This paper reviews the various U. S. regulations, international conventions and IMCO codes which contain damage stability requirements for tankships, chemical ships, and gas ships. A brief history of damage stability standards and background on the development of the 1973 Pollution Convention, the IMCO Chemical Code, and the IMCO Gas Code are presented. The similarities and differences among the various damage stability criteria and requirements, with emphasis on the determining philosophies and assumptions, are shown. Finally, the type of information to be presented in stability booklets and the extent of calculations required to develop that information are discussed and illustrative examples given.

The paper reports on experimental investigations which have been made on three model RO/RO ferries. One of these was based on a 1/100th scale model of the Herald of Free Enterprise ferry. The other models were modified versions of the Herald of Free Enterprise which were so modified that they did not decrease the efficient concept of the throughput of a conventional vessel. One modified model had nine longitudinal compartments, while another had six longitudinal compartments; these vessels should meet SOLAS90+50 regulations. The RO/RO ferry models with nine and six compartments had considerably better damage stability characteristics than the conventional model. The experiments were carried out on all models without the consideration of waves and wind. Small weights were placed on the model ferries, to represent motor vehicles, and water was added on the car deck. Measurements of the resulting heel angles were taken. All results were plotted on graphs and they were compared and discussed. The effect of cargo shift on the transverse damage stability of these vessels was found to be significant. The paper also contains a brief history of a few very important RO/RO ferry accidents that have taken place since the end of the Second World War.

The 20th century brought different periods in the history of Mongolia including theocracy, socialism and democracy. This article describes what renouncing the world (especially the home and the family), taking ordination, and taking monastic vows meant at the turn of the 20th century and a century later. Extracts from interviews reveal the life of pre-novices, illustrating their family backgrounds, connections with family members after ordination, and support from and towards the family. The master-disciple relationship which was of great significance in Vajrayāna tradition, is also described. As few written sources are available to study monks’ family ties, the research was based on interviews recorded with old monks who lived in monasteries in their childhood (prior to 1937), monks who were ordained in 1990, and pre-novices of the current Tantric monastic school of Gandantegčenlin Monastery. The interviews revealed similarities and differences in monastic life in given periods due to historical reasons. Though Buddhism could not attain its previous, absolutely dominant role in Mongolia after the democratic changes, nowadays tradition and innovation exist in parallel.

Категория гласа/ихоса (греч. ἦχος) как образца или модели для некоего множества напевов и категория осмогласия/октоиха (греч. ὀκτώηχος) как упорядоченного множества таких моделей составляли основу духовного песнетворчества в нескольких (если не во всех) регионах средневекового христианского мира. Сравнительная история региональных версий осмогласия еще не написана, специфика сходства и различий между ними изучена недостаточно. Задача статьи - обратить внимание на некоторые моменты, способные пролить дополнительный свет на эту специфику и, возможно, на глубинную основу системы гласов как таковой, безотносительно к особенностям ее региональных вариантов. Предполагается, что особенно богатый материал для этого может предоставить архаическая армянская гимнодия, все еще остающаяся вне поля внимания мировой науки. The category of echos (ἦχος), as a model for a certain set of tunes, and the category of octoechos (ὀκτώηχος) as an ordered set of such models, formed the basis for sacred hymnody in several (if not all) regions of medieval Christian world. A comparative history of the regional versions of octoechos has yet to be written; the specifics of similarities and differences between them are still under-researched. The aim of the present article is to draw attention to some points that could shed more light on these specifics and, perhaps, on the deeper foundations of the system of echoi as such, irrespective of the particulars characterizing its regional varieties. It is supposed that the archaic Armenian sacred hymnody, which still remains on the periphery of international scholarship, could provide an especially rich material for this purpose

The paper addresses the problem of damage stability criteria with reference to survival time, that is, the time available for evacuation of passengers on a damaged passenger roll-on/roll-off (RO/RO) vessel undergoing large-scale flooding on the car deck. The current various proposals at the International Maritime Organization (IMO) for the s factor (probability of surviving a given flooding) make no reference to survival time. The paper shows a direct link of the "prime" s factor with the time to capsize. This link has unprecedented value for a flooding control decision support system used during a crisis on board passenger ships but is of no value for the designer for whom the s factor means simply probability of surviving with adequate survival time. The paper shows how to utilize experimental data from 30-minute test runs for survival criteria based on longer duration of tests.

The conclusion focuses on the long-term ramifications of immigration reform activists’ limitations in 1965. Bringing the history of immigration reform to the present, the conclusion also reflects on the similarities and differences between immigration reform activists discussed in the book and those pushing for immigration reform during the Trump administration. Even during the most challenging times for restrictionists during the 20th Century, reformers could always count on family reunification as a priority for critics and supporters of immigration alike. That option is no longer available today. Nor can activists count on the executive office as a mitigating institution seeking common ground between the two poles. They face instead a president who uses anti-immigrant rhetoric to retain power and who bypasses Congress to change the country’s immigration and refugee policy dramatically.

The women issue is important not only in Western but also in Eastern cultures. Positioned in between the East and West, Turkey always provides an interesting collection of cases and data. Apart from the daily consumption of the women images and realities, the image of the women is also mobile when it comes to the press, and thus, this mobility is extended worldwide through the new media possibilities in the age of information. However, the contradictory images of the different cultures were displayed in the history of media as well. This chapter aims to put forward how the positioning of women in the past took place specifically in the case of Titanic news on the press of the time. The chapter questions the similarities and differences of handling women in news comparing and contrasting the Western journalism of the time and Ottoman press coverage.

This chapter explores the politics of scientific knowledge and visual representation of savanna environments in Bernhard and Michael Grzimek’s bestselling book and Academy Award–winning documentary film, Serengeti Shall Not Die (1959). It shows how the Grzimeks used their iconic airplane, nicknamed the “Flying Zebra,” to conduct ecological reconnaissance and employ aerial filmography. They depicted the Serengeti as an untouched ecosystem and a global heritage of mankind, despite its history of pastoralist land use and as a battleground between contending German and British imperial forces. Following international conventions established in London in 1933, the Grzimeks insisted that the Serengeti should encompass the entire habitat of migrating wildebeest—and not, as some officials in the Tanganyika Territory insisted, be divided to accommodate the local Maasai people’s customary cattle grazing. The Grzimeks failed to stop the redrawing of the park’s boundaries, partly because the airborne camera never expunged the Serengeti’s “ghosts of land use past.”

Although spatial thinking has long been a part of anthropological inquiry, it has waxed and waned in its perceived utility and centrality to the field. Although the papers in this volume attest to a vigorous tradition of spatial thinking in anthropology and further suggest that, for at least some branches of the field, spatial thinking and analysis are truly central to their definition and mission, it is nevertheless clear that this has not always been the case. Further, despite differences in historical trajectories of development between the two major subfields of anthropology—cultural anthropology and archaeology— in terms of the way space has been used, it is also clear that the two subfields share a number of common interests and themes that deserve discussion and exploration. This exploration is not only interesting from a purely historical perspective, but also has a very practical, down-to-earth dimension. The literature on the history of science is replete with cases of communication failures both within and between scientific disciplines. While in many cases this is merely annoying (different terms used to describe the same procedure, for instance), there are occasions when these failures lead to the creation of a highly idiosyncratic jargon used by small cliques of investigators, which clearly offers the opportunity to inhibit scholarly communication. This, in turn, can lead to redundancy of effort, failure to learn from the mistakes of others, and wasted time and money. By providing a forum in which similarities and differences can be examined, the natural tendency of scientific disciplines to form these cliques can be overcome. I intend this paper to be such a forum for an exploration of the ways in which geographic information systems (GIS) have been employed by anthropologists and archaeologists as represented by the authors of the papers presented in this volume. I will briefly describe the GIS for those readers unfamiliar with it and then turn to a review of the history of spatial thinking and the kinds of tools used to implement this thinking for each of the subdisciplines.

This chapter discusses the role of consensual dispute resolution (CDR), which allows parties to resolve their disputes outside of the judicial system, in same-sex relationship dissolutions. Two forms of CDR are mediation and collaborative law. In mediation, the parties meet with a neutral professional who helps the parties identify and resolve their disputes. In collaborative law, each party is represented by a collaborative attorney. The chapter, outlines characteristics of mediation and collaborative law, including their similarities and differences, and the tenets of a collaborative divorce. It then describes how the history of discrimination in the courts has affected LGBTQ families and made the use of CDR a more satisfactory and safe way to uncouple. It examines the unique issues that arise for some LGBTQ clients. Lastly, it reviews the skills a CDR professional needs to work with LGBTQ clients.

BEFORE the dawn of the millennium new legislative and executive authorities will have been established in Edinburgh, Cardiff and (subject to further political and other progress) in Belfast. This article analyses the nature of these constitutional initiatives, and examines their place in the unitary state which is the United Kingdom. It begins by tracing the history of constitutional union between England, Wales, Scotland, and Ireland. The legal effect of the 1998 devolution statutes is examined, in particular on the legal sovereignty of the United Kingdom Parliament. A triple constitutional and legal lock exists in the Scotland Act 1998 to ensure that the devolution settlement is the final step away from the pure unitary state which has enfolded Scotland in Great Britain. The nature and likely success of that lock are analysed in some detail. The lawmaking powers of the Scottish Parliament, the Welsh Assembly, and the Northern Ireland Assembly are assessed. The similarities and differences between each of the three devolved governments and the British Government are highlighted, and consequences and possible lessons for future government-making at Westminster are drawn. The article concludes with a peer into the possible constitutional futures for the United Kingdom.
