Sukupolvien ongelma : Tutkielmia sukupolven käsitteestä, sukupolvitietoisuudesta ja suurista ikäluokista

The aims of the thesis are (1) to present a systematic evaluation of generation and its relevance as a sociological concept, (2) to reflect on how generational consciousness, i.e. generation as an object of collective identification that has social significance, can emerge and take shape, (3) to analyze empirically the generational experiences and consciousness of one specific generation, namely Finnish baby boomers (b. 1945 1950). The thesis contributes to the discussion on the social (as distinct from its genealogical) meaning of the concept of generation, launched by Karl Mannheim s classic Das Problem der Generationen (1928), in which the central idea is that a certain group of people is bonded together by a shared experience and that this bonding can result in a distinct self-consciousness. The thesis is comprised of six original articles and an extensive summarizing chapter. In the empirical articles, the baby boomers are studied on the basis of nationally representative survey data (N = 2628) and narrative life-story interviews (N = 38). In the article that discusses the connection of generations and social movements, the analysis is based on the member survey of Attac Finland (N = 1096). Three main themes were clarified in the thesis. (1) In the social sense the concept of generation is a modern, problematic, and ultimately a political concept. It served the interests of the intellectuals who developed the concept in the early 20th century and provided them, as an alternative to the concept of social class, a new way of think about social change and progress. The concept of generation is always coupled with the concept of Zeitgeist or some other controversial way of defining what is essential, i.e. what creates generations, in a given culture. Thus generation is, as a product of definition and classification struggles, a contested concept. The concept also clearly implies elitist connotations; the idea of some kind of vanguard (the elite) that represents an entire generation by proclaiming itself as its spokesman automatically creates a counterpart, namely the others in the peer group who are thought to be represented (the masses). (2) Generational consciousness cannot emerge as a result of any kind of automatic process or endogenously; it must be made. There has to be somebody who represents the generation in order for that generation to exist in people s minds and as an object of identification; generational experiences and their meanings must be articulated. Hence, social generations are, in a fundamental manner, discursively constructed. The articulations of generational experiences (speeches, writings, manifests, labels etc.) can be called as the discursive dimension of social generations, and through this notion, how public discourse shapes people s generational consciousness can be seen. Another important element in the process is collective memory, as generational consciousness often takes form only retrospectively. (3) Finnish baby boomers are not a united or homogeneous generation but are divided into many smaller sections with specific generational experiences and consciousnesses. The content of the generational consciousness of the baby boomers is heavily politically charged. A salient dividing line inside the age group is formed by individual attitudes towards so-called 1960s radicalism. Identification with the 1960s generation functions today as a positive self-definition of a certain small leftist elite group, and the values and characteristics usually connected with the idea of the 1960s generation do not represent the whole age group. On the contrary, among some of the members of the baby boomers, the generational identification is still directed by the experience of how traditional values were disgraced in the 1960s. As objects of identification, the neutral term baby boomers and the charged 1960s generation are totally different things, and therefore they should not be used as synonyms. Although the significance of the group of the 1960s generation is often overestimated, they are however special with respect to generational consciousness because they have presented themselves as the voice of the entire generation. Their generational interpretations have spread through the media with the help of certain iconic images of the generation insomuch that 1960s radicalism has become an indirect generational experience for other parts of the baby boom cohort as well.

Nota sullo status della gallina prataiola (Tetrax tetrax) nella Zona di Protezione Speciale Piana di Semestene, Bonorva, Macomer e Bortigali (Sardegna), 2007-2009

The little bustard Tetrax tetrax is a bird of agro-pastoral landscapes rapidly disappearing from most of Western Europe due to agricultural intensification. In Italy, the species is virtually extinct from the mainland but still occurs in Sardinia, where four Special Protection Areas (SPAs) have been designated in 2007 to protect the bustard and related habitat. In this note, we document a steep decline (between 50 and 87,5%) of the species during the last decade in one of those four SPAs, Plains of Semestene, Bonorva, Macomer and Bortigali. However, during summer 2009, a group of 17 individuals was found within the SPA, confirming that the species, although at low numbers (5-15 displaying males), still breeds successfully in the area. Potential limiting factors are also discussed. We urge to undertake conservation measures based on solid scientific evidence if the local population is to be saved from probable extinction in the near future.

Occupational chronic solvent encephalopathy in Finland 1995 - 2007 : incidence and diagnostic methods

The occurrence of occupational chronic solvent encephalopathy (CSE) seems to decrease, but still every year reveals new cases. To prevent CSE and early retirement of solvent-exposed workers, actions should focus on early CSE detection and diagnosis. Identifying the work tasks and solvent exposure associated with high risk for CSE is crucial. Clinical and exposure data of all the 128 cases diagnosed with CSE as an occupational disease in Finland during 1995-2007 was collected from the patient records at the Finnish Institute of Occupational Health (FIOH) in Helsinki. The data on the number of exposed workers in Finland were gathered from the Finnish Job-exposure Matrix (FINJEM) and the number of employed from the national workforce survey. We analyzed the work tasks and solvent exposure of CSE patients and the findings in brain magnetic resonance imaging (MRI), quantitative electroencephalography (QEEG), and event-related potentials (ERP). The annual number of new cases diminished from 18 to 3, and the incidence of CSE decreased from 8.6 to 1.2 / million employed per year. The highest incidence of CSE was in workers with their main exposure to aromatic hydrocarbons; during 1995-2006 the incidence decreased from 1.2 to 0.3 / 1 000 exposed workers per year. The work tasks with the highest incidence of CSE were floor layers and lacquerers, wooden surface finishers, and industrial, metal, or car painters. Among 71 CSE patients, brain MRI revealed atrophy or white matter hyperintensities or both in 38% of the cases. Atrophy which was associated with duration of exposure was most frequently located in the cerebellum and in the frontal or parietal brain areas. QEEG in a group of 47 patients revealed increased power of the theta band in the frontal brain area. In a group of 86 patients, the P300 amplitude of auditory ERP was decreased, but at individual level, all the amplitude values were classified as normal. In 11 CSE patients and 13 age-matched controls, ERP elicited by a multimodal paradigm including an auditory, a visual detection, and a recognition memory task under single and dual-task conditions corroborated the decrease of auditory P300 amplitude in CSE patients in single-task condition. In dual-task conditions, the auditory P300 component was, more often in patients than in controls, unrecognizable. Due to the paucity and non-specificity of the findings, brain MRI serves mainly for differential diagnostics in CSE. QEEG and auditory P300 are insensitive at individual level and not useful in the clinical diagnostics of CSE. A multimodal ERP paradigm may, however, provide a more sensitive method to diagnose slight cognitive disturbances such as CSE.

Representation av kvinnor och män – Hur prioriterar riksdagsledamöter frågor i den finska riksdagen? En kvantitativ studie av motionerna i riksdagen 2007

Pro gradu uppsatsen diskuterar betydelsen av representation för grupper i samhället genom att diskutera kvinnors representation. Kvinnor är en grupp i samhället som länge varit underrepresenterad, men som under de senaste 100 åren fått en betydligt bättre position i den offentliga beslutfattningen. För att ge bakgrund till frågeställningen beskrivs kvinnors deltagande i den finska riksdagen. Begreppen deskriptiv, substantiell och symbolisk representation diskuteras. Undersökningar av kvinnors representation både deskriptivt och substantiellt på parlamentsnivå presenteras. Forskningsfrågan i uppsatsen består av fyra frågeställningar om hur motioner görs i riksdagen och hur kön kan identifieras i motionerna. Frågeställningarna bygger på den teoretiska diskussionen och meningen med frågeställningar är att styra analysen av motionerna. I teoriavsnittet behandlas kvinnors representation och den vetenskapliga diskussionen om sambandet mellan substantiell och deskriptiv representation. Diskussionen utgår från Hanna Pitkins olika kategorier av representation. I den teoretiska diskussionen behandlas även begreppen den kritiska massan, närvarons politik och kritiska aktörer. I stycket diskuteras även vilka frågeställningar, som är relevanta att undersöka när man diskuterar kvinnors representation i samhället. När representationen av kvinnor diskuteras är det viktigt att minnas att kvinnor inte utgör en homogen grupp och att även män kan representera kvinnor innehållsmässigt. Efter den teoretiska diskussionen presenteras metoden för undersökningen. Som metod används kvantitativa statistiska metoder för att kunna undersöka ett större material, som kan ge en bättre helhetsbild av hur kvinnor representeras i motionerna. Materialet för undersökningen är motioner som är gjorda i den finska riksdagen 2007. Resultaten i undersökningen visar att motionerna används av både opposition och regering och att det finns en möjlighet för samarbete över partigränser. Andra faktorer, som påverkade hur aktivt man gjorde motioner var bland annat riksdagsledamöternas ålder och den valregion ledamöterna var från. När man såg speciellt på motionärernas kön framkom det skillnader i kvinnors och mäns motionsbeteende. Överlag gör män mera motioner än kvinnor i den finska riksdagen. Kvinnor har än idag en större tendens att göra motioner om socialpolitik och speciellt familje- och barnpolitik än vad män har. Männen igen väljer att göra motioner, som traditionellt har setts som starkt manliga, så som trafik och allmänna utrymmen. Resultaten visade också att kvinnors intressen inte är vanligt som motivering för motioner. Man fann också att riksdagsledamöters koppling till kvinnoorganisationer hade en betydelse när det gällde sannolikheten att göra motioner som motiverades med kvinnors intressen i samhället. Uppsatsen diskuterar orsaker till resultaten och ser att det finns orsaker att fortsätta diskutera sambandet mellan deskriptiv och substantiell representation.

Kyynpurema koiralla, kirjallisuuskatsaus ja Yliopistollisen Eläinsairaalan potilasaineistoa vuosilta 2007 - 2008

Kyykäärme (Vipera berus) on Suomen ainoa myrkkykäärme, ja sitä esiintyy lähes koko maassa Pohjois-Lappia lukuun ottamatta. Kyy on yleensä helposti tunnistettavissa selän tummasta sahalaitakuviosta. Käärme ei ole perusluonteeltaan hyökkäävä, vaan pyrkii ensisijaisesti pakenemaan. Koira kuitenkin pääsee monesti yllättämään kyyn ennen kuin käärme ehtii paeta, jolloin se puolustautuessaan saattaa purra rajusti. Kaikki puremat eivät sisällä myrkkyä, vaan noin kolmasosa puremista on ns. kuivapuremia. Kyynpuremia raportoidaan eniten maalis- ja lokakuun välisenä aikana. Kyynpuremasta aiheutuvat oireet ovat koiralla vaihtelevia, ja eläimen voinnin kehittymisen ennustaminen ensioireiden perusteella on vaikeaa. Oireet vaihtelevat paikallisesta turvotuksesta henkeä uhkaavaan monielinvaurioon. Koiralla kuolleisuuden on raportoitu olevan 3,5 – 4 %. Kyynmyrkyn koostumusta ei vielä tarkalleen tunneta, mutta sen pääkomponentin muodostavat suurimolekyyliset proteiinit ja polypeptidit, joista osalla on entsymaattista aktiivisuutta. Lisäksi osalla myrkyn komponenteista vaikuttaisi olevan suoraa toksista vaikutusta kohdekudokseen, esimerkiksi munuaisiin. Keskeisintä kyynpureman patofysiologiassa on myrkyn sytotoksisen komponentin ja proteolyyttisten entsyymien aiheuttama verisuonten endoteelivaurio, jonka seurauksena suonet alkavat vuotaa. Kehittyvä voimakas kudosturvotus on kyynpureman tyypillisin oire, ja se ilmaantuu aina kahden tunnin sisällä puremasta, mikäli purema on sisältänyt myrkkyä. Nesteiden siirtyminen verisuoniston ulkopuolelle johtaa nopeasti hypovolemiaan ja shokkiin. Tärkeiden sisäelinten verenkierto heikkenee, jolloin solut kärsivät hapen ja ravinteiden puutteesta. Myrkky stimuloi myös sytokiinien tuotantoa ja vapautumista elimistöstä. Näiden farmakologisesti aktiivisten aineiden vapautuminen pahentaa systeemioireita, aiheuttaa lihasspasmeja ja on pääasiallisesti kyynpuremasta aiheutuvan voimakkaan kivun taustalla. Kyynmyrkyn sisältämät vieraat proteiinit voivat aiheuttaa myös anafylaktisen reaktion. Tutkimusosan aineisto koostuu 12 koirasta, joita hoidettiin kyynpureman takia Yliopistollisen Eläinsairaalan teho-osastolla vuosina 2007 – 2008. Koirista 10 toipui kotiutuskuntoon ja kaksi jouduttiin lopettamaan komplikaatioiden takia. Tutkimuksessa tarkasteltiin potilaiden virtsa- ja seeruminäytteistä määritettyjä munuaisten toimintaa kuvaavia laboratorioarvoja ja verrattiin lopetettujen koirien arvoja selvinneiden koirien vastaaviin. Tarkoituksena oli selvittää, onko selvinneiden ja lopetettujen välillä havaittavissa eroja, ja että onko tiettyjen laboratoriomääritysten perusteella mahdollista sanoa jotakin potilaan selviytymisennusteesta. Tuloksissa todettiin eroja selvinneiden ja lopetettujen koirien välillä. Virtsasta mitatut munuaisten solutuhoa kuvaavat entsyymiaktiivisuudet (AFOS/C ja GGT/C) sekä virtsan proteiinit kreatiniiniin suhteutettuna olivat lopetetulla selvästi korkeammat kuin selvinneillä koirilla. Myös seeruminäytteissä todettiin eroja. Tulosten perusteella vaikuttaakin siltä, että lopetetuilla koirilla vauriot munuaisissa olivat pahemmat kuin selvinneillä koirilla. Tutkimuksen aineisto oli kuitenkin niin pieni, että tuloksia voidaan pitää ainoastaan suuntaa antavina.

An optimal weighted-average congestion based pricing scheme for enhanced QoS, , LNCS 4882, 2007

Pricing is an effective tool to control congestion and achieve quality of service (QoS) provisioning for multiple differentiated levels of service. In this paper, we consider the problem of pricing for congestion control in the case of a network of nodes under a single service class and multiple queues, and present a multi-layered pricing scheme. We propose an algorithm for finding the optimal state dependent price levels for individual queues, at each node. The pricing policy used depends on a weighted average queue length at each node. This helps in reducing frequent price variations and is in the spirit of the random early detection (RED) mechanism used in TCP/IP networks. We observe in our numerical results a considerable improvement in performance using our scheme over that of a recently proposed related scheme in terms of both throughput and delay performance. In particular, our approach exhibits a throughput improvement in the range of 34 to 69 percent in all cases studied (over all routes) over the above scheme.

Climate change and crop yields in the Indian Cardamom Hills, 1978-2007 CE

In this study we analyzed climate and crop yields data from Indian cardamom hills for the period 1978-2007 to investigate whether there were significant changes in weather elements, and if such changes have had significant impact on the production of spices and plantation crops. Spatial and temporal variations in air temperatures (maximum and minimum), rainfall and relative humidity are evident across stations. The mean air temperature increased significantly during the last 30 years; the greatest increase and the largest significant upward trend was observed in the daily temperature. The highest increase in minimum temperature was registered for June (0.37A degrees C/18 years) at the Myladumpara station. December and January showed greater warming across the stations. Rainfall during the main monsoon months (June-September) showed a downward trend. Relative humidity showed increasing and decreasing trends, respectively, at the cardamom and tea growing tracts. The warming trend coupled with frequent wet and dry spells during the summer is likely to have a favorable effect on insect pests and disease causing organisms thereby pesticide consumption can go up both during excess rainfall and drought years. The incidence of many minor pest insects and disease pathogens has increased in the recent years of our study along with warming. Significant and slight increases in the yield of small cardamom (Elettaria cardamomum M.) and coffee (Coffea arabica), respectively, were noticed in the recent years.; however the improvement of yield in tea (Thea sinensis) and black pepper (Piper nigrum L.) has not been seen in our analysis.

Remote sensing study of snowline altitude at the end of melting season, Chandra-Bhaga basin, Himachal Pradesh, 1980-2007

Glaciers have a direct relation with climate change. The equilibrium line altitude (ELA) is the most useful parameter to study the effect of climate change on glaciers. The ELA is a theoretical snowline at which the glacier mass balance is zero. Snowline altitude (SLA) at the end of melting season is generally regarded as the ELA. Glaciers of Chandra-Bhaga basin in Lahaul-Spiti district of Himachal Pradesh were chosen to study the ELA, using satellite images from 1980 to 2007. A total of 19 glaciers from the Chandra-Bhaga basin were identified and selected to carry out the study of ELA variation over 27 years. This study reveals that the mean SLA of the sub-basin has increased from 5009 +/- 61m to 5401 +/- 21m from 1980 to 2007. The study is in agreement with the reported increase in the temperature and decrease in winter snowfall of North-West Himalaya in the last century.

Surface freshwater storage and variability in the Amazon basin from multi-satellite observations, 1993-2007

The amount of water stored and moving through the surface water bodies of large river basins (river, floodplains, wetlands) plays a major role in the global water and biochemical cycles and is a critical parameter for water resources management. However, the spatiotemporal variations of these freshwater reservoirs are still widely unknown at the global scale. Here, we propose a hypsographic curve approach to estimate surface freshwater storage variations over the Amazon basin combining surface water extent from a multi-satellite-technique with topographic data from the Global Digital Elevation Model (GDEM) from Advance Spaceborne Thermal Emission and Reflection Radiometer (ASTER). Monthly surface water storage variations for 1993-2007 are presented, showing a strong seasonal and interannual variability, and are evaluated against in situ river discharge and precipitation. The basin-scale mean annual amplitude of similar to 1200 km(3) is in the range of previous estimates and contributes to about half of the Gravity Recovery And Climate Experiment (GRACE) total water storage variations. For the first time, we map the surface water volume anomaly during the extreme droughts of 1997 (October-November) and 2005 (September-October) and found that during these dry events the water stored in the river and floodplains of the Amazon basin was, respectively, similar to 230 (similar to 40%) and 210 (similar to 50%) km(3) below the 1993-2007 average. This new 15 year data set of surface water volume represents an unprecedented source of information for future hydrological or climate modeling of the Amazon. It is also a first step toward the development of such database at the global scale.

Determinacion de brucelosis en la poblacion canina en ocho barrios del distrito dos de Managua utilizando el metodo de Rosa de Bengala y Rivanol en Septiembre - Diciembre 2007

En Nicaragua se desconoce la situación actual nacional de Brucelosis en la población canina, debido a que solo se ha realizado un estudio en la zona urbana y suburbana de la ciudad de León acerca de esta enfermedad en esta especie. La importancia del estudio consiste en beneficiar a propietarios y criadores de razas caninas, a los profesionales de la medicina veterinaria que se dedican a las especies menores y técnicos de laboratorios, brindándoles información acerca de la situación de esta enfermedad para ser tomada en cuenta en su labor diaria. Con el objetivo de determinar la prevalencia de brucelosis en caninos con la colaboración del ministerio de salud (MINSA) durante la jornada de vacunación antirrábica se realizó un muestreo serológico en canes en los barrios Bo Monseñor Lezcano, Las Palmas, Santa Ana Norte, San Sebastián, Bóer, San José, Acahualinca y Batahola Norte del Distrito II de Managua en los meses de Septiembre a Diciembre del año 2007. Se recolectó un total de 100 sueros de canes de ambos sexos, sin categorizarlos por su raza y edad en el momento de la toma de las muestras, las cuales se analizaron por el método Rosa de Bengala (antígeno Brucella abortus cepa 1119-3)en el Centro Veterinario de Diagnóstico de investigación, Unidad de Microbiología UNAN -León y como prueba confirmatoria se utilizó Rivanol 1% en el laboratorio del MAGFOR Unidad de Sanidad Animal León. Los resultados obtenidos para el primer método fue de un reactor correspondiente una hembra de 2 meses de edad de raza no definida del barrio Las Palmas que posteriormente resultó negativa a la prueba de Rivanol. La prevalencia encontrada es del 0%.

Diagnostico de prevalencia a leptospirosis canina con respecto a las variables edad, sexo y raza, en ocho barrios del distrito 2 de la ciudad de Managua Septiembre 2007 - Enero 2008

La leptospirosis es considerada una de las zoonosis más difundidas en el mundo entero. El perro actúa como un potencial diseminador de esta enfermedad ya que mantiene una estrecha relación con el hombre, y al mismo tiempo con otros animales tanto domésticos como salvajes. Con el objetivo de conocer la presencia de leptospirosis canina, se realizó estudio en ocho barrios del distrito dos de la cuidad de Managua entre 8 de septiembre al 9 de diciembre 2007. Se realizó un muestreo de 76 canes, correspondiente al 5% del total de canes en los ocho barrios. Se extrajo 3ml de sangre de la vena safena externa, luego de procesarlas para separar el suero sanguíneo del plasma mediante centrifugación, fueron trasladadas al laboratorio del Centro Veterinario de Diagnóstico e Investigación CEVEDI, UNAN-León, para su análisis mediante los métodos ELISA y MAT. De acuerdo con los resultados obtenidos mediante la prueba ELISA un 93.4%, 71 canes, son negativos y un 6.6%, o bien 5 especímenes, son seropositivos a Leptospira spp. Según los resultados de la prueba de micro aglutinación MAT, el 96.1% de la población muestreada es negativa y el 3.9% es positiva a leptospirosis encontrándose los siguientes serovares canico/a, icterohemorragiae, pyrogenes.

Visualization Summit 2007: Ten research goals for 2010

At the first international Visualization Summit, more than 100 international researchers and practitioners defined and assessed nine original and important research goals in the context of Visualization Science, and proposed methods for achieving these goals by 2010. The synthesis of the whole event is presented in the 10th research goal. This article contributes a building block for systemizing visualization research by proposing mutually elaborated research goals with defined milestones. Such a consensus on where to go together is only one step toward establishing visualization science in the long-term perspective as a discipline with comparable relevance to chemistry, mathematics, language, or history. First, this article introduces the conference setting. Second, it describes the research goals and findings from the nine workshops. Third, a survey among 62 participants about the originality and importance of each research goal is presented and discussed. Finally, the article presents a synthesis of the nine research goals in the form of a 10th research goal, namely Visualizing Future Cities. The article is relevant for visualization researchers, trend scouts, research programme directors who define the topics that get funds. © 2007 Palgr aveMacmillan Ltd. All rights reserved.
