The Effectiveness of Vitamin E Treatment in Alzheimer’s Disease
2019
Vitamin E was proposed as treatment for Alzheimer’s disease many years ago. However, the effectiveness of the drug is not clear. Vitamin E is an antioxidant and neuroprotector and it has anti-inflammatory and hypocholesterolemic properties, driving to its importance for brain health. Moreover, the levels of vitamin E in Alzheimer’s disease patients are lower than in non-demented controls. Thus, vitamin E could be a good candidate to have beneficial effects against Alzheimer’s. However, evidence is consistent with a limited effectiveness of vitamin E in slowing progression of dementia; the information is mixed and inconclusive. The question is why does vitamin E fail to tre…

Analisi dei determinanti di sovrappeso ed obesità in Italia
2016
Introduzione: Sovrappeso ed obesità rappresentano un problema di crescente interesse nell’ambito dei programmi sanitari nazionali dei Paesi industrializzati, sia perché la prevalenza è in costante aumento, sia perché l’eccesso ponderale è associato al rischio di sviluppare altre patologie quali diabete, malattie cardiovascolari, e alcune forme di tumore. Obiettivi: Descrivere un profilo di prevalenza del sovrappeso e dell’obesità in Italia utilizzando i dati derivanti dall’indagine Multiscopo Istat sulle “Condizioni di Salute e ricorso ai servizi sanitari” per gli anni 2005 e 2013, ed analizzare il contributo che i principali fattori di rischio hanno nel determinare una diversa distribuzion…
An Integrated Approach to Surveying Emigrants Worldwide
2019
AbstractThis chapter describes the research design applied in the research project The Emigrant Communities of Latvia: National Identity, Transnational Relations and Diaspora Politics, which forms the empirical core of this volume. It discusses this methodology in the context of other migration studies and major surveys on migration. Compared to previous studies The Emigrant Communities of Latvia is the most inclusive in terms of the target audience. All Latvians and Latvian nationals abroad were invited to participate in the survey, applying a broad and open definition of ‘Latvian diaspora’ based on personal identification with the Latvian nation and/or citizenship. Being Web-based, the su…
Dealing with preference uncertainty in contingent willingness to pay for a nature protection program: A new approach
2013
In this paper, we propose an alternative preference uncertainty measurement approach where respondents have the option to indicate their willingness to pay (WTP) for a nature protection program either as exact values or intervals from a payment card, depending on whether they are uncertain about their valuation. On the basis of their responses, we then estimate their degree of uncertainty. New within this study is that the respondent's degree of uncertainty is "revealed", while it is "stated" in those using existing measurement methods. Three statistical models are used to explore the sources of respondent uncertainty. We also present a simple way of calculating the uncertainty adjusted mea…
The relationship between environmental values and income in a transition economy: surface water quality in Latvia
2002
A contingent valuation study measured citizen willingness to pay (WTP) for an improvement in surface water quality in Latvia. The average respondent was willing to pay 0.7 per cent of household income for the environmental improvement, but that amount was much less than needed to finance the required investments in treatment facilities. While the income elasticity of WTP for the average resident was low (0.56), it increases as income increases, reaching 0.9 at an income level double the current average. As real incomes increase in Latvia, the demand for environmental quality by citizens can be expected to increase substantially.

"Od Wmci Pani już bardzo dawno miałem wiadomość, proszę, abyś mi doniosła o zdrowiu swoim i obrotach...". Wojenne doświadczenia Elżbiety z Branickiej…
2018
Elżbieta z domu Branicka była od 1732 roku trzecią żoną Jana Tarły, wojewody lubelskiego, a od 1736 roku wojewody sandomierskiego. Korespondencja pomiędzy małżonkami wskazuje na dobre relacje, oparte o wzajemna troskę i zaufania. No to ostatnie Elżbieta w pełni zasługiwała za swoja postawę w latach 1733 - 1736 przetrwać trudne czasy wojny. W rzeczywistości stawiała czoła realnym, być może wyolbrzymionym zagrożeniom. Uwypukliło to takie cechy jej charakteru, jak zdecydowanie, zaradność, i odporność na sytuacje kryzysowe. Elżbieta z Branickich Tarłowa potrafiła dbać o siebie, męża i majątek rodzinny.
