Predictors of mortality in old age : contribution of self-rated health, physical functions, life satisfaction and social support on survival among ol…

2006

Length of life is perhaps the best single indicator of the health of a population. The purpose of the present series of studies was to explore the potential predictors of mortality in older people with special emphasis on self-rated health, physical functions, life satisfaction and perceived social support.The four studies used prospective data drawn from 1) the Evergreen study, where mortality was followed for 10 years in an entire cohort of the 75- and 80-year-old (N=650) residents of the city of Jyväskylä, Finland, 2) the Functional capacity of men born in 1906-10, 1926-30 and 1946-50 research project from which two oldest age cohorts, 257 residents of the city of Jyväskylä, Finland aged…

Looking for determinants of willingness-to-pay for Sibelius Hall, Lahti

2017

The aim of this paper is to determine the factors affecting the willingness-to-pay for a local concert hall, namely Sibelius Hall in Lahti. Our study argues that a high income, the use of cultural services and a positive attitude towards culture were connected to a high willingness-to-pay for Sibelius Hall. Our study revealed that “I do not know” answers can be partly explained by the character of cultural preferences being an acquired taste. As a consequence, the users and respondents exhibiting a positive attitude towards culture may choose the “I do not know” option instead of making a zero bid. peerReviewed

Larval life history, transmission strategies, and the evolution of intermediate host exploitation by complex life-cycle parasites

2007

Complex life-cycle parasites use their intermediate hosts both as an energy source and as a vessel for transmission to the next host in the life cycle. Parasites that grow rapidly to a large size may have high fitness (e.g. time spent in uninfective stages is limited), yet those that grow too aggressively may reduce host viability and their own probability of successful transmission. I examined aspects of both the growth and transmission strategy of an acanthocephalan (Acanthocephalus lucii) in its isopod intermediate host. In an experimental infection, the relative rate of larval parasite growth slowed over time, and eventually parasites seemed to reach a threshold biomass sustainable by t…

Öjanjärven virkistyskäyttö ja sen taloudellinen arvottaminen

1998

Öjanjärvi on syntynyt vuonna 1969, jolloin se padottiin merenlahdesta erilliseksi makeanvedenaltaaksi suurteollisuuden tarpeisiin. Toukokuussa 1998 toteutuneen uuden säännöstelyn mukaisesti järven veden pinnantaso irrotettiin meriveden korkeudesta ja vakautettiin pysyvästi korkeammalle tasolle. Tutkimusraportti pyrkii vastaamaan seuraaviin kysymyksiin: Kuinka arvokas Öjanjärvi on käyttäjilleen niin taloudellisesti kuin henkisesti? Miten ja missä laajuudessa järveä käytetään? Virkistyskäytön taloudellisen arvon määrittelemiseksi on käytetty soveltuvin osin contingent valuation -menetelmää. CV-menetelmässä virkistyskäytön rahamääräinen arvioiminen tapahtuu yksilöiden ilmaisemien maksuhalukkuu…

Data from: Protection first then facilitation: a manipulative parasite modulates the vulnerability to predation of its intermediate host according to…

2011

Many trophically-transmitted parasites with complex life cycles manipulate their intermediate host behavior in ways facilitating their transmission to final host by predation. This facilitation generally results from lowering host’s anti-predatory defences when the parasite is infective to the final host. However, a recent theoretical model predicts that an optimal parasitic strategy would be to protect the intermediate host from predation when non-infective, before switching to facilitation when the infective stage is reached. We tested this hypothesis in the fish acanthocephalan parasite Pomphorhynchus laevis using the amphipod Gammarus pulex as intermediate host. Gammarids parasitized by…

Germinal matrix hemorrhage-intraventricular hemorrhage: pathogenesis and outcomes

2015

Germinal matrix hemorrhage-intraventricular hemorrhage (GMH-IVH) is one of the CNS injuries affecting preterm infants occurring in about 15%-20% of subjects weighing less than 1500 g. Currently, using ultrasonography, we recognize three grades of GMH-IVH. Grade I involving the subependymal parenchyma and/or extending in less than 10% of the ventricle, grade II with intraventricular bleeding not expanding in more than 50% of the ventricle, grade III characterized by consistent (> 50%)intraventricu- lar bleeding with ventricular dilatation. A concomitant intraparenchymal lesion (IPL), due to a venous infarction (ex grade IV), can be associated with any grade of IVH, worsening the prognosis. P…
