Texts "Con and Pro" : The Early Modern Medical Controversy over Tobacco

The habit of "drinking smoke" , meaning tobacco smoking, caused a true controversy in early modern England. The new substance was used both for its alleged therapeutic properties as well as its narcotic effects. The dispute over tobacco continues the line of written controversies which were an important means of communication in the sixteenth and seventeenth century Europe. The tobacco controversy is special among medical controversies because the recreational use of tobacco soon spread and outweighed its medicinal use, ultimately causing a social and cultural crisis in England. This study examines how language is used in polemic discourse and argumentation. The material consists of medical texts arguing for and against tobacco in early modern England. The texts were compiled into an electronic corpus of tobacco texts (1577 1670) representing different genres and styles of writing. With the help of the corpus, the tobacco controversy is described and analyzed in the context of early modern medicine. A variety of methods suitable for the study of conflict discourse were used to assess internal and external text variation. The linguistic features examined include personal pronouns, intertextuality, structural components, and statistically derived keywords. A common thread in the work is persuasive language use manifested, for example, in the form of emotive adjectives and the generic use of pronouns; the latter is especially pronounced in the dichotomy between us and them. Controversies have not been studied in this manner before but the methods applied have supplemented each other and proven their suitability in the study of conflictive discourse. These methods can also be applied to present-day materials.

Publishing for the Masses : Early Modern English Witchcraft Pamphlets

This study is a pragmatic description of the evolution of the genre of English witchcraft pamphlets from the mid-sixteenth century to the end of the seventeenth century. Witchcraft pamphlets were produced for a new kind of readership semi-literate, uneducated masses and the central hypothesis of this study is that publishing for the masses entailed rethinking the ways of writing and printing texts. Analysis of the use of typographical variation and illustrations indicates how printers and publishers catered to the tastes and expectations of this new audience. Analysis of the language of witchcraft pamphlets shows how pamphlet writers took into account the new readership by transforming formal written source materials trial proceedings into more immediate ways of writing. The material for this study comes from the Corpus of Early Modern English Witchcraft Pamphlets, which has been compiled by the author. The multidisciplinary analysis incorporates both visual and linguistic aspects of the texts, with methodologies and theoretical insights adopted eclectically from historical pragmatics, genre studies, book history, corpus linguistics, systemic functional linguistics and cognitive psychology. The findings are anchored in the socio-historical context of early modern publishing, reading, literacy and witchcraft beliefs. The study shows not only how consideration of a new audience by both authors and printers influenced the development of a genre, but also the value of combining visual and linguistic features in pragmatic analyses of texts.

Finlandssvenska åsikter om och attityder till modern språkpåverkan

The study describes and analyzes Finland Swedes attitudes to modern-day linguistic influence, the relationship between informants explicitly reported views and the implicit attitudes they express towards language influence. The methods are primarily sociolinguistic. For the analysis of opinions and attitudes I have further developed and tested a new tool in attitude research. With statistical correlation analysis of data collected through a quantitative survey I describe the views that Swedish-language Finns (N=500) report on the influence of English, on imports, and on domain loss. With experimental matchedguise techniques, I study Finland-Swedes (N=600) subconscious reactions to English imports in spoken text. My results show that the subconscious reactions in some respects differ markedly from the views informants explicitly report that they have: informants respond that they would like English words that come into Swedish to be replaced by Swedish replacement words, but in a matched-guise test on their subconscious attitudes, the informants consider English words in a Swedish context to have a positive effect. The topic is further dealt with in interviews where I examine 36 informants implicit attitudes through interactional sociolinguistic analyses. This study comes close to pragmatic discourse analysis in its focus on pragmatic particles and modality. The study makes a rather strict distinction between explicitly expressed opinions and implicit, subconscious attitudes. The quantitative analyses suggest that the opinions we express can be tied to the explicit in language. The outcome of the matched-guise test shows that it is furthermore possible to find subconscious, implicit attitudes that people in actual situations rely on when they make decisions. The discourse analysis finds many subconscious signals, but it also shows that the signals arise in interaction with one s interlocutor, the situation, and the norms in the society. To account for this I have introduced the concept of socioconscious attitude. Socioconscious attitudes reflect not only the traditions and values the utterer grew up with, but also the speaker s relation to the social situation (s)he takes part in.

Single Particle and Packed Bed Combustion in Modern Gasifier Stoves—Density Effects

This article is concerned with a study of an unusual effect due to density of biomass pellets in modern stoves based on close-coupled gasification-combustion process. The two processes, namely, flaming with volatiles and glowing of the char show different effects. The mass flux of the fuel bears a constant ratio with the air flow rate of gasification during the flaming process and is independent of particle density; char glowing process shows a distinct effect of density. The bed temperatures also have similar features: during flaming, they are identical, but distinct in the char burn (gasification) regime. For the cases, wood char and pellet char, the densities are 350, 990 kg/m(3), and the burn rates are 2.5 and 3.5 g/min with the bed temperatures being 1380 and 1502 K, respectively. A number of experiments on practical stoves showed wood char combustion rates of 2.5 +/- 0.5 g/min and pellet char burn rates of 3.5 +/- 0.5 g/min. In pursuit of the resolution of the differences, experimental data on single particle combustion for forced convection and ambient temperatures effects have been obtained. Single particle char combustion rate with air show a near-d(2) law and surface and core temperatures are identical for both wood and pellet char. A model based on diffusion controlled heat release-radiation-convection balance is set up. Explanation of the observed results needs to include the ash build-up over the char. This model is then used to explain observed behavior in the packed bed; the different packing densities of the biomass chars leading to different heat release rates per unit bed volume are deduced as the cause of the differences in burn rate and bed temperatures.

Modern energy access to all in rural India: An integrated implementation strategy

Expanding energy access to the rural population of India presents a critical challenge for its government. The presence of 364 million people without access to electricity and 726 million who rely on biomass for cooking indicate both the failure of past policies and programs, and the need for a radical redesign of the current system. We propose an integrated implementation framework with recommendations for adopting business principles with innovative institutional, regulatory, financing and delivery mechanisms. The framework entails establishment of rural energy access authorities and energy access funds, both at the national and regional levels, to be empowered with enabling regulatory policies, capital resources and the support of multi-stakeholder partnership. These institutions are expected to design, lead, manage and monitor the rural energy interventions. At the other end, trained entrepreneurs would be expected to establish bioenergy-based micro-enterprises that will produce and distribute energy carriers to rural households at an affordable cost. The ESCOs will function as intermediaries between these enterprises and the international carbon market both in aggregating carbon credits and in trading them under CDM. If implemented, such a program could address the challenges of rural energy empowerment by creating access to modern energy carriers and climate change mitigation. (C) 2011 Elsevier Ltd.
