An Examination Of Leading Through Change Using Snyder’S Hope Theory And Lewin’S 3-Step Model, Scott E. Sorensen

Theses and Dissertations

Never has the world experienced such rapid change, and the environment in which organizations operate necessitates increased change capability and organizational agility (Argyris, 1991). Strebel (1996) found success rates for change initiatives in Fortune 1000 companies ranged from a low of 20% to a high of 50%. Later studies would substantiate Strebel’s (1996) findings, claiming that, on average, failure rates of transformational change initiatives approach 70% (Beer & Nohria, 2000; Sirkin et al., 2005). Suppose this is so, and companies wish to thrive in such a dynamic environment. A fundamental understanding of why change efforts fail and how to drive …

Let’S Practice: Shaping Crisis Management Of Preservice Counseling Professionals, Yuleinys A. Castillo, Jason Cartwright, Mandy Greaves, Suzanne Maniss

Counseling Faculty Publications

Counselors frequently encounter crises in practice with various factors shaping crisis management. However, limited preparation and training combined with personal and situational characteristics affect a counselors’ ability to properly handle a crisis. The purpose of the present study was to identify factors that could potentially affect the ability to handle a crisis in session among counselors-in-training and add to the understanding of self-efficacy in crisis counseling. The study consisted of participants enrolled in a practicum pre-service course in a CACREP accredited program. Results were analyzed through a narrative research approach, specifically a categorical-content narrative analysis, theory-driven thematic analysis and cross-case …

The Relationship Between Systems Thinking By Building Leaders And Academic Outcomes For Marginalized Students, Dunham Obadiah

Education Dissertations

Despite the attempts by lawmakers to legislate a closing of the achievement gap, persistent gaps in performance for students based on ethnicity, race, economic level, disability, and first language persist throughout public schools in the United States. Occasionally, a principal will receive attention for raising the performance of minoritized groups in their school. However, while admired, the principal’s efforts are not easily replicated. Furthermore, principal development programs fail to produce building leaders that can reliably achieve the change marginalized communities need.

There have been numerous studies that have shown that principals impact the academic performance of their students. For the …

Promotion To Fire Officer: Ems Is An Essential Component Of Promotional Testing, Brenda Kay Farlow

Walden Dissertations and Doctoral Studies

AbstractFor the past 25 years, the number of fire department responses to structure fires nationally has gone down. Structure fires now reflect less than ten percent of the responses of the fire service. In the same period, emergency medical services (EMS) have become the overwhelming activity of most fire departments. The problem is the promotional process focuses on firefighting knowledge and skills while ignoring the absolute need for EMS competencies, in some capacity, for a supervisory position. The lack of change in the promotional process is related to the organizational culture of the individual fire departments and the collective difficulty …

University Faculty Perceptions Of Mandatory Online Training As Related To Training Self-Efficacy, Motivation, And Utility, Tori Austin

Graduate Research Theses & Dissertations

Organizations spend millions of dollars training employees in ways to improve their skills –recently through mandatory professional development delivered virtually or through online asynchronous platforms. This research investigated how social exchange theory and self-efficacy theory inform faculty participants’ motivation to transfer such knowledge and skills from mandatory online trainings into their workplace practices. Faculty who had attended mandatory online training were asked to complete a 25-item survey about their motivation to transfer information from the training into their workplace practice as well as their perceived utility of training and their training self-efficacy. This study examined the extent to which motivation …

District-Level Supervisors: Leaders And Advocates For School Counseling, Thomas M. Mitchell

Theses and Dissertations

All school counselors are expected to serve as leaders and advocates in their school communities. However, many are underprepared for the work after they complete graduate-level training. The present study explored the experiences of district- level school counseling supervisors in facilitating leadership development with professional school counselors. District-level supervisors are ideally placed to support school counselors in their leadership development and advocacy work. Through a semi- structured interview process, eight district-level school counseling supervisors provided information about their leadership development experiences. Data analysis yielded four themes in this descriptive phenomenological study involving social justice, role advocacy, barriers to effective leadership, …

Strategies For Maximizing The Use Of Electronic Health Records Systems In Medical Clinics, Alexandra Nieves Rivera

Walden Dissertations and Doctoral Studies

Ineffective leadership can negatively impact the use of electronic health records (EHR) systems in medical clinics. Healthcare managers who fail to maximize the use of EHR systems are missing out on the opportunity to optimize the quality of medical care that their clinic provides. Grounded in complexity leadership theory, the purpose of this qualitative multiple-case study was to explore strategies healthcare managers use to maximize the use of EHRs systems. Participants comprised six healthcare managers who successfully implemented strategies to maximize the use of EHRs systems. Data were collected from semistructured interviews and publicly available information. Thematic analysis was used …

Sustainability Leadership: An Integrative Review And Conceptual Synthesis, Aymen Sajjad, Gabriel Eweje, Muhammad M. Raziq

Research outputs 2022 to 2026

Over the past few decades, scholars have extensively investigated the topic of leadership, contributing to the development of diverse leadership theories and contemporary managerial practice. However, the emergence and renewed focus on societal grand challenges warrant an alternative approach to leadership such as sustainability leadership. Despite the critical importance of sustainability leadership in addressing these global concerns, scholarly research in this field of inquiry, by and large, remained scant and fragmented, lacking conceptual coherence and theoretical integration. While the existing literature provides insights into sustainability leadership characteristics, competencies, behaviors, and actions, it failed to integrate a holistic understanding of how …

Habitual Dietary Nitrate Intake And Cognition In The Australian Imaging, Biomarkers And Lifestyle Study Of Ageing: A Prospective Cohort Study, Anjana Rajendra, Nicola P. Bondonno, Kevin Murray, Liezhou Zhong, Stephanie Rainey-Smith, Samantha Gardener, Lauren Blekkenhorst, David Ames, Paul Maruff, Ralph Martins, Jonathan M. Hodgson, Catherine P. Bondonno, Australian Imaging, Biomarkers And Lifestyle Group

Research outputs 2022 to 2026

Background & aims

Dietary nitrate improves cardiovascular health via a nitric oxide (NO) pathway. NO is key to both cardiovascular and brain health. There is also a strong association between vascular risk factors and brain health. Dietary nitrate intake could therefore be associated with better cognitive function and reduced risk of cognitive decline. This is yet to be investigated. The aim of this study was to investigate the association between habitual intake of dietary nitrate from sources where nitrate is naturally present, and cognitive function, and cognitive decline, in the presence or absence of the apolipoprotein E (APOE) …

Impact Of Vascular Screening Interventions On Perceived Threat, Efficacy Beliefs And Behavioural Intentions: A Systematic Narrative Review, Reindolf Anokye, Ben Jackson, James Dimmock, Joanne M. Dickson, Mary A. Kennedy, Carl J. Schultz, Lauren C. Blekkenhorst, Jonathan M. Hodgson, Mandy Stanley, Joshua Lewis

Research outputs 2022 to 2026

Health-related behaviours contribute to the global burden of cardiovascular disease (CVD). Cardiovascular imaging can be used to screen asymptomatic individuals for increased risk of CVD to enable earlier interventions to promote health-related behaviours to prevent or reduce CVD risk. Some theories of behaviour and behaviour change assume that engagement in a given behaviour is a function of individual threat appraisals, beliefs regarding the performance of behaviour, self-efficacy for performing the desired behaviour and/or dispositions to act (e.g. behavioural intentions). To date, little is known about the impact of cardiovascular imaging interventions on these constructs. This article summarises evidence related to …

A Potential Role For Sirtuin-1 In Alzheimer's Disease: Reviewing The Biological And Environmental Evidence, Mehrane Mehramiz, Tenielle Porter, Eleanor K. O'Brien, Stephanie R. Rainey-Smith, Simon M. Laws

Research outputs 2022 to 2026

Sirtuin-1 (Sirt1), encoded by the SIRT1 gene, is a conserved Nicotinamide adenine dinucleotide (NAD+) dependent deacetylase enzyme, considered as the master regulator of metabolism in humans. Sirt1 contributes to a wide range of biological pathways via several mechanisms influenced by lifestyle, such as diet and exercise. The importance of a healthy lifestyle is of relevance to highly prevalent modern chronic diseases, such as Alzheimer's disease (AD). There is growing evidence at multiple levels for a role of Sirt1/SIRT1 in AD pathological mechanisms. As such, this review will explore the relevance of Sirt1 to AD pathological mechanisms, by describing the involvement …

California State University (Csu) Police Department Leadership Evaluation, Berkeley Kijsriopas

Cal Poly Humboldt theses and projects

Leaders have the ability transform lives and societies and can motivate people for greatness or terrible things. Within a California State University police department, Chiefs of Police are important decision makers that can influence and shape the departments norms, values, goals, behaviors and attitudes. A leadership evaluation (N = 333), was used to explore the effects of leader prototypicality, officer self-uncertainty and social identity continuity through union leadership evaluations. The initial hypothesis that social identity continuity positively predicts group identification and is moderated by leader support was supported. However, the second hypothesis that the relationship between prototypical leaders and …
