Coherence of self-concept refers to the ability to stabilize on a clear set of views about oneself. This aspect of self-structure is closely linked self-esteem, and similar evidence in emotion research suggests an intricate connection between the self-system and emotion. Evidence suggests that emotions of seemingly opposing valence such as happy and sad can co-occur (i.e., mixed emotion). This study validated a new set of emotional stimuli particularly to elicit mixed emotion and used these stimuli with a mouse task that allowed participants to report positive and negative emotions simultaneously. The study examined possible individual differences in discrete emotional response associated with self-esteem as well as a possible connection between selfconcept coherence and a differential ability to harbor mixed emotions; specifically that individuals with high coherence in self-concept would tend to disambiguate their emotional response, but those with low coherence would be more susceptible to cooccurring positive and negative emotion. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

Iterative Learning Control (ILC) iterates with a real world control system repeatedly performing the same task. It adjusts the control action based on error history from the previous iteration, aiming to converge to zero tracking error. ILC has been widely used in various applications due to its high precision in trajectory tracking, e.g. semiconductor manufacturing sensors that repeatedly perform scanning maneuvers. Designing effective feedback controllers for non-minimum phase (NMP) systems can be challenging. Applying Iterative Learning Control (ILC) to NMP systems is particularly problematic. Asking for zero error at sample times usually involves inverting the control system. However, the inverse process is unstable when the system has NMP zeros. The control action will grow exponentially every time step, and the error between time steps also grows exponentially. If there are NMP zeros on the negative real axis, the control action will alternate its sign every time step. ILC must be digital to use previous run data to improve the tracking error in the current run. There are two kinds of NMP digital systems, ones having intrinsic NMP zeros as images of continuous time NMP zeros, and NMP sampling zeros introduced by discretization. Two ILC design methods have been investigated in this thesis to handle NMP sampling zeros, producing zero tracking error at addressed sample times: (1) One can simply start asking for zero error after a few initial time steps, like using multiple zero order holds for the first addressed time step only (2) Or increase the sample rate, ask for zero error at the original rate, making two or more zero order holds per addressed time step. The internal instability can be manifested by the singular value decomposition of the input-output matrix. Non-minimum phase systems have particularly small singular values which are related to the NMP zeros. The aim is to eliminate these anomalous singular values. However, when applying the second approach, there are cases that the original anomalous singular values are gone, but some new anomalous singular values appear in the system matrix that cause difficulties to the inverse problem. Not asking for zero error for a small number of initial addressed time steps is shown to eliminate all anomalous singular values. This suggests that a more accurate statement of the second approach is: using multiple zero order holds per addressed time step, and eliminating a few initial addressed time steps if there are new anomalous singular values. We also extend the use of these methods to systems having intrinsic NMP zeros. By modifying ILC laws to perform pole-zero cancellation inside the unit circle, we observe that all of the rules for sampling zeros are effective for intrinsic zeros. Hence, one can now achieve convergence to zero tracking error at addressed time steps in ILC of NMP systems with a well behaved control action. In addition, this thesis studies the robustness of the two approaches along with several other candidate approaches with respect to model parameter uncertainty. Three classes of ILC laws are used. Both approaches show great robustness. Quadratic cost ILC is seen to have substantially better robustness to parameter uncertainty than the other laws.

University of Technology, Sydney. Faculty of Business. / The need for more dynamic views on international joint ventures' control research has recently become a growing concern. Changes in the complexity of relationships between organisations and their environments have led to an increase in control problems and to a need to investigate a suitable framework of management control. The concept of self-organising systems that has emerged with the science of complexity produces some useful and interesting new ways to examine the behaviour of complex systems. Therefore, extending the recent development in self-organising systems into international joint ventures' control research is an opportunity to explore new insights into the development of joint ventures. This study takes an integrative approach by focusing on the integration of management control and self-organising properties of international joint ventures. The purpose of this study is to investigate the roles of management control systems in affecting international joint ventures' performance, from the perspective of alliance complexity constraints. A model of management control in international joint ventures as self-organising systems, representing a complexity-control-outcomes framework, is developed and tested empirically using the partial least square (FLS) approach, a distinctive structural equation modeling (SEM) based technique. The primary results of this study show that formal control mechanisms and control extent have significant direct effects on management automony and the international joint ventures' performance. Management autonomy as an intervening endogenous construct has a significant direct effect on the international joint ventures performance. Significant direct effects of organisational complexity on the formal control mechanisms and control extent are found, and a significant indirect effect of organisational complexity on the management autonomy is found. The overall results suggest a sound link between the complexity-control framework with the control-outcome framework, and the achievement of fit between these two frameworks is important for superior international joint ventures' performance.

<p>This dissertation is a study of the development of a video game called Anarchy Online. This game was developed by the Funcom company between 1995 and 2001, and is a so-called Massively Multiplayer Online Role-Playing Game (MMORPG). This genre of video games differs from traditional games in that it offers a persistent virtual world that gamers can access at all hours of the night or day. It is also a world where gamers make avatars that play with or against each other. All in all, it is as much a social sphere as a game. The popularity of MMORGPGs has continued to increase, and today there are several million gamers worldwide who participate in these virtual worlds. Because virtual worlds are places where many people socialize, play, and spend a great deal of time, there is a need to form an understanding of them. In this thesis, I am studying how Anarchy Online was produced in order to understand the assumptions behind the rules governing the interaction in this specific virtual world were selected and organized. In doing so, I am using material from two sources: the developers and the game itself. This material was gathered through interviews, documents, and virtual ethnographic observations.</p><p>Ultimately, games consist of codes; but in order to program the code, they need to be specified by a game content. The analysis shows that the content of the game is defined by the developers’ view of a good society – the belief in a human being’s need for self-actualization and social interaction. The thesis thus concludes with the observation that the need to select the discourses and/or philosophies for content and possible gamers’ actions requires the development of games and virtual worlds such as Anarchy Online to be more than the creation of an entertaining product. Rather, discourses were recreated from the physical world in which the developers live. In the end, gamers are locked into a discoursive prison created by the developers.</p>

Small failures should only disrupt a small part of a network. One way to do this is by marking the surrounding area as untrustworthy --- circumscribing the failure. This can be done with a distributed algorithm using hierarchical clustering and neighbor relations, and the resulting circumscription is near-optimal for convex failures.
