Influences of wood-crafting on technological development in Middle to Late Bronze Age Southern EnglandLee, Robert William January 2014 (has links)
This study explores the relationship between wood-crafting activity and technological development in metal tools during the Late-Middle and Late Bronze Age in Southern England. It suggests that a number of tool types and forms can be characterised as direct responses to specific crafting processes. The study further suggests that through analysis of those tools and crafting processes, the socio-technological relationships between craftspeople and materials can be better explored. The thesis makes a case for the importance of wood-use during the British Bronze Age as a material key both to a range of craft activities and technological change. The discussion highlights the lack of a cohesive analysis of its use, potential and material relationships. It suggests that a semantic approach to craft practice can inform as to how those practices were facilitated, and that particular craft processes focussed on wood-use are manifested in surviving tools. Four tool types are examined - socketed axes, gouges, chisels and saws; their morphology and structure are analysed to discern variations in function and structural trends which are suggestive of common approaches to production and use. The results of this analysis are linked to woodcrafting practices to highlight how particular forms of each tool type were targeted to activity. The study concludes by arguing that Bronze Age tool forms, and their production, were the result of a complex network of social, technological and developmental influences. It finds that a number of forms were indeed targeted to specific wood-crafting tasks, and that tools ostensibly produced separately followed common structural trends which derived from those tasks. The study also concludes that certain tool forms such as saws manifest multi-material developmental origins, and that analysis based on crafting functions has the potential to provide a more cohesive perspective of Bronze Age tool development than has previously been developed.

Stuff happens : a material culture approach to textile conservationEastop, Dinah January 2009 (has links)
Textile conservation, defined here as the preservation, investigation and presentation of textiles, is often viewed largely as a technical and aesthetic problem. This research develops an alternative view by understanding objects as being subject to both material and social change. The dynamic aspects of this material and social process is emphasised as ‘stuff happens’. This research proposes, and provides evidence for, a material culture approach to textile conservation, and demonstrates its development and application. An analysis of case studies shows how the material and the social interact at the point of assessment and intervention. Examination of the material aspects of textile conservation reveals that social values influence decision-making. Values held at the time of conservation are shown to depend on the categories used. Investigation of these categories demonstrates that any anomalous quality of the textile undergoing conservation allows for contestation of social values. As values change over time, analysis of each conservation assessment and intervention reveals a comparison of values held at different times viewed retrospectively. The resulting approach is centred on the interaction between things, persons and language where each mediates relations of the others. It is argued that this material culture approach enhances understanding of the dynamic material and social environment of textile conservation principles and practices.

Strategies for economically sustainable resist dyeing industries in Abeokuta, Ogun State, NigeriaAmebode, Adetoun Adedotun January 2009 (has links)
Nigerian textile and clothing industries is face with crisis under the pressure of influx of smuggled second-hand clothing and cheap and poor quality of Chinese textiles. The situation has resulted to closure of many textile industries and massive unemployment with inability of the few existing industries to compete favourably base on price. The study was carried out in Abeokuta among tie-dye/batik practitioners and consumers of tie-dye/batik products with the aim to examine the challenges facing the resist dyeing industries. The research method is divided into three: Theoretical- this involves using secondary data from books, journal, newspaper, and the web to gather background information; Statistical- this involves the use of questionnaire to gather primary data. The data collected was analysed using SPSS (Statistical Package for Social Scientist); and Visual- this entails the use of images to establish facts and make judgement on the basis of the facts discovered. The findings revealed that the challenges facing the practitioners are multi-facet ranging from poor educational status, lack of adequate training/re-training programmes, poor financial status, low customers’ patronage, poor management and marketing skill, lack of adequate and functional social amenities, low purchasing power of consumers who often buy on credit and pay on instalment (some don’t bother to pay their debt), increased competition from smugglers of second-hand clothing and imported Chinese textiles, poor/ no knowledge of information technology, low access to international/ overseas markets and minimal willingness to take risk. Consumers of tie-dye/batik are pertinent to the study. The findings from the consumers shows that about half of the consumers interviewed cannot afford to buy clothes monthly while slightly more than half buy clothes on credit and pay on instalment. The industry has being affected with change in taste of consumers, consequently one third of the consumers do not patronise tie-dye/batik fabrics. Consumers pointed out that tie-dye/batik fabrics are not colourfast and the designs are too common (frequently seen). Consumers also complained of poor customers services of the practitioners. Base on the findings, the study proposes holistic approach to the challenges. A sustainable model of five major pillars (Continuous innovation, Customer Relationship Management, Government Policy Support, Networking and Practitioners Personal Capacity Development) is proposed. Absence of any of the pillar will result to sustainability collapse of tie-dye/batik industry. Other model being proposed include establishment of an Export Centre with an effective and efficient two way communication model; EVIPI an acronym of English words to stimulate innovative entrepreneurial drive in niche marketing, a model for internal secondhand clothing to revisit the pass me down clothing culture among the Yoruba and a networking model to complement each other for development.

Laget före jaget - de stora sporternas dominans hos TT : En kvantitativ innehållsanalys av innehållet i TT Nyhetsbyråns sportmaterial / There is no I in team – the dominance of major sports in TT’s reportingHögberg, Viktor, Larsson, Jimmie January 2014 (has links)
The purpose of this study is to show which content that is most common in the Swedish News Agency TT Nyhetsbyrån’s sports coverage. It also shows if the coverage is concentrated to for example any special sports, clubs, people or topics. This study uses a quantitative content analysis and the result is based on texts from 28 systematically selected days during one year. In total, the study includes 906 texts. The result of this study shows that the sports content of TT Nyhetsbyrån’s news feed is mainly concentrated to two sports, football/soccer and ice hockey. Several studies of other Sports Media show the same result as this study in terms of news content. One of the conclusions is that the sports coverage is focused on athletes and teams at a professional level. Only a few sports, almost entirely practiced by men, is represented in the reporting. There are also other attributes that seem important for the news coverage. One of the most common attributes is that a big part of the news texts includes Swedish Athletes. Another important attribute is that the news can be related to a country that is close to Sweden in culture.

Cost-Effective, Focused Instrumentation for TT&C/COMMS EngineeringWilliams, Steve 10 1900 (has links)
ITC/USA 2008 Conference Proceedings / The Forty-Fourth Annual International Telemetering Conference and Technical Exhibition / October 27-30, 2008 / Town and Country Resort & Convention Center, San Diego, California / The need for sophisticated tools in the expanding areas of Telemetry, Tracking and Control/Command (TT&C) and Communications (COMMS) system simulation, development, verification, analysis, maintenance, debug, and education is well understood. Emerging requirements for these toolsets include features, ease-of-use, performance, and price points that specifically address telemetry and signals work. And, while not yet as available, understood, or pervasively installed, these economical and focused tools are displacing high-cost, general-purpose Test and Measurement (T&M) equipment at an increasing rate.
