The Social Nature of Chronic Noncommunicable Diseases and How to Tackle Them Through Communication Technology, Training, and Outreach

2011

As world leaders prepare for the United Nations High Level Meeting on Noncommunicable Diseases, to take place in September 2011, international organizations, nongovernmental organizations, and economic and business fora have created new alliances and initiatives to accelerate research, advocacy, and political commitment. This article argues that the time is propitious to reflect on the social nature of the most common behavioral noncommunicable disease determinants, including tobacco and alcohol use, physical inactivity, and unhealthy diet. Evidence is presented related to the fact that these diseases are profoundly rooted in social and community ties and points to the need for a modern com…

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…

Climate Change and Global Justice: New Problem, Old Paradigm?

2014

In this paper, we focus on the conceptualization of climate change as an issue of global justice. While we do not deny that climate change raises fundamental and dramatic issues of justice among peoples as well as generations, our claim is that the language of global justice can obscure the fact that problems provoked by climate change lack some characteristic features of problems of global justice, while possessing others that are not characteristic of such problems. We begin by describing briefly how we got to where we are, climatically speaking; we go on to show why it is plausible to think of climate change as provoking problems of global justice; point out four respects in which this d…

Creencias de los estudiantes de educación secundaria sobre la naturaleza de la ciencia y los modelos científicos: un estudio transversal

2018

Las trayectorias de empleabilidad de los jóvenes que salen del sistema de protección se ven condicionadas por su situación de exclusión social. Nuestra investigación persigue: a) analizar las trayectorias de los jóvenes extutelados y b) examinar cómo sus experiencias vitales y laborales influyen en su situación de exclusión. Se realizó un estudio de casos múltiples con cuatro jóvenes inmigrantes y tres nacionales. La selección de los casos tuvo en cuenta: a) haber estado acogido al sistema de protección, b) haber pasado un mínimo de 6 meses en un programa de inserción laboral, c) haber transcurrido 6 años después de finalizar el proyecto de inserción. En el estudio se utilizaron entrevistas…

Choix du système électoral et Convention européenne des droits de l'homme : quelques observations à la lumière d'une affaire concernant une loi élect…

2013

Within the space of less than two years the European Court of Human Rights and the Italian Constitutional Court have returned almost opposing judgments on the question of the observance of political rights by Italy’s 2005 electoral law. The ECHR found the applications made to it by groups of electors inadmissible given the manifestly ill-founded character of the grievances they were based on. The Constitutional Court, on the contrary, concluded that the law was unconstitutional. At first sight, the differing approaches by the two courts and the differing conclusions they reached may be viewed as an expression of the complementary nature of the European system of protection of human rights w…

Fault Diagnostics for Electrically Operated Pitch Systems in Offshore Wind Turbines

2016

This paper investigates the electrically operated pitch systems of offshore wind turbines for online condition monitoring and health assessment. The current signature based fault diagnostics is developed for electrically operated pitch systems using model-based approach. The electrical motor faults are firstly modelled based on modified winding function theory and then, current signature analysis is performed to detect the faults. Further, in order to verify the fault diagnostics capabilities in realistic conditions, the operating profiles are obtained from FAST simulation of offshore wind turbines in various wind conditions. In this way, the applicability of current signature analysis for …

Two-Step Solution-Processed Two-Component Bilayer Phthalocyaninato Copper-Based Heterojunctions with Interesting Ambipolar Organic Transiting and Eth…

2016

International audience; The two-component phthalocyaninato copper-based heterojunctions fabricated from n-type CuPc(COOC8H17)(8) and p-type CuPc(OC8H17)(8) by a facile two-step solution-processing quasi-Langmuir-Shafer method with both n/p- and p/n-bilayer structures are revealed to exhibit typical ambipolar air-stable organic thin-film transistor (OTFT) performance. The p/n-bilayer devices constructed by depositing CuPc(COOC8H17)(8) film on CuPc(OC8H17)(8) sub-layer show superior OTFT performance with hole and electron mobility of 0.11 and 0.02 cm(2) V-1 s(-1), respectively, over the ones with n/p-bilayer heterojunction structure with the hole and electron mobility of 0.03 and 0.016 cm(2) …

Guided Tour Influence on Cruise Tourist Experience in a Port of Call: An eWOM and Questionnaire-Based Approach

2016

The study aims at exploring the importance of guided tours in cruise tourists experience while visiting a port of call and analyzing qualitative (electronic word of mouth from Tripadvisor) and quantitative (personal interviews with tourists) data. The results obtained from the electronic word of mouth analysis suggest that taking a guided tour is a highly satisfactory and sentimentally positive experience for the cruise tourist. Moreover, the empirical findings revealed that taking a guided tour has a moderating effect on (1) the interaction between destination image–satisfaction, (2) the satisfaction–loyalty causal relationship and (3) the destination image formation process regarding the …

Defining the genomic signature of totipotency and pluripotency during early human development.

2013

The genetic mechanisms governing human pre-implantation embryo development and the in vitro counterparts, human embryonic stem cells (hESCs), still remain incomplete. Previous global genome studies demonstrated that totipotent blastomeres from day-3 human embryos and pluripotent inner cell masses (ICMs) from blastocysts, display unique and differing transcriptomes. Nevertheless, comparative gene expression analysis has revealed that no significant differences exist between hESCs derived from blastomeres versus those obtained from ICMs, suggesting that pluripotent hESCs involve a new developmental progression. To understand early human stages evolution, we developed an undifferentiation netw…
