How Yoga Masters Experience Mindfulness

January 2012 (has links)
abstract: This study addressed the questions: What is the experience of mindfulness by yoga masters? How can such experiences inform the counseling intervention of mindfulness? In a qualitative study, individuals who held the minimum credentials E-RYT 200 (i.e., Experienced Registered Yoga Teacher 200 Hour) were interviewed. The verbatim interviews were analyzed using the phenomenological approach. Two categories of themes emerged describing mindfulness as a state of being and a practice of awareness. The common themes describing mindfulness as a state of being include: conscious awareness, feeling bliss, the present moment, interconnectedness, and compassionate evolution. The common themes describing mindfulness as a practice of awareness include: waking the body, balanced practice, the power of pranayama, refining abilities, obstacles to awareness, a holistic practice, and external supports. The results of this study suggest that mindfulness is multifaceted and ephemeral; however, with regular practice it becomes more consistently maintained. As a practice of awareness, mindfulness develops through a hierarchy of techniques moving from the external to the internal including both self and other. Discussion focuses on how these experiences can be applied in counseling interventions. / Dissertation/Thesis / M.C. Counseling 2012

How Discourses Cast Airport Security Characters: A Discourse Tracing and Qualitative Analysis of Identity and Emotional Performances

January 2013 (has links)
abstract: Since the September 11, 2001 terrorist attacks and subsequent creation of the Transportation Security Administration (TSA), airport security has become an increasingly invasive, cumbersome, and expensive process. Fraught with tension and discomfort, "airport security" is a dirty phrase in the popular imagination, synonymous with long lines, unimpressive employees, and indignity. In fact, the TSA and its employees have featured as topic and punch line of news and popular culture stories. This image complicates the TSA's mission to ensure the nation's air travel safety and the ways that its officers interact with passengers. Every day, nearly two million people fly domestically in the United States. Each passenger must interact with many of the approximately 50,000 agents in airports. How employees and travelers make sense of interactions in airport security contexts can have significant implications for individual wellbeing, personal and professional relationships, and organizational policies and practices. Furthermore, the meaning making of travelers and employees is complexly connected to broad social discourses and issues of identity. In this study, I focus on the communication implications of identity and emotional performances in airport security in light of discourses at macro, meso, and micro levels. Using discourse tracing (LeGreco & Tracy, 2009), I construct the historical and discursive landscape of airport security, and via participant observation and various types of interviews, demonstrate how officers and passengers develop and perform identity, and the resulting interactional consequences. My analysis suggests that passengers and Transportation Security Officers (TSOs) perform three main types of identities in airport security contexts--what I call Stereotypical, Ideal, and Mindful--which reflect different types and levels of discourse. Identity performances are intricately related to emotional processes and occur dynamically, in relation to the identity and emotional performances of others. Theoretical implications direct attention to the ways that identity and emotional performances structure interactions, cause burdensome emotion management, and present organizational actors with tension, contradiction, and paradox to manage. Practical implications suggest consideration of passenger and TSO emotional wellbeing, policy framing, passenger agency, and preferred identities. Methodologically, this dissertation offers insight into discourse tracing and challenges of embodied "undercover" research in public spaces. / Dissertation/Thesis / Ph.D. Communication Studies 2013

When the Watchers Become the Watched: A Qualitative Inquiry into Police Officer Perceptions of Body-Worn Cameras

Aksin, Nevena 23 April 2018 (has links)
Recently, police legitimacy has come under attack due to ongoing allegations of police use of excessive force. In line with national efforts to modernize police services, body-worn cameras have been positioned as a promising response to reconstructing police legitimacy due to their potential to provide greater transparency and accountability (Brucato, 2015). Despite the rapid and extensive adoption of body-worn cameras by North American police services (Brucato, 2015), there is a great deal of uncertainty regarding effective policy, implementation and expected outcomes. As it stands, the current research that examines the impact of body-worn cameras on citizen complaints and police use of force presents a narrow understanding of their use. Existing research calls for future studies to examine officer perceptions of body-worn cameras in order to gain a more comprehensive understanding of their value and impact (Boyd, Mateescu & Rosenblat, 2015). As such, the primary research objective of this study is to understand how police officers perceive the use of body-worn cameras. Semi-structured interviews were conducted with police officers from the Toronto Police Service. By drawing on Orlikowski and Gash’s (1994) technological frames of reference framework, the study concludes that officers felt that both of the BWC models during the pilot project were inadequate, were skeptical about the potential of BWCs due to the belief that BWCs are a tool primarily used to “keep an eye on the police”, believed that BWCs impact officer and citizen conduct in ways that can potentially harm police-community relationships, and reported using BWCs to gain greater control over police visibility. Recommendations for training and body-worn camera program development are presented at the end of the study, along with directions for future research.

Devenir NEET (Not in Education, Employment or Training) : une étude sur les jeunes ni en emploi, ni en formation de l'arrondissement de Lille / Become NEET ( Not in Edication, Employment or Training) : a study on NEET in the borough of Lille

Kadimpeul, Dieudonné 27 September 2016 (has links)
Cette thèse analyse le comportement sur le marché du travail local de185 jeunes peu ou pas qualifiés âgés de 16 à 29 ans de l’arrondissement de Lille. Elle met en lumière les difficultés d’insertion professionnelle qu’ils rencontrent eu égard à l’absence ou un faible niveau de diplôme, de qualification, d’expérience professionnelle. Aussi met-elle en exergue leurs méconnaissances des réalités du marché du travail local à travers leurs prétentions salariales, leurs techniques de recherche d’emploi, leurs projets ; et leurs stratégies pour rester ou se maintenir hors de ce marché. La démarche qualitative a permis une vérification empirique des facteurs répertoriés par l’Eurofound qui ont un impact sur le risque de devenir NEET (not in education, employment or training : les jeunes qui ne sont ni scolarisés, ni en emploi, ni en formation). Une typologie de trajectoires qui conduisent à être NEET dans l’arrondissement de Lille est établie. L’hétérogénéité caractérise la catégorie de NEET. Cette disparité relève d’abord des sous-groupes qui existent au sein des NEET. Aussi, se matérialise-t-elle suivant les systèmes éducatifs, les politiques sociales, les réalités socioéconomiques et culturelles qui sont spécifiques aux territoires (départements, régions, pays). La connaissance de la catégorie des NEET via sa construction sociale dans l’arrondissement de Lille va permettre aux différents acteurs locaux (région, départements, associations, etc.) d’avoir une visibilité claire sur les stratégies à adopter et/ou les politiques à mettre en œuvre pour l’inclusion sociale de ces derniers. / This thesis analyzes the behavior of the local labor market of 185 young people low-skilled aged 16 to 29 years of the district of Lille. It puts in light of the difficulties they encounter employability given the absence (or low levels) of qualification, qualification, professional experience. She also puts highlight their misconceptions of the local labor market realities through their salary expectations, their job search techniques, their projects; and strategies to stay or keep out of the market. The qualitative approach enabled an empirical verification of the factors listed by Eurofound which impact on the risk of becoming NEET (Not in Education, Employment or Training: young people who are neither in education nor in employment or training). A typology of trajectories that lead to be NEET in the district of Lille is established. The heterogeneity characterizes the NEET category. This disparity is primarily a matter of subgroups that exist within the NEET. Also, according to context, it materializes educational systems, social policies, socio-economic and cultural realities which are specific territories (departments, regions, countries). Knowing the NEET category via its social construction in the district of Lille will allow different local actors (region, departments, associations, etc.) to have a clear visibility on the strategies to adopt and/or policies implement for social inclusion of the latter.

What can a CAQDAS analysis reveal about university textual identity?

Dickinson, Mary J. January 2002 (has links)
This thesis argues that changes in the 'idea' of the university can be identified through an analysis of the textual identities of institutions utilising Computer Assisted Qualitative Data Analysis Software (CAQDAS). The historical review at the beginning of the work identifies four key, perennial aspects of university identity and function: (i) transmitting knowledge and producing cultured students; (ii) research; (iii) training for employment; and (iv) a wider duty to society. The thesis rests upon the premise that the relative prominence of each of these four aspects in university publications gives a university a certain textual identity at a given time. The thesis further suggests that certain specific forces - State intervention, economic pressures, industry, and competition - affect the priority given to these aspects. The University of Surrey is examined as a case study and changes in the relative prominence of these aspects are observed in the textual presentation of this institution over time. These findings, when compared with an analysis of the public documents of a cross-sector sample of other institutions, revealed different textual identities and this has implications regarding university mission and performance. The thesis shows that external factors do have an influence upon textual identity. CAQDAS was also able to reveal that university textual identity is not monolithic and varies over time and depending on the intended audience. The remit of the study extends to January 2002, and is therefore timely in light of the 2001 review of the structure and funding of higher education (Newby, 2001), particularly because a key aspect of the Newby review is the increasingly explicit linking of funding to mission. This analysis contributes to debates in higher education concerning institutional identity, the usefulness of existing institutional typologies, mission, and possible futures for the sector. The study also makes a methodological contribution to educational research in its innovative employment of the CAQDAS tool.

The Use of Technology in Nursing: A Grounded Theory for Getting a Picture

Nagel, Daniel January 2017 (has links)
Background: Using technology requires nurses to capture, retrieve and organize digital data within virtual environments. Nurses often integrate digital data with other data sources when providing patient care with telehealth technologies and conducting research. Little is understood of how nurses navigate technology and process digital data in professional practice. Purpose: The overall aim of this dissertation was to explore how nurses navigate virtual environments and integrate digital data in professional practice through a grounded theory study of how nurses know the person using telehealth technology. The goals of the dissertation were to: a) Describe how knowing the person occurs with use of telehealth technology; b) Create a theoretical conceptualization of how the nurse comes to know the person in a virtual environment; and, c) Explicate data collection and analytical processes in Charmaz’s constructivist grounded theory. Methods Charmaz’s constructivist grounded theory (ConGT) was used for the research study. Findings: The process of conducting this study yielded two outcomes: 1. A grounded theory and conceptualization for Getting a Picture, which illuminates an integrated and iterative interplay of seven processes and 21 sub-processes that nurses described when forming a mental image of the person being cared for. Twenty-two registered nurses from five telehealth programs in two different provincial health systems participated. Primary data sources included 22 first interviews and 11 second interviews with the participants, and five observational experiences. 2. The approach for conducting ConGT involved operationalizing a series of five steps in the analytic process to visualize and conceptualize Getting a Picture. These steps included Initial Data Collection, Initial Coding, Focused Coding, Theoretical Coding and Theory Building. Conclusion: Visualization played an instrumental role when technology was used for both knowing the person in a virtual environment and operationalizing the methodological processes for this ConGT research study. Three main themes related to this overall finding in this dissertation were: (a) visualization and conceptualization to create a mental image is evident in both clinical and research domains of nursing practice; (b) interoperability of technology can impact visualization; and (c) competencies are required to support mental imaging and use of technology in visualizing a whole and accurate picture.
