The Ageing in Working Life. Do Adolescence and Schooling Beat Adulthood and Experience? This study examines the changes in the work and the work organisations of employees in the fields of health care and retail trade who have turned 45 and their experience of change. In addition, the question of how ageing employees experience their status in post-modern working life is explored. Attention is also focused on the choices and decisions connected with staying at work and retiring. These views are examined in relation to professions and professional cultures. Thematic interviews (N=98) were used to gather the material. The effects of the market liberalistic turn in welfare policy are clearly seen in the everyday work of the health care professions. These changes were examined from the point of view of managing by outcomes and quality assurance, multi-professional cooperation, flexibility in the division of labour, and the spread of market-like procedures. The discourse of those in involved retail trade was dominated by extremely tight global market competition and control of outcomes, and by the structural changes taking place in the retail trade sector. This change discourse was to a large extent a reaction to those changes in the functional environment which were experienced as negative and to the conflict between their own professional identity and professional ethics on the one hand, and their functional environment on the other. There were also obstacles connected with professional culture: defending one's own station and power, guarding the 'frontier', showed up in attitudes towards new management and organisation models or towards structural and functional reforms. The deep structures of professional culture and the mindset of the actors change much more slowly than the functional practices of organisations. For those in a supervisory position, the loss of power due to becoming part of a chain or because of the introduction of a team organisation model was not an easy thing to accept. The nurses and others in related fields felt that they were forced to do work that was below their level of training and professional skill. For sales personnel and those who did assisting work in health care, power and the possibility of having an influence were not so important, as long as they were able to do their work in their own way and were trusted. This view is often completely forgotten, for example, in various organisation models in which power and the possibility of having an influence entwined with power are taken for granted as being clearly positive and desired aspects of job satisfaction. Up to date professional skills were experienced as being important from the point of view of professional identity and self-worth. Thus, training can be understood as a moral obligation, which in turn is intertwined with professional ideology. In the rhetoric of adult education, an adult is expected to be an active player who will seek training again and again if working life so requires. The dark side of this ideology, which leads to feelings of guilt, was apparent in the thoughts of the respondents. Am I never good enough at my job; why must I continually strive for better, additional qualifications? The majority of the respondents evaluated their expertise as being at quite a high level. This self-confidence did not extend to applying for a job. Job recruitment was seen as a situation in which age discrimination reached its peak. The interviewees were unanimous about the idea that society favours the young. Especially among those in the retail trade sector, there was a feeling that it would be difficult, if not impossible, to find a new job of the same level or a permanent post if they were made redundant. Age discrimination was also apparent in the retail trade field in the form of older employees being retired against their will or transferred to other tasks. It was felt that ruthless forced retirement of older workers was part of the personnel policy of some organisations. The importance of one's outward appearance was connected with the theme of discrimination. This phenomenon is described using the concept of the double standard of ageing in feminist research. An ageing woman is relegated to an inferior position due to both her age and her sex. A culture that would both make possible and allow various types of choices regardless of age, which is described as being characteristic of the post-modern era, does not seem to be very topical in the practice of working life. It is important for employees that the management and the personnel policy that is being implemented makes them feel like both their contribution and they as individuals are appreciated, that their opinions are listened to and that they are noticed as persons. The interviewees hoped for gratitude and a concern for the well-being of employees that shows in everyday life. They valued training and activities aimed at maintaining their work ability, but thought that better coping at work and a pleasant working environment cannot be achieved through such measures as along as the foundation is 'in a mess'. Development of the quality of working life is the only thing that can improve job satisfaction and get people to remain in the work force longer than at present. There should be a sufficient number of properly trained employees at the work place. It was important to the respondents that they be able to stay on their job to the end with honour, since compromising with their own quality standards or acting contrary to their ideal self-image in terms of professional ethics would strike a blow to their professional self-esteem. They called for the development of various types of workplace flexibility, and felt that they have the right to a lightened workload and to early retirement. Early retirement was even seen as an altruistic deed: it would free up a place for younger workers. Thoughts of retirements were explained by familiar factors such as health and finances, life situation, the enticement of free-time, as well as by various factors related to work. It is very important to ageing employees that their work has meaningful content. The values related to self-fulfilment are felt to be of great importance, and if they cannot be realised at work, the respondents wanted more free time, either through retirement or in the form of flexibility in working life.

Spatial and Spectral Separability of Grasslands in the inner Turku Archipelago using Landsat Thematic Mapper Satellite Imagery

The present study investigates the spatial and spectral discrimination potential for grassland patches in the inner Turku Archipelago using Landsat Thematic Mapper satellite imagery. The spatial discrimination potential was computed through overlay analysis using official grassland parcel data and a hypothetical 30 m resolution satellite image capturing the site. It found that Landsat TM imagery’s ability to retrieve pure or near-pure pixels (90% purity or more) from grassland patches smaller than 1 hectare was limited to 13% success, compared to 52% success when upscaling the resolution to 10 x 10 m pixel size. Additionally, the perimeter/area patch metric is proposed as a predictor for the suitability of the spatial resolution of input imagery. Regression analysis showed that there is a strong negative correlation between a patch’s perimeter/area ratio and its pure pixel potential. The study goes on to characterise the spectral response and discrimination potential for the five main grassland types occurring in the study area: recreational grassland, traditional pasture, modern pasture, fodder production grassland and overgrown grassland. This was done through the construction of spectral response curves, a coincident spectral plot and a contingency matrix as well as by calculating the transformed divergence for the spectral signatures, all based on training samples from the TM imagery. Substantial differences in spectral discrimination potential between imagery from the beginning of the growing season and the middle of summer were found. This is because the spectral responses for these five grassland types converge as the peak of the growing season draws nearer. Recreational grassland shows a consistent discrimination advantage over other grassland types, whereas modern pasture is most easily confused. Traditional pasture land, perhaps the most biologically valuable grassland type, can be spectrally discriminated from other grassland types with satisfactory success rates provided early growing season imagery is used.

Early modes of exegesis : ideal figures in Malachi as a test case

Antikens judiska bibeltolkare hade ett annorlunda sätt att läsa Bibeln än den som moderna läsare är vana vid. Dessa tidiga exegeter tänkte att texten som nu finns i den hebreiska Bibeln, de kristnas Gamla Testamente, är helig ordagrant i den form som den fanns i under deras tid, att den inte innehåller några fel, och att Gud har en övergripande plan gällande helheten, så att man vid behov kan förklara ett Bibelställe med hjälp av ett annat. Dessa antaganden reflekteras i det sätt på vilket antikens exegeter läste och tolkade sin Bibel. Det här ser man då man läser deras texter, från 400-talet före vår tideräknings början till de första århundradena enligt vår tideräkning. Ett verktyg som antikens skrifttolkare ofta använde var den så kallade gezera shava -metoden, där de jämförde identiska ord och fraser i Bibeln för att skänka belysning åt oklara textställen. Hebreiskan, särskilt den ovokaliserade konsonanttexten, innehåller många homonyma ord, alltså ord som ser likadana ut men har olika betydelser. De tidiga exegeterna utnyttjade ofta de möjligheter till alternativa tolkningar som uppstår ur denna tvetydighet. Ibland kunde de dock tvärtom också dra paralleller ur kontextuella likheter, alltid efter behov. I denna avhandling står dessa tidiga anonyma bibeltolkare och deras tolkningar i fokus. Malakis bok, som härstammar från ca år 475 f.v.t., kan ses som ett viktigt tidigt exempel på denna tendens till nytolkning av traditioner. Boken själv har dock också blivit föremål till nytolkningar, redan i de tilläggsverser som finns i dess slut, men särskilt i senare judisk litteratur och i Nya Testamentet. I avhandlingen granskas de fem bibliska gestalter som nämns i Malaki: Jakob, Esau, Levi, Mose och Elia. Hur används de i boken och hur har senare traditioner som anknyter till dem influerats av Malaki? ------------------------------------------------ Antiikin juutalaiset raamatunselittäjät lukivat Raamattua eri tavoin kuin moderni lukija. Heidän näkemyksensä mukaan se teksti, joka nykyään löytyy heprealaisesta Raamatusta eli kristittyjen Vanhasta testamentista, oli pyhä juuri sellaisessa muodossa, jossa se oli heille välittynyt. Se oli virheetön, ja Jumalalla oli siitä kokonaisnäkemys, joka voisi selvitä myös tulkitsijalle, kun tämä vain tutkisi tekstiä riittävän tarkkaan. Nämä perusoletukset näkyvät tavassa, jolla antiikin eksegeetit lukivat ja tulkitsivat Raamattuaan. Se voidaan huomata heidän jälkeensä jättämistään teksteistä, alkaen noin 400-luvulta ennen ajanlaskumme alkua ja jatkuen ajanlaskumme ensimmäisiin vuosisatoihin. Antiikin raamatunselittäjät käyttivät yleisesti muun muassa metodia, joka rabbiinisessa kirjallisuudessa tunnetaan nimellä gezera shava. Raamatussa kahdessa tai useammassa kohtaa esiintyviä samoja sanoja ja ilmauksia verrattiin tällöin toisiinsa ja pyrittiin siten saamaan valaistusta epäselvinä pidettyihin tekstinkohtiin. Heprealle, etenkin sen vokalisoimattomassa muodossa, on tyypillistä homonyymisyys. Samannäköiset sanat voivat eri yhteyksissä tarkoittaa eri asioita. Varhaiset eksegeetit päätyivät usein tästä ilmiöstä nouseviin, keskenään vaihtoehtoisiin tulkintoihin. Toisaalta he saattoivat myös tarvittaessa selittää tekstinkohtaa toisella tekstinkohdalla ainoastaan näiden sisällöllisenkin yhtäläisyyden perusteella. Tässä väitöstutkimuksessa tarkastellaan näitä varhaisia, meille nimettömiksi jääneitä raamatunselittäjiä ja heidän tulkintojaan käyttämällä tutkimuksen lähtökohtana Malakian kirjaa. Malakiaa, joka on peräisin noin vuodelta 475 ennen ajanlaskumme alkua, voidaan pitää yhtenä tärkeimmistä ja varhaisimmista teksteistä, joissa traditioita yhdistellään ja kerrotaan uudelleen edellä mainittuihin perusajatuksiin nojaten ja niihin pohjautuvia menetelmiä käyttäen. Toisaalta Malakian kirjaa on myös tulkittu samojen periaatteiden mukaisesti jo sen myöhemmältä ajalta peräisin olevissa loppujakeissa, ja sittemmin muussa varhaisessa juutalaisessa kirjallisuudessa sekä Uudessa testamentissa. Väitöstutkimuksessa tarkastellaan erityisesti niitä viittä henkilöä, jotka mainitaan Malakian kirjassa: Jaakobia, Esauta, Leeviä, Moosesta ja Eliaa. Kirjoittaja tutkii, miten heidän hahmojaan on käytetty Malakian kirjassa, millaisiin heitä koskeviin traditioihin tämä käyttötapa perustuu, ja missä määrin Malakian kirjan vaikutus on havaittavissa myöhemmässä näihin henkilöihin liitetyssä perinteessä.
