Organisational culture and coach-athlete relationships : an ethnographic study of an elite rowing club

Maitland, Alison January 2012 (has links)
This thesis explores how coach-athlete relationships are influenced within the organisational culture of a rowing club. Relational Cultural Theory and the work of Weber are used to examine how the concept of organisational culture informs understanding of coach and athlete relating. The study, covering a complete competitive season, involved an eleven month long ethnography of an elite rowing club in Great Britain. The findings demonstrate the visceral, enculturated and complex nature of coach-athlete relationships in elite sport. Relational disconnection occurred in the disenchanted organisational life, where intrinsic values were subordinated to a rational quest for efficiency, control and ultimately success, as well as traditional social ordering based on status and gender. Relationships were characterised by power over relating, distance and impersonal relations, caretaking rather than caring about, fragile trust by the athlete and trust through surveillance by the coach, where emotion was concealed and conflict avoided. However, enacting shared identities, the emotion involved in competing and the fact this was a voluntary organisation with competing values, provided an escape from simulacra of elite sport to allow for multi-value paradigm of interests. The opportunity for coaches and athletes to connect with each other based on their values and with emotion exposed their humanity and revealed the potential for relational mutuality and authenticity. The study challenges the valorised coaching and elite sport relationships and lifestyle. Implications for coaching include providing individuals with confidence to raise the issue of relationship, providing coaches and athletes with knowledge of connection and disconnection in relationship and the outcome on well-being. The need to develop a systemised approach to embedding growth-fostering relationships in the culture of high performance sport is highlighted.

Compositional synthesis via convex optimization of assume-guarantee contracts

Ghasemi, Kasra 17 January 2023 (has links)
Ensuring constraint satisfaction in large-scale systems with hard constraints is vital in many safety critical systems. The challenge is to design controllers that are efficiently synthesized offline, easily implementable online, and provide formal correctness guarantees. We take a divide and conquer approach to design controllers for reachability and infinite-time/finite-time constraint satisfaction control problems given large-scale interconnected linear systems with polyhedral constraints on states, controls, and disturbances. Such systems are made of small subsystems with coupled dynamics. Our goals are to design controllers that are i) fully compositional and ii) decentralized, such that online implementation requires only local state information. We treat the couplings among the subsystems as additional disturbances and use assume-guarantee (AG) contracts to characterize these disturbance sets. For each subsystem, we design and implement a robust controller locally, subject to its own constraints and contracts. Our main contribution is a method to derive the contracts via a novel parameterization, and a corresponding potential function that characterizes the distance to the correct composition of controllers and contracts, where all contracts are held. We show that the potential function is convex in the contract parameters. This enables the subsystems to negotiate the contracts with the gradient information from the dual of their local synthesis optimization problems in a distributed way, facilitating compositional control synthesis that scales to large systems. We then incorporate Signal Temporal Logic (STL) specifications into our formulation. We develop a decentralized control method for a network of perturbed linear systems with dynamical couplings subject to STL specifications. We first transform the STL requirements into set containment problems, then we develop controllers to solve these problems. The set containment requirements and parameterized contracts are added to the subsystems’ constraints. We introduce a centralized optimization problem to derive the contracts, reachability tubes, and decentralized closed-loop control laws. We show that, when the STL formula is separable with respect to the subsystems, the centralized optimization problem can be solved in a distributed way, which scales to large systems. We present formal theoretical guarantees on robustness of STL satisfaction. We present numerical examples, including scalability studies on systems with tens of thousands of dimensions, and case studies on applying our method to a distributed Model Predictive Control (MPC) problem in a power system. / 2024-01-16T00:00:00Z

The Development of a Reliable Change Index and Cutoff for the SCORE-15

Nebeker Adams, Cara Ann 01 December 2018 (has links)
The Systemic Clinical Outcome and Routine Evaluation version 15 (SCORE-15) is an assessment used to assess for clinical change in family functioning. The SCORE-15 has been demonstrated in the past to be a reliable and valid measure for assessing for clinical change and is largely used throughout the UK. However, the SCORE-15 lacks the ability to determine whether an individual's change in family functioning is clinically significant. This study aims to establish a reliable change index and clinical cutoff score based on a US sample so that researchers and clinicians can determine clinically significant change. A sample of 63 clinical participants and 244 community participants completed the SCORE-15, including 165 community participants who completed the SCORE-15 a second time. Results established a cutoff of 51.92 and a reliable change index of 17.51 for the SCORE-15. This indicates that therapy clients who improve their SCORE-15 score by at least 17.5 points and who cross the threshold of 52 during the course of therapy are considered to have experienced clinical significant improvement.

Greek Foreign Policy : The Case Study of Greco-Turkish Relations under the two consecutive Kostas Simitis Premierships (1996-2000) and (2000-2004)

Guzer, Osman Cenk January 2005 (has links)
<p>The relations between Greece and Turkey have developed at an unprecedented level in recent years. Behind this development lay certain factors notably the Simitis Governments’ strategy of redefining the parameters of Greek national interests in foreign policy and the Turkish Governments’ subsequent positive responses to this favorable atmosphere. It is thus possible to use the term ‘détente’ to refer to the period which dates back to 1996, the rise of Simitis to the Greek premiership. Some observers on Greco-Turkish Relations tend to trace the origins of Greco-Turkish détente to the devastating 17 August earthquake in Turkey. Some others try to find the origin of détente in the 1999 Helsinki Summit where Turkey was offered the candidacy status for the EU membership. This thesis proposes an alternative approach by defending the view that the rise of Simitis to the prime ministry itself heralded the chain of events which would later pave the road to the relaxation of Greco-Turkish Relations.</p><p>This thesis is a modest attempt to understand the anatomy of Simitis Leadership and its reflections on Greco-Turkish Relations. On the basis of certain turning points in a chronological fashion, it will uncover the background of an eight-year ruling term with its ups and downs. There is an irony in Greco-Turkish Relations: Outbreak of crises between the two neighbors led both the Greek and the Turkish political actors to re-examine their attitude in the following phase of their relationship. In the Simitis Era, the tensions created opportunities for building up networks of cooperation initiatives to a certain extent. I also argue here that spillover logic in Greco-Turkish Relations has started working- albeit cautiously- and that this spirit could be sustainable if managed by both sides wisely. Continuation of the Greco-Turkish détente even after the governmental change in Athens in April 2004 demonstrates that the Simitis Leadership has determined a new framework for Greco- Turkish Relations. This framework has been set through pushing Turkey to the future EU membership orientation and setting mechanisms of reward/punishment (or carrot/stick) policy on Turkey’s route to Brussels through the EU.</p>

Religious Commitment, Religious Harm, and Psychological Distress: Course of Treatment Outcomes

Abegg, Dane 14 August 2023 (has links) (PDF)
This study examines the intersection of religion, mental health, and psychotherapy, specifically focusing on the concept of religious injury or harm. The literature review reveals a gap in research regarding the identification of religion as a potential source of emotional pain in religious individuals. To address this gap, this longitudinal study utilized intake data from 1303 clients and follow-up data from 748 clients three months after the completion of psychotherapy treatment. Primary objectives of the study were to examine whether religious commitment changes over the course of psychotherapy, explore if religious commitment influences mental health counseling outcomes, and better understand the relationship between psychological distress, religious commitment, and therapy outcomes among individuals who perceive religion as having harmed them. The results demonstrate that regardless of religious injury status, psychological distress decreased throughout the treatment period. Furthermore, psychotherapy not only reduced psychological distress but also altered client's religious commitment. Higher religious commitment at follow-up appeared to mitigate the negative effects of religious harm on therapy outcomes, resulting in lower levels of religious harm and improved therapy outcomes. These findings suggest that psychotherapy can effectively alleviate psychological distress and modify religious commitment for individuals who perceive religion as harmful. This research contributes to the existing literature on psychology and religion and emphasizes the need for further exploration of the complex relationship between religion, mental health, and therapeutic interventions.

Military housing privatization initiative lessons learned program : an analysis

Elbert, Janet M. 09 1900 (has links)
Approved for public release; distribution in unlimited. / The Military Housing Privatization Initiative (MHPI) represents a dramatic revision in the construction and maintenance of military housing. Since its inception in 1996, the number of projects has grown exponentially and the learning process has been continuous and steep. This thesis researches the effectiveness of the methods in place at the Department of Defense and Service levels to document, share, and, above all, learn from past experiences. This analysis reviews the cumulative documented lessons from all Services and compares it to the lessons learned within the first jointly partnered privatization project at the Presidio of Monterey (POM) and Naval Postgraduate School (NPS) in Monterey, California. This research showed at least six lessons previously documented within the lessons learned system, which were relearned at the POM/NPS project. Given this data, the lessons learned program is a partial success but overall has a positive impact on the MHPI. The current lessons learned program improves each new privatization project ensuring it does not experience all of the same lessons from previous projects. Only a few lessons seem to slip through the cracks and are repeated even after documentation and distribution. / Captain, United States Army

Struktura a dynamika těsných interpersonálních vztahů / Structure and dynamics of close personal relationships

Horáková Hurychová, Zuzana January 2014 (has links)
Zuzana Horáková Hurychová Dissertation: Structure and dynamics of close personal relationships ABSTRACT Keywords: Close personal relationship, components of close relationships, close relationship's dynamics, relationship type, methods of measuring close relationships, prototype approach, RCI, DOTEV The thesis deals with close personal relationships and their specific characteristics. Even though this area has been extensively explored abroad, it has received little attention in the Czech Republic. We can see a certain paradox: While there are no standard methods of measuring or specifying relationship characteristics of the Czech population, foreign literature is abundant in theories on how close personal relationships work, offering methods of their measurement. These methods usually focus on a specific component of the relationship. Therefore, it has not been possible to fully meet the objectives of this thesis. The first objective was to perform a theoretical mapping of close relationships, which is not fully possible due to the limited extent of the thesis. Thus, I only focused on the most frequently cited and most interesting, in my opinion, concepts that offer practical methods of measuring close relationships. The thesis offers a wide, though not exhaustive, overview that has served as a basis for...
