La biologie de la conservation est communément associée à la protection de petites populations menacées d?extinction. Pourtant, il peut également être nécessaire de soumettre à gestion des populations surabondantes ou susceptibles d?une trop grande expansion, dans le but de prévenir les effets néfastes de la surpopulation. Du fait des différences tant quantitatives que qualitatives entre protection des petites populations et contrôle des grandes, il est nécessaire de disposer de modèles et de méthodes distinctes. L?objectif de ce travail a été de développer des modèles prédictifs de la dynamique des grandes populations, ainsi que des logiciels permettant de calculer les paramètres de ces modèles et de tester des scénarios de gestion. Le cas du Bouquetin des Alpes (Capra ibex ibex) - en forte expansion en Suisse depuis sa réintroduction au début du XXème siècle - servit d?exemple. Cette tâche fut accomplie en trois étapes : En premier lieu, un modèle de dynamique locale, spécifique au Bouquetin, fut développé : le modèle sous-jacent - structuré en classes d?âge et de sexe - est basé sur une matrice de Leslie à laquelle ont été ajoutées la densité-dépendance, la stochasticité environnementale et la chasse de régulation. Ce modèle fut implémenté dans un logiciel d?aide à la gestion - nommé SIM-Ibex - permettant la maintenance de données de recensements, l?estimation automatisée des paramètres, ainsi que l?ajustement et la simulation de stratégies de régulation. Mais la dynamique d?une population est influencée non seulement par des facteurs démographiques, mais aussi par la dispersion et la colonisation de nouveaux espaces. Il est donc nécessaire de pouvoir modéliser tant la qualité de l?habitat que les obstacles à la dispersion. Une collection de logiciels - nommée Biomapper - fut donc développée. Son module central est basé sur l?Analyse Factorielle de la Niche Ecologique (ENFA) dont le principe est de calculer des facteurs de marginalité et de spécialisation de la niche écologique à partir de prédicteurs environnementaux et de données d?observation de l?espèce. Tous les modules de Biomapper sont liés aux Systèmes d?Information Géographiques (SIG) ; ils couvrent toutes les opérations d?importation des données, préparation des prédicteurs, ENFA et calcul de la carte de qualité d?habitat, validation et traitement des résultats ; un module permet également de cartographier les barrières et les corridors de dispersion. Le domaine d?application de l?ENFA fut exploré par le biais d?une distribution d?espèce virtuelle. La comparaison à une méthode couramment utilisée pour construire des cartes de qualité d?habitat, le Modèle Linéaire Généralisé (GLM), montra qu?elle était particulièrement adaptée pour les espèces cryptiques ou en cours d?expansion. Les informations sur la démographie et le paysage furent finalement fusionnées en un modèle global. Une approche basée sur un automate cellulaire fut choisie, tant pour satisfaire aux contraintes du réalisme de la modélisation du paysage qu?à celles imposées par les grandes populations : la zone d?étude est modélisée par un pavage de cellules hexagonales, chacune caractérisée par des propriétés - une capacité de soutien et six taux d?imperméabilité quantifiant les échanges entre cellules adjacentes - et une variable, la densité de la population. Cette dernière varie en fonction de la reproduction et de la survie locale, ainsi que de la dispersion, sous l?influence de la densité-dépendance et de la stochasticité. Un logiciel - nommé HexaSpace - fut développé pour accomplir deux fonctions : 1° Calibrer l?automate sur la base de modèles de dynamique (par ex. calculés par SIM-Ibex) et d?une carte de qualité d?habitat (par ex. calculée par Biomapper). 2° Faire tourner des simulations. Il permet d?étudier l?expansion d?une espèce envahisseuse dans un paysage complexe composé de zones de qualité diverses et comportant des obstacles à la dispersion. Ce modèle fut appliqué à l?histoire de la réintroduction du Bouquetin dans les Alpes bernoises (Suisse). SIM-Ibex est actuellement utilisé par les gestionnaires de la faune et par les inspecteurs du gouvernement pour préparer et contrôler les plans de tir. Biomapper a été appliqué à plusieurs espèces (tant végétales qu?animales) à travers le Monde. De même, même si HexaSpace fut initialement conçu pour des espèces animales terrestres, il pourrait aisément être étndu à la propagation de plantes ou à la dispersion d?animaux volants. Ces logiciels étant conçus pour, à partir de données brutes, construire un modèle réaliste complexe, et du fait qu?ils sont dotés d?une interface d?utilisation intuitive, ils sont susceptibles de nombreuses applications en biologie de la conservation. En outre, ces approches peuvent également s?appliquer à des questions théoriques dans les domaines de l?écologie des populations et du paysage.<br/><br/>Conservation biology is commonly associated to small and endangered population protection. Nevertheless, large or potentially large populations may also need human management to prevent negative effects of overpopulation. As there are both qualitative and quantitative differences between small population protection and large population controlling, distinct methods and models are needed. The aim of this work was to develop theoretical models to predict large population dynamics, as well as computer tools to assess the parameters of these models and to test management scenarios. The alpine Ibex (Capra ibex ibex) - which experienced a spectacular increase since its reintroduction in Switzerland at the beginning of the 20th century - was used as paradigm species. This task was achieved in three steps: A local population dynamics model was first developed specifically for Ibex: the underlying age- and sex-structured model is based on a Leslie matrix approach with addition of density-dependence, environmental stochasticity and culling. This model was implemented into a management-support software - named SIM-Ibex - allowing census data maintenance, parameter automated assessment and culling strategies tuning and simulating. However population dynamics is driven not only by demographic factors, but also by dispersal and colonisation of new areas. Habitat suitability and obstacles modelling had therefore to be addressed. Thus, a software package - named Biomapper - was developed. Its central module is based on the Ecological Niche Factor Analysis (ENFA) whose principle is to compute niche marginality and specialisation factors from a set of environmental predictors and species presence data. All Biomapper modules are linked to Geographic Information Systems (GIS); they cover all operations of data importation, predictor preparation, ENFA and habitat suitability map computation, results validation and further processing; a module also allows mapping of dispersal barriers and corridors. ENFA application domain was then explored by means of a simulated species distribution. It was compared to a common habitat suitability assessing method, the Generalised Linear Model (GLM), and was proven better suited for spreading or cryptic species. Demography and landscape informations were finally merged into a global model. To cope with landscape realism and technical constraints of large population modelling, a cellular automaton approach was chosen: the study area is modelled by a lattice of hexagonal cells, each one characterised by a few fixed properties - a carrying capacity and six impermeability rates quantifying exchanges between adjacent cells - and one variable, population density. The later varies according to local reproduction/survival and dispersal dynamics, modified by density-dependence and stochasticity. A software - named HexaSpace - was developed, which achieves two functions: 1° Calibrating the automaton on the base of local population dynamics models (e.g., computed by SIM-Ibex) and a habitat suitability map (e.g. computed by Biomapper). 2° Running simulations. It allows studying the spreading of an invading species across a complex landscape made of variously suitable areas and dispersal barriers. This model was applied to the history of Ibex reintroduction in Bernese Alps (Switzerland). SIM-Ibex is now used by governmental wildlife managers to prepare and verify culling plans. Biomapper has been applied to several species (both plants and animals) all around the World. In the same way, whilst HexaSpace was originally designed for terrestrial animal species, it could be easily extended to model plant propagation or flying animals dispersal. As these softwares were designed to proceed from low-level data to build a complex realistic model and as they benefit from an intuitive user-interface, they may have many conservation applications. Moreover, theoretical questions in the fields of population and landscape ecology might also be addressed by these approaches.

Genetics is the study of heredity, which means the study of genes and factors related to all aspects of genes. The scientific history of genetics began with the works of Gregor Mendel in the mid-19th century. Prior to Mendel, genetics was primarily theoretical whilst, after Mendel, the science of genetics was broadened to include experimental genetics. Developments in all fields of genetics and genetic technology in the first half of the 20th century provided a basis for the later developments. In the second half of the 20th century, the molecular background of genetics has become more understandable. Rapid technological advancements, followed by the completion of Human Genome Project, have contributed a great deal to the knowledge of genetic factors and their impact on human life and diseases. Currently, more than 1800 disease genes have been identified, more than 2000 genetic tests have become available, and in conjunction with this at least 350 biotechnology-based products have been released onto the market. Novel technologies, particularly next generation sequencing, have dramatically accelerated the pace of biological research, while at the same time increasing expectations. In this paper, a brief summary of genetic history with short explanations of most popular genetic techniques is given.

The advertising poster's main characteristic is the ability to convey a commercial message quickly and publicly thanks to its straightforward image and text. The young people, being the tobacco industry's principal target, are particularly exposed to these messages. This kind of advertisement becomes a mean of counterstroke as soon as the cigarette's harmfulness is acknowledged. Some of the cigarette industry's strategies can be revealed by the historical analysis of a 253 posters corpus selected among the main cigarette manufacturers in Switzerland at the time of the post-war economic boom. With the misuse of sport's theme, the overvaluation of the filter's efficiency, the use of a vocabulary that implies lightness and by erasing the image of smoke in its advertisement, the industry tries to reassure the smoker wrongly.

The aim of this study is to provide an effective and quick reference guide based on the most useful European formulae recently published for subadult age estimation. All of these formulae derive from studies on postnatal growth of the scapula, innominate, femur, and tibia, based on modern skeletal data (173 ♂, 173 ♀) from five documented collections from Spain, Portugal, and Britain. The formulae were calculated from Inverse Regression. For this reason, these formulae are especially useful for modern samples from Western Europe and in particular on 20th century human remains from the Iberian Peninsula. Eleven formulae were selected as the most useful because they can be applied to individuals from within a wide age range and in individuals of unknown sex. Due to their high reliability and because they derive from documented European skeletal samples, we recommend these formulae be used on individuals of Caucasoid ancestry from Western Europe.

A comparative study of the two published Catalan translations of Charles Dickens’ David Copperfield, the first translated by Josep Carner in 1930 but not published until 1964, and the second by Joan Sellent in 2003. The analysis shows that both translations, magnificent, reflect the unique evolution of the language model that the translators pass on to their readers, an evolution shaped by the complex history of the Catalan language in the 20th century, which is still to be written

After 470 years, a history of development, international seed smuggling and scientific development that caused deep changes in our society, has reached an end. In 1638, the countess of Chinchón contracted a disease while in the Amazon rain forest and was healed by a potion used by the native inhabitants. In 1856, William H. Perkin while attempting to obtain synthetic quinine, discovered the mauveína, a molecule that changed the world. The synthesis of quinine was also the subject of a bitter controversy among two excellent scientists of the 20th century. During centuries, quinine was the only hope against malaria disease and its exploration almost extinguished the Cinchona tree.

The home as ethos, an ethical dimension of human beings, is this study’s focus of interest. Can the home as ethos comprise motive and driving force for a human being? This dissertation has a mainly hermeneutic approach with a Caring Science interpretive horizon. Firstly, the purpose of this study is to develop the concept “home” through etymological and semantic analysis. The concept’s Caring Science content is also investigated. Secondly, the purpose of this study is to investigate, through the use of a history of ideas method, how the home as ethos is made visible and evident in public health nurses’ caring during the first half of the 20th century. Which motives compromise the driving force behind public health nurses’ caring? Which idea patterns are stressed? Material for the study’s concept determination consists of tymological dictionaries as well as Swedish language dictionaries published from 1850 – 2001. The results of the concept determination provide a preliminary idea-model, where dimensions such as ethos as a human being’s innermost room, human beings’ manner of being, and the metaphor “my home is my castle” are stressed. These results comprise the background of the history of ideas portion of the study. The study’s history of ideas investigation occurs through the evaluation and interpretation of historical sources focusing on the caring provided by public health nurses. Public health nurses comprise both the context and prevalent traditions during the time-period studied. The historical sources consist of three different types of sources, namely textbooks, archived material, and the professional nursing journals Epione and Sairaanhoitajatarlehti. The purpose is to rediscover fundamental idea-patterns through the thematic structuring of the patterns appearing in the historical sources. Three main idea-patterns and underlying themes are rediscovered: love- a fire which burns inside human beings; reverence for human beings and home; and the honor of responsibility. The emerging patterns are tightly interwoven and form a pattern. A new interpretation occurs, widening the study’s horizon and leading to the emergence of the theory-model’s contours. The study’s theory-model is formed from three different levels. Ethos as a human being’s innermost room- the spirit, encompasses a human being’s value base and the spirit that he/she is permeated with. Fundamental values are converted into an internal ethic, becoming visible in human beings’ manner of being- the manner of conduct. The metaphor “my home is my castle”- the tone, symbolizes the room where a human being’s abstract or concrete being lives. The spirit, the ethos, is expressed in a home’s culture and atmosphere, that is to say the tone of a home or how one lives in a room. Communion is a significant component in the creation of a culture and atmosphere. This study’s theory-model gives rise to a new perspective that can generate new patterns of action. The study’s theory-model results in a new historically-based view that create new patterns of action in care and Caring Science today.

The present study examines the repertory of liturgical chant known as St. Petersburg Court Chant which emerged within the Imperial Court of St. Petersburg, Russia, and appeared in print in a number of revisions during the course of the 19th century, eventually to spread throughout the Russian Empire and even abroad. The study seeks answers to questions on the essence and composition of Court Chant, its history and liturgical background, and most importantly, its musical relationship to other repertories of Eastern Slavic chant. The research questions emerge from previous literary accounts of Court Chant (summarized in the Introduction), which have tended to be inaccurate and generally not based on critical research. The study is divided into eight main chapters. Chapter 1 provides a survey of the history of Eastern Slavic chant and the Imperial Court Chapel of St. Petersburg until 1917, with special emphasis on the history of singing traditional chant in polyphony, the status of the Court Chapel as a government authority, and its endeavours in publishing church music. Chapter 2 deals with the liturgical background of Eastern chant, the chant genres, and main repertories of Eastern Slavic chant. Chapter 3 concentrates on chant sources: it introduces the musical notations utilised, after which a typology of chant books is presented. The discussion continues with a survey of the sources of Court Chant and their content, the specimens selected for closer analysis, the comparative materials from other repertories, and ends with a commentary on some chant sources that have been excluded. The comparative sources include a specimen from around the beginning of the 12th century, a few manuscripts from the 17th century, and printed and manuscript chant books from the early 18th to early 20th century, covering the geographical area that delimits to the western Ukraine, Astrakhan, Nizhny Novgorod, and the Solovetsky Monastery. Chapter 4 presents the approach and methods used in the subsequent analytical comparisons. After a survey of the pitch organization of Eastern Slavic chant, the customary harmonization strategy of traditional chant polyphony is examined, according to which a method for meaningful analysis of the harmony is proposed. The method is based on the observation that the harmonic framework of chant polyphony derives from the standard pitch collection of monodic chant known as the Church Gamut, specific pitches of which form eight harmonic regions that behave like the usual tonalities of major and harmonic minor. Because of the considerable quantity of comparative chant forms, computer-assisted statistical methods are applied to the analysis of chant melodies. The primary chant forms and their respective comparative forms have been pre-processed into reduced chant prototypes and divided into redactions. The analyses are carried out by measuring the formal dissimilarities of the primary chant forms of the Court Chant repertory against each comparative form, and also by measuring the reciprocal dissimilarities of all chant versions in a redaction, the results of which are subjected to agglomerative hierarchical clustering in order to find out how the chant forms relate to each other. The dissimilarities are determined by applying a metric dissimilarity function that is based on the Levenshtein Distance. Chapter 5 provides the melodic and harmonic analyses of generic chants (chants used for multiple texts of different lengths), i.e., chants for stichera samoglasny and troparia, Chapter 6 of pseudo-generic chants (chants that are used for multiple texts but with certain restrictions), i.e., chants for heirmoi, prokeimena, and three other hymns, and Chapter 7 of non-generic chants, covering nine chants that in the Court repertory are not shared by multiple texts. The results are summarized and evaluated in Chapter 8. Accordingly, it can be established that, contrary to previous conceptions, melodically, Court Chant is in effect a full part of the wider Eastern Slavic chant tradition. Even if it is somewhat detached from the chant versions of the Synodal square-note chant books and the local tradition of Moscow, it is particularly close to chant forms of East Ukraine and some vernacular repertories from Russia. Respectively, the harmonization strategies of Court Chant do not show significant individuality in comparison with those of the available polyphonic comparative sources, the main difference being the part-writing, which generally conforms to western common practice standard, whereas the deviations from this tend to be more significant in other analysed repertories of polyphonic chant. Thus, insofar as the subsequent prevalence of Court Chant is not based on its forceful dissemination by authorities (as suggested in previous literature but for which little tangible evidence could be found in Chapter 1), in the present author’s interpretation, Court Chant attained its dominance principally because musically it was considered sufficiently traditional, and as a chant body supported by the government, was conveniently available in print in serviceable harmonizations.

The wars the Western armies are involved with today are different from those that were fought in the end of 20th century. To explain this change, the Western military thinkers have come up with various different types of definitions of warfare over the last 30 years, each describing the tendencies involved in the conflicts of the time. The changing nature of conflicts surfaced a new term – hybrid warfare. The term was to describe and explain the multi-modality and complexity of modern day conflict. This thesis seeks the answer for the question: what is the development of thought behind hybrid warfare? In this thesis the Vietnam War (1965-1975) is used as an example of compound warfare focusing on the American involvement in the war. The Second Lebanon War (2006) serves as an example of hybrid warfare. Both case studies include an irregular opposing force, namely National Liberation Front in Vietnam War and Hezbollah in the Second Lebanon War. These two case studies are compared with the term full spectrum operations introduced in the current U.S. Department of Army Field Manual No. 3-0 Operations to see the differences and similarities of each term. The perspective of this thesis is the American point of view. This thesis concludes that hybrid warfare, compound warfare and full spectrum operations are very similar. The first two terms are included in the last one. Although hybrid warfare is not officially defined, it will most likely remain to be used in the discussion in the future, since hybrid wars and hybrid threats are officially accepted terms.

Min avhandling är en diakronisk och kontrastiv undersökning av texttyper. Forskningsmaterialet består av kontaktannonser i tidningarna Süddeutsche Zeitung och Helsingin Sanomat under tiden 1900 – 1999. Materialet består av 652 tyska och 538 finska annonser. De undersökta annonserna har publicerats i maj och har samlats från ovannämnda tidningar vart tionde år. Materialet har analyserats med ett statistiskt SPSS-program. I avhandlingen analyseras utvecklingen av ovannämnda texttyp under hundra år i två olika kulturer, den tyska och den finska. Syftet med avhandlingen är att med hjälp av detta material finna språkliga och kulturella likheter och skillnader i kontaktannonser. Utgångspunkten är att språkliga uttryck avspeglar sin tids samhälleliga värderingar, vilka således också påverkar sökandet efter en livskamrat. Analysresultaten granskas sålunda i ett större samhälleligt sammanhang under olika decennier. Annonstexterna undersöks dock inte utgående från enskilda samhälleliga skeenden. Avhandlingen analyserar 13 olika informationsenheter i kontaktannonserna, huruvida dessa enheter förekommer under hela den aktuella perioden och om samma informationsenheter förekommer i annonser i de båda kulturerna. Avhandlingen är sålunda intra- och interlingual samt interkulturell. Genom denna metod får man fram de kännetecken som är betecknande för denna texttyp under en viss tid i de bägge kulturerna. Avhandlingen är indelad i tre delar. Den första delen ger bakgrundsinformation om äktenskapets och familjebegreppets historia samt om uppkomsten av den tyska och finska pressen. Den andra teoretiska delen behandlar text- och texttyplingvistik samt nuvarande forskning inom dessa områden. Den tredje och mest omfattade delen består av en kvalitativ och kvantitativ analys, som omfattar 11 olika forskningsdelar. Undersökningen visar att man i texttypen kontaktannonser kan upptäcka skillnader t ex redan däri att en tysk annons skiljer sig från en finsk vad längd och informationsmängd beträffar. En finsk annons förlitar sig i sin språkliga knapphet på att läsaren förstår kontexten i texttypen. Av avhandlingen framgår också att vid analys av texttyper bör deras historiska och kulturella kontext beaktas, eftersom analysen påvisar att texttyperna är historie- och kulturbundna.

Songs have the power to get through to people. When lyrics are combined with a tune, the result is an entity where the first few notes of a melody can evoke emotions of recognition and belonging. A song treasury consists of such songs that are part of a canonized song tradition. The process where certain songs become part of an established song treasury is long, and many other aspects than the tune itself influence the forming of a song treasury. By examining the characteristics of a song tradition, the history of an ethnic group can be illuminated. In this study, music, pedagogy, and the sociocultural context are merged into a whole where a common song tradition, the song treasury, is in focus. The main aim of this study is to deepen the understanding of a song treasury, its development and contents. This understanding is accomplished by analyzing the musical and lyrical characteristics of 60 songs, which have been sung in schools, homes, and communities, thereby becoming popular among the Swedish-speaking Finns during the 20th century. The songs have been chosen by combining three song lists, of which two lists are closely related to school curricula. The third song list is a result of a survey on favourite songs, according to the situation around year 2000. The songs are examined in their notated versions, a number of song books and text books (n = 29) forming the empirical material. In this study, a hermeneutical approach is applied, content analysis being the method. The analysis is based on three perspectives: the sociocultural perspective, the music-pedagogical perspective, and the musico-analytical perspective. Within each perspective, two aspects are studied. This results in a hexagonal model which forms the structure of the study as a whole. The first two perspectives form the background; a historical context where nation, education, home country, and homestead are regarded as highly important. A common song repertoire is considered to be an effective means of building collective identity within ethnic groups, the common language and the cultural heritage being used as rhetorical arguments. During the early 1900s, choir festivals become an educational platform where conceptions of a common belonging are developed and strengthened through religious, patriotic, and poetical expressions. National school curricula in singing and music have similar characteristics, cultural heritage and values education being in focus. The song lyrics often describe nature and emotions, and they also appear to be personal and situated in a given time and place. Patriotic expressions and songs about music are also fairly common. The songs generally express positive attitudes, which are intensified by major tonality, rich and varied melodies with stable rhythms, and a strong tonal base. The analyzed details of the studied aspects are merged into a thick description, which results in an interpretation pattern with three dimensions: a song treasury can be considered an expression of collective identity, cultural heritage, and values education.

The subject of this thesis is the elaborate silk wallets and what can they tell about the gentry women’s lives in the 18th and 19th century Finland together Jacobina Charlotta Munsterhjelm’s diary. Silk wallets were made of silk and decorated by embroidering, they were used to preserve memorabilia and letters. Making these lavish items took time, skills and materials, and the decorations usually contained symbols and messages. As main source there are silk wallets from the collections of the National Museum of Finland and Satakunta Museum, as well as the diary of Jacobina Munsterhjelm from 1799 to 1801. By interpreting these items we can build a picture of gentry women’s lives. The culture of silk wallets is European, the silk wallet phenomenon studied is Swedish-Finnish, and the research is limited mainly in Finland by its sources. This research has been carried out by constructing a cultural context to the silk wallets with the help of Ginzburg’s methods from his work Juusto ja madot - 1500-luvun myllärin maailmankuva. Silk wallets represent the gentry as well as the communication culture in the 18th and 19th centuries, but have remained unstudied. The thesis consists of two parts, the first focuses on the silk wallets, from where were they developed, how they were made, and to their decorations. The silk wallet culture developed among the gentry handicrafts during the 18th century and faded during the early 20th century. The making of the silk wallets demanded time, skills and materials. The decorations contain messages and symbols – they contain the possible affections the makers might have toward the receiver, and reflect the status and qualities of the receiver. The second part examines the makers, the gentry women, and the handicraft culture which played a big role in their lives, through silk wallets and the diary of Jacobina Munstehjelm. From there it continues to the affections and meanings which can be found from the silk wallets.

Väitöskirjan aihe on, kuinka elokuvanäyttelijän taide ja sitä koskeva ajattelu kehittyivät Venäjällä yksityisen elokuvatuotannon vuosina 1907–1919. Tutkimus kuuluu kulttuurihistorian alaan. Sen näkökulma on elokuvan esteettinen historia, ja tutkimus liittyy ns. revisionistisen elokuvahistorian pyrkimykseen arvioida uudelleen näytelmäelokuvan varhaisvaiheita. Analyysi kohdistuu esteettiseen aikalaisajatteluun sekä elokuvatuotannon käytäntöihin ja prosesseihin. Lähteinä on käytetty elokuvanäyttelemistä koskevaa julkista keskustelua, elokuvantekijöiden jättämää muistietoa ja ajalta säilyneitä elokuvia. Käsittely jakautuu kolmeen väljän kronologisesti järjestettyyn lukuun. Luku 2 keskittyy venäläisen fiktioelokuvan varhaisvuosiin 1910-luvun taitteen molemmin puolin. Luku 3 käsittelee pitkän näytelmäelokuvan läpimurrosta alkunsa saanutta keskustelua psykologisesta elokuvasta. Luku 4 etenee maailmansodan vuosina nouseen kuvallisen, ohjaajakeskeisen elokuvakäsityksen kautta kohti varhaisen neuvostoelokuvan ajatusta näyttelijästä ”mallina”. Väitöskirjassa esitetään, että käsitys näyttelemisestä, ja sitä myötä elokuvasta yleensä, kävi tutkittuna ajanjaksona läpi kehämäisen kehityksen, jossa vuorottelivat käsitykset elokuvasta modernina ja elokuvasta traditiona. Tutkimus problematisoi myöhempää elokuvakäsitystä, jonka mukaan elokuvaestetiikan perusyksikkö on otos. Toisin kuin myöhempinä vuosikymmeninä 1910-luvulla näytteleminen oli avainkysymys, jonka kautta lähestyttiin elokuvan olemusta itseään. Venäjällä ajatukset elokuvanäyttelemisestä kehittyivät vuorovaikutuksessa saman ajan teatteriestetiikan kanssa, joskin elokuva miellettiin jo varhain erilliseksi taidemuodoksi. Tsaarinajan elokuvan vaikutusvaltaisimmaksi esteettiseksi ohjelmaksi muodostui psykologinen elokuva, jonka inspiraationa toimi osittain Konstantin Stanislavskin samaan aikaan kehittämä näyttelijäntyön järjestelmä. Elävä näyttelijä ja näyttelijän ”kokeminen” nähtiin ratkaisuna elokuvavälineen keskeisenä ongelmana pidettyyn mekaanisuuteen. Ajan studiokäytännöissä psykologinen lähestymistapa puolestaan merkitsi usein vastausten etsimistä teollisen elokuvatuotannon olosuhteista syntyneisiin ongelmiin.
