Cultures of collecting: Maori curio collecting in Murihiku, 1865-1975

Samson, J.O. (James Oliver), n/a January 2003 (has links)
The ambivalence of many prehistorians toward curio collections has meant that, although they recognise some of their shortcomings, they nevertheless use collections as if they had qualities of archaeological assemblages. In this dissertation it is posited and then demonstrated that curio collections are very different entities to archaeological assemblages. In order to use collections in valid constructions of New Zealand�s pre-European past, the processes that led to their formation need to be understood. It is only then that issues of representation can be addressed. In order to better understand the collecting process, a study of the activity of 24 curio collectors who operated in the Murihiku region of southern New Zealand during the period between 1865 and 1975 was undertaken. The study was structured about two key notions: the idea of the �filter� and the idea that tools and ornaments have a �life history� that extends from the time that raw material was selected for the manufacture to the present. The notion of the filter made possible a determination of the effects of particular behaviours on patterns of collector selectivity and the extent and nature of provenance recording; and the extended concept of life history recognised that material culture functions in multiple cultural and chronological contexts-within both indigenous and post-contact spheres. Examination of the collecting process led to the identification of five curio collecting paradigms: curio collecting for the acquisition of social status, curio collecting for financial return, curio collecting as an adjunct to natural history collecting, curio collecting as an adjunct to historical recording, and ethnological or culture-area curio collecting. Filtering processes associated with each paradigm resulted in particular, but not always distinctive, patterns of curio selectivity and styles of provenance recording. A switch in the focus of attention from examination of curio collectng processes generally to the study of the filtering processes that shaped collections from a specific archaeological site-the pre-European Otago Peninsula site of Little Papanui (J44/1)- enabled some evaluation of individuual collection representation. A database recording up to 19 attributes for each of 6282 curios localised to �Little Papanui� in Otago Museum enabled 31 dedicated or �ardent� collectors who operated at the site to be identified. These 31 dedicated collectors were grouped according to the paradigm that best described their collecting behaviour. It was found that the greater proportion of these dedicated collectors (n=12, 39%) had been influenced by the ethnological or culture-area collecting paradigm. These 12 collectors were responsible for recovering a remarkable 5645 curios or nearly ninety-percent (89.86%) of the meta-collection. Because curio collections lack meaningfully recorded stratigraphic provenance, it is the technological and social context in which tools and ornaments functioned that must become the focus of curio collection studies. Appropriate studies of technological and social and context focus upon evaluations of raw material sourcing, evaluations of manufacture technique and assessments of tool and ornament use and reuse (and integrative combinations of these modes of study). These sorts of evaluation require large collections compiled in the least selective manner possible and the collections need to be reliably localised to specific sites. Collections compiled by the ethnological or culture-area collectors have these qualities. Collections compiled within other paradigms lack locality information and were assembled in highly selective manners.

A presente pesquisa objetivou avaliar a percepção que os catadores de materiais recicláveis associados e informais detêm sobre qualidade de vida, observando-se a relação com os indicadores utilizados no Brasil. Este estudo considerou os princípios da pesquisa qualitativa, do tipo participante, desenvolvido com 15 catadores de materiais recicláveis associados à ARENSA- Associação de Catadores de Materiais Recicláveis da Comunidade Nossa Senhora Aparecida (100%), 20 catadores de materiais recicláveis informais (100 %) e 60 moradores participantes da coleta seletiva no bairro Malvinas (21%), em Campina Grande-PB. Os dados foram coletados através de entrevista semiestruturada, aplicação do questionário Whoqol – Bref adaptado e acompanhamento do exercício profissional. Os dados foram analisados de forma qualitativa e quantitativa. Este último utilizando o programa Statistical Package for the Social Sciences (SPSS) versão 20.0. Foram aplicados os testes de Shapiro-Wilk para verificação da normalidade dos dados do Whoqol- Bref adaptado e o teste não para métrico de Kruskal Wallis. Nos resultados observou-se o predomínio do gênero feminino entre os associados (67%) e moradores (78,3%), enquanto aos informais prevaleceu o gênero masculino (55%). A percepção que os catadores de materiais recicláveis associados e informais apresentam sobre qualidade de vida está intrinsecamente conectada aos aspectos de saúde. Os indicadores citados foram: alimentação saudável, dinheiro, emprego, estudo, lazer, moradia, saúde e segurança. No acompanhamento do exercício profissional dos grupos estudados verificou-se que as condições de infraestrutura não atendem às normas regulamentadoras do Ministério do Trabalho NR 24/78. Considerando os dados do questionário WHOQOL– Abreviado, foram obtidos resultados estatisticamente significantes (ƿ<0,05) com relação a doze variáveis, dentre as quais: necessidade de tratamento médico; segurança no trabalho; renda suficiente para suas necessidades; satisfação com a alimentação e qualidade de vida. Constatou-se que a percepção de qualidade de vida dos catadores de materiais recicláveis associados e informais que atuam no bairro Malvinas, em Campina Grande-PB condiz com os indicadores de propostos na literatura. Convém ressaltar que estes indicadores não refletem integralmente o cenário que os profissionais estão inseridos, revelando o que eles almejam adquirir ou alcançar para obter qualidade de vida. Conclui-se que os catadores de materiais recicláveis detêm a percepção de qualidade de vida condizente com os indicadores utilizados no Brasil, mas as condições precárias de trabalho que estão submetidos não os permitem usufruir de qualidade de vida adequada. / Life quality is a subjective term that covers several meanings, transmitting knowledge, experience and individual and collective values. This research aimed to evaluate the perception that collectors of recyclable materials and associated informal hold on quality of life, observing the relationship with the indicators used in Brazil. This study considered the principles of qualitative research, participant type, developed with 15 waste pickers associated with ARENSA- Recyclable Materials Collectors Association of Community Nossa Senhora Aparecida (100%), 20 pickers informal recyclable materials (100%) and 60 participants residents of selective collection in the Malvinas neighborhood (21%) in Campina Grande-PB. Data were collected through semistructured interviews, application of WHOQOL questionnaire - adapted Bref and monitoring of professional practice. The data were analyzed qualitatively and quantitatively. The latter using the Statistical Package for Social Sciences (SPSS) version 20.0. The Shapiro-Wilk test to verify the normality of WHOQOL Bref data adapted and the test not to metric of Kruskal Wallis test were applied. The results observed the predominance of females among the members (67%) and residents (78.3%), while the informal prevailed males (55%). The perception that associates and informal collectors of recyclable materials have on quality of life is intrinsically connected to health aspects. Of the indicators were healthy food, money, employment, study, leisure, housing, health and safety. Monitoring of the professional practice of the groups it was found that the infrastructure conditions do not meet the regulatory standards of the Ministry of Labor NR 24/78. Considering questionnaire data, WHOQOL- Abbreviated, statistically significant results were obtained (ƿ <0.05) with respect to twelve variables, among which: the need for medical treatment; safety at work; enough income to their needs; satisfaction with the power and quality of life. It was found that the perception of quality of life of members and informal waste pickers who work in the neighborhood Malvinas, Campina Grande-PB consistent with the proposed indicators in the literature. It is worth mentioning that these indicators do not fully reflect the scenario that professionals are inserted, revealing what they desire to acquire or achieve for quality of life. It is concluded that the waste pickers hold the perception of quality of life consistent with the indicators used in Brazil, but the poor working conditions that are submitted do not allow the use of adequate quality of life.

Alternative energy supply study for a cottage in Vifors

Lumbier Fernandez, Mikel January 2018 (has links)
The present master thesis was done during the spring of 2018. A cottage located in Vifors is studied with regard to its heating requirements. At the time of the study, the house could not be inhabited the whole year because there was no tap hot water available and the space heating demand was covered by electricity. Thus, an alternative heating supply is required to be developed. As a strategic prerequisite, the solution should be achieved considering both solar thermal collectors and a heat pump.First, the characteristics of the building were collected/determined in order to obtain the total heating demand per month and hence annually. Parameters such as the U-values, roof orientation, room dimensions, ventilation rates and internal gains were required to configure the building model in the software IDA ICE 4.8. In addition, the amount of tap hot water required per year was determined as 17 m3 per year. Cold water at 5 °C had to be heated until 55 °C to obtain the tap hot water.Once the heating requirements were known, the most suitable solution was to use a combi system (solar thermal collectors and a heat pump). Solar energy could fulfil the demand in the summer and the heat pump provided energy in the winter. For a commercial model of the flat solar thermal collector (Vitosol 100-F) the solar system was sized according to the heating demand in the summer time. The maximum energy that could be obtained from the solar collectors in summer was calculated, the rest of the demand had to be fulfilled by a heat pump, model WPL-18 E.The achieved solution is compounded by the heat pump and 3 solar thermal collectors with a surface of 2.33 m2 each. The solar energy obtained is 1 843 kWh per year, which covers 9 % of the total annual heating demand (20 098 kWh). However, the 98 % of the heating demand during the summertime comes from the solar collectors. The investment cost is 113 900 SEK and the payback period is estimated in 8 years.

Handle with care : historical geographies and difficult cultural legacies of egg-collecting

Cole, Edward January 2016 (has links)
This thesis offers an examination of egg-collecting, which was a very popular pastime in Britain from the Victorian era well into the twentieth century. Collectors, both young and old, would often spend whole days and sometimes longer trips in a wide variety of different habitats, from sea shores to moorlands, wetlands to craggy mountainsides, searching for birds’ nests and the bounty to be found within them. Once collectors had found and taken eggs, they emptied out the contents; hence, they were really eggshell collectors. Some egg collectors claimed that egg-collecting was not just a hobby but a science, going by the name of oology, and seeking to establish oology as a recognised sub-discipline of ornithology, these collectors or oologists established formal institutions such as associations and societies, attended meetings where they exhibited unusual finds, and also contributed to specialist publications dedicated to oology. Egg-collecting was therefore many things at once: a culture of the British countryside, from where many eggs were taken; a culture of natural history, taking on the trappings of a science; and a culture of enthusiasm, providing a consuming passion for many collectors. By the early twentieth century, however, opposing voices were increasingly being raised, by conservation groups and other observers, about the impact that egg-collecting was having on bird populations and on the welfare of individual birds. By mid-century the tide had turned against the collectors, and egg-collecting in Britain was largely outlawed in 1954, with further restrictions imposed in 1981. While many egg collections have been lost or destroyed, some have been donated to museums, including Glasgow Museums (GM), which holds in its collections over 30,000 eggs. As a Collaborative Doctoral Award involving the University of Glasgow and GM, the project outlined in this thesis aims to bring to light and to life these egg collections, the activities of the collectors who originally built them, and the wider world of British egg-collecting. By researching archival material held by Glasgow Museums, published specialist egg-collecting journals and other published sources, as well as the eggs as a material archive, this thesis seeks to recover some of the practices and preoccupations of egg collectors. It also recounts the practical activities carried out during the course of the project at GM, particularly those involving a collection of eggs newly donated to the museum during the course of this project, culminating in a new temporary display of birds’ eggs at Glasgow Museums Resource Centre.

Sběratelství v českých zemích a jeho významní představitelé v Českých Budějovicích v 19. a 1. polovině 20. století / Collecting in the Czech lands and its prominent leaders in Ceske Budejovice in the 19th and the first half of the 20th century

DOŠKÁŘOVÁ, Adéla January 2015 (has links)
The thesis focuses on extending collecting activities across the Czech lands and the associated founding of the first institutions of museum and gallery character. The first part deals with Společnost vlasteneckých přátel umění (The Society of Patriotic Friends of Art) and its founders and supporters, which is followed by a chapter concerning collectors and patrons in Bohemia and Moravia in the 19th and early 20th centuries. The second part of the thesis deals with the area of South Bohemia, České Budějovice in particular, with one chapter devoted to the South Bohemian Museum. The author mainly focuses on the origins, history and significant personalities associated with its operation. The subsequent sections deal with two major natives of Ceske Budejovice and its surroundings, an industrialist Vojtech Lanna, later acting in Prague, and a businessman and a politician August Zátka, who, thanks to his social activities played an important role in the early days of collecting and patronal activities of the Zátka family.
