Suomen Taideyhdistyksestä Ateneumiin : Fredrik Cygnaeus, Carl Gustaf Estlander ja taidekokoelman roolit

From the Finnish Art Society to the Ateneum: Fredrik Cygnaeus, Carl Gustaf Estlander and the Roles of the Art Collection My dissertation deals with the Finnish Art Society and the development of its collection in the evolving field of the visual arts from the foundation of the society in 1846 to its exhibition in the Ateneum, a palace of art that was opened to the public in Helsinki in 1888. The main questions that it addresses are why and how the collection came into being, what its purpose was and what kind of future prospects were projected for it in the rapidly evolving field of the visual arts. I have examined the subject of my study from the perspectives of institutional history, the organisation of the field of art and the history of art collections. The prisms through which I have viewed the subject are the history of museums in Europe, the written history of art, the art association movement and the organisation of art education in relation to an ideology of enlightenment. Thus the activities of the Finnish Art Society are here mirrored for the first time in a wider context and the history of its collection located on the map of European collections. My research shows that the history of the collection of the Finnish Art Society initially depended on certain players in the visual arts and their particular leanings. The most important of these custodians were two long-serving chairmen of the society, Fredrik Cygnaeus (1807 1881) and Carl Gustaf Estlander (1834 1910). When the foundations for art activities had been laid through the establishment of the society, Cygnaeus and Estlander began to plan how the field of art might be moulded so as to improve the level of training for artists and to improve the quality of the collections and the opportunities for their display. Cygnaeus campaigned for the establishment of the Finnish Fine Arts Academy, while Estlander saw opportunities to combine the visual and applied arts. The findings of my research bring new information about the history of the collection of the Finnish Art Society, its profile, the professional abilities of those who were mainly responsible for developing it and the relationship between it and plans for reforming art education. The major findings are connected with the position of the collection in the field of art at different stages of its development. Despite the central monopoly of the Finnish Art Society in the field of art, the position of the collection was closely bound up with leading players in the field of art and their personal interests. This subservience also created an impediment to its full-blown enhancement and purposeful profiling, and it remained evident for a long time when the collection was seeking its own place in the Finnish art world.

Malesia, Singapore ja etniset kiinalaiset : Kaksi tapaa rakentaa kansallista yhtenäisyyttä

Tutkimuksen tavoitteena on perehtyä Malesian ja Singaporen kiinalaisten etniseen ja kansalliseen identiteettiin. Tutkimus tarkastelee ja vertailee erityisesti Malesian ja Singaporen valtionhallintojen keinoja rakentaa kansallista yhtenäisyyttä ja vähentää etnisen identiteetin merkitystä. Lisäksi tutkimus luo kriteerijoukon, jonka avulla voidaan vertailla Malesian ja Singaporen yhteiskuntien onnistumista tai epäonnistumista kansallisen yhtenäisyyden rakentamisessa. Tutkimustehtävä jakautuu kahteen kysymykseen: Miten Malesian ja Singaporen valtionhallinnon menetelmät vaikuttavat etnisten kiinalaisten kansalliseen ja etniseen identiteettiin, ja miten maiden menetelmät eroavat toisistaan? Lopuksi vertailemalla Malesiaa ja Singaporea tutkimuksessa päätellään luodun kriteerijoukon avulla, miten kansallinen yhtenäisyys on toteutunut näissä kahdessa maassa. Tutkimuksen teoriatausta perustuu etnistä ja kansallista identiteettiä tutkineiden Fredrik Barthin, Nathan Glazerin ja Daniel P. Moynihanin, Donald Horowitzin, Milton J. Esmanin, Benedict Andersonin, Anthony D. Smithin ja Stuart Hallin teorioihin. Nämä tutkijat painottavat eri tekijöiden merkitystä kansalliselle identiteetille ja yhtenäisyydelle, toisiaan täydentäen. Kyseessä on teoreettinen tutkimus. Siksi sen aineisto koostuu pääasiassa sekundaarilähteistä: tieteellisistä teoksista ja artikkeleista sekä sähköisistä lehtiartikkeleista. Primäärilähteitä ovat Malesian ja Singaporen perustuslait, Malesian ja Singaporen tilastokeskuksien tilastot sekä Malesian entisen pääministerin Mahathir bin Mohamadin vuonna 1991 pitämä Vision 2020 -puhe. Aineistoa on analysoitu tutkimuksen teoriataustan avulla. Monipuolisemman kuvan muodostamiseksi on tutkimukseen valittu sekä länsimaalaisten tutkijoiden että singaporelaisten ja malesialaisten tutkijoiden tutkimuksia. Lisäksi, puolueellisuuden välttämiseksi, on tutkimukseen valittu eri etnisiin ryhmiin kuuluvien tutkijoiden artikkeleita ja teoksia. Tutkimuksessa on päädytty seuraavan tulokseen. Jotta kansallinen yhtenäisyys voidaan saavuttaa Malesian ja Singaporen monietnisissä yhteiskunnissa, tulee valtionhallinnon keskittyä erityisesti seuraaviin viiteen tehtävään: kansantalouden kehittämiseen, etnisten ryhmien välisen taloudellisen tasa-arvoisuuden edistämiseen, poliittisen aktiivisuuden ja osallistumisen kannustamiseen, etnisten yhteisöjen samanarvoisuuden toteuttamiseen lain edessä ja tasa-arvoisen koulutusjärjestelmän rakentamiseen. Näiden kriteerien perusteella Malesia ja Singapore eivät ole kansallisesti yhtenäisiä valtioita. Singapore on kuitenkin kansallisesti yhtenäisempi, sillä se täyttää viidestä kriteeristä kolme, kun Malesia täyttää vain kaksi kriteeriä. Malesialla ja Singaporella on kaksi hyvin erilaista tapaa rakentaa kansallista yhtenäisyyttä, mutta lopputulokset ovat kuitenkin hyvin samankaltaiset. Tutkimus päättelee, että etnisten yhteisöjen institutionaalinen asema molemmissa maissa on yksi ratkaisevimmista esteistä kansalliselle yhtenäisyydelle.

AndroMedia - Towards a Context-aware Mobile Music Recommender

Portable music players have made it possible to listen to a personal collection of music in almost every situation, and they are often used during some activity to provide a stimulating audio environment. Studies have demonstrated the effects of music on the human body and mind, indicating that selecting music according to situation can, besides making the situation more enjoyable, also make humans perform better. For example, music can boost performance during physical exercises, alleviate stress and positively affect learning. We believe that people intuitively select different types of music for different situations. Based on this hypothesis, we propose a portable music player, AndroMedia, designed to provide personalised music recommendations using the user’s current context and listening habits together with other user’s situational listening patterns. We have developed a prototype that consists of a central server and a PDA client. The client uses Bluetooth sensors to acquire context information and logs user interaction to infer implicit user feedback. The user interface also allows the user to give explicit feedback. Large user interface elements facilitate touch-based usage in busy environments. The prototype provides the necessary framework for using the collected information together with other user’s listening history in a context- enhanced collaborative filtering algorithm to generate context-sensitive recommendations. The current implementation is limited to using traditional collaborative filtering algorithms. We outline the techniques required to create context-aware recommendations and present a survey on mobile context-aware music recommenders found in literature. As opposed to the explored systems, AndroMedia utilises other users’ listening habits when suggesting tunes, and does not require any laborious set up processes.

Long-term clinical outcome after liver transplantation

With transplant rejection rendered a minor concern and survival rates after liver transplantation (LT) steadily improving, long-term complications are attracting more attention. Current immunosuppressive therapies, together with other factors, are accompanied by considerable long-term toxicity, which clinically manifests as renal dysfunction, high risk for cardiovascular disease, and cancer. This thesis investigates the incidence, causes, and risk factors for such renal dysfunction, cardiovascular risk, and cancer after LT. Long-term effects of LT are further addressed by surveying the quality of life and employment status of LT recipients. The consecutive patients included had undergone LT at Helsinki University Hospital from 1982 onwards. Data regarding renal function – creatinine and estimated glomerular filtration rate (GFR) – were recorded before and repeatedly after LT in 396 patients. The presence of hypertension, dyslipidemia, diabetes, impaired fasting glucose, and overweight/obesity before and 5 years after LT was determined among 77 patients transplanted for acute liver failure. The entire cohort of LT patients (540 patients), including both children and adults, was linked with the Finnish Cancer Registry, and numbers of cancers observed were compared to site-specific expected numbers based on national cancer incidence rates stratified by age, gender, and calendar time. Health-related quality of life (HRQoL), measured by the 15D instrument, and employment status were surveyed among all adult patients alive in 2007 (401 patients). The response rate was 89%. Posttransplant cardiovascular risk factor prevalence and HRQoL were compared with that in the age- and gender-matched Finnish general population. The cumulative risk for chronic kidney disease increased from 10% at 5 years to 16% at 10 years following LT. GFR up to 10 years after LT could be predicted by the GFR at 1 year. In patients transplanted for chronic liver disease, a moderate correlation of pretransplant GFR with later GFR was also evident, whereas in acute liver failure patients after LT, even severe pretransplant renal dysfunction often recovered. By 5 years after LT, 71% of acute liver failure patients were receiving antihypertensive medications, 61% were exhibiting dyslipidemia, 10% were diabetic, 32% were overweight, and 13% obese. Compared with the general population, only hypertension displayed a significantly elevated prevalence among patients – 2.7-fold – whereas patients exhibited 30% less dyslipidemia and 71% less impaired fasting glucose. The cumulative incidence of cancer was 5% at 5 years and 13% at 10. Compared with the general population, patients were subject to a 2.6-fold cancer risk, with non-melanoma skin cancer (standardized incidence ratio, SIR, 38.5) and non-Hodgkin lymphoma (SIR 13.9) being the predominant malignancies. Non-Hodgkin lymphoma was associated with male gender, young age, and the immediate posttransplant period, whereas old age and antibody induction therapy raised skin-cancer risk. HRQoL deviated clinically unimportantly from the values in the general population, but significant deficits among patients were evident in some physical domains. HRQoL did not seem to decrease with longer follow-up. Although 87% of patients reported improved working capacity, data on return to working life showed marked age-dependency: Among patients aged less than 40 at LT, 70 to 80% returned to work, among those aged 40 to 50, 55%, and among those above 50, 15% to 28%. The most common cause for unemployment was early retirement before LT. Those patients employed exhibited better HRQoL than those unemployed. In conclusion, although renal impairment, hypertension, and cancer are evidently common after LT and increase with time, patients’ quality of life remains comparable with that of the general population.

TOTEM Physics

This article discusses the physics programme of the TOTEM experiment at the LHC. A new special beam optics with beta* = 90 m, enabling the measurements of the total cross-section, elastic pp scattering and diffractive phenomena already at early LHC runs, is explained. For this and the various other TOTEM running scenarios, the acceptances of the leading proton detectors and of the forward tracking stations for some physics processes are described.

TOTEM early measurements

The status of the TOTEM experiment is described as well as the prospects for the measurements in the early LHC runs. The primary goal of TOTEM is the measurement of the total p-p cross section, using a method independent of the luminosity. A final accuracy of 1% is ex- pected with dedicated β∗ = 1540 m runs, while at the beginning a 5% resolution is achievable with a β∗ = 90 m optics. Accordingly to the running scenarios TOTEM will be able to measure the elastic scattering in a wide range of t and to study the cross-sections and the topologies of diffractive events. In a later stage, physics studies will be extended to low-x and forward physics collaborating with CMS as a whole experimental apparatus.

Tests of a Roman Pot Prototype for the TOTEM Experiment

The TOTEM collaboration has developed and tested the first prototype of its Roman Pots to be operated in the LHC. TOTEM Roman Pots contain stacks of 10 silicon detectors with strips oriented in two orthogonal directions. To measure proton scattering angles of a few microradians, the detectors will approach the beam centre to a distance of 10 sigma + 0.5 mm (= 1.3 mm). Dead space near the detector edge is minimised by using two novel "edgeless" detector technologies. The silicon detectors are used both for precise track reconstruction and for triggering. The first full-sized prototypes of both detector technologies as well as their read-out electronics have been developed, built and operated. The tests took place first in a fixed-target muon beam at CERN's SPS, and then in the proton beam-line of the SPS accelerator ring. We present the test beam results demonstrating the successful functionality of the system despite slight technical shortcomings to be improved in the near future.
