Depuis la révolution industrielle, l’évolution de la technologie bouleverse le monde de la fabrication. Aujourd'hui, de nouvelles technologies telles que le prototypage rapide font une percée dans des domaines comme celui de la fabrication de bijoux, appartenant jadis à l'artisanat et en bouscule les traditions par l'introduction de méthodes plus rapides et plus faciles. Cette recherche vise à répondre aux deux questions suivantes : - ‘En quoi le prototypage rapide influence-t-il la pratique de fabrication de bijoux?’ - ‘En quoi influence-t-il de potentiels acheteurs dans leur appréciation du bijou?’ L' approche consiste en une collecte de données faite au cours de trois entretiens avec différents bijoutiers et une rencontre de deux groupes de discussion composés de consommateurs potentiels. Les résultats ont révélé l’utilité du prototypage rapide pour surmonter un certain nombre d'obstacles inhérents au fait-main, tel que dans sa géométrie, sa commercialisation, et sa finesse de détails. Cependant, il se crée une distance entre la main du bijoutier et l'objet, changeant ainsi la nature de la pratique. Cette technologie est perçue comme un moyen moins authentique car la machine rappelle la production de masse et la possibilité de reproduction en série détruit la notion d’unicité du bijou, en réduisant ainsi sa charge émotionnelle. Cette recherche propose une meilleure compréhension de l'utilisation du prototypage rapide et de ses conséquences dans la fabrication de bijoux. Peut-être ouvrira-t-elle la voie à une recherche visant un meilleur mariage entre cette technique et les méthodes traditionnelles.

La production de biodiésel par des microalgues est intéressante à plusieurs niveaux. Dans le premier chapitre, un éventail de pour et contres concernant l’utilisation de microalgues pour la production de biocarburant sont ici révisés. La culture d’algues peut s'effectuer en utilisant des terres non-arables, de l’eau non-potable et des nutriments de base. De plus, la biomasse produite par les algues est considérablement plus importante que celle de plantes vasculaires. Plusieurs espèces on le contenu lipidique en forme de triacylglycérols (TAGs), qui peut correspondre jusqu'à 30% - 40% du poids sec de la biomasse. Ces proportions sont considérablement plus élevées que celui des huiles contenues dans les graines actuellement utilisées pour le biodiésel de première génération. Par contre, une production pratique et peu couteuse de biocarburant par des microalgues requiert de surpasser plusieurs obstacles. Ceci inclut le développement de systèmes de culture efficace à faible coût, de techniques de récupération requérant peu d’énergie, et de méthodes d’extraction et de conversion de l’huile non-dommageables pour l’environnement et peu couteuses. Le deuxième chapitre explore l'une des questions importantes soulevées dans le premier chapitre: la sélection d'une souche pour la culture. Une collection de souches de microalgues d'eau douce indigène au Québec a été établi et examiné au niveau de la diversité physiologique. Cette collection est composée de cent souches, que apparaissaient très hétérogènes en terme de croissance lorsque mises en culture à 10±2 °C ou 22±2 °C sur un effluent secondaire d’une usine municipale de traitement des eaux usées (EU), défini comme milieu Bold's Basal Medium (BBM). Des diagrammes de dispersion ont été utilisés pour étudier la diversité physiologique au sein de la collection, montrant plusieurs résultats intéressants. Il y avait une dispersion appréciable dans les taux de croissance selon les différents types de milieux et indépendamment de la température. De manière intéressante, en considérant que tous les isolats avaient initialement été enrichis sur milieu BBM, la distribution était plutôt symétrique autour de la ligne d’iso-croissance, suggérant que l’enrichissement sur BBM n’a pas semblé biaiser la croissance des souches sur ce milieu par rapport aux EU. Également, considérant que les isolats avaient d’abord été enrichis à 22°C, il est assez surprenant que la distribution de taux de croissance spécifiques soit aussi symétrique autour de la ligne d’iso-croissance, avec grossièrement des nombres égaux d’isolats de part et d’autre. Ainsi, l’enrichissement à 22°C ne semble pas biaiser les cellules vers une croissance à cette température plutôt que vers 10°C. Les diagrammes de dispersion obtenus lorsque le pourcentage en lipides de cultures sur BBM ont été comparées à des cultures ayant poussé sur EU soit à 10°C ou 22°C rendent évident que la production de lipides est favorisée par la culture sur EU aux deux températures, et que la production lipidique ne semble pas particulièrement plus favorisée par l’une ou l’autre de ces températures. Lorsque la collection a été examinée pour y déceler des différences avec le site d’échantillonnage, une analyse statistique a montré grossièrement que le même degré de diversité physiologique était retrouvé dans les échantillons des deux différents sites. Le troisième chapitre a poursuivi l'évaluation de la culture d'algues au Québec. L’utilisation de déchets industriels riches en nutriments minéraux et en sources de carbone pour augmenter la biomasse finale en microalgues et le produit lipidique à faible coût est une stratégie importante pour rendre viable la technologie des biocarburants par les algues. Par l’utilisation de souches de la collection de microalgues de l’Université de Montréal, ce rapport montre pour la première fois que des souches de microalgues peuvent pousser en présence de xylose, la source de carbone majoritairement retrouvée dans les eaux usées provenant des usines de pâte et papier, avec une hausse du taux de croissance de 2,8 fois par rapport à la croissance photoautotrophe, atteignant jusqu’à µ=1,1/jour. En présence de glycérol, les taux de croissance atteignaient des valeurs aussi élevées que µ=1,52/jour. La production lipidique augmentait jusqu’à 370% en présence de glycérol et 180% avec le xylose pour la souche LB1H10, démontrant que cette souche est appropriée pour le développement ultérieur de biocarburants en culture mixotrophe. L'ajout de xylose en cultures d'algues a montré certains effets inattendus. Le quatrième chapitre de ce travail a porté à comprendre ces effets sur la croissance des microalgues et la production de lipides. Quatre souches sauvages indigènes ont été obersvées quotidiennement, avant et après l’ajout de xylose, par cytométrie en flux. Avec quelques souches de Chlorella, l’ajout de xylose induisait une hausse rapide de l’accumulation de lipide (jusqu’à 3,3 fois) pendant les premières six à douze heures. Aux temps subséquents, les cellules montraient une diminution du contenu en chlorophylle, de leur taille et de leur nombre. Par contre, l’unique membre de la famille des Scenedesmaceae avait la capacité de profiter de la présence de cette source de carbone sous culture mixotrophe ou hétérotrophe sans effet négatif apparent. Ces résultats suggèrent que le xylose puisse être utilisé avant la récolte afin de stimuler l’augmentation du contenu lipidique de la culture d’algues, soit en système de culture continu ou à deux étapes, permettant la biorestauration des eaux usées provenant de l’industrie des pâtes et papiers. Le cinquième chapitre aborde une autre déché industriel important: le dioxyde de carbone et les gaz à effet de serre. Plus de la moitié du dioxyde de carbone qui est émis dans l'atmosphère chaque jour est dégagé par un processus stationnaire, soit pour la production d’électricité ou pour la fabrication industrielle. La libération de CO2 par ces sources pourrait être atténuée grâce à la biorestauration avec microalgues, une matière première putative pour les biocarburants. Néanmoins, toutes les cheminées dégagent un gaz différent, et la sélection des souches d'algues est vitale. Ainsi, ce travail propose l'utilisation d’un état de site particulier pour la bioprospection de souches d'algues pour être utilisé dans le processus de biorestauration. Les résultats montrent que l'utilisation d'un processus d'enrichissement simple lors de l'étape d'isolement peut sélectionner des souches qui étaient en moyenne 43,2% mieux performantes dans la production de biomasse que les souches isolées par des méthodes traditionnelles. Les souches isolées dans ce travail étaient capables d'assimiler le dioxyde de carbone à un taux supérieur à la moyenne, comparées à des résultats récents de la littérature.

Alice au pays des merveilles et Nietzsche n'ont en commun ni la dentelle ni la chanson. Quelque chose de beaucoup plus fort les unit toutefois; nous le découvrirons peut-être ce jour où voleront les cochons. Ou à la fin de cette pièce, selon le bon vouloir des principaux-ales intéressé-e-s. Pendant ce temps, du fin fond de leur enclos, ils et elles n'en peuvent plus d'attendre. Leur salut ? L'heure du glas ? Leur heure de gloire ? Grands incapables, pugilistes décadents qui se tuent à ne pas se tuer, se déchaînent dans le verbiage, s'érigeant malgré eux contre toute forme de verve. Combattre cet Autre qui s'immisce insidieusement en soi et qui conduit à la perte du moi. C'est dans une folle lucidité que les égos se dérangent sans échanger, s'attaquent sans s'atteindre, hurlent sans être entendus, dans l'espoir, peut-être, de se réveiller in the land of Nod. Comme l’indique le titre, Chroniques de maux (de l’extrême ordinaire) met en scène une suite de chroniques dans lesquelles les principaux-ales intéressé-e-s témoignent de leur mal-être, et ce, à travers l’exploration de lieux communs. La dramaturgie tente, entre autres, de mettre en place une poésie de l’invective et de l’humour; une esthétique du trash-talking et de la logorrhée. Une importance particulière est accordée au rythme et au langage. L’atmosphère alterne résolument lourdeur et ludisme. La pièce Rouge Gueule, d'Étienne Lepage, présente une mécanique visant manifestement à « attaquer » l'Autre, qu’il s’agisse d’un personnage ou du lecteur-spectateur. Les attaques se perpètrent d'une part par un humour cru, influencé par la culture populaire, le trivial; un humour qui fonctionne de manière plutôt classique en convoquant des procédés aisément repérables et sans cesse réutilisés par l'auteur. D’autre part, la mécanique de « combat » se manifeste par l'invective, ainsi que par une violence caractérisée, du début à la fin, par un manque dans la motivation des actions. Ainsi, l’étude Attaques à vide. Bousculer la situation théâtrale au confluent de l’humour et la violence s’intéresse à Rouge Gueule, aux relations qu'entretiennent l’humour et l'univers brutal de la pièce, dans la perspective où l’humour est inextricablement lié à la violence. Une attention particulière est portée sur le personnage type de Lepage de même que sur l’esthétique de « l'arsenal » trash. Cette dernière est analysée afin de mieux circonscrire les attaques : sont-elles des moyens, et le cas échéant, pour parvenir à quelle fin puisque la fable, et donc la « quête », dans le théâtre contemporain est souvent remise en question. Cette étude verra comment les attaques « à vide », sont, chez Lepage, la force motrice de ce que Hans-Thies Lehmann nomme la « situation théâtrale ».

The present work is an attempt to understand the characteristics of the upper troposphere and lower stratosphere over the Asian summer monsoon region, more specifically over the Indian subcontinent. Mainly three important parameters are taken such as zonal wind, temperature and ozone over the UT/LS of the Asian summer monsoon region. It made a detailed study of its interannual variability and characteristics of theses parameters during the Indian summer monsoon period. Monthly values of zonal wind and temperature from the NCEP/NCAR reanalysis for the period 1960-2002 are used for the present study. Also the daily overpass total ozone data for the 12 Indian stations (from low latitude to high latitudes) from the TOMS Nimbus 7 satellite for the period 1979 to 1992 were also used to understand the total ozone variation over the Indian region. The study reveals that if QBO phases in the stratosphere is easterly or weak westerly then the respective monsoon is found to be DRY or below Normal . On the other hand, if the phase is westerly or weak easterly the respective Indian summer monsoon is noted as a WET year. This connection of stratospheric QBO phases and Indian summer monsoon gives more insight in to the long-term predictions of Indian summer monsoon rainfall. Wavelet analysis and EOF methods are the two advanced statistical techniques used in the present study to explore more information of the zonal wind that from the smaller scale to higher scale variability over the Asian summer monsoon region. The interannual variability of temperature for different stratospheric and tropospheric levels over the Asian summer monsoon region have been studied. An attempt has been made to understand the total ozone characteristics and its interannual variablilty over 12 Indian stations spread from south latitudes to north latitudes. Finally it found that the upper troposphere and lower stratosphere contribute significantly to monsoon variability and climate changes. It is also observed that there exists a link between the stratospheric QBO and Indian summer monsoon

Ozone present in the atmosphere not only absorbs the biologically harmful ultraviolet radiation but also is an important ingredient of the climate system. The radiative absorption properties of ozone make it a determining factor in the structure of the atmosphere. Ozone in the troposphere has many negative impacts on humans and other living beings. Another significant aspect is the absorption of outgoing infrared radiation by ozone thus acting as a greenhouse gas. The variability of ozone in the atmosphere involves many interconnections with the incoming and outgoing radiation, temperature circulation etc. Hence ozone forms an important part of chemistry-climate as well as radiative transfer models. This aspect also makes the quantification of ozone more important. The discovery of Antarctic ozone hole and the role of anthropogenic activities in causing it made it possible to plan and implement necessary preventive measures. Continuous monitoring of ozone is also necessary to identify the effect of these preventive steps. The reactions involving the formation and destruction of ozone are influenced significantly by the temperature fluctuations of the atmosphere. On the other hand the variations in ozone can change the temperature structure of the atmosphere. Indian subcontinent is a region having large weather and climate variability which is evident from the large interannual variability of monsoon system over the region. Nearly half of Indian region comprises the tropical region. Most of ozone is formed in the tropical region and transported to higher latitudes. The formation and transport of ozone can be influenced by changes in solar radiation and various atmospheric circulation features. Besides industrial activities and vehicular traffic is more due to its large population. This may give rise to an increase in the production of tropospheric ozone which is greenhouse gas. Hence it becomes necessary to monitor the atmospheric ozone over this region. This study probes into the spatial distribution and temporal evolution of ozone over Indian subcontinent and discusses the contributing atmospheric parameters.

Some study has been made earlier, but no attempt has ever been made to make the study comprehensive and comparative. There exists also no information as to the working of the system. Hence the work is undertaken to provide first hand knowledge of the legal institutions that had handled and now handles annually large masses of deprived and neglected population. An investigation is also necessary to know the legal and social characteristics of the jurisdiction enjoined on the court so that this will help compare the law in the statute with the law and practice. The evaluation of the working system in the changed social atmosphere is also an urgent need of the hour

Academic libraries worldwide have witnessed a number of trends and paradigm shifts over the last decade. It is vital for university libraries to develop a collection of high standards to satisfy academics and researchers for supporting the vision and mission of a university. The area of collection development and management is the most important part of any library. This paper reports on the problems and prospects of collection and asset management of the University Library of Cochin University of Science and Technology (CUSAT). The insight for the paper comes from the authors’ first-hand experience supported by literature review. Detailed information regarding the purchase of books, serials, policies regarding the acquisition, and changing trends and problems were collected from the official records with the help of a structured data sheet. The study discovers the current trends in collection and asset management in CUSAT and point out the changes likely to be adopted in future.

In drawing a conclusion for this study, care must be taken in generalizing findings since the population of students and teachers investigated were limited to certain levels in the different schools and countries. This study recognized some complexity of the factors underlying the status of school gardening instruction and activities in Germany, Nigeria and the U.S. as inadequate time for decision-making in the process of gardening, motivation of teachers and students. This was seen as the major impediments that influenced the status of gardening in the three countries. However, these factors were considered to have affected students’ mode of participation in the school gardening projects. This research finding suggests that the promotion and encouragement of students in gardening activities will promote vegetable production and increasing the numbers of practical farmers. Gardening has the potential to create opportunities for learning in an environment where children are able to experience nature first hand and to use the shared experience for communication (Bowker & Tearle, 2007). Therefore, the need for students to be encouraged to participate in gardening programs as the benefit will not only reduce the rate of obesity currently spreading among youths, but will contribute to the improve knowledge on science subjects. To build a network between community, parents and schools, a parent’s community approach should be used as the curriculum. The community approach will tighten the link between schools; community members, parents, teachers and students. This will help facilitate a better gardening projects implementation. Through a close collaboration, teachers and students will be able to identify issues affecting communities and undertake action learning in collaboration with community organizations to assess community needs and plan the implementation strategies as parents are part of the community. The sense of efficacy is a central factor in motivational and learning processes that govern educational improvement, standard and performance on complex tasks of both teachers and students. Dedication and willingness are the major stimulator and achievement of a project. Through a stimulator and provision of incentives and facilities, schools can achieve the best in project development. Teachers and principals should be aware that students are the lever for achieving the set goals in schools. Failure to understand what students need will result in achieving zero result. Therefore, it is advised that schools focus more on how to lure students to work through proper collaboration with the parents and community members. Principals and teachers should identify areas where students need to be corrected, helping them to correct the problem will enable them be committed in the schools’ programs.

Many plant strengtheners are promoted for their supposed effects on nutrient uptake and/or resistance induction (IR). In addition, many organic fertilizers are supposed to enhance plant health and several studies have shown that tomatoes grown organically are more resistant to late blight, caused by Phytophthora infestans to tomatoes grown conventionally. Much is known about the mechanisms underlying IR. In contrast, there is no systematic knowledge about genetic variation for IR. Therefore, the following questions were addressed in the presented dissertation: (i) Is there genetic variation among tomato genotypes for inducibility of resistance to P. infestans? (ii) How do different PS compare with the chemical inducer BABA in their ability to IR? (iii) Does IR interact with the inducer used and different organic fertilizers? A varietal screening showed that contrary to the commonly held belief IR in tomatoes is genotype and isolate specific. These results indicate that it should be possible to select for inducibility of resistance in tomato breeding. However, isolate specificity also suggests that there could be pathogen adaptation. The three tested PS as well as two of the three tested organic fertilisers all induced resistance in the tomatoes. Depending on PS or BABA variety and isolate effects varied. In contrast, there were no variety and isolate specific effects of the fertilisers and no interactions with the PS and fertilisers. This suggests that the different PS should work independent of the soil substrate used. In contrast the results were markedly different when isolate mixtures were used for challenge inoculations. Plants were generally less susceptible to isolate mixtures than to single isolates. In addition, the effectiveness of the PS was greater and more similar to BABA when isolate mixtures were used. The fact that the different PS and BABA differed in their ability to induce resistance in different host genotype -pathogen isolate combinations puts the usefulness of IR as a breeding goal in question. This would result in varieties depending on specific inducers. The results with the isolate mixtures are highly relevant. On the one hand they increase the effectiveness of the resistance inducers. On the other hand, measures that increase the pathogen diversity such as the use of diversified host populations will also increase the overall resistance of the hosts. For organic tomato production the results indicate that it is possible to enhance the tomato growing system with respect to plant health management by using optimal fertilisers, plant strengtheners and any measures that increase system diversity.

The basic idea behind improving local food security consists of two paths; first, accessibility (price, stock) and second, availability (quantity and biodiversity); both are perquisites to the provision of nutrients and a continuous food supply with locally available resources. The objectives of this thesis are to investigate if indigenous knowledge still plays an important role in traditional farming in the Minangkabau`s culture, thus supporting local food security. If the indigenous knowledge still plays a role in food culture in the Minangkabau`s culture which is linked to the matrilineal role and leads to a sound nutrition. Further, it should be tested if marantau influences traditional farming and food culture in Minangkabau`s, and if the local government plays a role in changing of traditional farming systems and food culture. Furthermore this thesis wants to prove if education and gender are playing a role in changing traditional farming system and food culture, and if the mass media affects traditional farming systems and food culture for the Minangkabau. The study was completed at four locations in West Sumatera; Nagari Ulakan (NU) (coastal area), Nagari Aia Batumbuak (NAB) (hilly area), Nagari Padang Laweh Malalo (NPLM) (lake area), Nagari Pandai Sikek (NPS) (hilly area). The rainfall ranged from 1400- 4800 mm annually with fertile soils. Data was collected by using PRA (Participatory Rural Appraisal) to investigate indigenous knowledge (IK) and its interactions, which is also combining with in depth-interview, life history, a survey using semi-structured-questionnaire, pictures, mapping, and expert interview. The data was collected from June - September 2009 and June 2010. The materials are; map of area, list of names, questionnaires, voices recorder, note book, and digital camera. The sampling method was snowball sampling which resulted in the qualitative and quantitative data taken. For qualitative data, ethnography and life history was used. For quantitative, a statistical survey with a semi-structured questionnaire was used. 50 respondents per each site participated voluntarily. Data was analyzed by performing MAXQDA 10, and F4 audio analysis software (created and developed by Philip-University Marburg). The data is clustered based on causality. The results show that; the role of IK on TFS (traditional farming system) shown on NPLM which has higher food crop biodiversity in comparison to the other three places even though it has relatively similar temperature and rainfall. This high food crop biodiversity is due to the awareness of local people who realized that they lived in unfavourable climate and topography; therefore they are more prepared for any changes that may occur. Carbohydrate intake is 100 % through rice even though they are growing different staple crops. Whereas most of the people said in the interviews that not eating rice is like not really eating for them. In addition to that, mothers still play an important role in kitchen activities. But when the agriculture income is low, mothers have to decide whether to change the meals or to feel insecure about their food supply. Marantau yields positive impact through the remittances it provides to invest on the farm. On the other hand, it results in fewer workers for agriculture, and therefore a negative impact on the transfer of IK. The investigation showed that the local government has a PTS (Padi Tanam Sabatang) programme which still does not guarantee that the farmers are getting sufficient revenue from their land. The low agricultural income leads to situation of potential food insecurity. It is evident that education is equal among men and women, but in some cases women tend to leave school earlier because of arranged marriages or the distances of school from their homes. Men predominantly work in agriculture and fishing, while women work in the kitchen. In NAB, even though women work on farmland they earn less then men. Weaving (NPS) and kitchen activity is recognized as women’s work, which also supports the household income. Mass media is not yielding any changes in TFS and food culture in these days. The traditional farming system has changed because of intensive agricultural extension which has introduced new methods of agriculture for the last three decades (since the 1980’s). There is no evidence that they want to change any of their food habits because of the mass media despite the lapau activity which allows them to get more food choices, instead preparing traditional meal at home. The recommendations of this thesis are: 1) The empowerment of farmers. It is regarding the self sufficient supply of manure, cooperative seed, and sustainable farm management. Farmers should know – where are they in their state of knowledge – so they can use their local wisdom and still collaborate with new sources of knowledge. Farmers should learn the prognosis of supply and demand next prior to harvest. There is a need for farm management guidelines; that can be adopted from both their local wisdom and modern knowledge. 2) Increase of non-agricultural income Increasing the non-agricultural income is strongly recommended. The remittances can be invested on non-agricultural jobs. 3) The empowerment of the mother. The mother plays an important role in farm to fork activities; the mother can be an initiator and promoter of cultivating spices in the backyard. Improvement of nutritional knowledge through information and informal public education can be done through arisan ibu-ibu and lapau activity. The challenges to apply these recommendations are: 1) The gap between institutions and organizations of local governments. There is more than one institution involved in food security policy. 2) Training and facilities for field extension agriculture (FEA) is needed because the rapid change of interaction between local government and farmer’s dependent on this agency.

Die vorliegende Arbeit beschäftigt sich mit der Besteuerung der öffentlichen Hand an Personenhandelsgesellschaften. Hierbei wird der Frage nach der steuerrechtlichen Beurteilung einer solchen nachgegangen. Es wird hinterfragt, ob die in der Rechtsprechung, Verwaltungsanweisungen und Richtlinien der Finanzverwaltung sowie der Literatur vertretenen Auffassungen haltbar sind oder ob diese revidiert werden müssen. Hierzu werden im ersten Teil der Arbeit die theoretischen Grundlagen der sowohl rechtlichen als auch ökonomischen Problemfelder erarbeitet. Auf dieser Grundlage werden die Sichtweise der Rechtsprechung, Verwaltungsvorschriften und Richtlinien der Finanzverwaltung sowie der einschlägigen Literatur kritisch evaluiert und im Hinblick auf Unstimmigkeiten und sich daran anschließenden Gestaltungsbedarf untersucht. Im zweiten der Teil der Arbeit werden die im ersten Teil gefundenen Ergebnisse und Erkenntnisse anhand von ausgewählten Fällen diskutiert und aus diesen ökonomische und rechtlich abgesicherte Gestaltungsoptionen abgeleitet. Im dritten Teil der Arbeit werden die Kernaussagen zusammengefasst und die zentralen Ergebnisse aufgelistet. Im Abschließenden Ausblick werden die Mängel des Jahresteuergesetzes 2009 in Bezug auf die Personenhandelsgesellschaften an denen die öffentliche Hand beteiligt ist im Hinblick auf die steuerlichen Regelungen in Verbindung mit dem Anwendnungserlass des BMF gerügt.

This paper describes a trainable system capable of tracking faces and facialsfeatures like eyes and nostrils and estimating basic mouth features such as sdegrees of openness and smile in real time. In developing this system, we have addressed the twin issues of image representation and algorithms for learning. We have used the invariance properties of image representations based on Haar wavelets to robustly capture various facial features. Similarly, unlike previous approaches this system is entirely trained using examples and does not rely on a priori (hand-crafted) models of facial features based on optical flow or facial musculature. The system works in several stages that begin with face detection, followed by localization of facial features and estimation of mouth parameters. Each of these stages is formulated as a problem in supervised learning from examples. We apply the new and robust technique of support vector machines (SVM) for classification in the stage of skin segmentation, face detection and eye detection. Estimation of mouth parameters is modeled as a regression from a sparse subset of coefficients (basis functions) of an overcomplete dictionary of Haar wavelets.

The implementation of anti-drug policies that focus on illicit crops in the Andean countries faces many significant obstacles, one of which is the cultural clash it generates between the main stakeholders. On the one hand one finds the governments and agencies that attempt to implement crop substitution and eradication policies and on the other the peasant and natives communities that have traditionally grown and used coca or those peasants who have found in coca an instrument of power and political leverage that they never had before. The confrontation about coca eradication, alternative development and other anti-drug policies in coca growing areas transcends drug related issues and is part of a wider and deeper confrontation that reflects the long-term unsolved conflicts of the Andean societies. All Andean countries have stratified and fragmented societies in which peasants and Indians have been excluded from power. In Bolivia, Ecuador and Peru most peasants belong to native communities many of which have remained segregated from “white” society. The mixing of the races (mestizaje) in Colombia occurred early during the Conquest and Colony. Those of Indian descent became subservient to the Spanish and Creoles. The society that evolved was (and still is) highly hierarchical, authoritarian, and has subjacent racist values. The resulting political system has been exclusionary of large portions of the population. Among Indian communities coca has been used for millennia and its use has become an identity symbol of their resistance against what may be looked at as foreign invasion. “The Andean Indian chews coca because that way he affirms his identity as son and owner of the land that yesterday the Spaniard took away and today the landowner keeps away from him. To chew coca is to be Indian...and to quietly and obstinately challenge the contemporary lords that descend from the old encomenderos and the older conquistadors” (Vidart, 1991: 61, author’s translation). In Andean literature on illegal drugs as well as in seminars, colloquia and other meetings where drug policies are debated, complaints are frequently expressed about the treatment of coca in the same category as cocaine, heroin, morphine amphetamines and other “hard” drugs. The complainants assert that “coca is not cocaine” and that it is unfair to classify coca, a nature given plant which has been used for millennia in the Andes without significant negative effects on users, in the same category as man made psychotropic drugs. They also argue that coca has manifold social and religious meanings in indigenous cultures, that coca is sacred and that the requirement of the1961 Single Convention demanding that Bolivia and Peru completely eradicate coca within 25 years is limiting Indigenous communities in their freedom to practice their religions. In most debates about drug interdiction, the views of those who oppose that approach are not accepted as legitimate. Indeed, “prohibitionists” demonize drugs and those who oppose drug policies in Latin America frequently demonize the United States as the imperialist power that imposes them. This dual polarization is a main obstacle to establish a meaningful policy debate aimed at broadening the policy consensus necessary for successful policy implementation. This essay surveys the status of coca in the United Nations Conventions, explains why it is confusing, and how a few changes would eliminate some of the sources of conflict and help organize and control licit coca markets in the Andes. The current disorganized and weakly controlled legal coca market in Peru has been analyzed to demonstrate its deficiencies and to illustrate possible improvements in international drug control policies.
