Porvoon maalaiskunnan haja-asutusalueen tiennimet

Kymmenkunta vuotta sitten monessa Suomen kunnassa jouduttiin suureen nimeämistyöhön, kun kuntien keskusjärjestöt suosittivat osoitejärjestelmän luomista myös haja-asutusalueille. Kunnille annetut ohjeet käsittelivät lähinnä osoitejärjestelmän teknistä toteuttamista, eikä nimistönsuunnittelun vaativuutta tajuttu. Tärkein asia eli teiden nimeäminen jäi lähes täysin kunnallisten virkamiesten ja poliitikkojen harkinnan varaan. Varsinkin kaksikielisissä kunnissa jouduttiin hankaluuksiin: tiennimet piti luoda kahdella kielellä, vaikka vanha paikannimistö olisi yksikielistä. Tilannetta mutkisti se, että nimistönsuunnittelun suhtautuminen vanhan paikannimistön kääntämiseen ja mukauttamiseen oli murroksessa juuri osoitteistamisprosessin alussa, eikä uusia periaatteita tuotu selvästi julki ennen 1990-luvun puoliväliä. Vielä 1980-luvulla paikannimien kääntämistä ja mukauttamista suositeltiin, mutta nykyään pidetään jo selvänä, että vanhaa paikannimistöä ei pidä perusteetta muokata vaan sitä voidaan käyttää sellaisenaan. Käypiä nimiä ovat siis niin Kråköntie kuin Koivulavägen. Porvoon maalaiskunnassa nimeämistyö aloitettiin vuonna 1989. Hankkeelle määrättiin virkamiesvalmistelija, joka työskenteli yhdessä toimikunnan kanssa. Tiekunnat saivat ehdottaa teilleen nimiä, ja valtaosaehdotuksista otettiinkin huomioon, mutta alkuvaiheessa lähes kaikki ruotsinkieliset paikannimet käännettiin tai mukautettiin. Koska toimikunnan jäsenillä ei ollut asiantuntemusta, nimien käännökset olivat usein epäonnistuneita ja oikeinkirjoitus horjui. Nähtävilläolon jälkeen alkuvuonna 1991 toimikunta päätti turvautua Kotimaisten kielten tutkimuskeskuksen apuun. Tiekunnat eivät hyväksyneet käännöksiä ja mukaelmia, joten ne neuvojen jälkeen poistettiin. Myöhemmin käännökset palautettiin luontonimiin perustuviin tiennimiin, mutta suurimmalta osalta vanha nimistö säilyi muuttamattomana. Emmintöjen jälkeen kunnanhallitus hyväksyi nimistön syksyllä 1995. Suurin osa Porvoon maalaiskunnan 790:stä haja-asutusalueen tiennimestä perustuu vanhaan paikannimistöön (81 %) tai on muuten paikkaan liittyvää (15 %). Vain pieni osa nimistä (4 %) on harkinnaisia.Vanhaan paikannimistöön perustuvissa tiennimissä on eniten tilannimen (41 %), maastonimen (26 %) ja kylännimen (14 %) sisältäviä nimiä. Yleisimmät jälkiosat ovat tie (86 %), kuja (5 %) ja polku (5 %). Määriteosaltaan tyystin suomenkielisiä nimipareista on 14 % (Aholantie-Aholavägen) ja ruotsinkielisiä 36 % (Bodöntie-Bodövägen). Tiekuntien nimet ja uudet tiennimet ovat eri asioita, mutta noin kolmannes uusista tiennimistä sisältää tiekunnan nimessä esiintyvän nimen. Näin Porvoon maalaiskunnan tiekuntien nimissä esiintyvistä 252 määriteosasta 193:a (77 %) on hyödynnetty 245 uudessa tiennimessä. Ennen tiennimiä osoitteissa käytettiin yleensä vain postinumeroa ja postitoimipaikkaa. Jonkin verran käytössä oli myös osoitenimiä (esim. Björkebo, Kappeli). Niistäkin valtaosa (73 %) esiintyy uusissa tiennimissä. Laskelma pohjautuu postin osoitetietojärjestelmään. Uusi tiennimistö perustuu usein jo käytössä oleviin tien- ja paikannimiin, joten se ei uhkaa vanhan nimistön asemaa. Uuden nimistön vaikutusta vähentää sekin, että sitä tarvitsevat lähinnä ulkopuoliset. Kotitienoot hahmotetaan edelleenkin vanhojen ja vakiintuneiden paikannimien avulla, mutta toki uudet tiennimet tuovat esiin monia vähän käytettyjä paikannimiä ja tarjoavat mainion katsauksen seudun kulttuuriperintöön. Ei siis ole samantekevää, miten teitä nimetään. Huonoiksi koetut uudet nimet eivät välttämättä edes vakiinnu käyttöön. Porvoon maalaiskunnan tulosten vertaaminen koko Suomen kattavaan materiaaliin osoittaa hankkeen edenneen hitaasti, mutta kaksikielisyyden ja työvoiman vähyyden huomioon ottaen kohtalaisesti. Vertailu kuuden muun uusmaalaisen kunnan kanssa paljastaa eroja paitsi hankkeen toteuttamistavoissa myös työn tuloksessa eli nimistössä. Yleensä tiekunnat ja asukkaat ovat saaneet tehdä ehdotuksia ja nimistön ovat laatineet virkamiehet ja nimitoimikunnat ilman palkattua asiantuntijaa. Kotimaisten kielten tutkimuskeskuksen puoleen on sentään käännytty. Tärkeä havainto on se, että kaksikieliset kunnat ovat halunneet vaalia kulttuuriarvoja ja säilyttää keskeisen vanhan paikannimistönsä koskemattomana.

Representing the epistemic nature of teachers’ practical knowledge : The case of class teachers’ general pedagogy

The present study addressed the epistemology of teachers’ practical knowledge. Drawing from the literature, teachers’ practical knowledge is defined as all teachers’ cognitions (e.g., beliefs, values, motives, procedural knowing, and declarative knowledge) that guide their practice of teaching. The teachers’ reasoning that lies behind their practical knowledge is addressed to gain insight into its epistemic nature. I studied six class teachers’ practical knowledge; they teach in the metropolitan region of Helsinki. Relying on the assumptions of the phenomenographic inquiry, I collected and analyzed the data. I analyzed the data in two stages where the first stage involved an abductive procedure, and the second stage an inductive procedure for interpretation, and thus developed the system of categories. In the end, a quantitative analysis nested into the qualitative findings to study the patterns of the teachers’’ reasoning. The results indicated that teachers justified their practical knowledge based on morality and efficiency of action; efficiency of action was found to be presented in two different ways: authentic efficiency and naïve efficiency. The epistemic weight of morality was embedded in what I call “moral care”. The core intention of teachers in the moral care was the commitment that they felt about the “whole character” of students. From this perspective the “dignity” and the moral character of the students should not replaced for any other “instrumental price”. “Caring pedagogy” was the epistemic value of teachers’ reasoning in the authentic efficiency. The central idea in the caring pedagogy was teachers’ intentions to improve the “intellectual properties” of “all or most” of the students using “flexible” and “diverse” pedagogies. However, “regulating pedagogy” was the epistemic condition of practice in the cases corresponding to naïve efficiency. Teachers argued that an effective practical knowledge should regulate and manage the classroom activities, but the targets of the practical knowledge were mainly other “issues “or a certain percentage of the students. In these cases, the teachers’ arguments were mainly based on the notion of “what worked” regardless of reflecting on “what did not work”. Drawing from the theoretical background and the data, teachers’ practical knowledge calls for “praxial knowledge” when they used the epistemic conditions of “caring pedagogy” and “moral care”. It however calls for “practicable” epistemic status when teachers use the epistemic condition of regulating pedagogy. As such, praxial knowledge with the dimensions of caring pedagogy and moral care represents the “normative” perspective on teachers’ practical knowledge, and thus reflects a higher epistemic status in comparison to “practicable” knowledge, which represents a “descriptive” perception toward teachers’ practical knowledge and teaching.

Perspectives on prescribing in nursing homes in Helsinki

Prescribing for older patients is challenging. The prevalence of diseases increases with advancing age and causes extensive drug use. Impairments in cognitive, sensory, social and physical functioning, multimorbidity and comorbidities, as well as age-related changes in pharmacokinetics and pharmacodynamics all add to the complexity of prescribing. This study is a cross-sectional assessment of all long-term residents aged ≥ 65 years in all nursing homes in Helsinki, Finland. The residents’ health status was assessed and data on their demographic factors, health and medications were collected from their medical records in February 2003. This study assesses some essential issues in prescribing for older people: psychotropic drugs (Paper I), laxatives (Paper II), vitamin D and calcium supplements (Paper III), potentially inappropriate drugs for older adults (PIDs) and drug-drug interactions (DDIs)(Paper IV), as well as prescribing in public and private nursing homes. A resident was classified as a medication user if his or her medication record indicated a regular sequence for its dosage. Others were classified as non-users. Mini Nutritional Assessment (MNA) was used to assess residents’ nutritional status, Beers 2003 criteria to assess the use of PIDs, and the Swedish, Finnish, INteraction X-referencing database (SFINX) to evaluate their exposure to DDIs. Of all nursing home residents in Helsinki, 82% (n=1987) participated in studies I, II, and IV and 87% (n=2114) participated in the study III. The residents’ mean age was 84 years, 81% were female, and 70% were diagnosed with dementia. The mean number of drugs was 7.9 per resident; 40% of the residents used ≥ 9 drugs per day, and were thus exposed to polypharmacy. Eighty percent of the residents received psychotropics; 43% received antipsychotics, and 45% used antidepressants. Anxiolytics were prescribed to 26%, and hypnotics to 28% of the residents. Of those residents diagnosed with dementia, 11% received antidementia drugs. Fifty five percent of the residents used laxatives regularly. In multivariate analysis, those factors associated with regular laxative use were advanced age, immobility, poor nutritional status, chewing problems, Parkinson’s disease, and a high number of drugs. Eating snacks between meals was associated with lower risk for laxative use. Of all participants, 33% received vitamin D supplementation, 28% received calcium supplementation, and 20% received both vitamin D and calcium. The dosage of vitamin D was rather low: 21% received vitamin D 400 IU (10 µg) or more, and only 4% received 800 IU (20 µg) or more. In multivariate analysis, residents who received vitamin D supplementation enjoyed better nutritional status, ate snacks between meals, suffered no constipation, and received regular weight monitoring. Those residents receiving PIDs (34% of all residents) more often used psychotropic medication and were more often exposed to polypharmacy than residents receiving no PIDs. Residents receiving PIDs were less often diagnosed with dementia than were residents receiving no PIDs. The three most prevalent PIDs were short-acting benzodiazepine in greater dosages than recommended, hydroxyzine, and nitrofurantoin. These three drugs accounted for nearly 77% of all PID use. Of all residents, less than 5% were susceptible to a clinically significant DDI. The most common DDIs were related to the use of potassium-sparing diuretics, carbamazepine, and codeine. Residents exposed to potential DDIs were younger, had more often suffered a previous stroke, more often used psychotropics, and were more often exposed to PIDs and polypharmacy than were residents not exposed to DDIs. Residents in private nursing homes were less often exposed to polypharmacy than were residents in public nursing homes. Long-term residents in nursing homes in Helsinki use, on average, nearly eight drugs daily. The use of psychotropic drugs in our study was notably more common than in international studies. The prevalence of laxatives equaled other prior international studies. Regardless of the known benefit and recommendation of vitamin D supplementation for elderly residing mostly indoors, the proportion of nursing home residents receiving vitamin D and calcium was surprisingly low. The use of PIDs was common among nursing home residents. PIDs increased the likelihood of DDIs. However, DDIs did not seem a major concern among the nursing home population. Monitoring PIDs and potential drug interactions could improve the quality of prescribing.

Community forestry and environmental literacy in northern Thailand : Towards collaborative natural resource management and conservation

Conservation and sustainable management of tropical forests needs a holistic approach: in addition to ecological concerns, socio-economic issues including cultural aspects must be taken into consideration. An ability to adapt practices is a key to successful collaborative natural resource management. Achieving this requires local participation and understanding of local conceptions of the environment. This study examined these issues in the context of northern Thailand. Northern uplands are the home of much of the remaining natural forest in Thailand and several ethnic minority groups commonly referred to as hill tribes. The overall purpose of this study was to grasp a regional view of an ethnically diverse forested area and to elicit prospects to develop community forestry for conservation purposes and for securing people s livelihood. Conservation was a central goal of management as the forests in the area were largely designated as protected. The aim was to study local perceptions, objectives, values and practices of forest management, under the umbrella of the concept environmental literacy, as well as the effects of forest policy on community management goals and activities. Environmental literacy refers to holistic understanding of the environment. It was used as a tool to examine people s views, interests, knowledge and motivation associated to forests. The material for this study was gathered in six villages in Chiang Mai Province. Three minority groups were included in the study, the Karen, Hmong and Lawa, and also the Thai. Household and focus group interviews were conducted in the villages. In addition, officials at district, regional and national levels, workers of non-governmental organisations, and academics were interviewed, and some data were gathered from the students of a local school. The results showed that motivation for protecting the forests existed among each ethnic group studied. This was a result of culture and traditions evolved in the forest environment but also of a need to adapt to a changed situation and environment and to outside pressures. The consequences of deforestation were widely agreed on in the villages, and the impact of socio-economic changes on the forests and livelihood was also recognised. The forest was regarded as a source of livelihood providing land, products and services essential to the people inhabiting rural uplands. Traditions, fire control, cooperation, reforestation, separation of protected and utilisable areas, and rules were viewed as central for conservation. For the villagers, however, conservation meant sustainable use, whereas the government has tended to prefer strict restrictions on forest resource use. Thus, conflicts had arisen. Between communities, cooperation was more dominant than conflict. The results indicated that the heterogeneity of forest dwellers, although it has to be recognised, should not be overemphasised: ethnic diversity can be considered as no major obstacle for successful community forestry. Collaborative management is particularly important in protected areas in order to meet the conservation goals while providing opportunities for livelihood. Forest management needs more positive incentives and increased dialogue.

Stretching single DNA-molecules with temperature-stabilized optical tweezers

This thesis consists of two parts; in the first part we performed a single-molecule force extension measurement with 10kb long DNA-molecules from phage-λ to validate the calibration and single-molecule capability of our optical tweezers instrument. Fitting the worm-like chain interpolation formula to the data revealed that ca. 71% of the DNA tethers featured a contour length within ±15% of the expected value (3.38 µm). Only 25% of the found DNA had a persistence length between 30 and 60 nm. The correct value should be within 40 to 60 nm. In the second part we designed and built a precise temperature controller to remove thermal fluctuations that cause drifting of the optical trap. The controller uses feed-forward and PID (proportional-integral-derivative) feedback to achieve 1.58 mK precision and 0.3 K absolute accuracy. During a 5 min test run it reduced drifting of the trap from 1.4 nm/min in open-loop to 0.6 nm/min in closed-loop.

Salaisen evankelistan salaliitto : Uusin keskustelu Klemens Aleksandrialaisen kirjeestä Theodorokselle

This thesis is an assessment of the hoax hypothesis, mainly propagated in Stephen C. Carlson's 2005 monograph "The Gospel Hoax: Morton Smith's Invention of Secret Mark", which suggests that professor Morton Smith (1915-1991) forged Clement of Alexandria's letter to Theodore. This letter Smith claimed to have discovered as an 18th century copy in the monastery of Mar Saba in 1958. The Introduction narrates the discovery story of Morton Smith and traces the manuscript's whereabouts up to its apparent disappearance in 1990 following with a brief history of scholarship of the MS and some methodological considerations. Chapters 2 and 3 deal with the arguments for the hoax (mainly by Stephen C. Carlson) and against it (mainly Scott G. Brown). Chapter 2 looks at the MS in its physical aspects, and chapter 3 assesses its subject matter. I conclude that some of the details fit reasonably well with the hoax hypothesis, but on the whole the arguments against it are more persuasive. Especially Carlson's use of QDE-analysis (Questioned Document Examination) has many problems. Comparing the handwriting of Clement's letter to Morton Smith's handwriting I conclude that there are some "repeated differences" between them suggesting that Smith is not the writer of the disputed letter. Clement's letter to Theodore derives most likely from antiquity though the exact details of its character are not discussed in length in this thesis. In Chapter 4 I take a special look at Stephen C. Carlson's arguments which propose that Morton Smith hid clues of his identity to the MS and the materials surrounding it. Comparing these alleged clues to known pseudoscientific works I conclude that Carlson utilizes here methods normally reserved for building a conspiracy theory; thus Carlson's hoax hypothesis has serious methodological flaws in respect to these hidden clues. I construct a model of these questionable methods titled "a boisterous pseudohistorical method" that contains three parts: 1) beginning with a question that from the beginning implicitly contains the answer, 2) considering everything will do as evidence for the conspiracy theory, and 3) abandoning probability and thinking literally that everything is connected. I propose that Stephen C. Carlson utilizes these pseudoscientific methods in his unearthing of Morton Smith's "clues". Chapter 5 looks briefly at the literary genre I title "textual puzzle -thriller". Because even biblical scholarship follows the signs of the times, I propose Carlson's hoax hypothesis has its literary equivalents in fiction in titles like Dan Brown's "Da Vinci Code" and in academic works in titles like John Dart's "Decoding Mark". All of these are interested in solving textual puzzles, even though the methodological choices are not acceptable for scholarship. Thus the hoax hypothesis as a whole is alternatively either unpersuasive or plain bad science.

Reinhold Niebuhrin syntikäsitys

Reinhold Niebuhrin syntikäsitys rakentuu hänen ihmiskäsitykseensä kuuluvan dikotomian henki-luonto, sekä sitä sisällöllisesti vastaavan käsiteparin vapaus-rajallisuus, varaan. Ihmisen hengen kykyjä ovat transsendenssi yli luonnon, itsetranssendenssi sekä vapaus. Toisaalta ihminen on luontonsa kautta sidottu elollisen luonnon rajallisuuteen, vajavaisuuteen ja kuolevaisuuteen. Ihmisen rajallisuus on hengen kykyjen tavoin Jumalan luomisessa ihmiselle antama ominaisuus, ja siksi hyvä. Ihmisen asema rajallisena ja vapaana, eli ihmisen ristiriita antaa hänelle aiheen synnin tekemiseen. Tämä ihmisen ristiriita ei kuitenkaan ole synnin syy. Ihmisen asema luonnon ja hengen rajapinnassa saa hänet levottomaksi. Levottomuus on ihmisen ristiriidan väistämätön seuralainen ja samalla synnin sisäinen ennakkoehto. Raamatun lankeemuskertomus on Niebuhrin mukaan myytti, joka kuvaa symbolisesti ihmisen lankeamista syntiin. Lankeemusmyyttiä ei pidä tulkita kirjaimellisesti eikä kausaalisesti, sillä tällöin se menettää todellisen merkityksensä. Lankeemusmyytin mukaan ihmisen pahaa edeltää pahan voima, eli paholainen. Koska paholainen lankesi ennen ihmistä, ihmisen synti ei seuraa väistämättä ihmisen tilanteesta vapaana ja rajallisena. Ihmisen synti ei myöskään ole silkkaa perverssiyttä, tietoista pahan tekemistä ja Jumalan vastaista uhmaa. Ihmisen vapaus ja rajallisuus muuttuvat kiusaukseksi vasta, kun ne on tulkittu väärin. Ihmisen tekoa edeltävä pahan voima ehdottaa tätä tulkintaa ihmiselle. Niebuhr kuvaa Kierkegaardilta lainaamillaan ilmauksilla, kuinka 'synti asettaa itsensä' ja 'synti edellyttää itsensä'. Hän puhuu myös 'synnin laadullisesta hypystä'. Syntiä ei koskaan voi johtaa tietystä tilanteesta nousevasta kiusauksesta. Itsensä asettava synti on ihmisen oma synti. Synti edellyttää itsensä tarkoittaa, että kaikkea syntiä edeltää epäuskon synti. Ilman epäuskoa ihmisen levottomuus ei johtaisi syntiin. Niebuhrin metodinen tukeutuminen Kierkegaardiin ei ole johdonmukaista, mistä osittain johtuu, että hänen käsityksensä ihmisen syntiin lankeamisesta on ristiriitainen. Niebuhr sotkee myytti- ja historiapuheen keskenään. Ihmisen tietoisuus ja vapaus ovat edellytys sille, että ihminen ylipäänsä voi tehdä syntiä. Niebuhr torjuu perinteisen kristillisen näkemyksen, jonka mukaan lankeemus merkitsi radikaalia muutosta ihmisen tahdon vapauteen. Ihmisen huomio, ettei hän kykene tekemään valintaa hyvän ja pahan välillä, on Niebuhrin mukaan merkittävin osoitus ihmisen vapaudesta. Ihmisen tietoisuus synnistään ei koskaan ole täydellistä. Ihminen ei tee syntiä täysin tietoisesti ja harkitusti. Toisaalta ihmisen osittainen tietämättömyys synnistään on synnin seuraus. Voidakseen jatkaa synnin tekemistä, eli voidakseen pitäytyä kohtuuttomassa itserakkaudessaan, ihmisen on petettävä ensin itseään, sitten toisia ihmisiä. Niebuhr määrittelee hyvin pidättyväisesti näkemyksensä perisynnistä. Perisynti on ennen kaikkea ihmisen taipumus synnin tekemiseen. Synti on peräisin ihmisen tahdon viasta. Toisaalta Niebuhrin mukaan ihminen tekee väistämättä syntiä. Niebuhr on muutamissa yhteyksissä varovaisesti sillä kannalla, että ihmisen luonto on synnin seurauksena turmeltunut. Toisissa yhteyksissä hän torjuu tällaisen näkemyksen. Niebuhrin näkemys synnin väistämättömyydestä sekä näkemys ihmisen tahdon viasta jäävät jossain määrin irrallisiksi osiksi hänen ihmiskäsityksessään. Ihmisen synti on ylpeyttä ja aistillisuutta. Ihmisellä on taipumus kieltää joko rajallisuutensa tai vapautensa. Kieltäessään rajallisuutensa hän lankeaa ylpeyteen. Kieltäessään vapautensa hän lankeaa aistillisuuteen. Ylpeyden muotoja on neljä: vallanylpeys, tiedonylpeys, moraalinen ylpeys ja hengellinen ylpeys. Aistillisuudessa on kolme vaihetta. Aistillisuus on itserakkautta, yritystä paeta itseä toiseen ihmiseen tai luontoon sekä kolmanneksi pakoa tyhjyyteen ja tiedostamattomuuteen. Synti ja syyllisyys liittyvät väistämättä seksiin. Seksi on aistillisuuden elävin ilmaus ja samalla ihmisen luovuuden kliimaksi. Niebuhr pitää ihmisyhteisöjä yksilöiden ohella rajallisessa mielessä synnin subjekteina. Yhteisöillä on yksilöiden tavoin henki ja luonto, sekä itsetranssendenssin elimiä. Niebuhr pitää yhteisöjä yksilöitä moraalisesti pahempina. Yhteisöt aiheuttavat yksilöitä enemmän objektiivista pahaa. Niebuhr kritisoi syntikäsityksensä pohjalta liberalismiksi kutsumaansa ajattelua. Liberalismin perustana on Niebuhrin mukaan kehityksen idea, joka on perusteetonta optimistista uskoa täydellistyvään maailmaan ja uskoa historiaan itsensä lunastavana prosessina. Niebuhrin mukaan kaikki vallankäyttö elämässä johtaa sortoon ja epäoikeudenmukaisuuteen. Sen vuoksi yhteisöjä on hallittava voimien balanssilla sekä hallituksella. Nämä tekijät on mahdollista ottaa pätevästi huomioon vain demokratiassa. Niebuhr näkee kirkon silkkana ihmisyhteisönä, jolle on kuitenkin suotu evankeliumi. Hän korostaa kirkon syntisyyttä, muttei ollenkaan sen pyhyyttä.

Strategic Information Acquisition: Applications to Herding and Auctions

The information that the economic agents have and regard relevant to their decision making is often assumed to be exogenous in economics. It is assumed that the agents either poses or can observe the payoff relevant information without having to exert any effort to acquire it. In this thesis we relax the assumption of ex-ante fixed information structure and study what happens to the equilibrium behavior when the agents must also decide what information to acquire and when to acquire it. This thesis addresses this question in the two essays on herding and two essays on auction theory. In the first two essays, that are joint work with Klaus Kultti, we study herding models where it is costly to acquire information on the actions that the preceding agents have taken. In our model the agents have to decide both the action that they take and additionally the information that they want to acquire by observing their predecessors. We characterize the equilibrium behavior when the decision to observe preceding agents' actions is endogenous and show how the equilibrium outcome may differ from the standard model, where all preceding agents actions are assumed to be observable. In the latter part of this thesis we study two dynamic auctions: the English and the Dutch auction. We consider a situation where bidder(s) are uninformed about their valuations for the object that is put up for sale and they may acquire this information for a small cost at any point during the auction. We study the case of independent private valuations. In the third essay of the thesis we characterize the equilibrium behavior in an English auction when there are informed and uninformed bidders. We show that the informed bidder may jump bid and signal to the uninformed that he has a high valuation, thus deterring the uninformed from acquiring information and staying in the auction. The uninformed optimally acquires information once the price has passed a particular threshold and the informed has not signalled that his valuation is high. In addition, we provide an example of an information structure where the informed bidder initially waits and then makes multiple jumps. In the fourth essay of this thesis we study the Dutch auction. We consider two cases where all bidders are all initially uninformed. In the first case the information acquisition cost is the same across all bidders and in the second also the cost of information acquisition is independently distributed and private information to the bidders. We characterize a mixed strategy equilibrium in the first and a pure strategy equilibrium in the second case. In addition we provide a conjecture of an equilibrium in an asymmetric situation where there is one informed and one uninformed bidder. We compare the revenues that the first price auction and the Dutch auction generate and we find that under some circumstances the Dutch auction outperforms the first price sealed bid auction. The usual first price sealed bid auction and the Dutch auction are strategically equivalent. However, this equivalence breaks down in case information is acquired during the auction.

Essays on macroeconomic effects of fiscal policy rules

Economic and Monetary Union can be characterised as a complicated set of legislation and institutions governing monetary and fiscal responsibilities. The measures of fiscal responsibility are to be guided by the Stability and Growth Pact, which sets rules for fiscal policy and makes a discretionary fiscal policy virtually impossible. To analyse the effects of the fiscal and monetary policy mix, we modified the New Keynesian framework to allow for supply effects of fiscal policy. We show that defining a supply-side channel for fiscal policy using an endogenous output gap changes the stabilising properties of monetary policy rules. The stability conditions are affected by fiscal policy, so that the dichotomy between active (passive) monetary policy and passive (active) fiscal policy as stabilising regimes does not hold, and it is possible to have an active monetary - active fiscal policy regime consistent with dynamical stability of the economy. We show that, if we take supply-side effects into ac-count, we get more persistent inflation and output reactions. We also show that the dichotomy does not hold for a variety of different fiscal policy rules based on government debt and budget deficit, using the tax smoothing hypothesis and formulating the tax rules as difference equations. The debt rule with active monetary policy results in indeterminacy, while the deficit rule produces a determinate solution with active monetary policy, even with active fiscal policy. The combination of fiscal requirements in a rule results in cyclical responses to shocks. The amplitude of the cycle is larger with more weight on debt than on deficit. Combining optimised monetary policy with fiscal policy rules means that, under a discretionary monetary policy, the fiscal policy regime affects the size of the inflation bias. We also show that commitment to an optimal monetary policy not only corrects the inflation bias but also increases the persistence of output reactions. With fiscal policy rules based on the deficit we can retain the tax smoothing hypothesis also in a sticky price model.

Obstetric and gynaecological aspects of HIV infection

The purpose of the present study was to examine the outcome of pregnancies among HIV-infected women in Helsinki, use of the levonorgestrel-releasing intrauterine system (LNG-IUS) among HIV-infected women and the prevalence and risk factors of cytological and histologically proven cervical lesions in this population. Between 1993 and 2003 a total of 45 HIV-infected women delivered 52 singleton infants. HIV infection was diagnosed during pregnancy in 40% of the mothers. Seventeen of the mothers received antiretroviral (ARV) medication prior to pregnancy and in 34 cases, the medication was started during pregnancy. A good virological response (i.e. HIV RNA load <1000/mL during the last trimester) to ARV medication was achieved in 36/40 (90%) of the patients in whom HI viral load measurements were performed. Of the infants, 92% were born at term, and their mean (±SD) birth weight was 3350±395 g. The Caesarean section rate was low, 25%. All newborns received ARV medication and none of the infants born to mothers with pre-delivery diagnosis of maternal HIV infection were infected. The safety and advantages of the LNG-IUS were studied prospectively (n=12) and retrospectively (n=6). The LNG-IUS was well tolerated and no cases of PID or pregnancy were noted. Menstrual bleeding was reduced significantly during use of the LNG-IUS; this was associated with a slight increase in haemoglobin levels. Serum oestradiol concentrations remained in the follicular range in all subjects. The key finding was that genital shedding of HIV RNA did not change after the insertion of the LNG-IUS. The mean annual prevalence of low-grade squamous intraepithelial lesions (SIL) was 15% and that of high-grade SIL was 5% among 108 systematically followed HIV-infected women during 1989 2003. A reduced CD4 lymphocyte count was associated with an increased prevalence of SIL, whereas duration of HIV infection, use of ARV medication and HI viral load were not. The cumulative risk of any type of SIL was 17% after one year and 48% after five years among patients with initially normal Pap smears. The risk of developing SIL was associated with young age and a high initial HI viral load. During the follow-up 51 subjects (n=153) displayed cervical intraepithelial neoplasia (CIN), (16% CIN1 and 18% CIN 2-3). Only one case of cancer of the uterine cervix was detected. Pap smears were reliable in screening for CIN. Both nulliparity (p<0.01) and bacterial vaginosis (p<0.04) emerged as significant risk factors of CIN. In conclusion, a combination of universal antenatal screening and multidisciplinary management allows individualized treatment and prevents vertical transmission of HIV. Use of the LNG-IUS is safe among HIV-infected women and cervicovaginal shedding of HIV RNA is not affected by use of the LNG-IUS. The risk of cervical pre-malignant lesions is high among HIV-infected women despite systematic follow-up.

Pitfalls in the Treatment of Persons with Dementia

Pitfalls in the treatment of persons with dementia Persons with dementia require high-quality health care, rehabilitation and sufficient social services to support their autonomy and to postpone permanent institutionalization. This study sought to investigate possible pitfalls in the care of patients with dementia: hip fracture rehabilitation, use of inappropriate or antipsychotic medication, social and medicolegal services offered to dementia caregiving families. Three different Finnish samples were used from years 1999-2005, mean age 78 to 86 years. After hip fracture operation, the weight-bearing restriction especially in group of patients with dementia, was associated with a longer rehabilitation period (73.5 days vs. 45.5 days, p=0.03) and the inability to learn to walk after six weeks (p<0.001). Almost half (44%) of the pre-surgery home-dwellers with dementia in our sample required permanent hospitalization after hip fracture. Potentially inappropriate medication was used among 36.2% of nursing home and hospital patients. The most common PIDs in Finland were temazepam over 15 mg/day, oxybutynin, and dipyridamole. However, PID use failed to predict mortality or the use of health services. Nearly half (48.4%) of the nursing home and hospital patients with dementia used antipsychotic medication. The two-year mortality did not differ among the users of conventional or atypical antipsychotics or the non-users (45.3% vs.32.1% vs.49.6%, p=0.195). The mean number of hospital admissions was highest among non-users (p=0.029). A high number of medications (HR 1.12, p<0.001) and the use of physical restraints (HR 1.72, p=0.034) predicted higher mortality at two years, while the use of atypical antipsychotics (HR 0.49, p=0.047) showed a protective effect, if any. The services most often offered to caregiving families of persons with Alzheimer s disease (AD) included financial support from the community (36%), technical devices (33%), physiotherapy (32%), and respite care in nursing homes (31%). Those services most often needed included physiotherapy for the spouse with dementia (56%), financial support (50%), house cleaning (41%), and home respite (40%). Only a third of the caregivers were satisfied with these services, and 69% felt unable to influence the range of services offered. The use of legal guardians was quite rare (only 4.3%), while the use of financial powers of attorney was 37.8%. Almost half (47.9%) of the couples expressed an unmet need for discussion with their doctor about medico-legal issues, while only 9.9% stated that their doctor had informed them of such matters. Although we already have many practical methods to develop the medical and social care of persons with AD, these patients and their families require better planning and tailoring of such services. In this way, society could offer these elderly persons better quality of life while economizing on its financial resources. This study was supported by Social Insurance Institution of Finland and part of it made in cooperation with the The Central Union of the Welfare for the Aged, Finland.

Paganism, Traditionalism, Nationalism : Narratives of Russian Rodnoverie

The topic of this dissertation is Rodnoverie, a religion that revives pre-Christian Slavic spirituality. Rodnoverie has been noted to be one of the fastest growing new religions in Russia and the aim of the study is to analyse why and how the movement has attained its popularity. First, the analysis asks how Rodnovers themselves explain the revival of ancient Paganism at this particular historical moment. Secondly, these interpretations are reflected in the framework of sociological discussions about contemporary religiosity. The analysis discusses how the Rodnoverie movement corresponds to some tendencies that are considered to characterise late modern religiosity. The primary material of the research is Rodnoverie texts: books, newspapers and electronic articles. The published literature is supplemented by fieldwork material which includes interviews with some Rodnoverie leaders and the author s participant observation of rituals and gatherings. Methodologically, the study draws on a sociological narrative approach that is focused on examining how individuals and groups use narratives to construct their identities and to challenge mainstream discussions and interpretations. The analysis discerns three narratives. The first one of these portrays Rodnoverie as a revival of the native Russian or Slavic religion. The narrative provides a new version of the old Slavophile idea, according to which imitation of the West has misguided Russia and, therefore, Russians should turn to their own tradition. In the second narrative, Rodnoverie is presented as a nature religion that features tolerance and pluralistic values. According to these perceptions, the emergence of Rodnoverie marks the dead-end of the earlier hegemonic universalistic world-views, the mono-ideologies . While the nationalist narrative focuses on Russia s national heritage, the third narrative interprets the tradition in more universal terms as an alternative to modern values and way of life. The main argument of this narrative is that contemporary people have become alienated from nature, their roots and their community. The themes that are discussed in the theoretical literature on late modern religiosity often configure in Rodnovers interpretations either directly or when looked at through an analytical framework. Of the various themes that are addressed in a sociological study of religion the ones that have most relevance for Rodnoverie are the discussions on individualisation, globalisation and secularisation. Rodnoverie reflects such tendencies as the subjectivisation of religion and the modern crisis of authority. The movement also both exemplifies and actively promotes religious pluralisation in Russia.

Koodinvaihto Madventures-matkailuohjelmassa

Pro gradu tutkielman aiheena on kielensisäinen koodinvaihto suomalaisessa Madventures-matkailuohjelmassa. Tutkielman tavoitteena on selvittää, mitä funktioita koodinvaihdolla on kyseisessä ohjelmassa ja millä tavoin koodinvaihto siinä ilmenee. Aineistona on ohjelman ensimmäinen tuotantokausi, joka on kuvattu vuonna 2002. Tuotantokausi koostuu kymmenestä 45 50 minuuttia pitkästä jaksosta. Tarkasteltavana on ohjelman kahden juontajan, Riku Rantalan ja Tuomas Tunna Milonoffin kieli. Tutkielmassa hyödynnettävät tutkimussuuntaukset ovat sosiolingvistinen variaationtutkimus ja keskustelunanalyysi. Analyysiluvut rakentuvat koodinvaihdon funktioiden mukaan. Luvussa 3 tarkastellaan koodinvaihtoja, jotka viestivät siirtymästä roolista toiseen. Koodinvaihdon funktiona voi tällöin olla aikaisemman, todella tapahtuneen tai sellaisena esitetyn puhetilanteen referointi, kuvitteellisen puhetilanteen esittäminen tai ohjelman juontajan rooliin orientoituminen. Luvussa 4 käsitellään koodinvaihtoa merkkinä siirtymästä näkökulmasta toiseen. Vaihtelevina näkökulmina voivat tällöin olla persoonallinen ja objektiivinen, nykyinen ja mennyt aika tai puhujan ja katsojan näkökulma. Luku 5 on sekaluku, johon on koottu muita aineistossani esiintyviä koodinvaihdon funktioita. Niitä ovat moodinvaihto, vuoron vastaanottajan vaihtuminen, siirtyminen toiminnasta toiseen, edeltävän käskyn vahvistaminen tai sen ilmaiseminen, ettei sanottu asia pidä paikkaansa. Useilla koodinvaihdoilla on samaan aikaan monia eri funktioita. Esimerkiksi kuvitteellisen puhetilanteen referointiin liittyy aina myös moodinvaihto vakavasta humoristiseen. Enemmistö koodinvaihdoista tapahtuu pääkaupunkiseudun puhekielen ja yleiskielen välillä. Jonkin verran koodinvaihtoa tapahtuu myös murteelliseen koodiin tai toiseen kielelliseen tyyliin. Tavallisesti puhujat osoittavat orientoituvansa toiseen koodiin paralingvistisillä piirteillä mutta myös muilla ei-kielellisillä keinoilla kuten ilmeillä ja eleillä. Paralingvististen piirteiden esiintyminen vaihtelee jossain määrin koodinvaihdon funktioiden mukaan. Silloin kun koodinvaihdon funktiona on referointi tai siirtyminen katsojan näkökulmaan, koodinvaihdon yhteydessä esiintyy usein äänenlaadun muutoksia sekä muusta puheesta poikkeavaa prosodiaa. Muissa funktiossa niitä esiintyy harvemmin. Koodinvaihto ilmenee toisinaan myös lauserakenteessa, erityisesti viestiessään näkökulman muutoksesta. Erikoinen piirre tämän tutkielman koodinvaihdoissa on se, ettei koodinvaihto aina koske sanastoa. Vaikka äänne- ja muotopiirteet ovatkin yleiskielisiä, voi koodinvaihtojakson sanasto siitä huolimatta olla slangipitoista. Runsas slangisanasto onkin Madventuresin kielelle kaikkein ominaisin piirre. Koodinvaihdossa on useimmiten olennaisempaa kontrasti kahden eri kielimuodon välillä kuin se, mihin kielimuotoon koodi vaihtuu. Tällöin koodinvaihdon funktio on sama riippumatta siitä, vaihtuuko koodi pääkaupunkiseudun puhekielestä yleiskieleen vai esimerkiksi murteeseen. Tietyissä funktioissa koodinvaihtojakson kielimuodolla on kuitenkin merkitystä funktion kannalta. Esimerkiksi ohjelman juontajan rooliin siirryttäessä koodi vaihtuu poikkeuksetta pääkaupunkiseudun puhekielestä yleiskieleen. Sen sijaan esimerkiksi referoitaessa kielimuodolla ei ole juuri merkitystä funktion kannalta, vaan referaateissa esiintyy useita eri kielimuotoja. Ohjelman juontajat eivät vaihda koodia samalla tavalla, vaan heidän koodinvaihtotavoissaan on eroja. Riku vaihtaa aineistossa koodia selvästi useammin kuin Tunna. Lisäksi hän käyttää koodinvaihtoa useammissa funktioissa ja hyödyntää koodinvaihdossa useita eri kielimuotoja. Sen sijaan Tunnan koodinvaihdot rajoittuvat lähes yksinomaan pääkaupunkiseudun puhekielen ja yleiskielen välille.
