Legacy systems migration in the small liberal arts educational institution

Wampler, Douglas R. January 2003 (has links)
With new technologies arriving at an ever-increasing rate, legacy systems migration has become a growing research area. However there are few if any studies that analyze a comprehensive actual migration in progress. Legacy system migrations commonly fail and typically fail in the planning phase unbeknownst to their project managers. Possessing information on other successes and problems would aid in mitigating these failures.The Value and Significance of the ProblemThe purpose of this research is to initially document an actual legacy systems migration for a small liberal arts educational institution and analyze the successes and failures to identify their underlying cause in order to enforce or discourage certain practices. There are very few software/hardware migration studies, if any that are based on actual data. For this reason this study provides the academic community with an important data point for analysis.The MethodThe migration under consideration is an Administrative Systems Upgrade at DePauw University. The current system that has had minor upgrades is approximately twenty years old. The planned migration has a three-year scope. The planning phase started on March 2002 and finished on March 2003. Important documents that will be analyzed to form a basis for analysis will be a white paper entitled Employment of Technology to Improve Administrative Operations: Assessment and Recommendations, produced by an external consultant, the resulting actual migration plan, discussions with the project manager and related technical staff who are involved with the migration. RisksSince the research will conclude before the completion of the DePauw Administrative Systems Upgrade, this study will be limited to the tasks completed within the timeframe. As with studying any real system success of the study may be affected by:Completion of assigned milestones within the project itself;Input from end users in the form of interviews or surveys;Input from IT staff involved in the upgrade in the form of interviews or surveys.The portion of the DePauw Administrative Systems Upgrade that falls outside the scope of this research may be the topic of future research. / Department of Computer Science

Population growth in a high amenity area : migration and socio-economic change in Cornwall

Kowalczuk, Katarzyna January 2011 (has links)
The thesis provides a deeper understanding of migration flows to high amenity areas using the example of migration to and from Cornwall. Cornwall is a remote, non-metropolitan county which has been experiencing very strong population growth since the 1970s almost solely due to in-migration. There are several aspects of the project that should contribute to an understanding of internal migration in England and Wales. First, a cohort analysis of migrants brings insights into the migration strategies of in-migrants and out-migrants throughout the period. Using the case of Cornwall allows the examination of migration patterns in a peripheral location where commuting opportunities are limited, and allows comparison with a more accessible rural area, Wiltshire. Secondly, through the creation of a new area type classification the project helps to explore the environmental dimension of migration. The typology is used to investigate the residential patterns of migrants and non-migrants and to test the hypothesis that environmental preferences are significant in the choice by in-migrants of where to live. Finally, The research investigates some pressing issues in Cornwall, issues which are relevant also for other non-metropolitan areas, such as the shortage of affordable housing, the detrimental impact of tourism and poor economic development, and their links with migration. The research focuses especially on labour market problems and housing need, due to their policy relevance. Comparisons between the migrant and non-migrant populations provide the basis for estimating the impacts of migration on the restructuring of labour and housing markets in Cornwall.

Social and cultural constructions of communities in South Yorkshire colliery settlements : the mining households of the Darfield and Wombwell district, c.1851-1900

Walker, Andrew Guyon January 1994 (has links)
Much of the literature relating to the history of miners has been written from a union orientated perspective. In this study a broader understanding of the lives of miners and their families is sought. Notions of community and communal belonging are central throughout the investigation. The extent of migration is considered. Clear evidence of residential clustering of migrants is uncovered. This had a significant impact upon community development within the settlements. The study acknowledges the centrality of the workplace in mining communities. Primary evidence suggests, though, that the mining workplace was not a cohesive social unit. Divisions within the workplace were as significant as those bet ween capital and labour. Longstanding, rigid divisions between grades of mining employees were uncovered which impacted upon their lives outside work. An examination of women's lives within the settlements questions the general assertion that they played an economically passive role within mining settlements. Women participated actively in the public life of the settlements through their involvement in mining disputes and other communal expressions of approbation, such as rough music. Religious and leisure activities revealed much about how individuals sought to construct their own identities and those of their settlements. Both boundaries of belonging and the triumph of custom over capitalist relations were affirmed through events such as celebrations. The study reveals the composite belonging. Individuals engaged in the annual feast nature of community a multiplicity of communities ranging from the micro-community of the family to the macro-community of the nation. The nature of individuals' communal participation was determined by factors such as their: age; gender; workplace position; and marital status. Communal belonging was fluid. Particular aspects of communal identity fluctuated in significance depending upon circumstance.

The transition of adult Atlantic salmon (Salmo salar L.) from saltwater to freshwater

Barbour, Andrew J. S. January 1985 (has links)
Aspects of the behaviour of adult Atlantic salmon in estuaries, while on their spawning migration has been investigated using a salinity telemetric system. Eighteen fish were tracked in total in different Scottish estuaries. Studies involving the displacement of salmon from freshwater back into higher salinities on the River North Esk, Montrose showed fast movement through the estuary back into freshwater (5h), movement being initiated by the sensing of low salinities or the start of the flood tide. Tracking in the Dornoch Firth at Bonar Bridge (a channel type estuary) showed fish maintaining one position against both flood and ebb tides, experiencing salinities fluctuating widely about the isosmotic point. The qualitative assessment of salmon on passage through the estuary of the freshwater discharge of a non-natal river was also demonstrated, repeated entries of a very brief nature (21s) being recorded. The position held by salmon whilst on suspended migration in an estuary was recorded, no sampling of the freshwater discharge being undertaken on a tidal basis. The resting metabolic rate of farmed salmon of different stages of sexual development was recorded in saltwater, and on transfer to freshwater. Maturing fish exhibited a raised metabolic rate in saltwater, suggesting increased osmoregulatory costs. This was in contrast to non-maturing fish. The cannulation of wild salmon subjected to fluctuating salinities was undertaken. Plasma electrolyte levels and osmolalities of fish subjected to cyclic salinities were intermediate between salt-adapted and freshwater-adapted values, showing only small fluctuations. An inability to osmoregulate successfully in high salinities following 'stress' events was recorded in maturing farmed and coastally caught wild salmon, suggesting a maladaption to that environment. By contrast, non-maturing farmed salmon exhibited a greater degree of euryhalinity. Examination by electron scanning microscopy of apical pit structure of gill chloride cells supports the idea that increasing maturity or freshwater exposure reduces tolerance to saltwater. It is concluded that Atlantic salmon are euryhaline during at least part of their oceanic feeding phase, and on arrival in coastal waters on the spawning migration require no period of acclimitisation to freshwater. A reduction in tolerance to high salinities linked to advancing maturation/ freshwater exposure would thus serve to ensure river entry.

Berättelser om hemlandet, migrationen och framtiden : En fenomenologisk studie om att leva utanför sitt hemland

Shatri, Florenta, Mikullovci, Elma January 2017 (has links)
Syftet med uppsatsen har varit att söka förståelse för hur migranter som lämnar sitt land upplever flytten till ett nytt land. I vår uppsats har det varit viktigt att lägga fokus på det som intervjupersonerna tagit fram som betydelsefullt i deras liv. Vad de har för erfarenheter och upplevelser från två länder samt hur deras liv ser ut idag. I uppsatsen finns ett försök att anta ett fenomenologiskt tankesätt, där aspekter av fenomenologin lyfts upp. Uppsatsen utgår från tre kvinnors livsberättelser. Intervjuerna har transkriberats och analyserats utifrån socialpsykologiska teorier. Tolkningen och analysen av intervjuerna redovisas i fem olika teman som i en kronologisk ordning ger en djupare förståelse för intervjupersonernas livsberättelser. Resultatet visar hur dessa kvinnor har upplevt svårigheterna med att migrera möta ny kultur där nya normer och värderingar dyker upp. Resultaten visar också hur dessa kvinnor känner ett inre utanförskap, där de menar att de alltid kommer vara främlingar i andras ögon.
