Interaction Between Food Attributes in Markets: The Case of Environmental Labeling

Some consumers derive utility from using products produced with specific processes, such as environmentally friendly practices. Means of verifying these credence attributes, such as certification, are necessary for the market to function effectively. A substitute or complementary solution may exist when consumers perceive a relationship between a process attribute and other verifiable product attributes. We present a model where the level of search and experience attributes influences the likelihood of production of eco-friendly products. Our results suggest that the market success of eco-friendly food products requires a mix of environmental and other verifiable attributes that together signal credibility.environmental labeling, food attributes, food marketing, quality perception, Food Consumption/Nutrition/Food Safety,

Neuroactive substance and uses of one such substance

Co-inventeur en collaboration avec le laboratoire UPRES EA MMS (Substances Marines à Activités Biologiques) – Professeur JF Biard de l’Université de Nantes nous avons déposé un brevet. Ce brevet concerne l’utilisation d’une molécule isolée d’un corail comme traceur des canaux calciques dépendants du potentiel à bas seuil d’activation. A ce jour, il s’agit de la première molécule connue pour agir de cette façon. Un brevet français a été déposé tant pour la structure de cette molécule que pour son activité particulière

II.4 The “ready to use” CoRoT data

This book is dedicated to all the people interested in the CoRoT mission and the beautiful data that were delivered during its six year duration. Either amateurs, professional, young or senior researchers, they will find treasures not only at the time of this publication but also in the future twenty or thirty years. It presents the data in their final version, explains how they have been obtained, how to handle them, describes the tools necessary to understand them, and where to find them. It also highlights the most striking first results obtained up to now. CoRoT has opened several unexpected directions of research and certainly new ones still to be discovered

Small D-pi-A Systems with o-Phenylene-Bridged Accepting Units as Active Materials for Organic Photovoltaics

Donor-acceptor (D--A) systems that combine triarylamine donor blocks and dicyanovinyl (DCV) acceptor groups have been synthesized. Starting from the triphenylamine (TPA)thiopheneDCV compound (1) as a reference system, various synthetic approaches have been developed for controlling the light-harvesting properties and energy levels of the frontier orbitals in this molecule. Thus, the introduction of methoxy groups onto TPA, the replacement of one phenyl ring of TPA by a thiophene ring, or the extension of the -conjugating spacer group lead to the modulation of the HOMO level. On the other hand, the fusion of the DCV group onto the vicinal thiophene ring by an ortho-phenylene bridge allows for a specific fine-tuning of the LUMO level. The electronic properties of the molecules were analyzed by using UV/Vis spectroscopy and cyclic voltammetry and the compounds were evaluated as donor materials in basic bilayer planar heterojunction solar cells by using C-60 as acceptor material. The relationships between the electronic properties of the donors and the performance of the corresponding photovoltaic devices are discussed. Bilayer planar heterojunction solar cells that used reference compound 1 and C-70 afforded power-conversion efficiencies of up to 3.7%

Історія радянської України в бібліографічних покажчиках англомовних праць другої половини ХХ століття

У статті проаналізовано бібліографічні покажчики англомовної слов’янознавчої та радянознавчої літератури, видрукувані в англомовних країнах протягом другої половини ХХ ст. Зроблено спробу визначити місце, яке у них займали праці з історії України, зокрема ті, що стосуватися пізньосталінського та хрущовського періодів.В статье анализируются библиографические указатели англоязычной славяноведческой и советологической литературы, опубликованные в англоязычных странах во второй половине ХХ века. Сделана попытка охарактеризовать положение, которое в них занимала история Советской Украины, особенно ее позднесталинский и хрущевский периоды.In the article, the bibliographic guides to the English-language publications in Slavic, East European and Soviet Studies that were published in the second half of the 20th century are analyzed. The special attention is given to history of Ukraine from the second half of the 1940s till the mid-1960s as a particular subject in those guides

Mice with cisplatin and oxaliplatin-induced painful neuropathy develop distinct early responses to thermal stimuli

<p>Abstract</p> <p>Background</p> <p>Cisplatin has been in use for 40 years for treatment of germ line and other forms of cancer. Oxaliplatin is approved for treatment of metastatic colorectal cancer. Thirty to forty percent of cancer patients receiving these agents develop pain and sensory loss. Oxaliplatin induces distinctive cold-associated dysesthesias in up to 80% of patients.</p> <p>Results</p> <p>We have established mouse models of cisplatin and oxaliplatin-induced neuropathy using doses similar to those used in patients. Adult male C57BL6J mice were treated with daily intraperitoneal injection for 5 days, followed by 5 days of rest, for two cycles. Total cumulative doses of 23 mg/kg cisplatin and 30 mg/kg oxaliplatin were used. Behavioral evaluations included cold plate, von Frey, radiant heat, tail immersion, grip strength and exploratory behavior at baseline and at weekly intervals for 8 weeks. Following two treatment cycles, mice in the cisplatin and oxaliplatin treatment groups demonstrated significant mechanical allodynia compared to control mice. In addition, the cisplatin group exhibited significant thermal hyperalgesia in hind paws and tail, and the oxaliplatin group developed significant cold hyperalgesia in hind paws.</p> <p>Conclusion</p> <p>We have therefore established a model of platinum drug-induced painful peripheral neuropathy that reflects the differences in early thermal pain responses that are observed in patients treated with either cisplatin or oxaliplatin. This model should be useful in studying the molecular basis for these different pain responses and in designing protective therapeutic strategies.</p

Toward sustainable organic semiconductors from a broad palette of green reactions

New conjugated materials, based on the triphenylamine-thiophene moiety and integrating azomethine bonds with a dibenzofuran unit or a cyanovinyl bond with a phenylthiophene or bithiophene unit, have been synthesized by using a wide range of green reactions such as direct heteroarylation coupling reactions, Knoevenagel and Schiff-base condensations and Stille cross-coupling reactions using ionic-liquid-supported thiophenylstannane. The electronic properties of the new molecules were analyzed by UV/Vis spectroscopy and cyclic voltammetry. The potential use of the molecules as donor materials for photovoltaic conversion were evaluated in simple bilayer solar cells using C60 as the acceptor material

Bonus versus penalty: how robust are the effects of contract framing?

We study the relative effectiveness of contracts that are framed either in terms of bonuses or penalties. In one set of treatments subjects know at the time of effort provision whether they have achieved the bonus / avoided the penalty. In another set of treatments subjects only learn the success of their performance at the end of the task. We fail to observe a contract framing effect in either condition: effort provision is statistically indistinguishable under bonus and penalty contracts

Emotional intelligence buffers the effect of physiological arousal on dishonesty

We studied the emotional processes that allow people to balance two competing desires: benefitting from dishonesty and keeping a positive self-image. We recorded physiological arousal (skin conductance and heart rate) during a computer card game in which participants could cheat and fail to report a certain card when presented on the screen to avoid losing their money. We found that higher skin conductance corresponded to lower cheating rates. Importantly, emotional intelligence regulated this effect; participants with high emotional intelligence were less affected by their physiological reactions than those with low emotional intelligence. As a result, they were more likely to profit from dishonesty. However, no interaction emerged between heart rate and emotional intelligence. We suggest that the ability to manage and control emotions can allow people to overcome the tension between doing right or wrong and license them to bend the rules
