La fabrication du leader et du leadership : analyse des processus de transformation dans trois grandes organisations / The making of a leader and of leadership : the analysis of the transformation processes inside three large organizationsMorin, Gabriel 03 December 2016 (has links)
La recherche porte sur l’analyse de la fabrication du leader et du leadership et vise à comprendre les étapes organisationnelles permettant de développer ce processus. Leader et leadership ont été abondamment traités en sciences de gestion. L’avènement d’un nouvel environnement, obligeant les organisations à se transformer, en a fait un enjeu stratégique. Celui-ci a conduit à l’émergence d’un nouveau paradigme depuis 2000. Ce nouveau courant s’appuie sur un renouvellement des études empiriques, une approche plus ouverte et des disciplines variées (psychologie, mathématiques et neurosciences). Ses apports structurent les études autour de deux axes clés : la distinction entre leader et leadership et la capacité d’une organisation à fabriquer ces attributs chez l’individu. Notre recherche s’inscrit dans ce paradigme avec une idée force : ce type de fabrication passe par des processus de transformation, notamment identitaires, qu’il convient, pour les entreprises, d’explorer davantage et de manière plus dynamique. Le dispositif mis en place établit une grille d’analyse mobilisant différents courants de recherche afin d’améliorer la compréhension de la fabrication du leader et du leadership. Ce cadre souligne les effets produits par, et sur, trois principaux champs contextuels : individu (Hughes), organisation (Giddens) et environnement (Emery et Trist). Il fait l’objet d’une transposition originale en sciences de gestion qui souligne la plasticité identitaire individuelle et la récursivité du phénomène étudié. L’analyse empirique s’appuie sur une étude de cas multiple de trois grandes organisations qui partagent une pratique managériale volontariste de développement du leader et du leadership, dont l’institution militaire, berceau de ces notions. Les conclusions soulignent l’existence d’un processus de co-création du leader et du leadership, fruit d’interactions entre environnement, organisation et individu. Ces flux transformatifs vivants répondent à ce qui est théorisé comme un agencement inter-contextuel et conduit à des préconisations managériales structurant la fabrication du leader et du leadership. / The research focuses on the analysis of the making of a leader and of leadership and aims at understanding the steps that allow large organizations to develop this process.Leader and leadership have been extensively discussed in management sciences. With the rise of a new environment requiring organizations to transform themselves, these notions have become a strategic challenge. This challenge has led to the emergence of a new paradigm of leadership in management sciences since the 2000s. This new stream, particularly embodied by the work of David Day (2000), is based on a renewal of empirical studies and on an approach more open to various disciplines such as psychology, mathematics and neuroscience. That current has contributed to the structuring of the field of studies on leader and leadership. Research increasingly focuses on the essential distinction between leader and leadership and on the organizations’ role in the making of these attributes within the individual. Our research fits into this paradigm by adding one idea: this type of making involves multiple transformation processes, including identity dimensions, which companies ought to explore more actively.The purpose of the research design is to establish an analytical framework that mobilizes different streams of research in order to help understand the making of a leader and of leadership. This framework will highlight the effects of, and on, three main contextual fields: the individual (Hughes), the organization (Giddens)and the environment (Emery and Trist). This is the subject of an original transposition in management sciences which puts the emphasis on the individual identity plasticity (Hughes) and recursivity of the phenomenon. The empirical analysis will be based on the multiple case study of three major organizations that share a proactive management of leader and leadership development, including the Army, the birthplace of such notions. The findings point out the existence of a process of co-creation of a leader and leadership, which is the result of interactions between the environment, the organization and the individual. These transformative live flows are theorised as an inter-context assemblage. This will lead to managerial recommendations for enabling the making of a leader and the leadership.

How Often do Experts Make Mistakes?Palix, Nicolas, Lawall, Julia L., Thomas, Gaël, Muller, Gilles January 2010 (has links)
Large open-source software projects involve developers with a wide variety of backgrounds and expertise. Such software projects furthermore include many internal APIs that developers must understand and use properly. According to the intended purpose of these APIs, they are more or less frequently used, and used by developers with more or less expertise. In this paper, we study the impact of usage patterns and developer expertise on the rate of defects occurring in the use of internal APIs. For this preliminary study, we focus on memory management APIs in the Linux kernel, as the use of these has been shown to be highly error prone in previous work. We study defect rates and developer expertise, to consider e.g., whether widely used APIs are more defect prone because they are used by less experienced developers, or whether defects in widely used APIs are more likely to be fixed.

Malleability, obliviousness and aspects for broadcast service attachmentHarrison, William January 2010 (has links)
An important characteristic of Service-Oriented Architectures is that clients do not depend on the service implementation's internal assignment of methods to objects. It is perhaps the most important technical characteristic that differentiates them from more common object-oriented solutions. This characteristic makes clients and services malleable, allowing them to be rearranged at run-time as circumstances change. That improvement in malleability is impaired by requiring clients to direct service requests to particular services. Ideally, the clients are totally oblivious to the service structure, as they are to aspect structure in aspect-oriented software. Removing knowledge of a method implementation's location, whether in object or service, requires re-defining the boundary line between programming language and middleware, making clearer specification of dependence on protocols, and bringing the transaction-like concept of failure scopes into language semantics as well. This paper explores consequences and advantages of a transition from object-request brokering to service-request brokering, including the potential to improve our ability to write more parallel software.

AspectKE*: Security aspects with program analysis for distributed systemsFan, Yang, Masuhara, Hidehiko, Aotani, Tomoyuki, Nielson, Flemming, Nielson, Hanne Riis January 2010 (has links)
Enforcing security policies to distributed systems is difficult, in particular, when a system contains untrusted components. We designed AspectKE*, a distributed AOP language based on a tuple space, to tackle this issue. In AspectKE*, aspects can enforce access control policies that depend on future behavior of running processes. One of the key language features is the predicates and functions that extract results of static program analysis, which are useful for defining security aspects that have to know about future behavior of a program. AspectKE* also provides a novel variable binding mechanism for pointcuts, so that pointcuts can uniformly specify join points based on both static and dynamic information about the program. Our implementation strategy performs fundamental static analysis at load-time, so as to retain runtime overheads minimal. We implemented a compiler for AspectKE*, and demonstrate usefulness of AspectKE* through a security aspect for a distributed chat system.

"Minds will grow perplexed": The Labyrinthine Short Fiction of Steven MillhauserAndrews, Chad Michael 25 February 2014 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Steven Millhauser has been recognized for his abilities as both a novelist and a writer of short fiction. Yet, he has evaded definitive categorization because his fiction does not fit into any one category. Millhauser’s fiction has defied clean categorization specifically because of his regular oscillation between the modes of realism and fantasy. Much of Millhauser’s short fiction contains images of labyrinths: wandering narratives that appear to split off or come to a dead end, massive structures of branching, winding paths and complex mysteries that are as deep and impenetrable as the labyrinth itself. This project aims to specifically explore the presence of labyrinthine elements throughout Steven Millhauser’s short fiction.
Millhauser’s labyrinths are either described spatially and/or suggested in his narrative form; they are, in other words, spatial and/or discursive. Millhauser’s spatial labyrinths (which I refer to as ‘architecture’ stories) involve the lengthy description of some immense or underground structure. The structures are fantastic in their size and often seem infinite in scale. These labyrinths are quite literal. Millhauser’s discursive labyrinths demonstrate the labyrinthine primarily through a forking, branching and repetitive narrative form.
Millhauser’s use of the labyrinth is at once the same and different than preceding generations of short fiction. Postmodern short fiction in the 1960’s and 70’s used labyrinthine elements to draw the reader’s attention to the story’s textuality. Millhauser, too, writes in the experimental/fantastic mode, but to different ends. The devices of metafiction and realism are employed in his short fiction as agents of investigating and expressing two competing visions of reality. Using the ‘tricks’ and techniques of postmodern metafiction in tandem with realistic detail, Steven Millhauser’s labyrinthine fiction adjusts and reapplies the experimental short story to new ends: real-world applications and thematic expression.

Evaluation of Target Tracking Using Multiple Sensors and Non-Causal AlgorithmsVestin, Albin, Strandberg, Gustav January 2019 (has links)
Today, the main research field for the automotive industry is to find solutions for active safety. In order to perceive the surrounding environment, tracking nearby traffic objects plays an important role. Validation of the tracking performance is often done in staged traffic scenarios, where additional sensors, mounted on the vehicles, are used to obtain their true positions and velocities. The difficulty of evaluating the tracking performance complicates its development. An alternative approach studied in this thesis, is to record sequences and use non-causal algorithms, such as smoothing, instead of filtering to estimate the true target states. With this method, validation data for online, causal, target tracking algorithms can be obtained for all traffic scenarios without the need of extra sensors. We investigate how non-causal algorithms affects the target tracking performance using multiple sensors and dynamic models of different complexity. This is done to evaluate real-time methods against estimates obtained from non-causal filtering. Two different measurement units, a monocular camera and a LIDAR sensor, and two dynamic models are evaluated and compared using both causal and non-causal methods. The system is tested in two single object scenarios where ground truth is available and in three multi object scenarios without ground truth. Results from the two single object scenarios shows that tracking using only a monocular camera performs poorly since it is unable to measure the distance to objects. Here, a complementary LIDAR sensor improves the tracking performance significantly. The dynamic models are shown to have a small impact on the tracking performance, while the non-causal application gives a distinct improvement when tracking objects at large distances. Since the sequence can be reversed, the non-causal estimates are propagated from more certain states when the target is closer to the ego vehicle. For multiple object tracking, we find that correct associations between measurements and tracks are crucial for improving the tracking performance with non-causal algorithms.
