Trademarks,Geographical Indications and Environmental Labelling to Promote Biodiversity: The Case of Agroforestry Coffee in India

The district of Kodagu, also called Coorg, in the Western Ghats of India produces 2% of the world's coffee, the expansion and intensification of which have reduced the forest cover by more than 30% in 20 years. Innovative actions are therefore urgently required to link economic development and biodiversity conservation, and stakeholders are exploring three strategies to add value to coffee from Coorg and prevent further biodiversity erosion: registration of trademarks; geographical indications; and environmental certification, via eco‐labels. This article analyses their respective strengths and weaknesses and discusses the synergies between them.     

Un-Silencing the Past: The Writings of Toussaint Louverture

Contrary to most slave revolts, the Haitian Revolution (1791–1804) has left a rich archival record that includes documents written by the dominant classes as well as by the people of African descent. Of these, the most notable author was Toussaint Louverture, who during the 1790s wrote hundreds of letters, pamphlets, and proclamations (a few of them in his own hand) in an effort to shape official and public opinion in France and Saint-Domingue (Haiti). Particularly worthy of note is a 21-page memoir that Louverture wrote shortly before his death and that defended his public record as governor of Saint-Domingue.     

Political Correctness and the Study of Racial Differences

I tabulate international data showing Africans and Asians scoring at opposite ends of a continuum with Europeans falling in the middle. This Asian-European-African gradient occurs in mean scores on a long list of characteristics including brain size, crime, sex hormones, sexual behavior, personality, family stability, speed of physical maturation, twinning rate, and social organization. It seems to me that only evolutionary theories are able to fully explain the consistency of the pattern across so many variables. Theories about social inequalities and social problems may need to be revised in the light of this new in/onnation. This challenge to the social science orthodoxy brought political correctness out in force against me, some examples of which I document here. However, numerous benefits derive from studying race particularly in the field of medicine which I illustrate with special emphasis on AIDS. I conclude that if more scientists would speak openly about the views they now voice only in private, our world would become not only a safer place, but a more enlightened one as well.     

Using heuristics to find minimal unsatisfiable subformulas in satisfiability problems

In this paper, we propose efficient algorithms to extract minimal unsatisfiable subsets of clauses or variables in unsatisfiable propositional formulas. Such subsets yield unsatisfiable propositional subformulas that become satisfiable when any of their clauses or variables is removed. These subformulas have numerous applications, including proving unsatisfiability and post-infeasibility analysis. The algorithms we propose are based on heuristics, and thus, can be applied to large instances. Furthermore, we show that, in some cases, the minimality of the subformulas can be proven with these algorithms. We also present an original algorithm to find minimum cardinality unsatisfiable subformulas in smaller instances. Finally, we report computational experiments on unsatisfiable instances from various sources, that demonstrate the effectiveness of our algorithms.     

The Coalitional Nash Bargaining Solution

The coalitional Nash bargaining solution is defined to be the core allocation for which the product of players' payoffs is maximal. We consider a non‐cooperative model with discounting in which one team may form and every player is randomly selected to make a proposal in every period. The grand team, consisting of all players, generates the largest surplus. But a smaller team may form. We show that as players get more patient if an efficient and stationary equilibrium exists, it must deliver payoffs that correspond to the coalitional Nash bargaining solution. We also characterize when an efficient and stationary equilibrium exists, which requires conditions that go beyond the nonemptiness of the core.     

Categorical multiblock linear discriminant analysis

Techniques of credit scoring have been developed these last years in order to reduce the risk taken by banks and financial institutions in the loans that they are granting. Credit Scoring is a classification problem of individuals in one of the two following groups: defaulting borrowers or non-defaulting borrowers. The aim of this paper is to propose a new method of discrimination when the dependent variable is categorical and when a large number of categorical explanatory variables are retained. This method, Categorical Multiblock Linear Discriminant Analysis, computes components which take into account both relationships between explanatory categorical variables and canonical correlation between each explanatory categorical variable and the dependent variable. A comparison with three other techniques and an application on credit scoring data are provided.     

Adolescents' beliefs about marijuana use: a comparison of regular users, past users and never/occasional users

A questionnaire investigating adolescents' opinions and experiences regarding marijuana use was administered to 163 adolescents and young adults (96 boys and 67 girls) aged 13 to 20 (mean age = 16.8, s.d. = 1.5). Items referred to marijuana and other substances' dangerousness, representations regarding the positive and negative consequences of marijuana use. Responses were compared according to marijuana use status (classified into never/occasional use, current regular use and past regular use). Results show that adolescents' opinions differ according to their experience with marijuana use. Current regular users evaluate marijuana as less dangerous, but alcohol and heroin as more dangerous in comparison with never/occasional and past users. Current and past users are more likely to define marijuana as a medical drug and a plant used in agriculture, and less likely to define it as an illegal drug. Current and past users evaluate marijuana use as a way to cope with stress, to relax to a greater extent than do never/occasional users do. The latter attribute more negative consequences to marijuana use such as diminished driving ability and school performance and a pathway to hard drugs.     

Selecting a foreign partner for technology transfer

This article proposes a method for evaluating the strategy and resources of local and foreign partners in technology transfer based on normal sound management practice. The author has had considerable experience of the process in business ventures in the ASEAN region and has found that not enough time, effort and research is invested in the initial negotiations. He suggests that a year or more should be allowed for the foreign staff to become familiar with the country and the business practices of local companies.
