A MULTIPLE CASE STUDY OF TWO PREDOMINANTLY AFRICAN AMERICAN YOUTH CHORAL ORGANIZATIONS

Trites, Andrew Thomas, 0009-0007-3816-5168 05 1900 (has links)
The purpose of this multiple case study was to explore stakeholders’ perspectives of two predominantly African American community youth choral organizations. My research questions included: (1) How do participants describe their experiences with the organization?, (2) What benefits and challenges do participants illuminate inside the organization and within the surrounding communities?, and (3) What future do participants envision for the organization within the surrounding communities? Systems thinking (Meadows, 2008; Stroh, 2015) and social systems perspective (Carter, 2011) shaped a conceptual lens that illuminated stakeholders’ perspectives. Each organization was selected because it was intrinsically interesting (Stake, 2005). Unlike many United States community youth choral organizations, these organizations provided academic support, meals, and door-to-door transportation for singers. Participant groups included staff, non-staff, and child singers. Data were collected over 18 weeks through observations of organizational events, including researcher written notes and transcribed voice memos, anonymous online questionnaires for adult participants, individual interviews with adult participants, and focus groups with child singers. Across both organizations, I collected 37 notes from observations, 17 anonymous questionnaires, 18 adult interviews, and nine focus groups with 21 child singers. I analyzed data through the constant comparative method (Glaser & Strauss, 1999), and verified the data analysis through triangulation between data forms and stakeholder groups (Stake, 2005), prolonged engagement and persistent observation (Lincoln & Guba, 1985), and peer coding. Findings from each case included a rich description of the organization, a narrative describing a child singer’s typical day, an analysis of how each domain of community music programs emerged, benefits and challenges identified within and across participant groups, and participants’ future visions for the organization. The final chapter comprises a cross-case analysis, focused on a comparison of the cases including overlapping themes and discussion. In the cross-case analysis, participants’ experiences were largely positive, accentuating how unique these organizations were to their communities. Participants shared how the organizations achieved dynamic equilibrium through evolving to meet stakeholders’ interests and needs. Participants described these organizations as socially engaging through building relationships, feeling like family, traveling with the organization, and meaningful summer camps. Challenges included connecting stakeholders across racial identities and funding. Because staff leaders engaged stakeholders from an assets-based approach, these organizations serve as models for choral organizations engaging with marginalized communities. By involving child singers, their families, and broader stakeholders in decision-making. choral leaders across the United States may improve organizational responsiveness. Additionally, engaging with stakeholders through assets-based philosophies honors the diverse and sometimes contradictory experiences of stakeholders, especially those from marginalized backgrounds and identities. Suggestions for future research included using Schippers and Bartleet’s (2013) framework to analyze additional music organizations, Bartleet’s (2023) framework to evaluate organizational progress toward desired social outcomes, and systems thinking to promote asset-based solutions for music programs and organizations. / Music Education

Impact of Alternative Flow Control Policies on Value Stream Delivery Robustness Under Demand Instability: a System Dynamics Modeling and Simulation Approach

Sousa, George 23 November 2004 (has links)
This research explores the effect of proposed management policies and related structures on the dynamics of value streams, particularly under demand instability. It relies on methods from the systems thinking and modeling literature and was designed to fulfill three main objectives. Objective 1: Provide insight into the causes of problematic behavior in traditional value streams. Objective 2: Identify modes of demand behavior suitable for pull-based systems operation. Objective 3: Propose and test alternative value stream management policies and structures. The achievement of objectives 1 and 3 required the fulfillment of both a hypothetical and a real case. The hypothetical case was designed to describe the problem and improvement alternatives in generic terms, whereas the real case served to contextualize the main generic modeling elements in a real world situation, thus serving as an illustrative example. The research approach was one based on system dynamics modeling and simulation methodologies that reflect the scientific method. Three alternative policies were created and tested. Policy 1: a decision rule for altering the number of kanbans in circulation at the protective decoupling inventory during production cycles. Policy 2: a decision rule for defining the amount of demand to include in value stream schedules. Policy 3: a decision rule for setting a purposefully unbalanced downstream production capacity. The results suggest a benefit from the combined use of Policies 2 and 3 in the face of sudden demand peaks. Policy 1 is expected to provide minor benefits but also significantly increase the risk of upstream instability and therefore its use is not recommended. This study provides a causality perspective of the structure of value streams, and gives enterprise engineers new insights into the state-of-the-art in value stream design. / Ph. D.

Neuroscience for Engineering Sustainability: Measuring Cognition During Design Ideation and Systems Thinking Among Students in Engineering

Hu, Mo 16 January 2018 (has links)
Sustainability is inherently a complex problem that requires new ways of thinking. To solve grand challenges such as climate change, environmental degradation, and poverty, engineers cannot rely on the same models of thinking that were used to create these problems. Engineering education is therefore critical to advance sustainable engineering solutions. Improving education relies on understanding of cognition of thinking and designing for sustainability. In this thesis, a nascent neuroimaging technology called functional near-infrared spectroscopy (fNIRS) was used to measure cognition among engineering students thinking about sustainability. fNIRS provides an opportunity to investigate how sustainability in design influences cognition, and how different concept generation techniques help students consider many aspects related to sustainability. The first manuscript provides evidence that engineering students perceive sustainability in design as a constraint, limiting the number of solutions for design and decreasing the cognitive efficiency to generate solutions. Senior engineering students generated fewer solutions than freshmen, however, seniors were better able to cognitively manage the sustainability parameter with higher cognitive efficiency. The second manuscript investigates the cognitive difference when generating concepts using concept listing or concept mapping. The results indicate that concept mapping (i.e. intentionally drawing relationships between concepts) leads to more concepts generated. An increase in concepts during concept mapping was also observed to shift cognitive load in the brain from regions associated with process sequencing to regions associated with cognitive flexibility. This research demonstrates the feasibility of fNIRS applied in engineering research and provides more understanding of the cognitive requirements for sustainability thinking. / M. S.

Developing a Measure of Systems Thinking Competency

Grohs, Jacob R. 04 May 2015 (has links)
Institutions of higher education often promise to graduate individuals capable not only of excelling in their area of expertise but also qualified as exceptional leaders and citizens. Yet, what are the competencies needed from leaders in order to address the most challenging issues facing society? How would higher education cultivate the next generation of leaders for a world of problems we currently cannot solve, and how would it be determined if some graduates were 'more prepared' than others to face these challenges? This dissertation seeks to answer these questions through the work of two distinct manuscripts. The first argues that human processes for meaning-making play critical formative roles in the setting and solving of our most complex problems. In essence, that problem-solving can be considered as embodied acts of meaning-making. This link is made through analysis of Bruner's concept of narrative and highlights the importance played by naming and framing through one's unique perspective while attempting to interpret an ill-structured problem. The second manuscript develops a tool to measure 'systems thinking,' a competency that describes the sort of cognitive flexibility that might be beneficial for graduates to be emerging leaders capable of addressing critical societal issues. A framework for considering systems thinking competency is presented and used as the foundation of a scenario-based assessment tool. Results from a qualitative pilot study are shown as part of introducing the tool with primary findings: (a) the tool elicited meaningful data on each of the constructs for which it was designed; (b) emergent within each construct were possible means of characterizing the data that will allow for future study of variation across respondents. / Ph.

A whole system approach to increasing children's physical activity in a multi-ethnic UK city: a process evaluation protocol

Hall, Jennifer, Bingham, Daniel D., Seims, Amanda, Dogra, Sufyan A., Burkhardt, Jan, Nobles, J., McKenna, J., Bryant, M., Barber, Sally E., Daly-Smith, Andrew 20 December 2021 (has links)
Yes / Engaging in regular physical activity requires continued complex decision-making in varied and dynamic individual, social and structural contexts. Widespread shortfalls of physical activity interventions suggests the complex underlying mechanisms of change are not yet fully understood. More insightful process evaluations are needed to design and implement more effective approaches. This paper describes the protocol for a process evaluation of the JU:MP programme, a whole systems approach to increasing physical activity in children and young people aged 5-14 years in North Bradford, UK. This process evaluation, underpinned by realist philosophy, aims to understand the development and implementation of the JU:MP programme and the mechanisms by which JU:MP influences physical activity in children and young people. It also aims to explore behaviour change across wider policy, strategy and neighbourhood systems. A mixed method data collection approach will include semi-structured interview, observation, documentary analysis, surveys, and participatory evaluation methods including reflections and ripple effect mapping. This protocol offers an innovative approach on the use of process evaluation feeding into an iterative programme intended to generate evidence-based practice and deliver practice-based evidence. This paper advances knowledge regarding the development of process evaluations for evaluating systems interventions, and emphasises the importance of process evaluation. / Sport England’s Local Delivery Pilot - Bradford

Beyond Waste Management : Challenges to Sustainable Global Physical Resource Management

Singh, Jagdeep January 2016 (has links)
Current physical resource management (PRM) was investigated in a global perspective in this thesis, to gain a deeper understanding of its implications in a sustainability perspective. In particular, the main challenges to the current PRM system and the kinds of systemic changes needed for sustainable PRM were examined. In five separate studies, different theoretical and practical challenges to current PRM approaches were analysed. A descriptive literature review, causal loop diagrams and semi-structured interviews were performed to gather qualitative and quantitative inferences. Perspectives from industrial ecology, life cycle thinking, systems thinking and environmental philosophy were then applied to analyse global resource/waste management issues. The analysis resulted in an overview of the global ecological sustainability challenges to current PRM and identification of major challenges to the global waste management system. Causal loop diagrams were used to qualitatively analyse the structure and behaviour of production and consumption systems responsible for unintended environmental consequences of purposive actions to improve material and energy efficiencies. Ways in which resource quality could be maintained throughout the system of production and consumption systems were determined by identifying challenges facing product designers while closing the material loops. A planning framework was devised to operationalise the sustainable development demands in society, including production and consumption systems. A broader systems approach is proposed for future sustainable global PRM, focusing on ensuring societal functions within the human activity system. The approach involves designing and managing anthropogenic stocks of physical resources to reduce inflows of physical resources and outflows of wastes and emissions. Life cycle-based databases linking resource consumption with waste generation are needed for improved global PRM. / I denna avhandling undersöktes fysisk resursanvändning i ett globalt perspektiv, för att få en djupare förståelse av dess konsekvenser i ett hållbarhetsperspektiv. Framför allt undersöktes de största utmaningarna med den aktuella fysiska resurshanteringen och vilka typer av systemförändringar som krävs för en hållbar fysisk resurshantering. I fem studier analyserades olika teoretiska och praktiska utmaningar för den nuvarande fysiska resurshanteringen. Litteraturstudier, kausala loopdiagram och semistrukturerade intervjuer genomfördes för att samla kvalitativ och kvantitativ information. Perspektiv från industriell ekologi, livscykeltänkande, systemtänkande och miljöfilosofi tillämpades för att analysera globala resurs- och avfallshanteringsfrågor. Analysen resulterade i en översikt av den nuvarande fysiska resurshanteringens globala ekologiska hållbarhetsutmaningar och identifiering av stora utmaningar för den globala avfallshanteringen. Kausala loopdiagram användes för att kvalitativt analysera strukturen och beteendet hos de produktions- och konsumtionssystem som gör att ändamålsenliga åtgärder för att förbättra material- och energieffektivitet får oavsiktliga negativa miljökonsekvenser. Hur resurskvalitet kan upprätthållas i produktions- och konsumtionssystemen som helhet bestämdes genom att identifiera de utmaningar som produktdesigners möter när de sluter kretslopp av material. En planeringsmodell utformades för att operationalisera kraven på hållbar utveckling i samhället, bland annat produktions- och konsumtionssystem. Ett bredare systemtänkande föreslås för en hållbar global fysisk resursförvaltning i framtiden, med fokus på att säkerställa samhällsfunktioner inom det mänskliga aktivitetssystemet. Tillvägagångssättet innebär att utforma och hantera antropogena fysiska resurser i syfte att: minska inflödet av fysiska resurser; och utflödet av avfall och utsläpp. Livscykelbaserade databaser som länkar resursanvändning till avfallsgenerering behövs för att förbättra den globala fysiska resursförvaltningen. / <p>QC 20160516</p> / India4EU

Towards effective governance of information in a Brazilian agricultural research organisation

Rocha-Bello-Bertin, Patricia January 2014 (has links)
There are three different uses of the term 'information' in ordinary language: in the restricted sense, it means diverse types of material objects, such as data or documents ('information as thing'); alternatively, the term is used as in reference to the act of informing or becoming informed ('information as process'), or to equate to knowledge ('information as knowledge'). Each of these connotations represents a legitimate view of information in its own right, being equally significant to information-intensive organisations. The literature lacks studies that approach information from an integrative viewpoint, however. The purpose of this study was to explore and develop the notion of 'information governance' as an integrative, systemic approach to information in the context of research organisations. Soft Systems Methodology was used in a case study involving the Brazilian Agricultural Research Corporation. Qualitative data was gathered through in-depth interviews with researchers and information/knowledge managers, followed by a thematic, two-level analysis. From a 'macro level' of analysis (the wider Brazilian agricultural research system) it was found that, to solve increasingly complex research problems, collaborative, multidisciplinary networking is needed. On the other hand, competitive forces are continuously emanating from the systems of research steering, funds and resources' allocation, quality control, and recognition and reward. This conflict inhibits the collaborative sharing of 'information as thing' and 'as knowledge', disturbs internal communication flows and contributes to low levels of synergy and cross-departmental partnerships, ultimately affecting research outcomes. At a 'meso level' (the local practices and culture of agricultural knowledge production), different epistemic cultures were identified (named in vitro, in situ and in silico research), which respond differently to the opposing forces of collaboration and competition. Based on a deep understanding of the agricultural research system and underlying epistemic cultures, a framework for effective governance of information was developed. Action to improve the governance of information at Embrapa would involve nurturing an information culture that supports collaborative work. Given that interactions between researchers are determined by their individual pursuits and struggles, this would require a change in the corporate system of performance evaluation and reward, according to the different epistemic cultures.

Establishing a new biofuel crop using System Thinking

Bartle, Samantha 04 1900 (has links)
Thesis (MEng)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: The complexity of adopting a new crop-based biodiesel feedstock into South Africa given the prevailing environmental, economic and social concerns facing the country are addressed in this study by utilising a Systems Thinking approach. Solaris is a new variety of Tobacco developed specifically as an energy crop over the last twelve years by Italian companies Plantechno and Sunchem. Small-scale trials have been underway over the last year in the Loskop Valley farming community in the Limpopo Province of South Africa. These trials have been managed by the newly-formed local entity, Toboil (Pty) Ltd. In order to assess the viability of introducing Solaris into Loskop in terms of addressing the current diesel and electricity needs of the community and larger over-arching biofuel goals of South Africa, the full System Dynamic Modelling process was employed. This included significant research, stakeholder engagement, a Systems Thinking workshop as well as model development and simulation using the System Dynamics programming tool, Vensim. Following the simulation of various scenarios, it was determined that in order for Solaris implementation to have the greatest impact on the diesel and electricity independence desires of the community, as well as maximising job creation and avoided greenhouse gas emissions, the first five to ten years of implementation may only achieve low to moderate profitability. It was further concluded that if crop-based biofuels are to help meet the rural development goals of South Africa then significant investment and skills transfer is required. In order to address both of these, a modular development process is advocated and should be aided and mentored by members of the commercial farming industry. / AFRIKAANSE OPSOMMING: Die kompleksiteit van die aanvaarding van ‘n nuwe oes-gebaseerde bio diesel roumateriaal in Suid-Afrika in die heersende omgewings-, ekonomiese- en sosiale kommer wat die land ervaar, word in hierdie studie aangespreek deur gebruik te maak van ‘n Sistemiese Denke Benadering (Systems Thinking approach) Solaris is ‘n nuwe variasie Tabak wat deur twee Italiaanse maatskappye Plantechno en Sunchem oor die afgelope twaalf jaar spesifiek as ‘n bron van energie ontwikkel is. Kleinskaalse proewe is gedurende die afgelope jaar in die Loskop Vallei Landbougemeenskap in die Limpopo-provinsie van Suid-Afrika gedoen. Hierdie proewe word onder die toesig van die nuut gevormde plaaslike entiteit, Toboil (Pty) Ltd uitgevoer. Aansienlike navorsing, die aktiewe deelname van die onderskeie belanghebbende partye, ‘n Sistemiese Denke werkswinkel sowel as die ontwerp van ‘n simulasie model deur die gebruik van Sisteem Dinamieke Programerings program, naamlik Vensim, is ingespan om die lewensvatbaarheid van die moontlike aanplanting van Solaris te beoordeel. Die spesifieke gemeenskap se huidige behoeftes aan diesel en elektrisiteit sowel as Suid-Afrika se breër doelwitte aangaande bio-brandstowwe was as die grondslag gebruik waarop die volle Sistemiese Denke Benadering toegepas is. In Loskop omgewing was verskeie moontlike scenarios beproef en daar is op grond daarvan vasgestel dat ten einde die grootste moontlike inpak te maak op die afhanlikheid van diesel en elektrisiteit behoeftes van die gemeenskap, sowel as om die grootste moontlik werkskepping potensiaal te verwesenlik – terwyl die afskeiding van kweekhuis gasse verhoed word - die eerste vyf tot tien jaar van implementering baie lae winsgrens tot gevolg sal hê. Daar is ook verder afgelei dat afsienbare beleggings en opleiding benodig gaan word indien aangeplante bio-brandstowwe aangewend sou word om die landelike ontwikkelingsdoelwitte in Suid-Afrika te verwesenlik. Ten einde beide hierdie doelwitte aan te spreek, word ‘n modulêre ontwikkelings proses aanbeveel waar gevestigde lede van die kommersiële lanbou industrie, bystand en leierskap voorsien.

Towards an understanding of human behaviour for design action

Watson, Benjamin W. January 2011 (has links)
It can be shown that exceeding both utilitarian and hedonic needs of consumers leads towards greater satisfaction, delight and enduring consumer loyalty. If designers are to meet the progressively diverse needs of consumers, then access to consumer values, aspirations and the underlying logic of their social practice become increasingly important. If we accept that what people say, do and think are often different things, gaining access to these requirements is clearly a challenge. The challenge is not only concerned with how these requirements are accessed at source, through widely adopted ethnographically inspired techniques, but more towards how these requirements are communicated to the designer. There is a clear disconnect between the collection of consumer requirements and how these requirements are arranged and communicated as implications for design. This thesis details a governance framework for the output of ethnographically inspired research methods to provide an understanding of the arrangement and attributes a communication tool for ethnographic work should possess, particularly towards the more technical area of new product development. The framework bridges a gap between consumer research and design action, which may be used as an approach to facilitate innovation, targeted problem solving and offer creative direction for new product development. Following an exploratory review of the literature and a series of way-finding interviews with domestic appliance and consumer goods manufacturers, a pilot study was conducted to identify the philosophical and practical barriers faced by designers, when designing for consumer requirements beyond the functional. A detailed second level literature review explored the emergent themes and led towards a desktop review of over 30 different creative thinking design tools from the design & emotion movement, 24 different communication approaches for ethnographic work in design and a two year case study on communication within the design process.

Exploring Designs for a Process Prioritisation Method

Ohlsson, Jens January 2016 (has links)
Problem/Purpose: Process prioritisation is an ill-structured and complex problem that remains a mystery phase in business process management (BPM) research. More explorative approaches are called upon to tackle process management problems, to facilitate process innovation and to design new processes in dynamic environments. This dissertation aims (i) to design and evaluate a Prioritisation and Categorisation Method (PCM) for addressing process prioritisation problems; and (ii) to explore process innovation by disruptive technologies. Research methods: This research follows the design science research (DSR) paradigm. The design exploration and the engaged scholarship approaches are also adapted. The demonstration and evaluation of the Prioritisation and Categorisation Method have been conducted with case studies in large Swedish companies, i.e. Seco Tools and Ericsson. An empirical study of the impacts of disruptive technologies on process innovation was conducted at a large insurance company in Sweden. Results: This research has led to the design and evaluation of the PCM: a new context-aware, effective and holistic method for BPM. In addition, the lessons learnt from the insurance case deepened the understanding of the challenges that are faced by a company when exploring new capabilities (e.g. processes and IT) for future business. Such lessons also emphasise the necessity of configuring PCM based upon business contingencies and industry factors in process prioritisation. Contributions: This dissertation contributes a novel method to explore BPM in a holistic, yet flexible and effective way. The challenges identified in process innovations improve the configuration capabilities of the PCM through a deeper understanding of the dynamic capabilities within organisations (Capability Layer Model-CLM). This research contributes design knowledge to DSR in the forms of the PCM as an invention, and the three design principles for the PCM: design by holistics, design by commitments and design by explorations. The research is evaluated as good BPM and good design science research.
