Full textAfter having been pressed into clay, inscribed on papyrus and printed on paper writing, which dates back to about 3000 B. C. Has now found a new medium thanks to computer technology. The study of usages by staffs in tertiary industries leads to a dual approach. On one hand what is generally known as cognitive technology deals with the impact of electronic writing on the mechanics of learning and thinking, interacting with the development of professional knowledge. On the other hand communication technology deals with temporal and spatial issues, directly interacting with work environment

Full textThis dissertation brings to the forefront the informational and communicational aspects of strategic alliances. It examines how different stages of the lifecycle of an alliance are influenced by the communication capabilities of the partners and the interface through which the partners interact. More specifically, the dissertation investigates (i) the impact of firms’ ability to exchange a large information amount (IT capability) on the alliance design, and in particular on the governance structure and the alliance scope, (ii) the choice between information amount and information richness in alliances, (iii) how this choice influences changes in the levels of trust between the partners, and (iv) implications of the above for alliance performance. These issues are examined by extending existing communication media theories to the domain of interorganizational communication and by combining them with contractual and competence perspectives. Evidence for the arguments is provided from a mix of survey and qualitative data. The survey data were collected from two groups of people: Full members of the Association of Strategic Alliance Professionals and alumni participants of the INSEAD executive program on strategic alliances. The qualitative data were collected through face-to-face interviews with key informants

Full textContributions due to the use, by firms, of new information and communication technologies, can be observed from two main levels. On one hand, firms tend to re-structure their communication systems and channels, both inside and outside. These are basic structural changes, since they tend to transform the stages of the production process, as well as the internal organization of the working groups involved. On the other hand, telecommunication infrastructures are extending the economic environment of the industrial organizations as they provide them with a kind of transparency -in terms of information. Combining these two viewpoints makes possible an original analytical approach of the present network of local activity
Le, Hir Boris. "Capturing Information and Communication Technologies as a General Purpose Technology." Thesis, Châtenay-Malabry, Ecole centrale de Paris, 2012. http://www.theses.fr/2012ECAP0046/document.
Full textThis thesis aims to study Information and Communication Technologies (ICT) as a General Purpose Technology (GPT) and their role in the labor productivity evolution in the United States and Europe during recent decades. This thesis is organized in three parts corresponding to the fundamental GPT features: the wide possibilities for development, the ubiquity of the technology and the ability to create large technological opportunities. The first part depicts, at first, the innovation in ICT, beginning with a short historical review of ICT inventions followed by the analysis of current data on innovation in this field. In particular, it shows how the US was better than the European countries in inventing ICT until now. Second, this first part makes an inventory of measurement difficulties due to the rate and the nature of the change created by such technologies. The second part of the thesis deals with the ubiquitous nature of ICT. It first describes the ICT diffusion across countries and industries and reviews the economic literature on the direct contribution of ICT on labor productivity growth in the US and Europe. The next chapter studies the factor demand's behaviour in sectors that are either ICT producers or ICT intensive users. The third part focuses on the ICT ability to create opportunities for complementarity innovations. Firstly, it identifies the nature of ICT complementary innovations and the corresponding efforts. It shows, then, that national accounts must be improved in order to take these efforts into account as investments. Secondly, this part shows that, among the eleven European countries studied, the problem is highly concentrated in a few countries that invest less both in ICT and in innovative assets and that these two types of effort are complementary

Full textThe business environment at the end of the 20th century requires that corporations should efficiently manage their information ressources, to wich purpose new information technologies (nit : informatics and telecommunications) can be a great help. However, it is not the present business environment justifies the importance of information ressources, we may add further reason, of genial and technological character. From a general point of view, it may be said that the importance of information within the firms is but me reflection on such social organizations of something that is changing at a global level, wich is said to be entering a new order that has been termed as postindustrial society, or information society amongst other definitions. Nevertheless, in the information society, changes in organizations caused by the introduction of new information technologies are inevitable as organizations are compelled by external environment to be efficient and competitive in order to survive. On a technological level, the progress and generalization of the so-called new information technologies have also played a major role in conferring information ressources me strategic character they possess within organizations. Once mis has been said, one of the purpose of our work is to present our hypothesis that the role to be played by new information technologies within thes organizations should consist on puttin the power of these technologies at the service of an efficient management of information ressources, thus opening a way to have at our disposal the quality in information as required by any firm deserving to be described as adpatable, quick responding, aware of the threats and opportunities of an increasingly internationalized environment, and willing to cater for any present and potential needs of its customers. Come to this point, we would like to to state that another of the purpose of this paper is to show that traditional organizational structures are dissolving and new forms of organizations are emerging. We have tried to outline the organizational changes that the introduction of new information technologies might involve. The main question pointed in our work is wich we might group under the name of +the relationships between nit and organizational structures ;. At this stage, our main hypothesis is + does the growth of nit contribute to the emergence of
Nguyen, Khoa-Van. "Technologie binaurale et contexte de réalité virtuelle : études perceptives et optimisation." Paris 6, 2012. http://www.theses.fr/2012PA066589.
Full textBinaural synthesis is a spatialization technique for headphone listening. It relies on the Head Related Transfer Functions (HRTFs) encoding the auditory space in a unique way for each individual and allows to virtually position an auditory source at any location in space. Binaural synthesis was developed and tested only considering the auditory perception. In this thesis, binaural synthesis is used in the context of virtual reality (VR) environments, involving other sensory modalities. Crossmodal perceptual effects arise and may improve or lower the feeling of presence, which is the aim of RV. We focus on two perceptual and technical aspects about the spatial coherence between the different modalities. First, binaural synthesis is associated with a visual stereoscopic rendering and we run perceptual experiments on visuo-auditory interactions. It is shown that VR gives results that are comparable to those obtained in real conditions. Then, we take advantage of the VR characteristics to use more complexe stimuli and vary the experimental conditions. Second, we explore a method to get a better distance synthesis, especially in near-field, with binaural technique. We use spherical acoustics to extrapolate measured HRTFs toward closer and further distances. This method is compared to other methods and is shown to get slightly better objective results

Full textNiger is a landlocked country in West Africa. Its position on the outskirts of essential poles in the under-region partly explains its delayed development. To this is added, a further delay, called digital divide. Its fleet of obsolete infrastructure does not allow it to take full advantage of global flows of information to take advantage of the competitiveness of the new information society. Spurred on by recent international discussions on new technologies, it appears that the economic development of Niger would require an appropriation of ICTs by the population. Therefore, these new information technologies are at the epicenter of development issues facing the Niger. This research was given the objective to analyze the current system of ICT in Niger and its ability to set off economic development in a context of globalization of economies based on information, knowledge and expertise, by using ICTs. Following this analysis and the questions it poses, some economic theories have emerged, the information economy and its derivatives. In the second time, this study explores, describes, explains, interprets and illustrates these theories in the context of ICTs access. Illustrative examples show that ICT correct some of these predictions. ICT improves human capital, refine agents' anticipations and reduce the risk of economic decisions. That’s why, ICTs can be considered as an economic development factor in Niger. In this revolution of new technologies, the economies have not necessarily need to go through the stage of industrialization as the old theories. The example of China and the Asian dragons shows that

Full textThe sense of professional telematics goes beyond the material technology to englobe a multi-faceted reality, a "concept" in the marketing sense of the word. France telecom who has the main responsability for offering this service (in the form of videotex and teletel) makes use of the concept both in its discourse and its strategy. Neither the technical determinism nor the social determinism explain this construction. The method adapted consists in finding in a genealogical perspective, the manner in which the discourse employed by france telecom incorporates and makes use of certain aspects of social practice while mainteniring its strategy which is to develop minitel into an universal toal. This evolution, far from being linear, consists of reality which can only be defined clearly by placing them in the context : modification of the terminology, hybridization of the technology

Full textHow may we understand the appropriation of the collective intelligence technologies ? We easily believe, about intranets, that sharing and communicating will be quickly adopted and shared practises of enthusiastic users. For who places the orders and who develops these technologies, the collective appropriation poses initially no question. Nevertheless, strong resistances are noticed among the addressees… They give as a pretext they are disfavoured. They argue their practises, their aims and goals, their strategies are not considered. In a word, their situation and how they define it are a far cry from what planned. Uses don’t rise. In our comprehensive research, we will analyse the process of a collective appropriation thanks to three qualitative approaches. One is a systemic approach by modelling the relationship between the actors. The second is an affordancial approach by modelling the actors’ situation. The third is an affordancial approach by modelling the actors website’s consultation. Our research will be enhanced by a case : a community of researchers in nuclear toxicology, Clairatome. Our analyses are aimed to understand the global sense of the website in the situation, its meaning for the researchers of the community, and the adequate uses for part of the actors. The collective appropriation is a long process of redefining the situation that leads to integrated and shared uses. How then can we coach the involvement of each actors ?

Full textIn our search for future uses of information and communication technology, we are inevitably restrained by the limitations of current usage. Artists however when using these technologies may, whether they realize it or not, lead us to certain uses and practices allowing us to imagine some elements of the future. This, of course supposes that artists are capable of anticipating uses in the domain of technical innovation. In order to explore this hypothesis, we decided to analyze artists work to try to understand how " artistic uses " arise during the process of the elaboration and realization of a project, but equally the way in which this work which we qualify as " tekhne-logic " either invent or bring into play new uses (either imagined or real) in contemporary communications. Along with an analysis of multimedia artistic practice, an in depth analysis of the collaboration between France Telecom R-D and artists was conducted over three years (2001 - 2004)

Full textQuantum computing raises a lot of questions related to the foundations of computing. We study, in this thesis, a complexity model called communication complexity, where we study the amount of communication required to solve a distributed task. We study this model from the perspective of quantum information theory. This thesis introduces a new way of obtaining lower bounds on communication complexity, using ideas developed in the study of quantum nonlocality. These methods are compared to previously known lower-bound methods and allow us to define a new family of Bell inequalities. We also prove in this thesis that ail previously known lower bounds for communication complexity are also lower bounds on information complexity. This witnesses the potential equivalence between these two measures of complexity and allows us to obtain direct sum results on the communication complexity of very-well studied functions

Full textInformation and communication technologies have revolutionized work of individuals by their capacity for processing information, and bringing together spaces and time dimensions. During the ten last years, e-mail has been quickly developed in the organizations, certainly by it's facility of use and it's utility. In this context, the main problem is no longer how to access information but its quality and the individual capacity to choose among the various channels of communication the “good” way to work “effectively”. The negative impacts are felt by new practices that are often difficult to predict (information overload, conflicts…). In the light of evolution of 16 theories and models, this research identifies three axes -choice, use and appropriation-, and present meta-analysis in the field of the information systems. Using a statistical analysis of textual French research, the approach allow us to get four different classes: “processing in time”, “HMI”, “productivity compared to the choice of the media” and “use/satisfaction”, under consideration like as a new ways of research, opening lines enquiry. A qualitative study of a multinational in the IT sector has been performed in two distinct phases: documents study and participant observation, semi-structured interviews and analysis of messages. The thesis is completed by managerial prescriptions to be aware of human ans social dimension in processing the information

Full textSince ancient times, Philosophy is a posture sui generis in front of reality, a specific manner of understanding reality: the philosophical attitude is characterized by permanent dissatisfaction regarding to available data. It is this dissatisfaction that turns permanent research, which is designed to find out what is around us, into the most remarkable characteristic of Philosophy.The uncomfortable reasoning, which accompanies the evolution of philosophical thought characterized by permanent searching of ways of dealing with the challenges of the environment in which human beings live, is the main trait of human nature. By examining cultures and information and communication technologies, we believe we are introducing ourselves to one of the really typical human problem, in the sense that we are seeking to find out how we can examine these universal assets of the humanity, but which are, in practice, shaped in the singularity of the people. Moreover, while it is true that the human beings share this characteristic of not enabling the environment to defeat them, but they do whatever they can to dominate it, it is also true that environments are varied and, within this diversity, the human beings test several manners of dealing with different environments. How, then, can this diversity be examined? What role do we attribute to the set of experiences hidden under these life patterns, that is to say, the set of values that do not belong to universal knowledge? With which legitimacy the experiences not hidden should impose themselves upon the universe of cultures?It is within this context that we propose the current analysis, which is based in different acceptations of ICT. As a matter of fact, history demonstrates that human relationships do not always tend to approach different cultures, and that several human deeds were conceived as conditions to justify wars, domination and division among human beings. This fact leads us to a double position: while we keep on regarding ICT as powerful worldwide tools, we start being worried about the fact that ICT are being given a paradigm status in the issue of development, which, as we well demonstrate later, requires other interventions and attentions different from ICT’s.When thinking of the possibility of ICT’s contribution to the issue of development, and when realizing that illiteracy doesn’t enable them to be mastered, we think what has to be done is a reconstitution and reconsideration of peoples’ specific practices, in particular agricultural activities, as a way of dealing with environmental challenges. We are, in this way, back to the issue of technique – conceiving technology as a perfect state of technique – and to the need of attributing a specific role to the technical thought, which enables every human being, in specific conditions, to not just be a simple product of the environment

Full textScientific, technical and medical publishing are subject to the increasing dominance of the industries of mass culture and information. Their power alters the conditions required for publishing to operate in an independent manner and jeopardises its role in scientific communication. Scientific, technical and medical books only play a secondary role as a medium of scientific communication. But, they retain a certain legitimacy in that they are determined by the constraints of scientific endeavour. They are subject to the logic of supply, the logic of science but above all the logic of demand, a mercantile force that tends to prevail. As a result, scientific publishing is less and less an instrument for communicating and promoting science. Publishers are subject to production requirements that are specific to the world of science, which imposes its own standards and endorsement processes. They make only a slight contribution to the organization of publishing as a whole and the control they exercise is increasingly commercial in nature. The acceleration of the industrial process, caused in particular by the development of new technology, does not appear to contribute any additional energy to the sector, which is particularly influenced by the logic of the information industries, proposing increasingly customized services based on upstream control of information flows. The transformation of the sector must also be seen in the context of changes in the world of scientific communication, where technical media and market forces play an increasingly important role

Knowledge, promoter of all these dimensions sustainability, is a capital to be measured and to be bequeathed to the future generations. In this respect, the notions of «informational sustainability» and «paradigm of informational sustainability» have been proposed, emphasizing the participation of information and information and communication technology in the sustainable development. An «information system on the sustainable development» is based on this paradigm and is defined as a complex system centralized and decentralized at the same time, whose feasibility depends on the conditions of the country, such a developing country like Lebanon

Full textThe introduction of information and communication technologies (ICT) in the caring relationship is part of a wider movement, aiming at building a real society of information. Although public health is not spared from those new customs, it nevertheless deserves its own specific study, given the singularity imprinted by patient-doctor relationships. Telemedicine, as a distant medical practice, is characterized by its seniority and the novelty of its normative frame. First of all, offering a spatio-temporal mutation of the medical practice, TIC shift traditional boundaries, including those recognized to the author and finality of the medical act. The doctor-patient bond becomes plural and dematerialized. Then, challenges implied by the resort to TIC, this new technical screen, made very imperious the intervention of the law to supervise and control its use. Caring relationship law resorting to TIC is protean. Doctors and patients' rights and duties invariably apply to this new form of medical practice. However, the lawmaker tried to fill this frame out by initiating dedicated rules, yet remaining piecemeal and lacunar. Resorting to the other fields of law is needed with view to a wide supervision. It however demonstrates its failure or unsuitability for such singular activity

Full textThe office autonation phenomenon has fora long time been limited to a personal and responsive information technology. The purpose of this thesis is to demonstrate to what extempt the computerization of contemporary business management is governed by this primary underlying principle. Our analysis starts from an observation of the sphere of information technology which brings in a number of present restructuring (in the industry, the profession. . . ). The emergence of new actors and the implementation of new strategies - brought about by computer suppliers, users. . . - are taking over rhe role previously played by technicians. This phenomenon is revealing the progressive importance played by the users in the construction of computer technic. Software publishing, as the emergence of communication services or on line information, are based on distincts logics than those computer technicians would have developed. They must be considered as breaking point in the computerization process of business work. These two expressions of the office autamationphenomenon also indicate the present structuration of the information technology market which, by a large diffusion of products and services, create another rationality of computer technic. There is, on a local level inbusiness firms, a reconstitution and a readjustment of the capacities and responsibilities normally assumed by manufacturers (equipment supliers, providers of services) users and technicians. Our questioning is focused on the development of the role and the status of computer scientists in the individualization of practicies in the field of information technology. Observing the aside position of technicians when they face the idea of social construction, we have attempted to deal with questions related to the cultural and ideoliogical fondation of information technology; we think that, in the technician rationality, there are elements which allow one to understand conflicts

Full textNowdays, reducing wireless communication time delay of feedback sensor/actuator system becomes necessary. Our work offers methods, tools and a metrology to assess temporal performances of the Bluetooth links. By developing a specific logarithmic trancoding digital circuit, we fit the use of Bluetooth PCM interface and its synchronous links, initially dedicated to transmitting voice. Thus, the transducer digital data, under strong temporal constraints, can flow through a minimum of protocolar layers ensuring short and limited transmission delay. The original proposed architecture allows to cover a broad variety of communicating transducers. Finally, we propose an extended solution using alternated deterministic frequency hopping where the data are distributed on several transmitters. This scheme affords architectural prospectives of wireless communicating transducers with minimal latency and higher flow

Full textThe media coverage of social relationships by information technology and communication (ICT) to be considered as political technologies is accompanied by an invisibilisation power and a depoliticization of standards. It promotes integration, by the subjects of an order of social practices, and organizes the traceability of human activities. But technology is not the only dimension of social control, whose effectiveness depends on the internalization of the symbolic order of dominant social relationships by the subjects. In organizations, managerial power seeking compliance behavior of employees working their representations, so that they become its relay on themselves, their colleagues and clients. Managerial devices are in the context of an economy of power based on the articulation of control and self¬ control. Think social control must lead to articulate three areas: the symbolic dimension of social relationships (order of discourse and ideology), the instrumental and technological dimension of social relationships (where the symbolic order materializes) and finally the question psychic without which we can not understand how cooperation in processes that they sometimes perceive themselves as alienating is born. Consent, even "voluntary servitude" of someones, as the revolt of some others, results meaning -that is built through mediations- the subjects assign more or less consciously what they live

The latter notion is presently a compulsory passing place for the two cultures. The thesis then centers on the evolution in the pedagogical conceptions of the lecturers in "expression techniques" in the french "polytechnics" (i. U. T. ) since 1969. This evolution points out to a gradual shift from one field of reference to another. The analysis rests on a sorting of the words used by the aforementioned lecturers in the pedagogical journal "expression". The sorting has been carried out with two different methods : the former is subjective and qualitative, the latter quantitative (the words have been counted and sorted thanks to the use of a software specifically modified for carrying out the research). The two methods intersect and confirm the presuppositions : there is an evolution in discourses from a humanistic culture to a technical culture

Full textLe sujet de cette thèse est de discuter les performances et les applications de dispositifs électroniques fabriqués avec des technologies émergentes dans le contexte des systèmes de communication. Après avoir mis en place les systèmes de mesure et les procédures de modélisation qui permettent une analyse systématique de dispositifs électroniques hyperfréquences, nous présentons une étude approfondie de la technologie à base de Nitrure de Gallium (GaN), de la technologie à base de Silicium-Sur-Isolant (SOI), et de la technique d'intégration en trois dimensions de circuits intégrés (3D-MMIC), utilisant le diélectrique InterviaTM8000. Du point de vue des applications, les transistors à effet de champ en GaN concernent le domaine de la haute puissance, du faible bruit, et des hautes températures aux hyperfréquences, et les technologies SOI et 3D-MMIC représentent une alternative ou un complément à la technologie Si-CMOS pour des applications en bande C

Full textInterpersonal and informal resources exchanges among researchers from different organisations are a major source of information for laboratories. Yet, these two-way flows purely depend on individual choices. The goal of this research is to understand the individual decision process, or, why a researcher accepts to exchange certain resources with a certain partner, refuses to exchange other resources with this partner or to exchange these resources with other partners. The research is qualitative and abductive. It aims at the emergence of a grounded theory of the individual decision process. The final model is made of three consecutive steps. The first one differentiates the possible exchange situations in the field of the potential ones. Potential does not always mean possible. It depends on individual factors. The second step discriminates the available resources for the particular partner of the exchange situation. The decision is embedded in the interpersonal relation. The third step leads to the emergence of the exchangeable resources. It depend on the exchange dynamic between partners

Full textUses of the Internet and involvement in school work: ethnographic and quantitative approach of undergraduate degree studentThe influence of Internet practices on student involvement in undergraduate work. This doctoral work looks at a particular aspect of first year students undergraduate experience, notably their level of scholarly involvement within the context of an increasingly prevalent digital world. Some key aspects of the study include documenting student appropriation, relationship to, and use of the Internet (strategies employed) within their academic studies. To examine the relationship between first year students Internet use and their academic studies, this study looked primarily at laptop usage during and outside of class over a period of three to six months. What is innovative about this study is its use of both non-digital and digital data collection methodologies. Non-digital data collection included observation, questionnaire and interviews. Digital data collection, via software, which was installed on students computers, permitted an extremely detailed, account of undergraduate digital practices. The analysis within and between these numerous data collection approaches provided a more in-depth understanding of students digital practices ( the particular use of social media in academic studies) and enabled an examination of the coherency between reported practices and actual practices recorded (the organization of breaks or the continuous use of the Internet during school work). This study shows that the use of the Internet by students is not homogeneous to this population and the impact it can have on studies is more complex than it seems

Full textThe aim of this thesis is to study the impact of information and communication technologies (ICT) on the transaction costs. It is composed of five chapters. The first treated principally the development of « new economy », linked to the democratization of the usage of ICT. These ICT affect also the informational environment of the agents and the nature of their rationality, essential determiners of the transaction costs. The second chapter reminds therefore the reasons of the existence of the theory of transaction costs, as well as its main concepts and hypotheses. The third chapter shows how ICT reduce these transaction costs. We distinguish the impact of ICT on coordination costs and on motivation costs. We demonstrate that ICT reduces coordination costs and increases efficiency. These efficiencies are process improvement of trade and marketplace benefits. At the same time ICT affect motivation costs, we discuss the effect of Internet on informational asymmetries. Our conclusions suggest that reduction of coordination costs is important. However, the Internet is not marked by more asymmetry of information than the traditional market. The fourth chapter is interested in the organizational choice related with the effect of ICT on the transaction costs. The limits of the choice market/hierarchy result in the appearance of the theories which take into account the coexistence of these two organizational choices in new forms of organization such as networks. The main characteristics of these organizational forms make the object of the developments of the last chapter

Full textStudies of verbal interaction in an intercultural situation carried out until now in France have focused on French culture in comparison with other European, Asian, African, Latin-American cultures or Arab groups such as North Africans, Egyptians, Lebanese and Syrians. Other Arab cultures still remain well off this research field. Thus, it appears interesting to undertake a study of intercultural interactions, where the partners are from Yemen and France, whose language of communication is French. The work we present is to analyze, from audiovisual recordings, the difficulties of communication and the means used to overcome them. After explaining the context of the study and the theoretical framework of research, we investigate the communicative and interactional conducts of Yemeni subjects practicing the French language to determine their competence to communicate in an intercultural environment and in exolingual situation, the nature of their gaps as well as their efforts to overcome these difficulties. We identify the communication strategies implemented to repair any dysfunction or misunderstanding. The purpose of our study is, in fact, to contribute to a better knowledge of the intercultural communication by making, using (ICT), didactic proposals to the teaching of French language for Yemeni learners, because awareness of the communicative differences helps to reduce misperceptions and misunderstandings often affecting the intercultural meetings
