Local regularity estimates for general discrete dynamic programming equations
2022
We obtain an analytic proof for asymptotic H\"older estimate and Harnack's inequality for solutions to a discrete dynamic programming equation. The results also generalize to functions satisfying Pucci-type inequalities for discrete extremal operators. Thus the results cover a quite general class of equations.
The Syllogistic with Unity
2011
We extend the language of the classical syllogisms with the sentence-forms “At most 1 p is a q” and “More than 1 p is a q”. We show that the resulting logic does not admit a finite set of syllogism-like rules whose associated derivation relation is sound and complete, even when reductio ad absurdum is allowed.
Response of microbial biomass and carbon dynamics to changing hydrological conditions in old peat deposits
2018
Peatlands play key roles in the global ecosystem carbon (C) balance, as important C-stores. Their efficiency as long-term C-stores or atmospheric C sink is affected by the rate of microbial mineralization. Most studies on the climate change effects on the microbial communities and C-cycling in peatlands have focused on the surface layers. This thesis compared microbial biomass, community composition and internal C cycling processes in drained vs. natural peat profiles with focus on deep old peat. Using the phospholipid fatty acid (PLFA) and rRNA gene analyses, the study particularly looked at the impact of long-term drainage and the short-term effects of temperature and water content on the…
El análisis marxista de las necesidades sociales
2018
The disappearance of the so-called «real socialism» has concealed the validity of the Marxist analysis of social reality. One of the sets of hypotheses that has best maintained its heuristic capacity is the Marxist theory of needs. The Marxist hypotheses have been developed in debate with other conventional conceptions. Currently, feminism and the ecological analysis of needs are renewing the views of Heller and Habermas.
Aikuisten maahanmuuttajien kotoutumiskoulutuksen tulosten ennustaminen lähtötason arviointien perusteella
2017
Artikkelissa selvitetään aikuisten maahanmuuttajien kotoutumiskoulutuksessa saavuttamaa suomen kielen taitoa ja sitä, ennustaako koulutuksen alussa tehtävä lähtötason arviointi saavutettua kielitaitoa. Tutkimukseen osallistuneet maahanmuuttajat (N = 286) osallistuivat lähtötason arviointiin Testipisteessä. Sen jälkeen he suorittivat kotoutumiskoulutuksen opinnot peruspolun tai hitaan opintopolun mukaisesti muutamassa pääkaupunkiseudun oppilaitoksessa. Testipisteen mallin mukaisessa lähtötason arvioinnissa selvitetään maahanmuuttajan suomen kielen taitoa ja opiskeluvalmiuksia testeillä ja taustatietoja keräämällä. Niiden pohjalta maahanmuuttaja ohjataan sopivimmalle opintopolulle ja kielitai…
Solvability of a first order system in three-dimensional non-smooth domains
1985
summary:A system of first order partial differential equations is studied which is defined by the divergence and rotation operators in a bounded nonsmooth domain $\Omega\subset \bold R^3$. On the boundary $\delta\Omega$, the vanishing normal component is prescribed. A variational formulation is given and its solvability is investigated.
Mappings of finite distortion : boundary extensions in uniform domains
2015
In this paper, we consider mappings on uniform domains with exponentially integrable distortion whose Jacobian determinants are integrable. We show that such mappings can be extended to the boundary and moreover these extensions are exponentially integrable with quantitative bounds. This extends previous results of Chang and Marshall on analytic functions, Poggi-Corradini and Rajala and Akkinen and Rajala on mappings of bounded and finite distortion.

Assessing the case of Dengue in Argentina 2009: discrimination and fear
2010
After almost a decade, the re-appearance of Dengue in Argentina caused panic and fears. Unlike Bolivia, Brazil and Paraguay where policies of preventions have been followed, the future of dengue is uncertain for Argentina; this paper does not have any political affiliation but emphasizes the role that mass media play in the coverage of epidemics. The question as to whether a newspaper or mass media corporation should maintain a minimum of objectivity is too complex to be resolved in this short article. However, we have so far set forth a model which will help other researchers to interpret topics of this nature in the future. In moments of disorder, uncertainty or disaster, societies experi…
Is diabetes the cost to pay for a greater cardiovascular prevention?
2010
The recent JUPITER (Justification for the Use of statins in Primary prevention: an Intervention Trial Evaluating Rosuvastatin) trial is another study providing evidence about the effectiveness of statin therapy in reducing cardiovascular risk. Yet, in this study significantly higher glycated hemoglobin levels and incidence rates of diabetes were observed in persons treated with rosuvastatin than the placebo group. It should be noted that adverse effects on glucose metabolism have already been reported, albeit rarely, in previous trials with statins. Although the exact mechanisms involved are unknown, it seems that statins may deteriorate glycemic control by decreasing different metabolites,…
