Developing Peer-To-Peer Web Applications

As the virtual world grows more complex, finding a standard way for storing data becomes increasingly important. Ideally, each data item would be brought into the computer system only once. References for data items need to be cryptographically verifiable, so the data can maintain its identity while being passed around. This way there will be only one copy of the users family photo album, while the user can use multiple tools to show or manipulate the album. Copies of users data could be stored on some of his family members computer, some of his computers, but also at some online services which he uses. When all actors operate over one replicated copy of the data, the system automatically avoids a single point of failure. Thus the data will not disappear with one computer breaking, or one service provider going out of business. One shared copy also makes it possible to delete a piece of data from all systems at once, on users request. In our research we tried to find a model that would make data manageable to users, and make it possible to have the same data stored at various locations. We studied three systems, Persona, Freenet, and GNUnet, that suggest different models for protecting user data. The main application areas of the systems studied include securing online social networks, providing anonymous web, and preventing censorship in file-sharing. Each of the systems studied store user data on machines belonging to third parties. The systems differ in measures they take to protect their users from data loss, forged information, censorship, and being monitored. All of the systems use cryptography to secure names used for the content, and to protect the data from outsiders. Based on the gained knowledge, we built a prototype platform called Peerscape, which stores user data in a synchronized, protected database. Data items themselves are protected with cryptography against forgery, but not encrypted as the focus has been disseminating the data directly among family and friends instead of letting third parties store the information. We turned the synchronizing database into peer-to-peer web by revealing its contents through an integrated http server. The REST-like http API supports development of applications in javascript. To evaluate the platform s suitability for application development we wrote some simple applications, including a public chat room, bittorrent site, and a flower growing game. During our early tests we came to the conclusion that using the platform for simple applications works well. As web standards develop further, writing applications for the platform should become easier. Any system this complex will have its problems, and we are not expecting our platform to replace the existing web, but are fairly impressed with the results and consider our work important from the perspective of managing user data.

Zur lexikographischen Darstellung der Adjektivsyntax in neueren einsprachigen Wörtbüchern des Deutschen

The main objects of the investigation were the syntactic functions of adjectives. The reason for the interest in these functions are the different modes of use, in which an adjective can occur. All together an adjective can take three different modes of use: attributive (e. g. a fast car), predicative (e. g. the car is fast) and adverbial (e. g. the car drives fast). Since an adjective cannot always take every function, some dictionaries (esp. learner s dictionaries) deliver information within the lexical entry about any restrictions. The purpose of the research consisted of a comparison in relation to the lexical entries of adjectives, which were investigated within four selected monolingual German-speaking dictionaries. The comparison of the syntactical data of adjectives were done to work out the differences and the common characteristics of the lexical entries concerning the different modes of use and to analyse respective to assess them. In the foreground, however, were the differences of the syntactical information. Concerning those differences it had to be worked out, which entry is the grammatically right one respective if one entry is in fact wrong. To find that out an empirical analysis was needed, which based on the question in which way an adjective is used within a context as far as there are no conforming data within the dictionaries. The delivery of the correctness and the homogeneity of lexical entries of German-speaking dictionaries are very important to support people who are learning the German language and to ensure the user friendliness of dictionaries. Throughout the investigations it became clear that in almost half of the cases (over 40 %) syntactical information of adjectives differ from each other within the dictionaries. These differences make it for non-native speakers of course very difficult to understand the correct usage of an adjective. Thus the main aim of the doctoral thesis was it to deliver and to demonstrate the clear syntactical usage of a certain amount of adjectives.

Struggles over legitimacy in global organizational restructuring: A rhetorical perspective on legitimation strategies and dynamics in a shutdown case

Critical organization scholars have focused increasing attention on industrial and organizational restructurings such as shutdown decisions. However, we know little about the rhetorical strategies used to legitimate or resist plant closures in organizational negotiations. In this paper, we draw from New Rhetoric to analyze rhetorical struggles, strategies and dynamics in unfolding organizational negotiations. We focus on the shutdown of the bus body unit of the Swedish company Volvo in Finland. We distinguish five types of rhetorical legitimation strategies and dynamics. These include the three classical dynamics of logos (rational arguments), pathos (emotional moral arguments), and ethos (authority-based arguments), but also autopoiesis (autopoietic narratives), and cosmos (cosmological constructions). Our analysis adds to the previous studies explaining how organizational restructuring as a phenomenon is legitimated, how this legitimation has changed over time, and how contemporary industrial closures are legitimated in the media. This study also increases our theoretical understanding of the role of rhetoric in legitimation more generally.

Struggling over subjectivity: A discursive analysis of strategic development in a group

We have seen growing interest in discursive perspectives on strategy. This perspective holds great promise for development of an understanding on how strategy discourse and subjectivity are intertwined. We wish to add to this existing research by outlining a discursive struggle approach to subjectivity. To understand the complex subjectification and empowering/disempowering effects of organizational strategy discourse, this approach focuses on organization-specific discourse mobilizations an various ways of resistance. Drawing on an analysis of the discourses and practices of ‘strategic development’ in an engineering and consulting group we provide an empirical illustration of such struggles over subjectivity. In particular, we report three examples of competing ways of making sense of and giving sense to strategic development, with specific subjectification tendencies. First, we show how corporate management can mobilize and appropriate a specific kind of discourse to attempt to gain control of the organization, which tends to reproduce managerial hegemony, but also trigger discursive and other forms of resistance. Second, we will illustrate how middle managers resist this hegemony by initiating a strategy discourse of their own to create room for manoeuvre in controversial situations. Third, we show how project engineers can distance themselves from managerial-initiated strategy discourses to maintain a viable identity despite all kinds of pressures. Although our examples are case-specific, we believe that similar discursive dynamics also characterize strategizing in other organizations.

A Story about a Message that was a Story: Message Form and its Implications to Knowledge Flow

Knowledge Flow, my dear friend! I would like to introduce you to a close relative of yours: Organizational Communication. You might want to take a moment to hear what your newfound kin has to say. As bright as you are dear Flow, you're missing a piece of the puzzle - for one cannot study any aspect of an organization relating to communication without acknowledging the message. Without a message, communication does not exist. Organizational Communication has always appreciated this. Perhaps the time has come for you to join rank and do so too? The main point of this work is to prove that the form of a message considerably affects communication, interpretation - and knowledge flow. As stories are at the heart of this thesis; and entertaining, reader-friendly communication its main argument, the entire manuscript is written in story form and is intentionally breaking academic writing tradition as far as writing style goes. Each chapter reads as a story of sorts and put together they create a grand narrative of my journey as a PhD student, the research I have conducted and the outcomes of this work. Thus if a reader hopes to make any sense of this title, she must read it in the same way one would read a novel, from beginning to end. This is a thesis with three aspirations. First, it sets out to prove that knowledge flow cannot be studied without a message. Second, it moves on to give the reader a once-over of a much used message form: storytelling. After these two goals are tackled the path is clear to research if message form indeed is as essential as claimed. I do so through both a qualitative and a quantitative study. The former acted as both a stepping stone into the research area and as an inspirational pilot, from which the research design for the larger quantitative study was drawn. Together, these two studies answered my research question - and allowed me to fulfill the third, final and foremost aspiration of this study - bridging the gap between two separate fields of knowledge management: knowledge flow and storytelling.

Towards a Conceptual History of Narrative

The article outlines a conceptual history of narrative, in particular the changes over the movement called “narrative turn” in the social sciences. According to Quentin Skinner, conceptual changes may take place on three separate levels: by changing the criteria of the concept, by changing the range of reference, and by changing the appraisal of the concept. Recent theorizing on narrative epitomizes all of these levels, but unevenly. In spite of the rhetoric of interdisciplinarity, two almost totally separate traditions of narrative theory persist: the narratological and the narrative-turn theories. Paradoxically, the narrative turn literature has radicalized the range of reference of narrative by attaching the concept to life and identity, but has left the criteria of the concept practically intact. This has extended the reign of a simplified Aristotelian concept of narrative as a chain of beginnings, middles, and ends. The narratological tradition of theorizing, instead, has debated extensively on the correct criteria of the concept, but enlarged the range of reference rather in the direction of cognition.

Struggles Over Legitimacy in Global Organizational Restructuring: A Rhetorical Perspective on Legitimation Strategies and Dynamics in a Shutdown Case

Critical organization scholars have focused increasing attention on industrial and organizational restructurings such as shutdown decisions. However, little is known about the rhetorical strategies used to legitimate or resist plant closures in organizational negotiations. In this article, we draw from New Rhetoric to analyze rhetorical struggles, strategies and dynamics in unfolding organizational negotiations. We focus on the shutdown of the bus body unit of the Sweden-based Volvo Bus Corporation in Finland. We distinguish five types of rhetorical legitimation strategies and dynamics. These include the three classical dynamics of logos (rational arguments), pathos (emotional moral arguments), and ethos (authority-based arguments), but also autopoiesis (autopoietic narratives), and cosmos (cosmological constructions). Our analysis contributes to previous studies on organizational restructuring by providing a more nuanced understanding of how contemporary industrial closures are legitimated and resisted in organizational negotiations. This study also increases theoretical understanding of the role of rhetoric in legitimation more generally.

On formation, growth and concentrations of air ions

Aerosol particles have effect on climate, visibility, air quality and human health. However, the strength of which aerosol particles affect our everyday life is not well described or entirely understood. Therefore, investigations of different processes and phenomena including e.g. primary particle sources, initial steps of secondary particle formation and growth, significance of charged particles in particle formation, as well as redistribution mechanisms in the atmosphere are required. In this work sources, sinks and concentrations of air ions (charged molecules, cluster and particles) were investigated directly by measuring air molecule ionising components (i.e. radon activity concentrations and external radiation dose rates) and charged particle size distributions, as well as based on literature review. The obtained results gave comprehensive and valuable picture of the spatial and temporal variation of the air ion sources, sinks and concentrations to use as input parameters in local and global scale climate models. Newly developed air ion spectrometers (Airel Ltd.) offered a possibility to investigate atmospheric (charged) particle formation and growth at sub-3 nm sizes. Therefore, new visual classification schemes for charged particle formation events were developed, and a newly developed particle growth rate method was tested with over one year dataset. These data analysis methods have been widely utilised by other researchers since introducing them. This thesis resulted interesting characteristics of atmospheric particle formation and growth: e.g. particle growth may sometimes be suppressed before detection limit (~ 3 nm) of traditional aerosol instruments, particle formation may take place during daytime as well as in the evening, growth rates of sub-3 nm particles were quite constant throughout the year while growth rates of larger particles (3-20 nm in diameter) were higher during summer compared to winter. These observations were thought to be a consequence of availability of condensing vapours. The observations of this thesis offered new understanding of the particle formation in the atmosphere. However, the role of ions in particle formation, which is not well understood with current knowledge, requires further research in future.

Lyophilized disaccharides – the effect of water during storage

Nearly one fourth of new medicinal molecules are biopharmaceutical (protein, antibody or nucleic acid derivative) based. However, the administration of these compounds is not always that straightforward due to the fragile nature of aforementioned domains in GI-tract. In addition, these molecules often exhibit poor bioavailability when administered orally. As a result, parenteral administration is commonly preferred. In addition, shelf-life of these molecules in aqueous environments is poor, unless stored in low temperatures. Another approach is to bring these molecules to anhydrous form via lyophilization resulting in enhanced stability during storage. Proteins cannot most commonly be freeze dried by themselves so some kind of excipients are nearly always necessary. Disaccharides are commonly utilized excipients in freeze-dried formulations since they provide a rigid glassy matrix to maintain the native conformation of the protein domain. They also act as "sink"-agents, which basically mean that they can absorb some moisture from the environment and still help to protect the API itself to retain its activity and therefore offer a way to robust formulation. The aim of the present study was to investigate how four amorphous disaccharides (cellobiose, melibiose, sucrose and trehalose) behave when they are brought to different relative humidity levels. At first, solutions of each disaccharide were prepared, filled into scintillation vials and freeze dried. Initial information on how the moisture induced transformations take place, the lyophilized amorphous disaccharide cakes were placed in vacuum desiccators containing different relative humidity levels for defined period, after which selected analyzing methods were utilized to further examine the occurred transformations. Affinity to crystallization, water sorption of the disaccharides, the effect of moisture on glass transition and crystallization temperature were studied. In addition FT-IR microscopy was utilized to map the moisture distribution on a piece of lyophilized cake. Observations made during the experiments backed up the data mentioned in a previous study: melibiose and trehalose were shown to be superior over sucrose and cellobiose what comes to the ability to withstand elevated humidity and temperature, and to avoid crystallization with pharmaceutically relevant moisture contents. The difference was made evident with every utilized analyzing method. In addition, melibiose showed interesting anomalies during DVS runs, which were absent with other amorphous disaccharides. Particularly fascinating was the observation made with polarized light microscope, which revealed a possible small-scale crystallization that cannot be observed with XRPD. As a result, a suggestion can safely be made that a robust formulation is most likely obtained by utilizing either melibiose or trehalose as a stabilizing agent for biopharmaceutical freeze-dried formulations. On the other hand, more experiments should be conducted to obtain more accurate information on why these disaccharides have better tolerance for elevating humidities than others.

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.

Jakojuuriviljelyn vaikutus kasvihuonekurkun (Cucumis sativus L.) kasvuun ja kehitykseen

Kasvit ottavat vettä parhaiten kasteluravinneliuoksesta, jonka ravinnepitoisuus on pieni. Intensiivisessä kasvihuonetuotannossa käytetään silti kastelulannoituksessa usein korkeita ravinnepitoisuuksia ravinnepuutosten ja satotappioiden välttämiseksi. Jakojuuriviljelyssä kasvin juuriston annetaan kasvaa kahteen erilliseen kasvualustaosioon. Tällöin toiselle puolelle annetaan johtokyvyltään väkevää ja toiselle puolelle laimeaa ravinneliuosta. Erityisesti kasvihuonekurkun, joka on herkkä kasvualustan suolaisuuden aiheuttamille vedensaantiongelmille, on todettu hyötyvän tästä tekniikasta, mikä näkyy kasvaneina satoina. Tämän MTT Piikkiössä toteutetun kasvihuonekurkun jakojuuriviljelytutkimuksen tavoitteena oli tarkentaa tekniikkaa erityisesti kasteluliuosten johtokyvyn osalta. Yhtenäisjuuriviljelyn ja perinteisen jakojuuriviljelyn lisäksi kokeessa oli kaksi jakojuuriviljelykäsittelyä, joissa ravinneliuosväkevyyksiä vaihdettiin väliajoin juuriston toimintakyvyn parantamiseksi. Erillisessä osakokeessa tutkittiin erilaisten johtokyky-yhdistelmien vaikutusta kasvihuonekurkun vegetatiiviseen kasvuun maanpäällisten ja -alaisten kasvinosien välillä sekä juurten morfologiaan ja anatomiaan. Tulokset osoittivat, että jakojuuriviljely lisäsi kasvihuonekurkun sadontuottoa jopa 16 %, mutta ei vaikuttanut koko viljelykauden veden tai ravinteiden ottoon. Yhtenäisjuuriviljelyssä muodostui eniten piikkikärkisiä hedelmiä, mikä viittaa vedensaantiongelmiin haihdutustarpeen ollessa suurin. Viljelytekniikalla ei ollut vaikutusta kasvien vegetatiiviseen kasvuun tai kasvuston rakenteeseen. Lehtiruodeista tehdyt nitraatti- ja kaliummittaukset osoittivat, ettei kasteluliuosten ravinnepitoisuuksilla ollut vaikutusta juurten ravinteiden ottoon. Erilaisilla johtokyky-yhdistelmillä oli huomattavampi vaikutus kasvihuonekurkun juurten painoon kuin verson painoon tai varren pituuskasvuun. Lehtiruotianalyysit viittasivat ravinteiden erilaiseen allokointiin eri johtokyky-yhdistelmissä. Korkeiden johtokykyjen aiheuttama osmoottinen stressi johti muutoksiin juurten morfologiassa ja anatomiassa. Tulosten perusteella jakojuuriviljely paransi kehittyvien hedelmien kohdevahvuutta suhteessa muihin kohteisiin vaikuttamatta vegetatiiviseen kasvuun. Kun laimean ja väkevän ravinneliuoksen puolia vaihdettiin, juuristo otti joustavasti vettä ja ravinteita olosuhteiden määräämästä edullisemmasta johtokyvystä, jolloin kasvihuonekurkun viljelyssä saavutettiin merkittävä satoetu. Juuriston jakaminen vaikuttanee kasvien hormoniaineenvaihduntaan ja voi heikentää juuriston kasvua heikentämättä sen toimintakykyä, jolloin yhteyttämistuotteita kohdennetaan tehokkaammin maanpäällisten osien kasvuun.

Kymmenen teollisesti merkittävän puulajin kuoriuutteiden mahdollisuudet tuholaistorjunnassa

Metsäteollisuudesta kertyy vuosittain suuria määriä ylijäämämateriaalia, kuten puun kuorta ja oksia.Ylimääräinen aines käytetään pääasiassa energiantuotantoon, mutta uusia soveltamismahdollisuuksia kaivataan. Kuoren on havaittu olevan potentiaalinen lähde monille bioaktiivisille yhdisteille, joille olisi käyttöä esimerkiksi lääke- ja kemianteollisuudessa sekä maa-, metsä- ja puutarhatuotannon tuholaistorjunnassa. Tutkimus on osa Euroopan Unionin rahoittamaa ForestSpeCs-projektia, jonka tarkoituksena on selvittää metsäteollisuuden ylijäämämateriaalien vaihtoehtoisia käyttötapoja. Valittujen kymmenen teollisesti merkittävän pohjoisen puulajin (Abies nephrolepis, Betula pendula, Larix decidua, L. gmelinii, L. sibirica, Picea abies, P. ajanensis, P. pumila, Pinus sylvestris, Populus tremula) kuoresta uutettujen aineiden soveltuvuutta syönninestoaineeksi testattiin kaaliperhosen (Pieris brassicae L.) ja krysanteemiyökkösen (Spodoptera littoralis Boisduval) toukilla sekä osittain sinappikuoriaisella (Phaedon cochloreae Fabricius) ja idänlehtikuoriaisella (Agelastica alni L.). Uutteet valmistettiin yhteistyössä projektin ryhmien avulla tai itsenäisesti erilaisin menetelmin. Testaukset tehtiin laboratorio-oloissa käyttäen lehtikiekkojen valintabiotestiä sekä karkeilla uutteilla että niistä erotelluilla yksittäisillä yhdisteillä. Tehdyistä mittauksista laskettiin syönninestoindeksit (FDI). Tulosten perusteella lähes kaikki testatut uutteet vaikuttivat ainakin jossain määrin kohdehyönteisen syöntikäyttäytymiseen. Hieman yli puolet kaaliperhosella testatuista 46 uutteesta aiheuttivat yli 50 % syönnineston eli kaaliperhonen suosi kontrollilehtiä uutteella käsiteltyjä todennäköisemmin. Krysanteemiyökkösellä yli 50 %:n syönnineston aiheuttivat vain seitsemän testatuista 56 uutteesta. Lisäksi kolme uutetta lisäsi käsiteltyjen kiekkojen syöntiä merkittävästi. Idänlehtikuoriaistoukat ja -aikuiset karttoivat erityisesti abietiinihapolla käsiteltyjä lehtiä. Sinappikuoriaisella testatut uutteet toimivat myös lupaavasti. Testattujen puulajien kuoresta on mahdollista uuttaa biologisesti aktiivisia yhdisteitä, mutta tuholaistorjunnan kannalta oikeiden pitoisuuksien ja tehokkaiden uuttomenetelmien löytäminen vaatii jatkotutkimuksia. Kuoren sisältämien yhdisteiden laatu ja määrä vaihtelevat monien tekijöiden, kuten ympäristön ja genetiikan vaikutuksesta. Hyönteisten sietokyky vaihtelee myös paljon lajeittain ja yksilöidenkin välillä on eroja. Uutteista valmistettavia torjunta-aineita olisi kuitenkin mahdollista sisällyttää esimerkiksi integroituun torjuntaan muiden menetelmien rinnalle tulevaisuudessa.

Jatrophanviljely ja maankäyttö Vietnamissa

Biofuels are under discussion all over the world today. There are fears that the farming of biofuel plants hurts food production and weakens the food security of the poor. On the other hand, biofuel production could lessen the green house gas emissions caused by transportation, and it could also spread the profits from fuel markets more evenly between countries. The aim of this thesis is to find out how an oil plant called jatropha curcas L., which is used for biodiesel production, can affect the sustainability of livelihoods in Vietnam from the point of view of land use. Special attention is given to the effects of jatropha farming on food production, land productivity, natural resources of livelihoods and global livelihood. Jatropha belongs to the family Euphorbiaceae, and it grows naturally in tropical and subtropical areas. It can be grown on poor soils, its seeds have high oil content, and it cannot be eaten due to its toxicity. The plant grows naturally in Vietnam, and during the past few years it has also begun to be farmed for making biodiesel. Population growth in Vietnam has slowed down, but the population's standard of living and energy consumption are still rising quickly. An interest in the international biodiesel markets has awoken following Vietnam's opening up to international trade. Jatropha diesel plays a significant part in Vietnam’s clean fuel strategy, and many companies have set up jatropha plantations to produce raw material for biodiesel. Diesel made from jatropha is planned to be used both locally and for export. This thesis uses a theoretical concept of sustainable livelihoods. According to the theory, the resources that people have shape their livelihood possibilities. Farming of jatropha affects the livelihoods of people especially through land use, as land use changes have effects on many of the livelihood resources. In addition to the written sources, the material of the thesis is based on 14 interviews in Vietnam and Finland, and on observation during a field trip to Northern Vietnam in the spring of 2008. The results of the thesis show that jatropha diesel can support the sustainability of livelihoods at different scales if it is produced with deliberation. However, positive results are only possible if decisions are made carefully and more experience is collected. The possibilities of sustainable jatropha farming depend mainly on the previous land use methods and ways of production. Farming of jatropha does not threaten food production in Vietnam if the farming plans are implemented as planned. Jatropha may take some land from cassava, but at the same time, food production can be increased if mixed farming is used on some farms. Plenty of new research information and practical experiences on jatropha farming has to be collected before results of the real sustainability of the farming are ready. Carefully considered continuation and documentation of present and future projects would help to understand the possibilities of jatropha diesel in Vietnam and elsewhere.

Kansan raittiudeksi ja kotien onneksi : Naisten kieltolakimielipiteet ja toiminta kieltolain puolesta ja sitä vastaan 1919 - 1932

It is often maintained that the Prohibition Act (in force from 1 June 1919 to 5 April 1932) still influences both the Finnish alcohol policy and notions about alcohol. This study focuses on the development of women s opinions concerning Prohibition in Finland. What role did the formulation and expression of women s opinions and women's actions play in the final outcome of the Prohibition Act? What do the debate on Prohibition and women s activities for and against the legislation tell us about the status and possibilities of women to exert influence in the Finnish society of the Prohibition era? Women s opinions are particularly interesting since they deviated radically from what has generally been assumed. It was expected that the referendum of 1931 would result in a resounding vote of 100% in favour of Prohibition, but the outcome was a majority vote against it. Over 65% of the women who cast their vote in the referendum wanted a full repeal of Prohibition. The study approaches the history of Prohibition by combining methods and theories of the history of mentalities and social history with gender history. Women are examined as a heterogeneous group with dissimilar objectives and differing ways of acting and thinking. The research material consists of press materials, archival materials from organisations, personal materials and statistics from the Prohibition period. Both discourses and practices are examined; the object of the research is best described by Michel Foucault's concept of dispositif. When participating in the public debate on Prohibition, women based their right to express their opinions and take part in action on an ideological continuum spanning a hundred years, according to which home and family were central areas of women s interest. This idea was linked to questions of morality and social policy. On the other hand, women presented themselves as working taxpayers, voters and equal citizens. The most crucial issue in women's discussions was whether Prohibition improved or worsened the temperance of fathers, husbands and sons. The dichotomies town dweller - countryside dweller, Swedish-speaking Finnish-speaking, and middle class - working class were highly significant backgrounds both as factors dividing women and in public discussions regarding Prohibition. The 1931 referendum showed that the lines of demarcation drawn during the preceding debate did not materialise in political action in line with these dichotomies: the dispositif did not correspond to the discourse. Contrary to what was expressed in public, a great number of women among the labour and rural classes, among inland inhabitants and among Finnish-speakers were also against Prohibition. The media and organisations defended temperance and Prohibition almost until the end of the Prohibition era. This discourse was in conflict with the discourse of everyday conversations and practices in which alcohol was present.
