This thesis addresses continuity and change in the manufacture and use of decorative metalwork in the Iron Age (200-1900 AD) of southern Africa, within a framework of archival studies and artefact studies theory. The thesis adopted a direct historical approach which exploited the huge database of existing information to create typologies of objects and processing techniques that are prominent in ethno-historical sources of the 19th and 20th centuries. This process enabled for the first time, a comprehensive mapping of object typologies and techniques of manufacture by ethnic groups thereby allowing cross cultural comparisons. Subsequently, the study explored the typology of objects utilized further back in the time of the Early Iron Age using archaeological evidence. It demonstrated that most of the objects used in the Iron Age were similar to those that were used in the 19th century. However, new innovations were made along the way with metals and alloys being constantly added to the range of materials worked. A dedicated visual study of fabrication techniques employed in the manufacture of ethnographic materials housed at Iziko Museum of Cape Town was carried out. The techniques gleaned from the macroscopic study were compared with those metallographically documented in the literature for the manufacture of Iron Age objects, further exposing continuity and change in metal fabrication. The social, economic and political role of decorative metalwork was hardly static, and varied from context to context and group to group.

This original analysis of the workings ofSoviet state security organs under Lenin and Stalin addresses a series of questions that have long resisted satisfactory answers. Why did political repression affect so many people, most of them ordinary citizens? Why did repression come in waves or cycles? Why were economic and petty crimes regarded as political crimes? What was the reason for relying on extra-judicial tribunals? And what motivated the extreme harshness of punishments, including the widespread use of the death penalty?Through an approach that synthesizes history and economics, Paul Gregory develops systematic explanations for the way terror was applied, how terror agents were recruited, how they carried out their jobs, and how they were motivated. The book draws on extensive, recently opened archives of the Gulag administration, the Politburo, and state security agencies themselves to illuminate in new ways terror and repression in the Soviet Union as well as dictatorships in other times and places

This research explores the priorities of the gender equity commission in New York City over forty-five years. Archival commission data was organized thematically to understand the history of gender equity and suggest future possibilities for gender equity beyond New York City. In our historical analysis, we see an expansion of the definition of gender and an adoption of an intersectional approach to gender. We identify four historical gender priorities: sexual harassment and violence, pay equity and economic advancement, health and safety, and gender recognition and celebration. To address systemic issues of gender inequity, we recommend local level administrators embed an intersectional approach in their policies and programming and move away from the commission model to one of a permanent office or agency. These recommendations will better equip municipalities with the resources to increase gender equity, particularly during COVID-19 recovery.

This original analysis of the workings of the Soviet state security organs under Lenin and Stalin illuminates the ways in which terror and repression in the Soviet Union were used during this period.

Time is a ubiquitous but often omitted variable in career selection decisions. This study investigates the impact of temporal elements on career selection decisions, thus advancing our understanding of both career decision making and the impact of timing on decision making. We investigate the influence of timing and duration of experience with career options on career selection decisions in an archival study using medical residents' rotation schedules. We also investigate factors that mitigate the influence of timing on career selection decisions by examining the interaction of timing with the duration of experience and the diversity of options that an individual experiences. Conditional logit results indicate that decisions often based on career and individual attributes are significantly influenced by the timing and duration of options even when controlling for option attributes. Additionally, significant interactions between timing and diversity of experience and timing and duration of experience revealed boundary conditions for timing. Individuals were more likely to select later-appearing career options when they appeared for a greater duration or when they experienced a greater diversity of options in their schedule. Results illustrate that schedules over which individuals have no control can influence consequential decisions.

The season's records of a Canadian ice hockey league provided the data for an investigation of aggression in relation to crowd size and competition. Crowd size was positively related to aggression in one season but not in the preceding year. Aggression increased over the three periods of game play but not across the season. League standing and the score existing during play were both significantly related to aggression. However, the aggression displayed by a team in a match was unrelated to their league standing vis a vis that of their opponents. The results are generally discussed within a frustration-aggression framework.

How do buildings contribute to an organization's sense of what it is? In this article, we present the findings of a major archival study of an iconic university building to answer this question. Founded in the 19th century as a college for women, the building is analysed as a gendered space that embodies meanings that are selectively deployed and adapted by the present-day, now co-educational, university. By bringing together concepts of space and history so as to examine 'space in history' we show how over long periods of time what buildings 'say' about an organization change so that the past is both a legacy and a resource for shifting organizational identity.

Aluminum alloys are very interesting witnesses of industrial and technical development. The first ever developed was Duralumin, a light metal with good mechanical properties. In the 1930s, the rise of nationalism stimulated research and development, generating various aluminum alloys. This work reports the comparison of two versions of aluminum alloys, which were found in collected parts of WWII crashed aircraft from four nations: a Messerschmitt Bf 109 (DE), a Dewoitine D.520 (FR), and a P-51 Mustang (USA) and an Avro Lancaster (United Kingdom). The first version of alloy with magnesium content below or equal to 1 wt.% and the second version with higher magnesium content (1.5 wt.%), were identified as respectively AlCuMg1, AlCuMg2 in Germany ; Duralumin, Duralumin F.R. in France ; Hiduminium DU Brand, Hiduminium 72 in the UK and 17S, 24S in the USA. This study uses a multiscale approach based on historical research complimented by laboratory analyses of materials directly collected on the crashed aircraft. It allows a comparison and a better knowledge of the alloys used in each nations: their chemical composition, designations, microstructure, and mechanical properties are investigated.
