Energieffektivisering av klimatskal med hänsyn till kulturhistorisk värdering : Fallstudier av tre befintliga småhus från 1900-talet ur bevarandesynpunkt

Allt hårdare lagkrav gör att det är svårt att energieffektivisera befintliga byggnader utan att förändra deras utseende. Syftet med examensarbetet är att utreda hur stor energieffektivisering, för tre befintliga småhus uppförda under 1900-talet, som är möjlig att uppnå genom förbättring av byggnadernas klimatskal, det vill säga tak, väggar, golv, fönster och dörrar, utan att förvanska byggnadernas utseende och samtidigt bevara deras kulturhistoriska värden. Arbetet bestod av en förstudie där tre byggnader identifierades, ett undersökningsskede där information om byggnaderna togs fram och ett slutsatsskede där energibesparande åtgärdsförslag togs fram och utvärderades. Byggnader som var goda representanter för sin tid och stil söktes. Byggnader från 1910-talet, 1930-talet och 1970-talet, lokaliserades. Sedan gjordes det fallstudier med intervjuer och inventeringar. För att utreda byggnadens klimatskal utfördes u-värdesberäkningar och energiberäkningar av befintliga byggander och byggnader baserade på föreslagna åtgärdsförslag. Ingen av byggnaderna nådde efter föreslagna åtgärder ner till passivhuskravet 59 kWh/år/m2 Atemp eller BBR-kravet 110 kWh/år/m2 Atemp för en byggnads specifika energianvändning. Den största möjliga energieffektivisering för de tre byggnaderna uppförda under 1900-talet, som är möjlig att uppnå utan att förvanska byggnadernas utseende och samtidigt bevara deras kulturhistoriska värden är 13,0 kWh/år/m2 Atemp, 49,7 kWh/år/m2 Atemp respektive 64,8 kWh/år/m2 Atemp. Slutsatser från arbetet är att byggnader från 1910-tal kan åtgärdas genom att isolera fönstren, sätta dit en extra dörr på insidan av ytterdörren samt tilläggsisolera snedtaket. Byggnader från 1930-tal kan åtgärdas genom att isolera fönstren med en isolerruta på insidan av fönstret och dörrarna med en extra dörr på insidan av ytterdörren. Byggnader från 1970-tal kan åtgärda fönstren genom att byta ut dem till energifönster, ingen åtgärd för golvet men fasaden isoleras utvändigt med vakuumisolering. Byggnaden från 1970-talet klarade sig bäst i jämförelsen eftersom den var i autentiskt skick från början vilket gjorde att förbättringen blev större än för till exempel byggnaden från 1910-talet som redan var ombyggd innan åtgärder föreslogs.

"Äfven jag har en historia!" : En undersökning av den kulturellt bildade diskursen kring folkmusik under sekelskiftet 1800-1900

I denna uppsats undersöks folkmusikens symbolfunktion för upprätthållandet av 1800-1900-talens kollektiva nationalidentitet. Detta görs genom en analys av den språkliga framställningen av folkmusik inom kulturellt bildade kretsar. Uppsatsen behandlar det skriftliga språket som en reflektion av en skribents värderingar och allmänna världsbild. Genom att analysera den språkliga framställningen av folkmusik med ett teoretiskt underlag att applicera som samhällelig kontext söker uppsatsen att besvara frågeställningar kring värderingen av folkmusik, dess förekomst i vardagen, och dess symboliska funktion inom en avgränsad diskurs. Analysen resulterar i besvarade frågeställningar som stämmer väl in på det teoretiska underlaget som uppsatsen baseras på.

Maine and the Hartford Convention: The Impact of the War of 1812 on the Politics of Maine and Massachusetts

The question of why the New England Federalists failed to force a confrontation with the national government has been a continuing historical controversy. I feel that the vigorous stance of the New England Democratic-Republicans particularly in Maine (then a part of Massachusetts), to radical Federalist schemes acted to restrain their opponents. In the final analysis my argument is that New England could not act without Maine. To paraphrase Federalist George Herbert of Ellsworth, on such a slender thread do the destinies of nations hang.

Letting go without a fight : decolonization, democracy and war, 1900-94

Does the type of regime really make no difference to the likelihood of violent conflict over basic issues of stateness such as separatism and decolonization? Can democratic peace theory be successfully applied when dealing with the national identity or stateness question? This article extends the application of the democratic peace to the process of decolonization. It examines conflict between imperial states and their colonies during the process of decolonization and investigates the question of whether democracy affects the likelihood of conflict. The central finding is that, contrary to the implications of some prominent theories of state formation and democracy, democratic imperial states are significantly less likely to go to war with their colonial possessions in the process of achieving independence. Further, the authors find only a monadic, not dyadic, democratic peace effect. The regime type of the colony does not have a significant effect on the likelihood of war. It is the nature of the regime of imperial states, rather than that of colonies, that is a significant factor. In addition, the predominant source of this effect appears to be the institutional constraints placed on executive action within democracies, rather than the influence of mass politics or the effects of political competition. Regarding power-related factors, power parity between sovereign and colony makes conflict more likely (a colonial power-transition effect), but imperial decline actually makes war with colonies less likely. Sensitivity analysis reveals that a number of other hypothesized effects cannot find robust support. Simulations are used to assess the magnitude of the effect of regime type pre- and post-independence. Overall, the article contributes to theory development by investigating different institutional aspects of democracy and by distinguishing monadic and dyadic effects.

"Our fingers were never idle" : women and domestic craft in the Geelong region, 1900-1960

This thesis is an exploration of women's domestic crafts in the Geelong region, between 1900 and I960, Through analysing oral testimony and the women's handicraft artefacts, the nature of the domestic production of handicrafts and the meanings the makers have constructed around their creations and their lives is illuminated. The thesis is organised around the themes of work, space, the construction of femininity, memory, time and meaning. The thesis argues that until recently, the discipline of history has privileged the experiences of men over those of women. It challenges the trivialising of women’s handicrafts. It also argues that within the restrictive social structures around them and within the confined nature of their situations, the women of my study asserted themselves to transform their environments and to improve their situations through labour in the home. In ‘making do’, recycling materials and creating functional and decorative needlework items for their homes and families, the women were often finding solutions to pressing practical and economic problems. Doing handicrafts was rarely just a passive way of filling in time. Rather, making and creating was for these women a multi-layered activity that similtaneously fulfilled a complex range of needs for themselves and their families. A multiplicity of deeply personal, aesthetic, familial, social, practical and economic needs were met in the making of domestic craft artefacts, whose symbolism reflected the values and meanings of the women's cultures, homes and families.

Public libraries in Ballarat : 1851-1900

This thesis analyses the development of the Ballarat East Free Library (1859), the Ballarat Mechanics’ Institute Library (1859) and the City of Ballaarat Free Library (1878) within the broader context of public librarianship in Victoria between 1851-1900. Mechanics’ Institute libraries and free libraries represent the major derivatives of a nineteenth-century library model that emphasised the pursuit of lifelong learning, private reading and the enjoyment of genteel recreational facilities. The circumstances that led to the formation of an Institute and a free library in Ballarat in, 1,859 provide a unique opportunity to analyse the public library model for two reasons. These libraries were established in a remarkable goldfield city that enjoyed a number of economic and cultural advantages and secondly, the Ballarat Mechanics’ Institute Library and the Ballarat East Free Library experienced such spectacular growth that by 1880 they were two of the largest public libraries in Australia. However, it is argued that this growth cycle could not be sustained due to a combination of factors including low membership levels, limited funding for recurrent expenditure purposes, and heightened dissatisfaction with the book collections. Libraries began to stagnate in the late-1880s and the magnitude of this collapse in Ballarat, and throughout the colony, was subsequently confirmed with the publication of a national survey of Australian libraries in 1935. The ‘Munn-Pitt’ report found that public libraries had provided a better service in 1880 than at any other time in the next six decades. Four conclusions are drawn in this comparative analysis of the Ballarat Mechanics’ Institute Library, the Ballarat East Free Library, and to a lesser extent, the City of Ballaarat Free Library, between 1851-1900. Firstly, is it shown that the literature places considerable emphasis on the formation of public libraries but is far less critical of the long-term viability of the public library model as it evolved in Ballarat and throughout the colony in the nineteenth century. Secondly, whilst Ballarat and its library committees benefited from the city's prosperity and the entrepreneurial zeal of its pioneers, these same library committees were unable to overcome the structural flaws in the public library model or to dispel the widespread belief that libraries were elitist organisations. As a consequence, membership of the major libraries in Ballarat never exceeded 4% of the total population. Thirdly, it is acknowledged that an absence of records relating to book borrowing habits by individuals limits is a limiting factor, but this problem has been addressed, in part, by undertaking a comparative analysis of collection development policies, invoices, lists of popular authors and books, public comment and the book borrowing patterns of a number of comparable libraries in central Victoria. These resources provide a number of insights into the reading habits of library patrons in Ballarat in the late-nineteenth century. Finally, this thesis focuses on the management policies and practices of each library committee in Ballarat in order to move beyond the traditional explanation for the demise of nineteenth-century libraries and to propose an alternative explanation for the stagnation of public libraries in Ballarat in the mid-1880s. The traditional explanation for the demise of colonial libraries was the sudden reduction in government funding in the 1890s, whereas this thesis argues that a combination of factors, including the unresolved tensions with regard to libraries collection development policies, committee and municipal rivalry, and increasing conservatism, had already damaged the credibility of Ballarat’s libraries by the mid-1880s. It is argued that the intense rivalry between library committees resulted in an unnecessary duplication of services and an inadequate membership base. It is also argued that the increasingly conservative, un-cooperative and uninviting attitudes of these library committees discouraged patronage and as a direct consequence, membership and daily visitor rates of the free and Institute libraries in Ballarat plummeted by 80% between 1880-1900.

The story of Australian agricultural economics 1900-1975

The growth of the agricultural economics profession in Australia is evaluated within the context of government policy. Particular economists and agricultural economists were instrumental in questioning the government's policy approach to agriculture. Their life work is assessed to ascertain their legacy to this country through their research, teaching and writing.
