    This study investigated the integrated impact of Transformational Leadership (TFL), Cross-Sector Collaboration (CSC), and Foundations as Community Catalysts (CFC) within a Salem-based leadership institute. Through a qualitative case study involving 12 leadership institute attendees from 2020-2023, I explored the perceived presence of each of the three components, as well as their transformative potential in organizational and community change. I also examined participants’ perceived strengths and weaknesses of the leadership institute. All participants were able to see the presence of TFL, CSC, and CFC, and their combination resulted in collaboration, deep relationships, and a change in mindsets. The findings suggest that the TFL component of the programming fostered positive culture change and trust; that CSC aspects provided a space for trust and vulnerability, which facilitated meaningful and impactful changes in the community; and are all facilitated by the philanthropic approach of CFC involving deep and pure intent, a solid reputation and influence in the community. Among the most prominent community changes include the development of a behavioral health program within a career technical high school in the area, and the revitalization of a community-wide youth festival that had ended and lost funding several years ago. Participants also acknowledged that long-lasting impact takes time, but they were excited about the potential. Participants considered the strengths of the Leadership Institute to be valuable vulnerability/relationships, accountability, the ability to address community problems, the impactful retreat and monthly sessions, and alumni involvement/opportunities. Weaknesses included the desire for more time/going deeper, requesting greater demands on participants, a more specific organizational focus, concerns over long-term sustainability, and improved mentoring/coaching. This study lays the groundwork for future research, emphasizing the transformative potential of collaborative leadership, community engagement, and philanthropic initiatives. It underscores the impactful role of integrated leadership strategies in societal progress, advocating for ongoing research and application in varied settings to foster profound societal change

    AbstractThe problem of alcohol addiction is heightened when other psychological factors are present, such as the stress of acculturation. The purpose of this research was to describe the experiences of Christian African immigrants in America who have used faith-based treatment approaches while in recovery from alcoholism and to determine how their faith may have been a way of coping with their recovery. In this hermeneutic qualitative phenomenological study, data were collected through semi-structured interviews with eight participants. The data were analyzed to explore the experiences of Christian African acculturating to America who endorse a faith-based approach to their recovery, and the following three main categories emerged: (a) acculturation stress and its relationship to alcoholism; (b) factors that affected recovery; and (c) integrating psychological, spiritual, and medical factors in recovery. In addition, 13 subcategories emerged: (a) job and settlement stress; (b) using alcohol to cope; (c) stress from helping people at home country; (d) culture shock, accent, communication, and respect differences; (e) social drinking/peer pressure; (f) family support; (g) church and related activities support; (h) personal faith/spiritual growth support; (i) spiritual leaders and relationship support; (j) role of spirituality; (k) the place of psychology and therapy; (l) the role of medication; and spiritual support system. The findings of this research will provide a better understanding of the experiences of participants who have endorsed faith as crucial to their recovery. This has potential implications for positive social change by providing a clearer understanding of this phenomenon, which can help with addiction counseling, especially for the population of the study

    Fantasia on a Theme of Purpose: Using a Music-Guided Scribble Technique to Support Meaning-Making in Older Adult Retiree Musicians

    Get PDF
    Within the population of older adults, overall well-being corresponds with the ability to self-actualize and seek meaning, but age-related changes combined with ageism and isolation can negatively impact this capacity to maintain a sense of purpose, especially following retirement. It may be that retired musicians are especially vulnerable to this experience later in life due to a loss of the primary method of creative engagement and community that is facilitated by musical performance in a group setting. Integrating phenomenological and ethnographic approaches, this study utilized a qualitative design to understand how music-guided art-making incorporating the scribble technique could support a sense of purpose among older adult retiree musicians. In an art-based intervention that collected art and interview data, participants responded to self-selected music with a variety of fluid and resistive drawing materials categorized as Media Dimension Variables (MDV). Data analysis was executed in conjunction with theories of Acceptance and Commitment Therapy (ACT) and the Expressive Therapies Continuum (ETC). Results obtained via thematic analysis suggested that the intervention facilitated access to creative intentionality in support of a sense of purpose. The process of self-selecting music that was rich with personal significance provided an optimal frame of reference in a novel art experiential that engaged individual strengths, values, and expertise. Responding to music in real-time with a kinesthetically-focused drawing technique presented a non-threatening approach to visual composition; the spontaneity in this process also offered opportunities for self-discovery and contact with the present moment

    Effective digital support for autism: digital social stories

    Social Stories™ is one of the most popular interventions for autistic children and has been researched extensively. However, effectiveness data has been gathered mainly through single-participant designs which generate outcomes which can lack generalizability and social validity. Stories Online For Autism (SOFA) is a digital application which supports the development and delivery of Social Stories in a real-world setting and has the potential to contribute toward furthering (1) Social Stories research and (2) research on digital applications for autism by gathering large data sets from multiple participants. Three data sets (N = 856) were gathered through the SOFA app and were analyzed to investigate three key variables: What predicted closeness-to-goal of the Social Stories (as rated by an adult/parent/guardian, n = 568); the child’s comprehension of the Social Stories (assessed by story comprehension questions, n = 127); and the child’s rating of the enjoyability of the Social Stories (n = 161). A merged data set then investigated correlations between these three key variables. Age range (≤15), gender, autism diagnosis, and the child’s level of language understanding were the potential predictors for these three key variables. Regression analysis indicated that parental closeness-to-goal ratings for their children were highest for children who were younger and more verbal. Regression analysis also indicated that older children scored higher in comprehension assessment, and autistic children rated the Social Stories as more enjoyable. Closeness-to-goal, comprehension scores and enjoyment ratings did not significantly correlate with each other. This is the largest study of Social Stories effectiveness, which was enabled through the collection of data through a digital app from multiple participants. The results indicate that digital social stories are particularly effective for younger verbal children. While this was the case for all children, it was particularly true for autistic children and female (and gender-diverse) children. For the first time, the gathering of large digital data sets has highlighted that while digital Social Stories can be effective for autistic males, they can be more effective for autistic females and gender-diverse autistic individuals. Thus, the SOFA app can support the investigation of the factors which influence Social Stories outcomes that are generalizable and with high social validity

    Objective: To investigate the potential of deep learning for automatically delineating (segmenting) laryngeal cancer superficial extent on endoscopic images and videos. Methods: A retrospective study was conducted extracting and annotating white light (WL) and Narrow-Band Imaging (NBI) frames to train a segmentation model (SegMENT-Plus). Two external datasets were used for validation. The model's performances were compared with those of two otolaryngology residents. In addition, the model was tested on real intraoperative laryngoscopy videos. Results: A total of 3933 images of laryngeal cancer from 557 patients were used. The model achieved the following median values (interquartile range): Dice Similarity Coefficient (DSC) = 0.83 (0.70-0.90), Intersection over Union (IoU) = 0.83 (0.73-0.90), Accuracy = 0.97 (0.95-0.99), Inference Speed = 25.6 (25.1-26.1) frames per second. The external testing cohorts comprised 156 and 200 images. SegMENT-Plus performed similarly on all three datasets for DSC (p = 0.05) and IoU (p = 0.07). No significant differences were noticed when separately analyzing WL and NBI test images on DSC (p = 0.06) and IoU (p = 0.78) and when analyzing the model versus the two residents on DSC (p = 0.06) and IoU (Senior vs. SegMENT-Plus, p = 0.13; Junior vs. SegMENT-Plus, p = 1.00). The model was then tested on real intraoperative laryngoscopy videos. Conclusion: SegMENT-Plus can accurately delineate laryngeal cancer boundaries in endoscopic images, with performances equal to those of two otolaryngology residents. The results on the two external datasets demonstrate excellent generalization capabilities. The computation speed of the model allowed its application on videolaryngoscopies simulating real-time use. Clinical trials are needed to evaluate the role of this technology in surgical practice and resection margin improvement. Level of evidence: III Laryngoscope, 2024

    Exploring the impact of food composition and eating context on food choice, energy intake and body mass index

    Get PDF
    Research suggests that traditional behaviour-based weight loss approaches requiring individuals to change their dietary habits or physical activity results in only modest weight loss which often isn’t maintained. Given the need to improve population health, the broader food environment (e.g., food price or composition) and the more immediate eating context have been identified as possible intervention targets.For product reformulation to be a successful public health strategy, consumers are required to be ‘insensitive’ to changes to the reformulated product. This raises a more general question regarding whether humans are sensitive to food composition and whether this influences food choice and energy intake. The studies presented in Part A suggest that people are sensitive to both the energy content and macronutrient composition of food. Specifically, the results presented in chapters two to four indicate a non-linear pattern in meal caloric intake in response to meal energy density (kcal/g), and this pattern was captured in a theoretical two-component model of meal size (g, chapter five). The remaining two chapters in Part A (chapters six and seven) explore human sensitivity to food macronutrient composition. Chapter six describes the development of a new paradigm and task to assess protein discrimination by humans. Chapter seven focuses on the remaining two macronutrients, fat and carbohydrate, and demonstrates that, alongside being more liked, foods containing a combination of fat and carbohydrate are selected in larger portions than foods high in either fat or carbohydrate.The effect of eating contexts (e.g., social or distracted eating) on acute energy intake is well-researched, but their chronic impact on energy balance is unclear. The results of chapter nine (Part B) indicated that more frequently watching TV was associated with a higher body mass index (BMI) in young adults. More generally, the work identified eating contexts as potential targets for public health messaging which could effect changes in BMI on a population level. Together, the work presented in this thesis highlights new complexity in human dietary behaviour which presents both challenges and opportunities for successful food reformulation as a public health strategy, and it also demonstrates that the context in which we eat our meals could be leveraged to improve population-level health

    A Phenomenological Study Exploring the Factors That Contribute to Persistence in Online Doctoral Programs for Students With Learning Disabilities or ADHD

    The purpose of this transcendental phenomenological study was to discover the factors that contributed to persistence in online doctoral programs for students with learning disabilities (LD) and attention deficit hyperactivity disorder (ADHD). The theory guiding this study was Tinto’s theory of student persistence, as it suggested the more students were academically and socially integrated into their institution, the more likely they were to persist in their studies. The Central research question of this study is, “What are the factors that contribute to persistence in online doctoral programs for students with LD and ADHD?” Participants in this study consisted of seven individuals with learning disabilities or ADHD who had completed all of their required coursework in their current online doctoral program and had started the dissertation phase of their program, and four who had graduated from their online doctoral programs within the last two years. Candidates were selected using purposive sampling. Perspectives of students with LD and ADHD as they related to their academic persistence were shared. The lived experiences of online doctoral students with LD and ADHD were studied using online discussion board prompts, individual interviews, and focus groups. The data were collected and analyzed using Moustakas’ transcendental phenomenology approach and generated six themes and commonalities among the participants in this study. The themes were Overcoming Challenges and Barriers, Adaptation and Coping Strategies, Motivation, Self-Efficacy, Support Systems, and Personal Determination and Perseverance. The data analysis revealed empirical, practical, and theoretical implications along with recommendations for future research
