Analyse des méthodes d'enseignement des sciences économiques dans le système éducatif Libanais
2009
Teaching economics become part of the Lebanese education system in 2000. The short history of this field is promising because of the nature of the discipline and its position in the education system in Lebanon. Teaching economics in Lebanese schools was not created on its own, but as a part of a project that aims to reform all the programs and the structures of high schools in Lebanon that started long time ago. This reform was based on relevant innovations adopted in France. Since its creation, the new section (ES) was successful in tripling its enrollment over nine years while its success rate continues to fall and decrease to become the lowest within all the other sections and taught dis…
Uncertainty measures—Problems concerning additivity
2009
Additivity of an uncertainty measure on an MV-algebra has a clear meaning. If the divisibility is dropped, we come up to a so-called Girard algebra. There we discuss strong resp. weak additivity based on so-called divisible disjoint unions resp. on additivity for all sub-MV-algebras. We obtain a description of those extensions from additive measures on an MV-algebra to the canonical Girard algebra extension of pairs which are strongly additive and valuation measures. Finally, we prove the non-existence of strongly additive measure extensions, if the underlying MV-algebra is a finite chain with more than two non-trivial elements.
Estimating the non-market benefits of water quality improvement for a case study in Spain: A contingent valuation approach
2012
Abstract This article addresses an important topic related to the application of the European Water Framework Directive (WFD) in Spanish watersheds. Results on a contingent valuation study, aimed to assess the non-market benefits of water quality improvements in the Guadiana river basin (GRB), are shown. Special attention has been paid to the issue of zero willingness-to-pay (WTP) responses, while addressing the possible presence of self-selection caused by protest responses. The results (i) indicate that sample selection bias is not a problem in our application, (ii) allow us to identify some key determinants of voting behaviour, and (iii) through the use of different econometric models al…
Competency Research in Higher Education: Conceptual and Methodological Challenges and Perspectives for Future Interdisciplinary Research
2015
In recent years, an increasing number of research projects have been dedicated to competency assessment not only in school and vocational education, but also in higher education (Blomeke, Zlatkin-T...
Monumental trees and their existence value: the case study of an Italian natural park
2015
The paper deals with the evaluation of the existence value of monumental trees in a protected area. Financial resources to be destined for protection interventions have been decreasing more and more, with a high risk of losing this natural heritage. A Contingent Valuation Method (CVM) survey was carried out among the Madonie Park (Sicily, Italy) resident households to evaluate the existence value of monumental trees of the nature trail named "Piano Sempria-Piano Pomo", represented by a population of "Giant hollies" and by 7 other individual trees. These are the main results of the CVM survey: the overall response rate was 40%, individual average WTPs ( Willingness To Pay ) were €12.37 for t…
Bile Duct Warmer in Hepatic Cryosurgery—A Pig Liver Model
1998
Freezing of the common bile duct resulted in injury, stenosis, or perforation of the bile duct in a dog model. Biliary cutaneous fistulas and bile leaks are reported as complications of hepatic cryosurgery in man. In an ex vivo pig liver model we compared freezing close to the bile duct with and without warming the bile duct with warmed saline solution via an inserted catheter ("bile duct warmer"). The recorded temperatures at the outer wall of the bile duct were -50 degrees C after 10 min of freezing without and 5. 8 degrees C with the use of the warmer (P0.001, two-way ANOVA). The bile duct warmer system may be a simple and inexpensive device in reducing perioperative morbidity after hepa…
Efficacy of protection by latex gloves during orthodontic therapy.
2000
The wearing of gloves during orthodontic or dental treatment is generally indicated for reasons of hygiene and protection against infection. This study was aimed at determining the extent and localization of perforations caused by the various orthodontic treatment techniques and interrupting the infection barrier. The impermeability was tested by means of a water retention test according to European standard EN 455, Part 1, performed on 1600 Centramed (Centramed, Koblenz), Tekmedic and SafeEx non-sterile disposable latex gloves (both by Safe Med, Switzerland) and Safe Gan latex gloves with an additional acrylate coating (also by Safe Med). The perforation rate in unused gloves was between 0…
The use of positively valued adjectives and adverbs in Polish and Estonian casual conversations
2019
Abstract In this paper cultural differences between Polish and Estonian conversational strategies are analysed in respect of how the evaluative words are used and what their degree of deliberateness is. The study compares the usage of adjectives and adverbs with positive value in the excerpts from Polish and Estonian corpora of casual conversation. The quantitative and qualitative comparison demonstrates that their overall frequency and the pragmatic functions are very similar. The differences of the conversational styles lay in greater accumulation and intensification of the evaluatives in the Polish conversations and in the tendency to externalize the positive affect in the Estonian ones.…
Discovery of benzimidazole-based Leishmania mexicana cysteine protease CPB2.8ΔCTE inhibitors as potential therapeutics for leishmaniasis
2018
Abstract: Chemotherapy is currently the only effective approach to treat all forms of leishmaniasis. However, its effectiveness is severely limited due to high toxicity, long treatment length, drug resistance, or inadequate mode of administration. As a consequence, there is a need to identify new molecular scaffolds and targets as potential therapeutics for the treatment of this disease. We report a small series of 1,2‐substituted‐1H‐benzo[d]imidazole derivatives (9ad) showing affinity in the submicromolar range (Ki = 0.150.69 μM) toward Leishmania mexicanaCPB2.8ΔCTE, one of the more promising targets for antileishmanial drug design. The compounds confirmed activity in vitro against intrace…
Application of DNA techniques for identification using human dental pulp as a source of DNA
1992
Dental pulp tissue could be obtained in most cases from materials obtained under experimental conditions and from forensic casework (air accidents, burned and putrefied bodies). Teeth extracted during dental treatment (n = 30) were stored for 6 weeks and 4 years at room temperature. In addition teeth (n = 10) extracted from jaw fragments that had been stored for 15 years at room temperature, and teeth extracted post mortem from actual identification cases (n = 8) were investigated. Following extraction from dental pulp tissue the DNA concentration was measured by fluorometry. The amount of DNA obtained from the dental pulp tissue of a single tooth varied from 6 micrograms to 50 micrograms D…
