lack of theoretical consensus regarding the term, confusing it many times with the meaning of other concepts related to them, something that could be limiting the developmental potential that it has. Thus, in this work it is presented one conceptual proposal to clarify the concept “Social Media” that could become a point of study for of future studies that help professionals in the Sport Management field to take advantage of the opportunities that Social Media offers in the different areas of management.

First Time

Studies of the origin and diversification of major groups of plants and animals are contentious topics in current evolutionary biology. This includes the study of the timing and relationships of the two major clades of extant mammals – marsupials and placentals. Molecular studies concerned with marsupial and placental origin and diversification can be at odds with the fossil record. Such studies are, however, not a recent phenomenon. Over 150 years ago Charles Darwin weighed two alternative views on the origin of marsupials and placentals. Less than a year after the publication of On the origin of species, Darwin outlined these in a letter to Charles Lyell dated 23 September 1860. The letter concluded with two competing phylogenetic diagrams. One showed marsupials as ancestral to both living marsupials and placentals, whereas the other showed a non-marsupial, non-placental as being ancestral to both living marsupials and placentals. These two diagrams are published here for the first time. These are the only such competing phylogenetic diagrams that Darwin is known to have produced. In addition to examining the question of mammalian origins in this letter and in other manuscript notes discussed here, Darwin confronted the broader issue as to whether major groups of animals had a single origin (monophyly) or were the result of “continuous creation” as advocated for some groups by Richard Owen. Charles Lyell had held similar views to those of Owen, but it is clear from correspondence with Darwin that he was beginning to accept the idea of monophyly of major groups.

At a time when the Union between Scotland and England is once again under the spotlight, Remembering the Past in Nineteenth-Century Scotland examines the way in which Scotland’s national heroes were once remembered as champions of both Scottish and British patriotism. Whereas 19th-century Scotland is popularly depicted as a mire of sentimental Jacobitism and kow-towing unionism, this book shows how Scotland’s national heroes were once the embodiment of a consistent, expressive and robust view of Scottish nationality. Whether celebrating the legacy of William Wallace and Robert Bruce, the reformer John Knox, the Covenanters, 19th-century Scots rooted their national heroes in a Presbyterian and unionist view of Scotland’s past. Examined through the prism of commemoration, this book uncovers collective memories of Scotland’s past entirely opposed to 21st-century assumptions of medieval proto-nationalism and Calvinist misery. Detailed studies of 19th-century commemoration of Scotland’s national heroes Uncovers an all but forgotten interpretation of these ‘great Scots’ Shines a new light on the mindset of nineteenth-century Scottish national identity as being comfortably Scottish and British Overturns the prevailing view of Victorian Scottishness as parochial, sentimental tartanry

The world-wide use of scleral contact lenses has dramatically increased over the past 10 year and has changed the way that we manage patients with corneal irregularity. Successfully fitting them can be challenging especially for eyes that have significant asymmetries of the cornea or sclera. The future of scleral lens fitting is utilizing corneo-scleral topography to accurately measure the anterior ocular surface and then using software to design lenses that identically match the scleral surface and evenly vault the cornea. This process allows the practitioner to efficiently fit a customized scleral lens that successfully provides the patient with comfortable wear and improved vision.

This article examines the development of Wagnerism in late-nineteenth-century Spain, focusing on how it became an integral part of Catalan nationalism. The reception of Wagner's music and ideas in Spain was determined by the country's uneven economic development and the weakness of its musical and political institutions—the same weaknesses that were responsible for the rise of Catalan nationalism. Lack of a symphonic culture in Spain meant that audiences were not prepared to comprehend Wagner's complexity, but that same complexity made Wagner's ideas acceptable to Spanish reformers who saw in the composer an exemplar of the European ideas needed to fix Spanish problems. Thus, when Wagner's operas were first staged in Spain, the Teatro Real de Madrid stressed Wagner's continuity with operas of the past; however, critics and audiences engaged with the works as difficult forms of modern music. The rejection of Wagner in the Spanish capital cleared the way for his ideas to be adopted in Catalonia. A similar dynamic occurred as Spanish composers tried to meld Wagner into their attempts to build a nationalist school of opera composition. The failure of Tomás Bréton's Los amantes de Teruel and Garín cleared the way for Felip Pedrell's more successful theoretical fusion of Wagnerism and nationalism. While Pedrell's opera Els Pirineus was a failure, his explanation of how Wagner's ideals and nationalism could be fused in the treatise Por nuestra música cemented the link between Catalan culture and Wagnerism.

Abstract Are historic sites and house museums destined to go the way of Oldsmobiles and floppy disks?? Visitation has trended downwards for thirty years. Theories abound, but no one really knows why. To launch a discussion of the problem in the pages of The Public Historian, Cary Carson cautions against the pessimistic view that the past is simply passéé. Instead he offers a ““Plan B”” that takes account of the new way that learners today organize information to make history meaningful.
