Blogging

Weblogs, or blogs, constitute a form and genre of online publishing that emerged in the mid-1990s as a logical consequence of the confluence of personal and professional home pages and new web publishing technologies. To overcome technological limitations, where news updates had to be manually inserted by editing the underlying HTML code, the early content-management systems in the second half of the 1990s built on server-side database technology to dynamically generate web pages; this enabled more convenient and more frequent content updates. Weblogs utilised such technologies to provide an up-to-date news feed, presenting individual news items in reverse chronological order. Most blogging platforms provide commenting functions that enable readers to respond to and discuss individual blog posts...

Kirurgisen operaation teatteri : Teatterillinen kuva ja ihmismuodon esitettävyys avantgardistisen väkivallan näkökulmasta

Dissertation considers the birth of modernist and avant-gardist authorship as a reaction against mass society and massculture. Radical avant-gardism is studied as figurative violence done against the human form. The main argument claims avant-gardist authorship to be an act of masculine autogenesis. This act demands human form to be worked to an elementary state of disarticulateness, then to be reformed to the model of the artist's own psychophysical and idiosyncratic vision and experience. This work is connected to concrete mass, mass of pigment, charcoal, film, or flesh. This mass of the figure is worked to create a likeness in the nervous system of the spectator. The act of violence against the human figure is intended to shock the spectator. This shock is also a state of emotional and perceptional massification. I use theatrical image as heuristic tool and performance analysis, connecting figure and spectator into a larger image, which is constituted by relationships of mimesis, where figure presents the likeness of the spectator and spectator the likeness of the figure. Likeness is considered as both gestural - social mimetic - and sensuous - kinesthetically mimetic. Through this kind of construction one can describe and contextualize the process of violent autogenesis using particular images as case studies. Avant-gardist author is the author of theatrical image, not particular figure, and through act of massification the nervous system of the spectator is also part of this image. This is the most radical form and ideology of avant-gardist and modernist authorship or imagerial will to power. I construct a model of gestural-mimic performer to explicate the nature of violence done for human form in specific works, in Mann's novella Death in Venice, in Schiele's and Artaud's selfportaits, in Francis Bacon's paintings, in Beckett's shortplat NOT I, in Orlan's chirurgical performance Operation Omnipresense, in Cindy Sherman's Film/Stills, in Diamanda Galás's recording Vena Cava and in Hitchcock's Psycho. Masspsychology constructed a phobic picture of human form's plasticity and capability to be constituted by influencies coming both inside and outside - childhood, atavistic organic memories, urban field of nervous impulses, unconsciousness, capitalist (image)market and democratic masspolitics. Violence is then antimimetic and antitheatrical, a paradoxical situation, considering that massmedias and massaudiences created an enormous fascination about possibilities of theatrical and hypnotic influence in artistic elites. The problem was how to use theatrical image without coming as author under influence. In this work one possible answer is provided: by destructing the gestural-mimetic performer, by eliminating representations of mimic body techniques from the performer of human (a painted figure, a photographed figure, a filmed figure or an acted figure, audiovisual or vocal) figure. This work I call the chirurgical operation, which also indicates co-option with medical portraitures or medico-cultural diagnoses of human form. Destruction of the autonomy of the performer was a parallel process to constructing the new mass media audience as passive, plastic, feminine. The process created an image of a new kind of autotelic masculine author-hero, freed from human form in its bourgeois, aristocratic, classical and popular versions.

Hallinnon lehdistötiedotteiden kieli

This study seeks to answer the question of what the language of administrative press releases is like, and how and why it has changed over the past few decades. The theoretical basis of the study is provided by critical text analysis, supplemented with, e.g., the metafunction theory of Systemic Functional Grammar, the theory of poetic function, and Finnish research into syntax. The data includes 83 press releases by the City of Helsinki Public Works Department, 14 of which were written between 1979 and 1980 (old press releases), and 69 of which were written between 1998 and 1999 (new press releases). The analysis focuses on the linguistic characteristics of the releases, their changes and variation, their relation to other texts and the extra linguistic context, as well as their genre. The core research method is linguistic text analysis. It is supplemented with an analysis of the communicative environment, based on the authors' interviews and written documents. The results can be applied to the improvement of texts produced by the authorities and even by other organizations. The linguistic analysis focuses on features that transform the texts in the data making them guiding, detailed, and poetic. The releases guide the residents of the city using modal verbal expressions and performative verbs that enable the mass media to publish the guiding expressions on their own behalf as such. The guiding is more persuasive in the new press releases than in the old ones, and the new ones also include imperative clauses and verbless directives that construct direct interaction. The language of the releases is made concrete and structurally detailed by, e.g., concrete vocabulary, proper nouns and terms, as well as definitions, adverbials and comparisons, which are used specifically to present places and administrative organizations in detail. The rhetorical features in the releases include alliteration and metaphors, which are found in the new releases especially in the titles. The emphasized features are used to draw the readers' attention and to highlight the core contents of the texts. The new releases also include words that are colloquial in style, making the communicative situations less official. Structurally, the releases have changed from being letter-like to a more newsflash-like format. The changes in the releases can be explained by the development towards more professional communications and the more market-oriented ideology adopted in the communicative environment. Key words: change in administrative language, press releases, critical text analysis, linguistic text analysis

"Ei vittu, mennään röökille" : tutkimus sitaattien tehtävistä ja tekemisestä kaunokirjallis-journalistisissa lehtijutuissa

This research deals with direct speech quotations in magazine articles through two questions: As my major research question, I study the functions of speech quotations based on a data consisting of six literary-journalistic magazine articles. My minor research question builds on the fact that there is no absolute relation between the sound waves of the spoken language and the graphemes of the written one. Hence, I study the general thoughts on how utterances should be arranged in the written form based on a large review of literature and textbooks on journalistic writing as well as interviews I have made with magazine writers and editors, and the Council of Mass Media in Finland. To support my main research questions, I also examine the reference system of the Finnish language, define the aspects of the literary-journalistic article and study vernacular cues in written speech quotations. FUNCTIONS OF QUOTATIONS. I demonstrate the results of my analysis with a six-pointed apparatus. It is a continuum which extends from the structural level of text, all the way through the explicit functions, to the implicit functions of the quotation. The explicit functions deal with the question of what is the content, whereas the implicit ones base mainly on the question how the content is presented. 1. The speech quotation is an distinctive element in the structure of the magazine article. Thereby it creates a rhythm for the text, such as episodes, paragraphs and clauses. 2. All stories are told through a plot, and in magazine articles, the speech quotations are one of the narrative elements that propel the plot forward. 3. The speech quotations create and intensify the location written in the story. This location can be a physical one but also a social one, in which case it describes the atmosphere and mood in the physical environment and of the story characters. 4. The quotations enhance the plausibility of the facts and assumptions presented in the article, and moreover, when a text is placed between quotation marks, the reader can be assured that the text has been reproduced in the authentic verbatim way. 5. Speech quotations tell about the speaker's unique way of using language and the first-hand experiences of the person quoted. 6. The sixth function of speech quotations is probably the most essential one: the quotations characterize the quoted speaker. In other words, in addition to the propositional content of the utterance, the way in which it has been said transmits a lot of the speaker's character (e.g. nature, generation, behaviour, education, attitudes etc.). It is important to notice, that these six functions of my speech quotation apparatus do not exlude one another. It means that every speech quotation basically includes all of the functions discussed above. However, in practice one or more of them have a principal role, while the others play a subsidiary role. HOW TO MAKE QUOTATIONS? It is not suprising that the field of journalism (textbooks, literature and interviews) holds heterogeneous and unestablished thoughts on how the spoken language should be arranged in written quotations, which is my minor research question. However, the most frequent and distinctive aspects can be depicted in a couple of words: serve the reader and respect the target person. Very common advice on how to arrange the quotations is − firstly, to delete such vernacular cues (e.g. repetitions and ”expletives”) that are common in spoken communication, but purposeless in the written language. − secondly, to complete the phonetic word forms of the spoken language into a more reader-friendly form (esim. punanen → punainen, 'red'), and − thirdly, to enhance the independence of clauses from the (authentic) context and to toughen reciprocal links between them. According to the knowledge of the journalistic field, utterances recorded in different points in time of an interview or a data-collecting session can be transferred as consecutive quotations or even merged together. However, if there is any temporal-spatial location written in the story, the dialogue of the story characters should also be situated in an authentic context – chronologically in the right place in the continuum of the events. To summarize, the way in which the utterances should be arranged into written speech quotations is always situationally-specific − and it is strongly based on the author's discretion.

Analysis of Heterogeneous IP Traffic in Wireless Environment

Wireless access is expected to play a crucial role in the future of the Internet. The demands of the wireless environment are not always compatible with the assumptions that were made on the era of the wired links. At the same time, new services that take advantage of the advances in many areas of technology are invented. These services include delivery of mass media like television and radio, Internet phone calls, and video conferencing. The network must be able to deliver these services with acceptable performance and quality to the end user. This thesis presents an experimental study to measure the performance of bulk data TCP transfers, streaming audio flows, and HTTP transfers which compete the limited bandwidth of the GPRS/UMTS-like wireless link. The wireless link characteristics are modeled with a wireless network emulator. We analyze how different competing workload types behave with regular TPC and how the active queue management, the Differentiated services (DiffServ), and a combination of TCP enhancements affect the performance and the quality of service. We test on four link types including an error-free link and the links with different Automatic Repeat reQuest (ARQ) persistency. The analysis consists of comparing the resulting performance in different configurations based on defined metrics. We observed that DiffServ and Random Early Detection (RED) with Explicit Congestion Notification (ECN) are useful, and in some conditions necessary, for quality of service and fairness because a long queuing delay and congestion related packet losses cause problems without DiffServ and RED. However, we observed situations, where there is still room for significant improvements if the link-level is aware of the quality of service. Only very error-prone link diminishes the benefits to nil. The combination of TCP enhancements improves performance. These include initial window of four, Control Block Interdependence (CBI) and Forward RTO recovery (F-RTO). The initial window of four helps a later starting TCP flow to start faster but generates congestion under some conditions. CBI prevents slow-start overshoot and balances slow start in the presence of error drops, and F-RTO reduces unnecessary retransmissions successfully.

Politiikan paluu : Globalisaatioliike ja julkisuus

The struggle over globalization has arguably been the most important debate in world politics of the 2000 s. This study maps the origins of this debate, its most important actors and its results so far. The focus is on the Global Justice Movement which launched the globalization debate to the mass media spotlight. Particular attention is given to the World Social Forum, the movement s global gathering, analyzed as a new form of global publics. The mediation of the debates initiated by these publics to the Finnish national context is analyzed at two levels: First, through forums for policy debate such as the Helsinki Process on Globalization and Democracy and second, through the public debate in the Finnish mass media. The study proves many common assumptions about the Global Justice Movement wrong. Rather than being a marginal actor, the movement is the initiator of the whole debate. Combining expert knowledge to carnevalistic demonstrations rarely seen in Finland, the movement gains more public attention and more members in Finland than in many other European countries. The political and economic elites are not just adversaries of the movement. Rather, the Finnish elite is divided in two. Some top politicians starting from the president and the minister for foreign affairs adopt many of the movement s claims. Later, the business elite, with support from the nation s largest newspaper, begins a counterattack to challenge the movement and its allies. The return of politics staged by the movement is, first and foremost, a phenomenon in the public sphere. Two downward trends, the decline of party politics and the traditionally strong Finnish field of politically oriented civic associations remain unchanged. This allows for the conclusion that we are witnessing a move from organizational politics towards politics in the public sphere. The study develops a theoretical perspective on social movements as actors in the public sphere. It argues that movements have, in fact, played an important role in the very development of the democratic public sphere as we know it. In the light of this observation, the study assesses the potentials and the pitfalls of social movements and their related publics to global democracy. Methodologically, the most important contribution is the development of Public Justifications Analysis, a method for analyzing political claims in media debates and the ways in which these claims are justified.

Parisuhde ja ero : Sosiologinen analyysi terapeuttisesta ymmärryksestä

This study takes as its premise the prominent social and cultural role that the couple relationship has acquired in modern society. Marriage as a social institution and romantic love as a cultural script have not lost their significance but during the last few decades the concept of relationship has taken prominence in our understanding of the love relationship. This change has taken place in a society governed by the therapeutic ethos. This study uses material ranging from in-depth interviews to various mass media texts to investigate the therapeutic logic that determines our understanding of the couple relationship. The central concept in this study is therapeutic relationship which does not refer to any particular type of relationship. In contemporary usage the relationship is, by definition, therapeutic. The therapeutic relationship is seen as an endless source of conflict and a highly complex dynamic unit in constant need of attention and treatment. Notwithstanding this emphasis on therapy and relationship work the therapeutic relationship lacks any morally or socially defined direction. Here lies the cultural power and according to critics the dubious aspect of the therapeutic ethos. For the therapeutic logic any reason for divorce is possible and plausible. Prosaically speaking the question is not whether to divorce or not, but when to divorce. In the end divorce only attests to the complexity of the relationship. The therapeutic understanding of the relationship gives the illusion that relationships with their tensions and conflicting emotions can be fully transferred to the sphere of transparency and therapeutic processing. This illusion created by relationship talk that emphasizes individual control is called omnipotence of the individual. However, the study shows that the individual omnipotence is inevitably limited and hence cracks appear in it. The cracks in the omnipotence show that while the therapeutic relationship based on the ideal of communication gives an individual a mode of speaking that stresses autonomy, equality and emotional gratification, it offers little help in expressing our fundamental dependence on other people. The study shows how strong an attraction the therapeutic ethos has with its grasp on the complexities of the relationship in a society where divorce is so common and the risk of divorce is collectively experienced.

Stor Anna, Liten Anna och tio andra personporträtt : Om innehållsliga och språkliga mönster i en mediegenres kvinnobeskrivningar

The aim of this licentiate thesis is to analyse how femininity is constructed in twelve portrait interviews of women in the dailies Dagens Nyheter (Stockholm) and Hufvudstadsbladet (Helsinki) in September 1996, and to explore the portrait interview as a media genre. The qualitative analysis has a feminist and constructionist perspective and is connected to critical text analysis. It was carried out on two levels: first, femininity is identified on the linguistic level by choice of words, and second on the level of content (topical motifs/themes). The portrait interview as a genre constitutes a third dimension in the analysis: The aim is not towards the identification of femininity, but rather towards the identification of the portrait interview a relatively unexplored media genre. References (Swedish: omtal) to the principal character (or protagonist) are traced mainly through reference chains which consist of names, pronouns and substantive phrases. The interviewees were referred to by their full names in Dagens Nyheter (with the exception of the oldest and youngest interviewees, both of whom were mainly referred to by their first names), while the style of reference varied more in Hufvudstadsbladet. The position of the principal character was also analysed through her relation in the text to minor characters from her working life and from her private life. These minor characters maintained their subordinate positions in all of the portraits except that of the youngest principal character, in which the subsidiary voices became at least as strong as the voice of the principal character. Three frequently-recurring topical motifs occurred in the portraits: The first involved explanations for the principal character s success divided into three categories, agent, affect and ambition, the second concerned using journeys or trips as symbols for turning points in life, and the third referred to the ambiguity in the contradiction between private (family/other private life) and public (work) life. This ambiguity is connected to the portrait interview as a text type (genre) which features conclusions at the end of portraits, which in turn is characteristic of reportage. However, the analysis showed that the conclusions of the portrait interviews often also included elements of ambiguity. This was evident in the contradictions be14 tween private and public life that arose in the portrait interviews that focused on these two spheres. The portraits that focused on the principal character s public life showed ambiguity on a more general level concerning questions about being a woman and having a profession, and they often ended with a description of some details of her private life. The women in the portraits were all constructed as being successful, in terms of having achieved direct success, reflective success or success in the form of life wisdom. The women of direct success were described as ambitious individuals with no sidetracks on their life paths, while those of reflective success were described as active heroines who had received help from different agents, who could use their affects as enriching ingredients in life, but who in the end had control over their own lives (life stories). The elderly women were constructed as having achieved life wisdom and their portraits were focused upon the past. The portrait interview as a genre is characterised by journalistic freedom (in relation to the more strict news genre), by a now room (Swedish nurum ) where the journalist meets the principal character (usually via spoken dialogue that she or he transforms into written text to be read by a mass-media audience) and by the relatively closed structure of the portrait. The portrait is relatively independent in relation to the news genre and in relation to the context of what has previously been written, what is being written at the time and what will be written in the future the principal character does not need to belong to the newspaper s usual gallery of actors. Furthermore, the principal character is constructed as being independent in relation to the subsidiary characters and other media actors. The conflict is within the principal character herself and within her life story, unlike the news genre in which equal actors are in conflict with each other. The portrait is also independent in relation to the news lifespan; the publishing timetable is not as strict as in the news genre, but is still dependent on the factors initiating the portrait. The enclosures consist of a raw analysis of two of twelve portrait interviews and of copies of all portraits.

Words as Events : Cretan Mantinádes in Performance and Composition

Words as Events introduces the tradition of short, communicative rhyming couplets, the mantinádes, which are still sung and recited in a variety of performance situations on the island of Crete. The local focus on communicative economy and artistry is further examined in an in-depth analysis of the processes and ideals of composition. Short genres of oral poetry have been widely neglected in folklore research; however, their demand for structural and semantic coherence as well as their dialogic nature appeals to very different human needs from those of the longer poems. In contemporary Crete, poems also appear in written contexts, they are submitted to modern mass media, and people widely exchange them as text messages. By striving to understand the tradition during a period of change, this study analyzes the larger principles that ground the communication, self-expression and creativity in the genre. The aim of this research is thus twofold: to present this specific register of dialogic oral poetry as well as to create a theoretical approach sensitive to the creativity of such short registers. The study is based on long-term ethnographic fieldwork conducted in Crete between the years 1997 2009. An important aspect of the methodology was to create long-term ties with a number of key-informants who composed mantinádes. The interdisciplinary theoretical and methodological basis for this analysis is in the contemporary Finnish and international research on oral poetry and on anthropological research on communicative speech genres. These theoretical insights are extended by addressing questions of spontaneity and individual agency. Since mantinádes are at the same time a model for composition and a reserve of poems in fixed form, the aesthetics and objectives of performance and composition are also plural. In a traditional singing event, the basic motivation for the singers is to provide a meaningful contribution to a selected theme, which is the shared topic of the poetic dialogue. Consequently, similar topics giving rise to poetic associations can be encountered during various moments of everyday life: the dialogic nature is embodied in the tradition to such degree that it also arises in the performances and composition of single poems and outside of any institutionalized performance arenas. Therefore, as this study discusses in detail, even the apparently non-contextualized poems recited between locals or occurring in the contemporary mass media arenas, are understood and evaluated as utterances that provide an individual perspective within a certain dialogue.

Sterol-binding proteins in late endosomes : Regulation of endosome motility and lipid metabolism

Despite its bad reputation in the mass media, cholesterol is an indispensable constituent of cellular membranes and vertebrate life. It is, however, also potentially lethal as it may accumulate in the arterial intima causing atherosclerosis or elsewhere in the body due to inherited conditions. Studying cholesterol in cells, and research on how the cell biology of cholesterol affects on system level is essential for a better understanding of the disease states associated with cholesterol and for the development of new therapies for these conditions. On its way to the cell, exogenous cholesterol traverses through endosomes, transport vesicles involved in internalizing material to cells, and needs to be transported out of this compartment. This endosomal pool of cholesterol is important for understanding both the common disorders of metabolism and the more rare hereditary disorders of cholesterol metabolism. The study of cholesterol in cells has been hampered by the lack of bright fluorescent sterol analogs that would resemble cholesterol enough to be used in cellular studies. In the first study of my thesis, we present a new sterol analog, Boron-Dipyrromethene (BODIPY)-cholesterol for visualizing sterols in living cells and organism. This fluorescent cholesterol derivative is shown to behave similarly to cholesterol both by atomic scale computer simulations and biochemical experiments. We characterize its localization inside different types of living cells and show that it can be used to study sterol trafficking in living organisms. Two sterol binding proteins associated with the endosomal membrane; the Niemann-Pick type C disease protein 1 (NPC1) and the Oxysterol Binding Protein Related Protein 1 (ORP1) are the subjects of the rest of this study. Sensing cholesterol on endosomes, transporting lipids away from this compartment and the effects these lipids play on cellular metabolism are considered. In the second study we characterize how the NPC1 protein affects lipid metabolism. We show that this cholesterol binding protein affects synthesis of triglycerides and that genetic polymorphisms or a genetic defect in the NPC1 gene affect triglyceride on the whole body level. These effects take place via regulation of carbon fluxes to different lipid classes in cells. In the third part we characterize the effects of another endosomal sterol binding protein, ORP1L on the function and motility of endosomes. Specifically we elucidate how a mutation in the ability of ORP1L to bind sterols affects its behavior in cells, and how a change in ORP1L levels in cells affects the localization, degradative capacity and motility of endosomes. In addition we show that ORP1L manipulations affect cholesterol balance also in macrophages, a cell type important for the development of atherosclerosis.

“And now to the rest of the trash…” Representations of begging Roma and an ideal society in two Nordic newspapers

Since begging East European Roma became a common view in the streets of larger Nordic cities, vivid discussions about their presence and activities have been carried out in the mass media. This thesis examines the public debates in Finland and Norway through a discursive analysis and comparison of press content from the two countries. The aim of the study is firstly to identify the prominent discourses which construct certain images of the beggars, as well as the elements and internal logics that these discourses are constructed around. But in addition to scrutinizing representations of the Roma, also an opposite perspective is applied. In accordance with the theoretical concept of ‘othering’, debates about ‘them’ are assumed to simultaneously reveal something significant about ‘us’. The second research question is thus what kind of images of the ideal Finnish and Norwegian societies are reflected in the data, and which societal values are salient in these images. The analysis comprises 79 texts printed in the main Finnish and Norwegian quality newspapers; Helsingin Sanomat and Aftenposten. The data consists of news articles, editorials, columns and letters to the editor from a three-month period in the summer of 2010. The analysis was carried out within the theoretical and methodological framework of critical discourse analysis as outlined by Norman Fairclough. A customized nine-step coding scheme was developed in order to reach the most central dimensions of the texts. Seven main discourses were identified; the Deprivation-solidarity, Human rights, Order, Crime, Space and majority reactions, Authority control, and Authority critique discourse. These were grouped into two competing normative stances on what an ideal society looks like; the exclusionary and the inclusionary stance. While the exclusionary stance places the begging Roma within a frame of crime, illegitimate use of public space and threat to the social order, the other advocates an attitude of solidarity and humanitarian values. The analysis points to a dominance of the former, although it is challenged by the latter. The Roma are “individualized” by quoting and/or presenting them by name in a fair part of the Finnish news articles. In Norway, the opposite is true; there the beggars are dominantly presented as anonymous and passive. Overall, the begging Roma are subjected to a double bind as they are faced with simultaneous expectations of activity and passivity. Theories relating to moral panics and ‘the good enemy’ provide for a deepened understanding of the intensity of the debates.

Juoksuhaudoista yhteiskuntaan : Vuosien 1965-1975 sotilaallista maanpuolustusta ja puolustusvoimia koskevan joukkotiedotuksen diskursiivinen tarkastelu

The Finnish society developed rapidly in the 1960´s and 1970´s. This was result of international trends. Development of education, urbanization and wide organization of society increased discontent towards prevailing social structure and towards the power elite. Development of technology created possibility to present radical perspectives in mass media. This caused widely spread discussions dividing opinions. The purpose of this thesis was to complement research on national defence and the Finnish Defence Forces especially between years 1965 and 1975. The task of research was to clarify how changes in society and how the significance of this change was interpreted in public discussion about national defence and development of the Defence Forces. The most essential points for this thesis turned out to be discourses structured from public discussion. Main research material consisted of approximately 35000 news, editorials, articles and opinions presented in mass media supplemented by literature, committee reports and other archival sources. Frame of reference for this thesis is based on relativistic worldview. According to this, social reality is relative and there is no single truth. Environment has significant influence on the issue how knowledge and truth are formed. Data analysis was based on critical discourse. The key objective was to clarify the effects of broad changes in society using discursive methods. One essential goal was to form order of discourse using linguistic analysis and also connect discourses to wider sociocultural custom. On this thesis I came to the conclusion that on the review period there were five significant ensembles of discourse. They consisted of several discussions focused on different themes. The discourse of official security policy aimed to define national defence and the position of the Defence Forces as parts of foreign policy. Foreign policy is often perceived as the most significant part of security policy. Historical memory, geographical position of Finland and also the state contracts, changes in international warfare, tasks of the Defence Forces and increasing critic of national defence and the difference in thinking between generations formed the discourse of security policy. In the discourse of the liability to military service, the issue was about individual responsibility to society and national defence. Resisters and unarmed defence demands, encouraged by international examples were the themes. The discourse pointed out how mass media is used to influence and forced the Defence Forces to develop the practices in public information. The discourses of democracy and politics were closer to internal development of the Defence Forces to integrate more into society. The discourse of democracy focused in changing power relationships of the Defence Forces that were known as authoritarian. Issues like conscript and personnel union activity had lot of similarities to general social development. The discourse of politics presented how the Defence Forces were pushed towards parliamentary decision making. The personnel was granted the same rights as other population. Themes related to the discourse on the will to national defence were development of mental national defence, increasing education on national defence and creation of more open public information culture. According to discourses presented above I can state, that the position of the Defence Forces in society was changed between years 1965-1975. This change was advanced by the Defence Forces reformed attitude towards mass media and public information in general. Active participation in public information important became important instead of only answering topics. This positive development created an atmosphere, that was easier for the public to understand and create own pictures of the armed forces. Due to this, I can describe that the defenders and supporters of the armed forces were stuck in their trenches, until discussions presented in discourses and themes developed the Defence Forces to be better fitting part of society. Key words; society, national defence, Defence Forces, discourse, mass media, security policy, liability to military service, conscription, democracy

Optimal control of information epidemics modeled as Maki Thompson rumors

We model the spread of information in a homogeneously mixed population using the Maki Thompson rumor model. We formulate an optimal control problem, from the perspective of single campaigner, to maximize the spread of information when the campaign budget is fixed. Control signals, such as advertising in the mass media, attempt to convert ignorants and stiflers into spreaders. We show the existence of a solution to the optimal control problem when the campaigning incurs non-linear costs under the isoperimetric budget constraint. The solution employs Pontryagin's Minimum Principle and a modified version of forward backward sweep technique for numerical computation to accommodate the isoperimetric budget constraint. The techniques developed in this paper are general and can be applied to similar optimal control problems in other areas. We have allowed the spreading rate of the information epidemic to vary over the campaign duration to model practical situations when the interest level of the population in the subject of the campaign changes with time. The shape of the optimal control signal is studied for different model parameters and spreading rate profiles. We have also studied the variation of the optimal campaigning costs with respect to various model parameters. Results indicate that, for some model parameters, significant improvements can be achieved by the optimal strategy compared to the static control strategy. The static strategy respects the same budget constraint as the optimal strategy and has a constant value throughout the campaign horizon. This work finds application in election and social awareness campaigns, product advertising, movie promotion and crowdfunding campaigns. (C) 2014 Elsevier B.V. All rights reserved.

Los medios como formadores de la imagen de los políticos

Resumen: Cuando los medios se refieren a los candidatos políticos en una situación de campaña electoral proyectan una cierta imagen de los mismos a partir de las verbalizaciones que preponderan en los mensajes informativos. El presente trabajo analiza estas verbalizaciones de los medios en el marco de la teoría de la Agenda Setting, más específicamente en el segundo nivel de esta teoría, la cual hace referencia a los atributos o aspectos que caracterizan a los protagonistas de las noticias, para este estudio en particular, los políticos. Esta teoría fue puesta a prueba repetidamente desde su aplicación en las elecciones estadounidenses de 1968 de la mano de sus autores Maxwell McCombs y Donald Shaw. La misma se ha extendido con paso firme desde su país de origen hacia otras latitudes. El objetivo general es describir la imagen de los candidatos presidenciales a partir de las expresiones que preponderan en los medios masivos de comunicación, durante la campaña presidencial en Argentina ocurrida en octubre de 2011. El procedimiento consiste en el relevamiento realizado durante los meses anteriores a las elecciones presidenciales. Para ello fue necesario armar un corpus compuesto por la selección de los medios masivos de comunicación a analizar. Seguidamente se realiza el análisis de contenido del corpus y se procede al análisis de los datos, de ello deriva una base de datos, donde la unidad de análisis fue la mención de los diversos aspectos o características de los candidatos políticos. Los aspectos o características fueron tomados de investigaciones anteriores que aplicaron la misma metodología y que fueron realizadas en nuestro país también en situaciones de contextos electorales. Por ello es factible de efectuar comparaciones en el tiempo, ya que una de las enormes riquezas de la teoría de la Agenda Setting es la de ser susceptible de comparación por tratarse de una metodología de análisis sistemático. La revisión de la teoría de la Agenda Setting que enmarca esta investigación pretende introducirnos primeramente en las investigaciones de medios masivos en general para luego focalizar en la teoría propiamente dicha y más aún en el segundo nivel de la teoría que trata de los atributos de los personajes públicos Se realiza posteriormente una breve sinopsis de investigaciones en Latinoamérica y Argentina, sobre temas relacionados con campañas electorales y no electorales para finalmente de manera concatenada dar cuenta de trabajos realizados en nuestro país en situaciones de campañas políticas

Hacia la aldea virtual : evolución de las tecnologías comunicativas y de los modelos antropológicos

Estudiar los medios de comunicación significa estudiar al hombre, la sociedad en la que vive, su evolución y las perspectivas de desarrollo futuro. Después de haber puntualizado brevemente los avances tecnológicos salientes en la historia del hombre y de haber identificado las características más relevantes de las diversas redefiniciones antropológicas que siguieron a la introducción de algunos nuevos medios, nos detendremos principalmente en el estudio de las peculiaridades de los instrumentos de comunicación de masa más modernos, de la fotografía al cine, de la televisión a Internet. El objetivo principal de este aporte, lejos de querer proveer sistemas teóricos definitivos, es trazar un conjunto coherente de temáticas capaces de suscitar nuevas y proficuas cuestiones y de promover un debate abierto a los más diversos aportes, con particular atención a los avances de las comunicaciones telemáticas.
