Text from page 3: "Introduction: The following study was undertaken at the suggestion of Dr.G .S .Dodds, ,with the intent of discovering the factors which determine the distribution of a group of our local fauna, the land gastropods. This group has been a favorite object of study with naturalists for the past century, and a great mass of literature exists on isolated collections made the country over. In Missouri a certain amount of collecting has been done, probably exhausting largely the possibilities so far as species are concerned. However, some interesting additions to our knowle[d]ge of the regional distribution have been ad1ed in the course of the present study, as will be noted later. Greger (1905) has made extensive collections in Callaway County, Pilsbfy and Ferris (1S06) in the Ozark Region, and Sampson (1913) over most of the State. There are besides, more general collections, as those of Binney (1885), in which mention is made of Missouri shells. Heretofore no attempt has been made to correlate the information scattered. Thru these papers, or to study the distribution from an ecological standpoint, and there has not been an intensive study of a single region in Missouri."

Contemporary identity in Thailand is prominently configured through an allegiance of reformed Buddhism with the modern Thai state. What is not well understood, however, is the centrality of “comparative religion” to the construction of this naturalized religionationalist identity, for interreligious study in Siam has been an integral component of modern Thai identity since the mid-nineteenth century. First, the emergence of “religion” as an object of study in modern Thailand is explored here, in an effort to detail the genealogy of this field for the first time. The articulation of Thai religious identity is identified as a response to intellectual challenges from colonial influences, especially the reproofs of Buddhism by Christian missionaries and Orientalist scholarship on religion. Thai Buddhist intellectuals responded to these challenges by robustly countering that Theravada Buddhism was, in fact, superior to Christianity and other religions. Finally, I explore the contentions between the Thai Buddhist apologetics and their opponents as a genealogy of the knowledge in comparative religion in Siam over the past century and a half. Given this genealogy, the field of comparative religion in Thailand is revealed as being far from a disinterested pursuit of knowledge; rather, it is part of the formation and reaffirmation of Thai national identity.

The object of criminology is to investigate and explicate conducts contradicting social order. The roots of this science originate from the thoughts of the first generation of sensible men who were able to reflect over aggressive actions, suchlike murders or any other criminal conducts breaking social rules. In terms of moral, religious, philosophical or political outlook, the inception of criminology is even more ancient whereas from the doctrinal point of view, the origin of this science has been considered the XIX century. Later on, from the middle of the past century and on, while it was developing gradually, issues related to criminal offenses and felons were treated legally, considerations that had an effect into the future of the science in word. Criminal act may be related to political, legal, constabulary, medical, psychological or sociological issues. Deviation and criminal offenses should be analysed in terms of all these domains and precisely this is where criminology should be justified as a science, considering the pro and contrary attitudes, regarding its role as an auxiliary discipline. Therefore, it is crucial for the science of criminology not to experience any critical situations of other social sciences and not get apart from its base ideals. It should be linked more with the reality, including all actors, the society and its values, culture, etc., and respond to questions related to its own object of study, acknowledging limitations and fully playing its role in an unstable society in continuous transformation while considering the effects of its intrusions.

Seven zoonoses — human infections of animal origin — have emerged from the Coronaviridae family in the past century, including three viruses responsible for significant human mortality (SARS-CoV, MERS-CoV, and SARS-CoV-2) in the past twenty years alone. These three viruses, in addition to two older CoV zoonoses (HCoV-229E and HCoV-NL63) are believed to be originally derived from wild bat reservoir species. We review the molecular biology of the bat-derived Alpha- and Betacoronavirus genera, highlighting features that contribute to their potential for cross-species emergence, including the use of well-conserved mammalian host cell machinery for cell entry and a unique capacity for adaptation to novel host environments after host switching. The adaptive capacity of coronaviruses largely results from their large genomes, which reduce the risk of deleterious mutational errors and facilitate range-expanding recombination events by offering heightened redundancy in essential genetic material. Large CoV genomes are made possible by the unique proofreading capacity encoded for their RNA-dependent polymerase. We find that bat-borne SARS-related coronaviruses in the subgenus Sarbecovirus, the source clade for SARS-CoV and SARS-CoV-2, present a particularly poignant pandemic threat, due to the extraordinary viral genetic diversity represented among several sympatric species of their horseshoe bat hosts. To date, Sarbecovirus surveillance has been almost entirely restricted to China. More vigorous field research efforts tracking the circulation of Sarbecoviruses specifically and Betacoronaviruses more generally is needed across a broader global range if we are to avoid future repeats of the COVID-19 pandemic.

Abstract. Low-density lipoprotein cholesterol (LDL-C) has been proven to be a causal factor of atherosclerosis and, along with other triggers like inflammation, the most frequent reason for peripheral arterial disease. Moreover, a linear correlation between LDL-C concentration and cardiovascular outcome in high-risk patients could be established during the past century. After the development of statins, numerous randomized trials have shown the superiority for LDL-C reduction and hence the decrease in cardiovascular outcomes including mortality. Over the past decades it became evident that more intense LDL-C lowering, by either the use of highly potent statin supplements or by additional cholesterol absorption inhibitor application, accounted for an even more profound cardiovascular risk reduction. Proprotein convertase subtilisin/kexin type 9 (PCSK9), a serin protease with effect on the LDL receptor cycle leading to its degradation and therefore preventing continuing LDL-C clearance from the blood, is the target of a newly developed monoclonal antibody facilitating astounding LDL-C reduction far below to what has been set as target level by recent ESC/EAS guidelines in management of dyslipidaemias. Large randomized outcome trials including subjects with PAD so far have been able to prove significant and even more intense cardiovascular risk reduction via further LDL-C debasement on top of high-intensity statin medication. Another approach for LDL-C reduction is a silencing interfering RNA muting the translation of PCSK9 intracellularly. Moreover, PCSK9 concentrations are elevated in cells involved in plaque composition, so the potency of intracellular PCSK9 inhibition and therefore prevention or reversal of plaques may provide this mechanism of action on PCSK9 with additional beneficial effects on cells involved in plaque formation. Thus, simultaneous application of statins and PCSK9 inhibitors promise to reduce cardiovascular event burden by both LDL-C reduction and pleiotropic effects of both agents.

One of the central questions in international relations today is how we should conceive of state sovereignty. The notion of sovereignty—’supreme authority within a territory’, as Daniel Philpott defines it—emerged after the Treaty of Westphalia in 1648 as a result of which the late medieval crisis of pluralism was settled. But recent changes in the international order, such as technological advances that have spurred globalization and the emerging norm of the Responsibility to Protect, have cast the notion of sovereignty into an unclear light. The purpose of this paper is to contribute to the current debate regarding sovereignty by exploring two schools of thought on the matter: first, three Catholic scholars from the past century—Luigi Sturzo, Jacques Maritain, and John Courtney Murray, S.J.—taken as representative of Catholic tradition; second, a number of contemporary political theorists of cosmopolitan democracy. The paper argues that there is a confluence between the Catholic thinkers and the cosmopolitan democrats regarding their understanding of state sovereignty and that, taken together, the two schools have much to contribute not only to our current understanding of sovereignty, but also to the future of global governance.

Over the past century, democracy spread around the world in turbulent bursts of change, sweeping across national borders in dramatic cascades of revolution and reform. This book offers a new global-oriented explanation for this wavelike spread and retreat—not only of democracy but also of its twentieth-century rivals, fascism, and communism. The book argues that waves of regime change are driven by the aftermath of cataclysmic disruptions to the international system. These hegemonic shocks, marked by the sudden rise and fall of great powers, have been essential and often-neglected drivers of domestic transformations. Though rare and fleeting, they not only repeatedly alter the global hierarchy of powerful states but also create unique and powerful opportunities for sweeping national reforms—by triggering military impositions, swiftly changing the incentives of domestic actors, or transforming the basis of political legitimacy itself. As a result, the evolution of modern regimes cannot be fully understood without examining the consequences of clashes between great powers, which repeatedly—and often unsuccessfully—sought to cajole, inspire, and intimidate other states into joining their camps.

Students of the land ownership patterns in Pakistan have always been hampered by extreme lack of data, neither the 1960 census nor the 1972 census reveal anything about the actual ownership structure of land. Khan's book goes some distance in providing numbers on land ownership (for 1971 and 1976), and also documents methods and failures of land reform efforts over the past century in Pakistan, disaggregated to show efforts in this regard in both the provinces of Sind and Punjab. The book actually provides an overwhelming amount of data - some 87 pages of charts and tables document a book of under 200 pages of text.

Abstract Background The larynx has multiple composite functions which include phonation, airway protection, and sensory control of respiration. Stenosis of the larynx and trachea were first recorded by O’Dwyer in 1885 and by Colles in 1886, respectively. Initially, the aetiology of laryngotracheal stenosis was predominantly infective. Currently, the leading cause is iatrogenic injury to the laryngotracheal complex secondary to prolonged ventilation in an intensive care unit. Main body Laryngotracheal stenosis is a complex and diverse disease. It poses a major challenge to the surgeon and can present as an airway emergency. Management typically demands the combined involvement of various disciplines including otorhinolaryngology, cardiothoracic surgery, anaesthesiology, interventional pulmonology, and radiology. Both the disease and its management can impact upon respiration, voice, and swallowing. The incidence of iatrogenic laryngotracheal stenosis has reflected the evolution of airway and intensive care whilst airway surgery has advanced concurrently over the past century. Correction of laryngotracheal stenosis requires expansion of the airway lumen; this is achieved by either endoscopic or open surgery. We review the relevant basic science, aetiopathogenesis, diagnosis, management, and treatment outcomes of LTS. Conclusion The choice of surgical procedure in the management of laryngotracheal stenosis is often dictated by the individual anatomy and function of the larynx and trachea, together with patient factors and available facilities. Regardless of how the surgeon chooses to approach these lesions, prevention of iatrogenic laryngotracheal damage remains of primary importance.
