Fin de millénaire eli maailmanlopun satiiri : Frédéric Beigbederin Au secours pardon, Marie Darrieussecqin Truismes ja Michel Houellebecqin La Possibilité d'une île

Pro gradu -työni käsittelee ranskalaisen nykykirjallisuuden yhteiskunnallista suuntausta, jota kirjallisuudentutkija Ruth Cruickshank kutsuu fin de millénaire -kirjallisuudeksi. Tutkimani teokset ovat Frédéric Beigbederin Au secours pardon (2007), Marie Darrieussecqin Truismes (1996) ja Michel Houellebecqin La Possibilité d'une île (2005). Pohdin, millaisena ja millaisin keinoin teokset kuvaavat seksuaalisuutta ja sen tulevaisuudennäkymiä kulutusyhteiskunnassa, ja millaisiin yhteiskunnallisiin olosuhteisiin niiden havainnot perustuvat. Hahmottelen reittejä, joita pitkin globaalin mittakaavan yhteiskunnalliset muutokset vaikuttavat ihmisten intiimeihin tunteisiin ja ihmissuhteisiin. Seksuaalisuuden tarkastelun avulla osoitan, että ranskalaisessa nykykirjallisuudessa ilmenee varsin yhteneviä näkemyksiä ja uhkakuvia aikamme sosiaalisesta todellisuudesta. Tällä tavoin tarkennan ja vankennan vielä hajanaista fin de millénaire -käsitettä. Fin de millénaire -kirjallisuuden oma lajityyppi on massakulttuurin, esimerkiksi viihteen ja mainosten, kielestä vaikutteita ammentava dystopian ja satiirin liitto. Kuten Cruickshank kirjoittaa, fin de millénaire -kirjallisuus heijastaa Ranskassa vuosituhannen vaihteessa korostunutta tunnetta käännekohtaan saapumisesta. Dystopian ohella voidaankin puhua myös apokalyptisesta tekstistä, etenkin siksi, että teokset tarjoavat niukasti ratkaisuja kuvaamiinsa ongelmiin. Eritoten Houellebecqin ja Beigbederin teokset käsittelevät tarpeiden luomista kuluttajille seksuaalivietin ja seksuaalisen kilpailun avulla. Kutsun tätä järjestelmää halutaloudeksi, ja käytän sen toiminnan analysoimisessa apuna Michel Foucault'n käsityksiä vallasta ja Jean Baudrillardin käsityksiä kulutusyhteiskunnasta. Halutalouden sosiaalisia seurauksia ovat vieraantuminen, seksuaalisten hierarkioiden jyrkentyminen ja valinnanvapauden kaventuminen. Teosten kuvaamassa yhteiskunnassa erilaiset esimerkiksi sukupuolen, iän ja ulkonäön perusteella rakentuvat seksuaaliset hierarkiat käyvät yhä merkittävämmiksi. Au secours pardon ja La Possibilité d'une île kuvaavat tapahtumaketjua, jossa etenkin heteromiehistä yhä useampi luisuu seksuaaliseen kurjuuteen muun muassa naisten emansipaation sekä yleisen nuoruuden ja kauneuden palvonnan myötä. Truismesissa taas kuvitellaan yhteiskunta, johon feminismi ei ole päässyt vaikuttamaan mutta pornoistuminen on; naisten ruumiista on tullut miesten yhteistä omaisuutta ja seksuaalinen väkivalta on arkipäivää. Sen maailmassa viehättävä ulkonäkö on naisille miltei elinehto. Yleistäen Houellebecqin ja Beigbederin teokset edustavat miesnäkökulmaa ja Darrieussecqin teos naisnäkökulmaa. Teosten näkemyksiä naisten ja miesten välisistä valtasuhteista pohdin naisten seksuaalisesta vallasta kirjoittaneen Henry Laasasen käyttökelpoisten käsitteiden avulla. Kolmea teosta yhdistävät kuvaukset kulttuurista, jossa ihmissuhteet ovat kaupankäyntiä ja seksuaalinen viehätysvoima määrittelee ihmisen arvon. Darrieussecqin teos on lähitulevaisuuteen sijoittuva dystopia, jossa Beigbederin ja Houellebecqin kuvaama arvoliberalismia ja taloudellista liberalismia yhdistävä kulttuuri on vaihtunut uuskonservatiiviseen ja kaksinaismoralistiseen, naisia räikeästi sortavaan yhteiskuntaan. Teoksen kertoja vähättelee itseensä kohdistuvia koskemattomuuden loukkauksia ja pahoittelee kertomuksensa käänteiden säädyttömyyttä varsinkin kuvatessaan omaa haluaan ja seksuaalista subjektiuttaan. Katson teoksen kritisoivan kirjallisuudentutkija Shirley Ann Jordanin termein poliittisen korrektiuden tyranniaa ja peräänkuuluttavan suoraa puhetta pornografiasta ja naisen halusta. Seksuaalisuus toimii tutkimuksessani lähtökohtana, jonka avulla teoksista nousee esiin julma ja rakkaudeton, säälimättömän kilpailun ja väkivallan täyttämä yhteiskunta. Viime kädessä teosten kuvaama maailmanloppu on se, että rakkaus katoaa ihmisten välisistä suhteista, koska rakkaudessa ei ole voiton tavoittelun kannalta mitään järkeä. Satiirin keinojen, kuten päättymättömän ja monikerroksisen ironian, yhdistyminen dystopiaan pelastaa teokset osoittelevalta moralisoinnilta ja tekee niistä toimivaa yhteiskunnallista kirjallisuutta.

Les fleuves dans l'œuvre romanesque de Jean-Marie Gustave Le Clézio

Relying on Merleau-Ponty's phenomenology of perception and on Mircea Eliade's works on the Sacred and the Profane, this study explores the river as a perceptual space and as the sacred Center in a cosmic vision of the world in twelve of Jean-Marie Gustave Le Clézio's fictional works, from The Interrogation (1963) to Revolutions (2003). In the first chapter, after introducing the field of study, I discuss the relation between the radical subjectivity and the evasiveness of perceiving subjects in Le Clézio's fiction. Next are some thoughts on the relation between Merleau-Ponty's and Le Clézio's ideas. The second chapter studies the river as an experience in the text, first as a topographical space, then as a sound world. The investigations move on to its water as a visual and a tactile phenomenon. Then follows the human use of the river, the (absence of) baths, and the river as a traveling space. The chapter closes with the study of the metaphorical use of the word, occurring mainly in urban space and for phenomena in the sky. The third chapter is organized around the river as the Center of the world in a religious cosmogony, where the river represents the origin of the world and of the human race. The core analysis shows how the middle of the river is a symbolic space of a new beginning. As a sacred space, the river abolishes time as the object of contemplation and as relative immobility from the point of view of a person drifting downstream. The functions of a new beginning and of abolition of time are combined in the symbolic immersions in the water. Finally, the dissertation explores other symbolical spaces, such as the unknown destination of the drift, and the river as the Center of a utopia. The chapter closes with the existential agony as a result of the elimination of the Center in the urban environment. In the final chapter, the river is compared to other watercourses : the creek, the brook and the rapids. The river is more of a spatial entity, whereas the actual water is more important in the smaller watercourses. The river is more common than the other watercourses as a topographical element in the landscape, whereas the minor watercourses invite the characters to a closer contact with their element, in immersions and in drinking their water. Finally, the work situates the rivers in a broader context of different fictional spaces in Le Clézio's text.

Cohésion modale et subordination : Le conditionnel et le jussif finnois au miroir de la valeur sémantique et discursive du subjonctif français

Modal cohesion and subordination. The Finnish conditional and jussive moods in comparison to the French subjunctive This study examines verb moods in subordinate clauses in French and Finnish. The first part of the analysis deals with the syntax and semantics of the French subjunctive, mood occurring mostly in subordinate positions. The second part investigates Finnish verb moods. Although subordinate positions in Finnish grammar have no special finite verb form, certain uses of Finnish verb moods have been compared to those of subjunctives and conjunctives in other languages. The present study focuses on the subordinate uses of the Finnish conditional and jussive (i.e. the third person singular and plural of the imperative mood). The third part of the analysis discusses the functions of subordinate moods in contexts beyond complex sentences. The data used for the analysis include 1834 complex sentences gathered from newspapers, online discussion groups and blog texts, as well as audio-recorded interviews and conversations. The data thus consist of both written and oral texts as well as standard and non-standard variants. The analysis shows that the French subjunctive codes theoretical modality. The subjunctive does not determine the temporal and modal meaning of the event, but displays the event as virtual. In a complex sentence, the main clause determines the temporal and modal space within which the event coded by the subjunctive clause is interpreted. The subjunctive explicitly indicates that the space constructed in the main clause extends its scope over the subordinate clause. The subjunctive can therefore serve as a means for creating modal cohesion in the discourse. The Finnish conditional shares the function of making explicit the modal link between the components of a complex construction with the French subjunctive, but the two moods differ in their semantics. The conditional codes future time and can therefore occur only in non-factual or counterfactual contexts, whereas the event expressed by French subjunctive clauses can also be interpreted as realized. Such is the case when, for instance, generic and habitual meaning is involved. The Finnish jussive mood is used in a relatively limited number of subordinate clause types, but in these contexts its modal meaning is strikingly close to that of the French subjunctive. The permissive meaning, typical of the jussive in main clause positions, is modified in complex sentences so that it entails inter-clausal relation, namely concession. Like the French subjunctive, the jussive codes theoretical modal meaning with no implication of the truth value of the proposition. Finally, the analysis shows that verb moods mark modal cohesion, not only on the syntagmatic level (namely in complexe sentences), but also on the paradigmatic axis of discourse in order to create semantic links over entire segments of talk. In this study, the subjunctive thus appears, not as an empty category without function, as it is sometimes described, but as an open form that conveys the temporal and modal meanings emerging from the context.

Correlation filtering: a terrain correction method for aeromagnetic maps with application

In correlation filtering we attempt to remove that component of the aeromagnetic field which is closely related to the topography. The magnetization vector is assumed to be spatially variable, but it can be successively estimated under the additional assumption that the magnetic component due to topography is uncorrelated with the magnetic signal of deeper origin. The correlation filtering was tested against a synthetic example. The filtered field compares very well with the known signal of deeper origin. We have also applied this method to real data from the south Indian shield. It is demonstrated that the performance of the correlation filtering is superior in situations where the direction of magnetization is variable, for example, where the remnant magnetization is dominant.

Metamorphic-metasomatic fluids and Al, Si order/disorder of K-rich alkali feldspars from southern Indian high grade terrain

The structural state of K-feldspars in the quartzofeldspathic gneisses, charnockites, metapelites and pegmatites from the southern Kamataka, northern Tamil Nadu and southern Kerala high-grade regions of southern India has been characterized using petrographic and powder X-ray diffraction methods. The observed distribution pattern of structural state with a preponderance of disordered K-feldspar polymorphs in granulites compared to the ordered microclines in the amphibolite facies rocks is interpreted to reflect principally the varying H2O contents in the metamorphic-metasomatic fluids across metamorphic grade. The K-feldspars in the pegmatites of granitic derivation and in a pegmatite of inferred metamorphic origin also point to the important role of aqueous fluids in their structural state.

Chaotic and power law states in the Portevin-Le Chatelier effect

Recent studies on the Portevin-Le Chatelier effect report an intriguing crossover phenomenon from low-dimensional chaotic to an infinite-dimensional scale-invariant power law regime in experiments on CuAl single crystals and AlMg polycrystals, as function of strain rate. We devise fully dynamical model which reproduces these results. At low and medium strain rates, the model is chaotic with the structure of the attractor resembling the reconstructed experimental attractor. At high strain rates, power law statistics for the magnitudes and durations of the stress drops emerge as in experiments and concomitantly, the largest Lyapunov exponent is zero.

A dynamical model for the Portevin-le Chatelier bands

We show that an extension of Ananthakrishna's model to include spatial degrees of freedom produces spatially uncorrelated bands, hopping type and the continuously propagating type with increasing applied strain rate. The velocity of the continuously propagating bands is found to vary linearly with applied strain rate. (C) 2003 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.

Calculating the Effect of Uneven Terrain on Glide Path Signals

A method for calculating the bends in the glide slope due to uneven terrain is presented. A computer program written for the purpose enables the calculation of the difference in depth of modulation (DDM) at any point, taking into account the effect of uneven terrain. Results are presented for a hypothetical case of a hill in front of the runway. The program enables us to predict the glide slope bends due to irregular terrain, so that proper selection of glide slope antenna location can be made.

A THREE-WHEELED MOBILE ROBOT FOR TRAVERSING UNEVEN TERRAIN WITHOUT SLIP: SIMULATION AND EXPERIMENTS

A wheeled mobile robot (WMR) can move on uneven terrains without slip if the wheels are allowed to tilt laterally. This paper deals with the analysis, design and experimentations with a WMR where the wheels can tilt laterally. The wheels of such a WMR must be equipped with two degrees of freedom suspension mechanism. A prototype three-wheeled mobile robot is fabricated with a two degree-of-freedom suspension mechanism. Simulations show that the three-wheeled mobile robot can traverse uneven terrains with very little slip and experiments with the prototype on a representative uneven terrain confirm that the slip is significantly reduced.

SPATIO-TEMPORAL DYNAMICS ALONG THE TERRAIN GRADIENT OF DIVERSE LANDSCAPE

Land use (LU) land cover (LC) information at a temporal scale illustrates the physical coverage of the Earth's terrestrial surface according to its use and provides the intricate information for effective planning and management activities. LULC changes are stated as local and location specific, collectively they act as drivers of global environmental changes. Understanding and predicting the impact of LULC change processes requires long term historical restorations and projecting into the future of land cover changes at regional to global scales. The present study aims at quantifying spatio temporal landscape dynamics along the gradient of varying terrains presented in the landscape by multi-data approach (MDA). MDA incorporates multi temporal satellite imagery with demographic data and other additional relevant data sets. The gradient covers three different types of topographic features, planes; hilly terrain and coastal region to account the significant role of elevation in land cover change. The seasonality is another aspect to be considered in the vegetation dominated landscapes; variations are accounted using multi seasonal data. Spatial patterns of the various patches are identified and analysed using landscape metrics to understand the forest fragmentation. The prediction of likely changes in 2020 through scenario analysis has been done to account for the changes, considering the present growth rates and due to the proposed developmental projects. This work summarizes recent estimates on changes in cropland, agricultural intensification, deforestation, pasture expansion, and urbanization as the causal factors for LULC change.

Correlation between band propagation property and the nature of serrations in the Portevin-Le Chatelier effect

We investigate the correlation between the band propagation property and the nature and amplitude of serrations in the Portevin-Le Chatelier effect within the framework of the Ananthakrishna model. Several significant results emerge. First, we find that spatial and temporal correlations continuously increase with strain rate from type C to type A bands. Consequently, the nature of the bands also changes continuously from type C to A bands, and so do the changes in the associated serrations. Second, even the smallest extent of propagation induces small amplitude serrations. The spatial extent of band propagation is directly correlated with the duration of small amplitude serrations, a result that is consistent with recent experiments. This correspondence allows one to estimate the spatial extent of band propagation by just measuring the temporal stretch of small amplitude serrations. Therefore, this should be of practical value when only stress versus strain is recorded. Third, the average stress drop magnitude of the small amplitude serrations induced by the propagating bands remains small and nearly constant with strain rate. As a consequence, the fully propagating type A bands are in a state of criticality. We rationalize the increasing levels of spatial and temporal correlations found with increasing strain rates. Lastly, the model also predicts several band morphologies seen in experiments including the Luders-like propagating band. (C) 2015 Acta Materialia Inc. Published by Elsevier Ltd.

A mobile robot with a two-degree-of-freedom suspension for traversing uneven terrain with minimal slip: Modeling, simulation and experiments

It is known in literature that a wheeled mobile robot (WMR) with fixed length axle will slip on an uneven terrain. One way to avoid wheel slip is to use a torus-shaped wheel with lateral tilt capability which allows the distance between the wheel-ground contact points to change even with a fixed length axle. Such an arrangement needs a two degree-of-freedom (DOF) suspension for the vertical and lateral tilting motion of the wheel. In this paper modeling, simulation, design and experimentation with a three-wheeled mobile robot, with torus-shaped wheels and a novel two DOF suspension allowing independent lateral tilt and vertical motion, is presented. The suspension is based on a four-bar mechanism and is called the double four-bar (D4Bar) suspension. Numerical simulations show that the three-wheeled mobile robot can traverse uneven terrain with low wheel slip. Experiments with a prototype three-wheeled mobile robot moving on a constructed uneven terrain along a straight line, a circular arc and a path representing a lane change, also illustrate the low slip capability of the three-wheeled mobile robot with the D4Bar suspension.
