Institutional environment in North Korea: market structure and overcoming institutional voids

Tutkimus sai innoituksensa, kun tutkija huomasi tarpeen liiketaloudelliselle, ajantasaiselle ja realistiselle tutkimukselle Pohjois-Korean markkinoista, joka kuvailisi markkinoiden olemassaolevia ja puuttuvia rakenteita sekä tutkisi mahdollisuuksia ylittää puuttuvat rakenteet. Institutionaalinen teoria valittiin sopivaksi viitekehykseksi kuvailla ja tutkia markkinarakennetta. Tutkimuskysymys muotoiltiin seuraavasti: “Miten ulkomaiset yritykset voivat reagoida puuttuviin markkinarakenteisiin Pohjois-Koreassa?”. Tutkimuskysymys jaettiin kolmeen osakysymykseen: (1) Millainen on Pohjois-Korean markkinoiden institutionaalinen ympäristö? (2) Mitkä ovat merkittävimmät puuttuvat markkinarakenteet Pohjois-Koreassa? (3) Mitä mahdollisuuksia ulkomaisilla yrityksillä voisi olla reagoida puuttuviin markkinarakenteisiin? Tutkimus toteutettiin kvalitatiivisena, koska tutkimuskysymys on deskriptiivinen. Aineisto kerättiin asiantuntijahaastattelun ja kvalitatiivisen sisällönanalyysin keinoin. Primääriaineiston muodostavat 2 asiantuntijahaastattelua ja sekundääriaineiston muodostavat 95 artikkelia, jotka kerättiin 40 lähteestä. Aineisto analysoitiin kvalitatiivisen sisällönanalyysin keinoin. Aineisto koodattiin, luokiteltiin ja esitettiin kokonaisuuksina luokittelurungon avulla, joka laadittiin tutkimusta varten muodostetun teoreettisen viitekehyksen mukaan. Tulokset ja johtopäätökset voidaan tiivistää seuraavasti. (1) Pohjois-Korean markkinan instituutioihin vaikuttaa kaksoisrakenne, jossa muodollinen, sosialistinen rakenne ja epämuodollinen, markkinalähtöinen rakenne toimivat päällekkäin. (2) Puuttuvia rakenteita on sekä markkinan kontekstissa että markkinatasolla. Puutteet ovat osittain seurausta vanhojen rakenteiden korvaantumisesta uusilla, jotka eivät ole institutionalisoituneet. (3) Yritykset voivat käyttää samoja mahdollisuuuksia reagoida puuttuviin markkinarakenteisiin Pohjois-Koreassa, joita kehittyvien markkinoiden yhteydessä on esitetty. Sen tulkittiin vähentävän käsitystä, jonka mukaan Pohjois-Korean markkina on liian erikoinen yritystoiminnalle. (4) Kasvava keskiluokka sekä yrittäjyyden ja naisten yhä merkittävämpi rooli liike-elämässä aiheuttavat alhaalta ylöspäin suuntautuvaa kehitystä markkinoilla. Nämä ovat merkkejä viimeaikaisesta kehityksestä, jotka eivät ole saaneet laajaa huomiota länsimaisessa mediassa. Se korostaa tarvetta liiketaloudelliselle, ajantasaiselle jatkotutkimukselle Pohjois-Korean markkinoista.

Institutional environment in North Korea: market structure and overcoming institutional voids

The research was sparked by an exchange in South Korea, as the author identified a gap in research that provides economic, up to date and realistic information about the North Korean market in English language. A need for a research was identified that would describe the market’s existing and missing market structures and explore possibilities to overcome the missing market structures. Institutional theory was chosen as a suitable framework to describe and explore the market. The research question was formulated as follows: “How can foreign companies overcome institutional voids in the North Korean market?”. To answer the research question, it was divided into three sub-questions as follows: (1) What is the institutional environment in North Korea like? (2) What are the major institutional voids in the North Korean market? (3) What possibilities do foreign companies have to overcome institutional voids? The research is qualitative by nature due to the descriptive and exploratory nature of the research question. Data collection consisted of expert interview and content analysis, resulting in primary data of two interviews and secondary data of 95 articles from 40 different sources. The data was analyzed with the systematical technique of content analysis. The data was coded, classified and presented as concepts with the help of a classification system that was build following the theoretical framework adapted for this study. The findings can be summarized as follows. (1) The market institutions are characterized by an overlapping dual system of formal, socialist structures and informal, market-oriented structures. (2) Institutional voids prevail on both the market’s contextual and on the market level. They are partly result of old institutions being replaced by new institutions that lack institutionalization. (3) Identified possibilities to overcome institutional voids correspond with possibilities drawn from previous research. This decreases the image of North Korea as an impossibly unique market to operate in. (4) Emerging middle class, rapidly growing entrepreneurial activities and women’s increasing role in business drive a down-to-up change in the market. This signals the recent development of the market, yet has been overlooked in the Western media. Thus there is a need for further economic, up to date research concerning North Korea.

Content-centered method for search engine optimization

Value of online business has grown to over one trillion USD. This thesis is about search engine optimization, which focus is to increase search engine rankings. Search engine optimization is an important branch of online marketing because the first page of search engine results is generating majority of the search traffic. Current articles about search engine optimization and Google are indicating that with the proper use of quality content, there is potential to improve search engine rankings. However, the existing search engine optimization literature is not noticing content at a sufficient level. To decrease that difference, the content-centered method for search engine optimization is constructed, and content in search engine optimization is studied. This content-centered method consists of three search engine optimization tactics: 1) content, 2) keywords, and 3) links. Two propositions were used for testing these tactics in a real business environment and results are suggesting that the content-centered method is improving search engine rankings. Search engine optimization is constantly changing because Google is adjusting its search algorithm regularly. Still, some long-term trends can be recognized. Google has said that content is growing its importance as a ranking factor in the future. The content-centered method is taking advance of this new trend in search engine optimization to be relevant for years to come.

Drumming toward communitas : a case study of facilitated recreational music making and the Arthurian method

The phenomenon of communitas has been described as a moment 'in and out of time' in which a collective of individuals may be experienced by one as equal and individuated in an environment stripped of structural attributes (Turner, 1 969). In these moments, emotional bonds form and an experience of perceived 'oneness' and synergy may be described. As a result of the perceived value of these experiences, it has been suggested by Sharpe (2005) that more clearly understanding how this phenomenon may be purposefully facilitated would be beneficial for leisure service providers. Consequently, the purpose of this research endeavor was to examine the ways in which a particular leisure service provider systematically employs specific methods and sets specific parameters with the intention of guiding participants toward experiences associated with communitas or "shared spirit" as described by the organization. A qualitative case study taking a phenomenological approach was employed in order to capture the depth and complexity of both the phenomenon and the purposefiil negotiation of experiences in guiding participants toward this phenomenon. The means through which these experiences were intentionally facilitated was recreational music making in a group drumming context. As such, an organization which employs specific methods of rhythm circle facilitation as well as trains other facilitators all over the world was chosen purposely for their recognition as the most respectable and credible in this field. The specific facilitator was chosen based on high recommendation by the organization due to her level of experience and expertise. Two rhythm circles were held, and participants were chosen randomly by the facilitator. Data was collected through observation in the first circle and participant- observation in the second, as well as through focus groups with circle participants. Interviews with the facilitator were held both initially to gain broad understanding of concepts and phenomenon as well as after each circle to reflect on each circle specifically. Data was read repeatedly to drawn out patterns which emerged and were coded and organized accordingly. It was found that this specific process or system of implementation lead to experiences associated with communitas by participants. In order to more clearly understand this process and the ways in which experiences associated with communitas manifest as a result of deliberate facilitator actions, these objective facilitator actions were plotted along a continuum relating to subjective participant experiences. These findings were then linked to the literature with regards to specific characteristics of communitas. In so doing, the intentional manifestation of these experiences may be more clearly understood for ftiture facilitators in many contexts. Beyond this, findings summarized important considerations with regards to specific technical and communication competencies which were found to be essential to fostering these experiences for participants within each group. Findings surrounding the maintenance of a fluid negotiation of certain transition points within a group rhythm event overall were also highlighted, and this fluidity was found to be essential to the experience of absorption and engagement in the activity and experience. Emergent themes of structure, control, and consciousness have been presented as they manifested and were found to affect experiences within this study. Discussions surrounding the ethics and authenticity of these particular methods and their implementation has also been generated throughout. In conclusion, there was a breadth as well as depth of knowledge found in unpacking this complex process of guiding individuals toward experiences associated with communitas. The implications of these findings contribute in broadening the current theoretical as well as practical understanding as to how certain intentional parameters may be set and methods employed which may lead to experiences of communitas, and as well contribute a greater knowledge to conceptualizing the manifestation of these experiences when broken down.

The design, synthesis and characterization of new building blocks for the preparation of molecule-based magnetic materials /

Two new families of building blocks have been prepared and fully characterized and their coordination chemistry exploited for the preparation of molecule-based magnetic materials. The first class of compounds were prepared by exploiting the chemistry of 3,3'-diamino-2,2'-bipyridine together with 2-pyridine carbonyl chloride or 2-pyridine aldehyde. Two new ligands, 2,2'-bipyridine-3,3'-[2-pyridinecarboxamide] (Li, 2.3) and N'-6/s(2-pyridylmethyl) [2,2'bipyridine]-3,3'-diimine (L2, 2.7), were prepared and characterized. For ligand L4, two copper(II) coordination compounds were isolated with stoichiometrics [Cu2(Li)(hfac)2] (2.4) and [Cu(Li)Cl2] (2.5). The molecular structures of both complexes were determined by X-ray crystallography. In both complexes the ligand is in the dianionic form and coordinates the divalent Cu(II) ions via one amido and two pyridine nitrogen donor atoms. In (2.4), the coordination geometry around both Cu11 ions is best described as distorted trigonal bipyramidal where the remaining two coordination sites are satisfied by hfac counterions. In (2.5), both Cu(II) ions adopt a (4+1) distorted square pyramidal geometry. One copper forms a longer apical bond to an adjacent carbonyl oxygen atom, whereas the second copper is chelated to a neighboring Cu-Cl chloride ion to afford chloride bridged linear [Cu2(Li)Cl2]2 tetramers that run along the c-axis of the unit cell. The magnetic susceptibility data for (2.4) reveal the occurrence of weak antiferromagnetic interactions between the copper(II) ions. In contrast, variable temperature magnetic susceptibility measurements for (2.5) reveal more complex magnetic properties with the presence of ferromagnetic exchange between the central dimeric pair of copper atoms and weak antiferromagnetic exchange between the outer pairs of copper atoms. The Schiff-base bis-imine ligand (L2, 2.7) was found to be highly reactive; single crystals grown from dry methanol afforded compound (2.14) for which two methanol molecules had added across the imine double bond. The susceptibility of this ligand to nucleophilic attack at its imine functionality assisted via chelation to Lewis acidic metal ions adds an interesting dimension to its coordination chemistry. In this respect, a Co(II) quaterpyridine-type complex was prepared via a one-pot transformation of ligand L2 in the presence of a Lewis acidic metal salt. The rearranged complex was characterized by X-ray crystallography and a reaction mechanism for its formation has been proposed. Three additional rearranged complexes (2.13), (2.17) and (2.19) were also isolated when ligand (L2, 2.7) was reacted with transition metal ions. The molecular structures of all three complexes have been determined by X-ray crystallography. The second class of compounds that are reported in this thesis, are the two diacetyl pyridine derivatives, 4-pyridyl-2,6-diacetylpyridine (5.5) and 2,2'-6,6'-tetraacetyl-4,4'-bipyridine (5.15). Both of these compounds have been designed as intermediates for the metal templated assembly of a Schiff-base N3O2 macrocycle. From compound (5.15), a covalently tethered dimeric Mn(II) macrocyclic compound of general formula {[Mn^C^XJCl-FkO^Cl-lO.SFbO (5.16) was prepared and characterized. The X-ray analysis of (5.16) reveals that the two manganese ions assume a pentagonal-bipyramidal geometry with the macrocycle occupying the pentagonal plane and the axial positions being filled by a halide ion and a H2O molecule. Magnetic susceptibility data reveal the occurrence of antiferromagnetic interactions between covalently tethered Mn(II)-Mn(II) dimeric units. Following this methodology a Co(II) analogue (5.17) has also been prepared which is isostructural with (5.16).

A study of self-directed learning at an Ontario college of applied arts and technology

Ontario Colleges of Applied Arts and Technology (CAATs) are currently in the process of restructuring to ensure quality, accountability, and accessibility of college education. References to learner involvement and self-directed learning are prevalent. "Alternative delivery" and "paradigm shift" are current buzzwords within the Ontario CAAT system as an environment is created supportive of change. Instability of funding has also dictated a need for change. Therefore, a focus has become quality of learning with less demand on public resources. This qualitative case study was conducted at an Ontario CAAT to gather descriptive, perceptual data from post-secondary community college educators who were identified as supportive of self-directed learning and from post-secondary, traditional-aged college students who were perceived by their educators to be selfdirected learners. This college was selected because of initiatives to modify its academic paradigm to encourage what was reputed in the Ontario CAAT system to be self-directed learning. The purpose of this study was to investigate how postsecondary, traditional-aged college students and their educators perceive self-directed learning as part of the teaching-learning experience within a community college setting. Educator participants of the study were selected based on the results of a teaching and learning survey intended to identify educators supportive of self-directed learning. A total of 317 surveys were distributed to every full-time educator at the sample college; 192 completed surveys were returned for a return rate of 61 %. Of these, 8% indicated instructional beliefs and values supportive of self-directed learning. A purposive sample of six educators was selected using a maximulp variation sampling strategy. A network selection sampling strategy was used to select a purposive sample of seven post-secondary students who were identified by the sample educators as selfdirected learners. The results of the study show that students and educators have similar perspectives and operating definitions of self-directed learning and all participants believe they either practice or facilitate self-directed learning. However, their perspectives and practices are not consistent with the literature which emphasizes learner autonomy or control in course structure and content. A central characteristic of the participants represented in this study is the service-oriented professions with which each is associated. Experientiallearning opportunities were highly valued for the options provided in increasing learner independence and competencies in reflective practice. Although there were discrepancies between espoused theory and theory in practice in terms of course structure, the process of self-directed learning was being practiced and supported outside the classroom structure in clinical settings, labs and related experiences.

Sex chromosome translocation and speciation : a Drosophila genetic model

Although exceptions may be readily identified, two generalizations concerning genetic differences among species may be drawn from the available allozyme and chromosome data. First, structural gene differences among species vary widely. In many cases, species pairs do not differ more than intraspecific populations. This suggests that either very few or no gene substitutions are required to produce barriers to reproduction (Avise 1976). Second, chromosome form and/or number differs among even closely related species (White 1963; 1978; Fredga 1977; Wright 1970). Many of the observed chromosomal differences involve translocational rearrangements; these produce severe fitness depression in heterozygotes and were, thus, long considered unlikely candidates for the fixation required of genetic changes leading to speciation (Wright 1977). Nonetheless, the fact that species differences are frequently translocational argues convincingly for their fixation despite prejudices to the contrary. Haldane's rule states that in the F of interspecific crosses, the heterogametic sex is absent or sterile in the preponderance of cases (Haldane 1932). This rule definitely applies in the genus Dr°sophila (Ehrman 1962). Sex chromosome translocations do not impose a fitness depression as severe as that imposed by autosomal translocations, and X-Y translocations may account for Haldane's rule (Haldane 1932). Consequently a study of the fit ness parameters of an X·yL and a yS chromosome in Drosophila melanogaster populations was initiated by Tracey (1972). Preliminary results suggested that x.yL//YSmales enjoyed a mating advantage with X·yL//X·yL females, that this advantage was frequency dependent, that the translocation produced sexual isolation and that interactions between the yL, yS and a yellow marker contributed to the observed isolation (Tracey and Espinet 1976; Espinet and Tracey 1976). Encouraged by the results of these prelimimary studies, further experiments were performed to clarify the genetic nature of the observed sexual isolation, S the reality of the y frequency dependent fitness .and the behavioural changes, if any, produced by the translocation. The results of this work are reported herein. Although the marker genes used in earlier studies, sparkling poliert an d yellow have both been found to affect activity,but only yellow effects asymmetric sexual isolation. In addition yellow effects isolation through an interaction with the T(X-y) chromosomes, yS also effects isolation, and translocational strains are isolated from those of normal karyotype in the absence of marker gene differences. When yS chromosomes are in competition with y chromosomes on an X.yL background, yS males are at a distinct advantage only when their frequency is less than 97%. The sex chromosome translocation alters the normal courtship pattern by the incorporation of circling between vibration and licking in the male repertoire. Finally a model of speciation base on the fixation of this sex chromosome translocation in a geographically isolated gene pool is proposed.

Towards sustainable peace : peace-building and human security

Failed and fragile states that result from intrastate war pose severe threats to the security of both the international system and individual states alike. In the post-Cold War era, the international community has come to recognize the reality of these threats and the difficulty involved in ending violence and building sustainable peace in failed and fragile states. This work focuses upon the development of a comprehensive strategy for sustainable peace-building by incorporating the tenets of the human security doctrine into the peace-building process. Through the use of case studies of The Former Yugoslav Republic of Macedonia and East Timor, the development and refinement of the doctrine of human security will occur, as well as, an understanding of how and where human security fits into the sustainable peace-building equation. The end result of the analysis is the development of a hierarchical pyramid formation that brings together human security and peace-building into one framework that ultimately creates the foundation and structure of sustainable peace-building. With the development of a sustainable peace-building structure based upon the human security doctrine, the role of Canada in the support of sustainable peace-building is analyzed in relation to the form and level of involvement that Canada undertakes and contributes to in the implementation and support of sustainable peace-building initiatives. Following from this, recommendations are provided regarding what role(s) Canada should undertake in the sustainable peace-building process that take into consideration the present and likely future capabilities of Canada to be involved in various aspects of the peace-building process. ii This paper outlines the need for a peace-building strategy that is designed to be sustainable in order that failed and fragile states resulting from intrastate conflict do not regress or collapse back into a condition of civil war, and subsequently designs such a strategy. The linking of peace-building and human security creates the required framework from which sustainable peace-building is derived. Creating sustainable peace is necessary in order to increase the likelihood that both present and future generations existing in failed and fragile states will be spared from the scourge of intrastate war.

Course/instructor evaluation : perspectives of part-time graduate students

This study explored 6 part-time graduate students' perspectives on course/instructor evaluation. The purpose was to explore whether a link exists between the evaluation for course and instructors as contained in the Faculty of Education courselinstructor evaluation form and the needs of part-time students enrolled in that program. The literature review provided contextual information concerning the 3 main subject areas based upon which the research questions were designed: learner needs in the context of part-time graduate students, courselinstructor eval~ation, and the potential lack of congruency between the 2. Using a semistructured interview process, participants identified criteria important or relevant to the evaluation process and incongruent with the course/instructor evaluation form. A qualitative research methodology using a grounded theory approach contributed to the theory on the nature of course evaluation instruments in a graduate program and addressed the notion of where power was situated within the evaluation process. Findings suggested that the concepts of relevance and the instructor's role that participants identified as important in their graduate learning experience were congruent with what they considered important components of the course/instructor evaluation form. Participants noted a lack of congruency between their expectations of a quality graduate learning experience and the format, content, intent, and timing of the evaluation process. The study confirmed that students did want a voice in the evaluation of their learning experience at both the course and program levels.

The Impact of Directed Mirror Focus and Technique Cues on Psychological, Cognitive and Emotional Exercise Correlates in an Introductory Weight Training Orientation

The purpose of the study was to investigate whether teaching inactive and low active women to use mirrors for form and technique purposes could lessen the negative impact of mirrors on self-presentational concerns, affect, and self-efficacy. Eligible women (N = 82) underwent a one-on-one weight training orientation with a personal trainer. Participants were randomized into one of four experimental groups, each unique in the type of feedback (general or technique-specific) and the degree of focus on the mirror for technique reinforcement. Questionnaires assessed study outcomes pre- and post-orientation. Results indicated groups did not significantly differ on any post-condition variables, when controlling for pre-condition values (all p’s >.05). All groups showed outcome improvements following the orientation. This suggests that during a complex task, a personal trainer who emphasizes form and technique can facilitate improvements to psychological outcomes in novice exercisers, independent of the presence of mirrors or directional cues provided.

Exploitation des genres de textes pour assister les pratiques textuelles dans les environnements numériques de travail : le cas du courriel chez des cadres et des secrétaires dans une municipalité et une administration fédérale canadiennes

Notre recherche a pour but de déterminer comment les genres textuels peuvent être exploités dans le design des environnements numériques de travail afin de faciliter l’accomplissement des pratiques textuelles de cadres et de secrétaires dans une municipalité et une administration fédérale canadiennes. À cet effet, le premier objectif consiste à évaluer l’aptitude des environnements numériques de travail à supporter les pratiques textuelles (lecture, écriture et manipulation des textes) de ces employés. Le deuxième objectif est de décrire les rôles des genres textuels au cours des pratiques textuelles. Avec l’exemple du courriel, le troisième objectif vise à examiner comment le genre peut être exploité dans une perspective d’assistance à la réalisation des pratiques textuelles dans les environnements numériques de travail. Cette recherche de nature qualitative comporte une méthodologie en deux étapes. La première étape consiste en un examen minutieux des pratiques textuelles, des difficultés rencontrées au cours de celles-ci, du rôle du genre dans les environnements numériques de travail, ainsi que des indices sollicités au cours de la gestion du courriel. Trois modes de collecte des données qualitatives sont utilisés auprès de 17 cadres et de 17 secrétaires issus de deux administrations publiques : l’entrevue semi-dirigée, le journal de bord et l’enquête cognitive. Les résultats sont examinés à l’aide de stratégies d’analyse de contenu qualitative. La deuxième phase comprend la mise au point d’une chaîne de traitement du courriel, visant à étayer notre réflexion sur le genre textuel et son exploitation dans la conception des environnements numériques de travail. Un corpus de 1703 messages est élaboré à partir d’un échantillon remis par deux cadres gouvernementaux. Les résultats permettent d’abord de dresser un portrait général des pratiques de lecture, d’écriture et de manipulation des textes communes et spécifiques aux cadres et aux secrétaires. L’importance du courriel, qui constitue environ 40% des systèmes notés dans les journaux de bord, est soulignée. Les difficultés rencontrées dans les environnements numériques de travail sont également décrites. Dans un deuxième temps, les rôles du genre au cours des pratiques textuelles sont examinés en fonction d’une matrice tenant à la fois compte de ses dimensions individuelles et collectives, ainsi que de ses trois principales facettes ; la forme, le contenu et la fonction. Ensuite, nous présentons un cadre d’analyse des indices affectant la gestion du courriel qui synthétise le processus d’interprétation des messages par le destinataire. Une typologie des patrons de catégorisation des cadres est également définie, puis employée dans une expérimentation statistique visant la description et la catégorisation automatique du courriel. Au terme de ce processus, on observe des comportements linguistiques marqués en fonction des catégories du courriel. Il s’avère également que la catégorisation automatique basée sur le lexique des messages est beaucoup plus performante que la catégorisation non lexicale. À l’issue de cette recherche, nous suggérons d’enrichir le paradigme traditionnel relevant de l’interaction humain-ordinateur par une sémiotique du genre dans les environnements numériques de travail. L’étude propose également une réflexion sur l’appartenance du courriel à un genre, en ayant recours aux concepts théoriques d’hypergenre, de genre et de sous-genre. Le succès de la catégorisation automatique du courriel en fonction de facettes tributaires du genre (le contenu, la forme et la fonction) offre des perspectives intéressantes sur l’application de ce concept au design des environnements numériques de travail en vue de faciliter l’accomplissement des pratiques textuelles par les employés.

Web2.0, knowledge sharing and privacy in E-learning

Quand le E-learning a émergé il ya 20 ans, cela consistait simplement en un texte affiché sur un écran d'ordinateur, comme un livre. Avec les changements et les progrès dans la technologie, le E-learning a parcouru un long chemin, maintenant offrant un matériel éducatif personnalisé, interactif et riche en contenu. Aujourd'hui, le E-learning se transforme de nouveau. En effet, avec la prolifération des systèmes d'apprentissage électronique et des outils d'édition de contenu éducatif, ainsi que les normes établies, c’est devenu plus facile de partager et de réutiliser le contenu d'apprentissage. En outre, avec le passage à des méthodes d'enseignement centrées sur l'apprenant, en plus de l'effet des techniques et technologies Web2.0, les apprenants ne sont plus seulement les récipiendaires du contenu d'apprentissage, mais peuvent jouer un rôle plus actif dans l'enrichissement de ce contenu. Par ailleurs, avec la quantité d'informations que les systèmes E-learning peuvent accumuler sur les apprenants, et l'impact que cela peut avoir sur leur vie privée, des préoccupations sont soulevées afin de protéger la vie privée des apprenants. Au meilleur de nos connaissances, il n'existe pas de solutions existantes qui prennent en charge les différents problèmes soulevés par ces changements. Dans ce travail, nous abordons ces questions en présentant Cadmus, SHAREK, et le E-learning préservant la vie privée. Plus précisément, Cadmus est une plateforme web, conforme au standard IMS QTI, offrant un cadre et des outils adéquats pour permettre à des tuteurs de créer et partager des questions de tests et des examens. Plus précisément, Cadmus fournit des modules telles que EQRS (Exam Question Recommender System) pour aider les tuteurs à localiser des questions appropriées pour leur examens, ICE (Identification of Conflits in Exams) pour aider à résoudre les conflits entre les questions contenu dans un même examen, et le Topic Tree, conçu pour aider les tuteurs à mieux organiser leurs questions d'examen et à assurer facilement la couverture des différent sujets contenus dans les examens. D'autre part, SHAREK (Sharing REsources and Knowledge) fournit un cadre pour pouvoir profiter du meilleur des deux mondes : la solidité des systèmes E-learning et la flexibilité de PLE (Personal Learning Environment) tout en permettant aux apprenants d'enrichir le contenu d'apprentissage, et les aider à localiser nouvelles ressources d'apprentissage. Plus précisément, SHAREK combine un système recommandation multicritères, ainsi que des techniques et des technologies Web2.0, tels que le RSS et le web social, pour promouvoir de nouvelles ressources d'apprentissage et aider les apprenants à localiser du contenu adapté. Finalement, afin de répondre aux divers besoins de la vie privée dans le E-learning, nous proposons un cadre avec quatre niveaux de vie privée, ainsi que quatre niveaux de traçabilité. De plus, nous présentons ACES (Anonymous Credentials for E-learning Systems), un ensemble de protocoles, basés sur des techniques cryptographiques bien établies, afin d'aider les apprenants à atteindre leur niveau de vie privée désiré.

Adorno et le projet d'une théorie dialectique de l'oeuvre d'art

Le projet d’une théorie dialectique de l’œuvre d’art est sans doute un des plus complexes que Theodor Adorno ait tenu en haleine, projet qui table sur les horizons théoriques les plus diversifiés du philosophe de Francfort. Il ne s’agit donc pas ici d’en résumer la pertinence et les prémisses, de rendre justice à sa pleine complexité. Ce que je propose bien plutôt de faire c’est de développer trois façons inter-reliées de comprendre ce projet. En partant d’abord de la situation de l’esthétique contemporaine à Adorno, nous voudrions regarder en face la solution qu’offre la Théorie esthétique pour revitaliser l’esthétique philosophique. Il s’agit donc d’abord de questionner les catégories traditionnelles de l’esthétique qui semblent inadéquates à la réalité de l’art moderne « à l’époque où il devient objet de réflexion ». Le second aspect concerne l’interprétation et la méthode de présentation. « L’essai comme forme » qu’Adorno exécute et développe de pair avec la tendance parataxique de la poésie d’Hölderlin est l’objet des Notes sur la littérature. Ces travaux font écho à des notions clefs de la Théorie esthétique, déjà en germes dans « L’actualité de la philosophie » : l’interprétation, le contenu de vérité et le caractère énigmatique. Je propose finalement de restituer une certaine évolution du matériau-dissonance, ce qui recoupe et « matérialise » les deux premières perspectives.
