Religious actors in conflict management : Where and how can they be most effective?

Prieto Pérez, Fausto January 2023 (has links)
Criticism of the role of religious actors in conflict management rests primarily on the premise that evidence produced is largely anecdotal due to the lack of a theoretical underpinning that permits thorough analysis. As such, the added value of religious actors as practitioners is difficult to recognise officially and quantify. This research aims to explore the possibility of developing a theoretical framework that would eventually bestow appreciation of their role, as well as allow comparison across similar interventions, and facilitate resource distribution to those projects likely to have a bigger positive impact. A preliminary theoretical framework is proposed by reviewing the existing literature and contrasting with feedback from semi-structured interviews undertaken with professional practitioners working on an on-going peace project in Ethiopia. Further research, experimentation and expert discussion, systematically testing each of the components, will be needed in order to hone the framework to a functional and effective tool.

[pt] CONSELHOS CONSERVADORES E GESTORES INTRÉPIDOS: A INTERAÇÃO ENTRE GOVERNANÇA CORPORATIVA, LATITUDE GERENCIAL E COMPORTAMENTO FINANCEIRO AO LONGO DE DOIS FAMOSOS ENIGMAS FINANCEIROS / [en] CONSERVATIVE BOARDS AND INTREPID MANAGERS: THE INTERPLAY OF CORPORATE GOVERNANCE, MANAGERIAL DISCRETION AND FINANCING BEHAVIOR ALONG TWO FAMOUS FINANCIAL PUZZLES

MICHAEL ESPINDOLA ARAKI 28 May 2020 (has links)
[pt] Nesta tese, utilizo uma perspectiva teórica que integra as teorias tradicionais de finanças às teorias de empreendedorismo e criatividade para investigar o comportamento das empresas ao longo de dois famosos enigmas financeiros: a alavancagem zero e a sensibilidade do investimento ao fluxo de caixa. Particularmente, eu exploro e desenvolvo dois construtos — rule-taking e risk-taking — que existem na interface entre governança corporativa e tomada de decisão gerencial sob incerteza, e que têm uma influência significativa nas decisões de estrutura de capital e de investimento. O rule-taking é um novo construto que reflete o grau em que um gestor é passível de controle externo, intervenção ou tem seu poder decisório restrito. O risk-taking, embora não seja um novo construto, é reexaminado através de uma lente teórica mais abrangente, que engloba as ideias da teoria da criatividade e os conceitos de incerteza knightiana e do estar alerta kirzneriano. Assim, tais construtos servem como o nexo para investigar os famosos enigmas financeiros, indo além das vertentes financeiras tradicionais (e.g., a teoria do trade-off; Modigliani e Miller, 1958) e das vertentes gerenciais tradicionais (e.g., a teoria da agência; Jensen e Meckling, 1976) para analisar as relações negligenciadas entre governança corporativa e a intrepidez do gestor em ambientes competitivos, complexos e incertos. A tese é composta por três artigos autônomos, além de uma introdução comum e uma discussão geral. O primeiro artigo é um ensaio teórico no qual eu problematizo o paradigma dominante da governança corporativa (teoria da agência) e desenvolvo o embasamento teórico para os construtos de rule-taking e risk-taking. O segundo e o terceiro artigo são estudos empíricos que investigam se esses construtos podem ajudar a explicar, respectivamente, o enigma das empresas com alavancagem zero, e a sensibilidade do investimento ao fluxo de caixa. Os resultados em grande parte corroboram as hipóteses. Assim, este trabalho expande a discussão sobre temas tradicionais relacionados a finanças corporativas e governança corporativa, reunindo perspectivas sub-representadas na literatura financeira, decorrentes de diferentes áreas de pesquisa, como empreendedorismo e criatividade, e demonstrando que elas podem acrescentar ideias novas e úteis para pesquisa e prática. Finalmente, esta tese também é uma resposta a chamados recentes para a utilização de abordagens mais integrativas e multidisciplinares com o fim de melhor analisar o comportamento da empresa. / [en] In this dissertation, I utilize a theoretical perspective that integrates traditional finance theories with the entrepreneurship and creativity theories to investigate the behavior of firms along two conspicuous financial puzzles: the zero-leverage puzzle and the sensitivity of investment to cash flows. Particularly, I explore and develop two constructs—rule-taking and risk-taking—that exist at the interface of corporate governance and managerial decision-making under uncertainty and which are hypothesized to have a significant bearing on capital structure and investment decisions. Rule-taking is a novel construct that reflects the degree to which a manager is liable to external control, intervention or have their discretionary power constrained. Risk-taking, although not a novel construct, is re-examined through a more comprehensive theoretical lens that encompasses the insights from creativity theory and the concepts of Knightian uncertainty and Kirznerian alertness. These constructs, then, serve as the nexus to investigate the financial puzzles going beyond both traditional finance strands (e.g., the trade-off theory; Modigliani and Miller, 1958) and traditional managerial strands (e.g., agency theory; Jensen and Meckling, 1976) to analyze overlooked relationships between corporate governance and managerial intrepidness in competitive, complex and uncertain environments. The dissertation is composed of three stand-alone papers, with a unified introduction and a general discussion. The first paper is a theoretical essay in which I problematize the dominant paradigm of corporate governance (agency theory) and develop the theoretical background for the constructs of risk-taking and rule-taking. The second and third papers are empirical studies that investigate whether these constructs can help explain the puzzles of zero-leverage firms and investment-cash flow sensitivity, respectively. The results mainly support the hypotheses. This work, then, expands the discussion on traditional themes related to corporate finance and corporate governance by bringing together underrepresented perspectives in the finance literature, stemming from different areas of research, such as the entrepreneurship and creativity literature strands, and demonstrating that they can add novel and useful insights for research and policy. Finally, this dissertation also answers recent calls for the utilization of more integrative and multidisciplinary approaches to further analyze firm behavior.

Faktorer som påverkar en miljöinvestering / Factors that are affecting an environmental in-vestment

ELNER, FREDRIK January 2012 (has links)
Syftet med detta examensarbete är att göra en jämförande studie mellan faktorerna som enligt en teoretisk ram påverkar en miljöinvestering och faktorerna som ingår i ett företags bedömnings-modell. Respondentbolaget begärde i ett tidigt skede att få vara anonymt och benämns därför som Företaget. Det är en multinationell koncern med verksamhet i många skilda branscher, men med fokus på norden och produkter som kan kopplas till lantbruk. Den teoretiska referensramen har sin utgångspunkt i begreppen värde och investering samt hur deras koppling till miljö och miljöinvesteringar för att identifiera de faktorer som påverkar en miljöinvestering. Faktorerna som ingår i den teoretiska referensramen och som jämförs mot respondentbolagets faktorer är:  Investeringens värdetillförsel  Investeringens miljöpåverkan  Hur investeringen påverkar produktionsförutsättningarna  Krav från samhället  Kundkrav Kopplingen däremellan bedöms enligt en femgradig skala. Informationen från Företaget inhäm-tades genom semi-strukturerade intervjuer med representanter från Företaget. Slutsatsen för detta arbete är att Företaget har identifierat samma faktorer som den teoretiska referensramen. De använder dock mätetal som inte fullt ut reflekterar faktorerna. Den största avvikelsen är bedömningen av en investerings värdetillförsel, då Företaget fullt ut införlivar det producerade värdet samt det faktum att en miljöinvestering skall ses som irreversibel. Enkelhet premieras hos Företaget och det är för att prioritera modellens användbarhet, som Företaget väl-jer att acceptera brister i bedömningsmodellen. För att förbättra bedömningsmodellen bör Företaget därför införliva nya mätetal som till större del reflekterar faktorerna som påverkar en miljöinvestering / The purpose of this master thesis is to present a comparison between the factors that affects an environmental investment. This is done through applying a theoretical framework on the factors affecting a company’s existing appraisal model for environmental investments. The company that was a part of this thesis asked at an initial stage for confidentiality, therefore it is called the Company in this thesis. The Company that contributes with the appraisal model is a multination-al group with operations in many different industries, but with a focus on the Nordic countries and products that may be linked to the agricultural sector. The theoretical framework has its base in the concepts of value and investments and their connection to the environment and the envi-ronmental investment. The identified factors in the theoretical framework are:  The investment’s addition to the value creation to the company  The investment’s environmental impact  How the investment affects the production  Demands from society  Customer demands From these, the factors affecting a company’s existing appraisal model were compared and their connection to theoretical framework was judged according to a 5-grade scale. Information from the Company was acquired through semi-structured interviews with representatives from the Company. The largest deviation is how the company considers an investment’s contribution to the produced value. Because of this imperfection does the company's model not fully incorporate the produced value and that an environmental investment is irreversible. The overall conclusion is that the Company has identified the same factors as the theoretical framework. The Company has though chosen to use their existing methods and performance indicators that don’t fully incorporate the factors in the theoretical framework. The largest devia-tions are how the company considers an investment’s contribution to the produced value and that it should be considered as irreversible. The Company must therefore in order to enhance their appraisal model develop new performance measures for the factors.

Misconceptions regarding direct-current resistive theory in an engineering course for N2 students at a Northern Cape FET college / Christiaan Beukes

Beukes, Christiaan January 2014 (has links)
The aim of this study is to ascertain what misconceptions N2 students have about DC resistive circuits and how screencasts could effect on the rectification of these misconceptions. This study was conducted at the Kathu Campus of the Northern Cape Rural Further Education and Training College in the town Kathu in the arid Northern Cape. The empirical part of this study was conducted during the first six months of 2013. A design-based research (DBR) method consisting of four phases was used. DBR function is to design and develop interventions such as a procedure, new teachinglearning strategies, and in the case of this study a technology-enhanced learning (TEL) tool (screencast) with the purpose of solving a versatile didactic problem and to acquire information about the interventions of the TEL tool (screencast) on the learning of a student. In the first and second phase of DBR quantitative data for this research were gathered with the Determining and Interpreting Resistive Electric circuits Concepts Test (DIRECT) in order to determine the four most common misconceptions. The DIRECT test was conducted in the first trimester to find the misconceptions; the test was conducted in the second trimester also to confirm the misconceptions. Further quantitative data were collected from a demographic questionnaire. The qualitative data were collected by individual interviews in the fourth phase of the research project. Phase three of this study was the development of screencasts in the four most prominent misconceptions in DC resistive circuits of the students. The respondents of this study were non-randomly chosen and comprised of two groups, one in the first trimester of the year and one in the second trimester of the year, which enrolled for the N2 Electrical or Millwright courses. The respondents were predominant male and representing the three main cultural groups in the Northern Cape namely: Black, Coloured and White. The four misconceptions on DC resistive circuits that were identified were: (i) understanding of concepts, (ii) understanding of short circuit, (iii) battery as a constant current source, and (iv) rule application error. Screencasts clarifying the four misconceptions were developed and distributed to the respondents. On the foundation of the results of this research, it can be concluded that the students have several misconceptions around direct current resistive direct current circuits and that the use of TEL like screencasts can be used to solve some of these misconceptions. Screencasts could supplement education when they were incorporated into the tutoring and learning for supporting student understanding. The results of this research could lead to the further development and refinement of screencasts on DC resistive circuits and also useable guidelines in creating innovative screencasts on DC resistive circuits. / MEd (Curriculum Development), North-West University, Potchefstroom Campus, 2014

Collaborative Partnerships to Assist in Managing Adult-Onset Diabetes in Cameroon

Forju, Jingwa Christopher 01 January 2019 (has links)
Increasing rates of adult-onset diabetes in low- to middle-income countries (LMICs) present a growing healthcare concern that requires a regulatory approach and local community engagement. Cross-sector collaboration (CSC) is an effective strategy for improving community health. CSC is not effectively used to manage adult-onset diabetes in LMICs, nor is there public policy advocating CSC in the management of diabetes. This qualitative exploratory case study explored how leadership and resources affect the use of CSC to assist in managing the adult-onset of diabetes in a CSC in Cameroon. A purposeful sampling strategy was used to identify participants for semistructured interviews of 10 executives involved in the CSC. CSC theory provided a theoretical framework. Collected data were organized by audio recording, transcribing, translating, member checking, and thematically coding data using NVivo 12 software. Data from a review of documents and researcher observations were triangulated with interview data. Findings revealed that poverty, access to health care, and rising diabetes prevalence contributed to environmental turbulence. Goal-setting and objectives, intersectoral-communication, fostering trust and respect, and sharing data and motivating people presented leadership effectiveness challenges. The following resource challenges emerged in the CSC: public policy, money, skills and expertise, equipment and supplies, and connection to the target population. This increased scientific understanding could help government policy-makers and nongovernmental organizations expand public policy leading to a decrease in the prevalence and burden of adult-onset diabetes.

The dynamics of learning partnerships : case studies from Queensland

Peirce, Heather Jean January 2006 (has links)
This study examines the emerging notion of learning partnerships. As the study of such partnerships is a nascent research field, no single definition has yet emerged in the literature. However, within an uncertain and rapidly changing global context, two strategic initiatives have been identified which will support individuals, communities and organisations in their transition to a knowledge-based economy whilst building capacity for change and renewal. These two strategies are fostering learning communities/regions/towns and developing learning partnerships between multiple stakeholders. The term "learning partnership" has appeared in a wide variety of literatures including those of adult learning, management, social science and education. Working papers and emerging case reports identify a diversity of applications and a range of operational models or configurations that link multiple stakeholders. Learning partnerships have been associated with vocational education and training, innovation and research, lifelong learning, organisational learning and knowledge cultivation. These literatures reveal a paucity of Australian research to explain how multiple stakeholders form and develop these configurations, particularly in the Queensland context. The purpose of this study is to build deeper understanding of the meaning of a learning partnership in the Australian and (more precisely) the Queensland context. A working definition of a learning partnership, adopted as the basis for the research, indicates a strategy designed to foster continuous learning, collaboration, innovation and renewal in response to the demands of the knowledge-based economy and knowledge and learning societies. The research focuses on organisational arrangements in order for the researcher to gain deeper understanding from the key stakeholders in their work environments. Three diverse situations were selected for detailed exploration of their issues, relationships, activities, processes and working knowledge. With a view to contributing to emerging theory, an organisational case study methodology was adopted to identify and explore the nature of the relationships and issues confronting the key stakeholders in three Queensland-based learning partnerships. An interpretive theoretical framework draws on the social theory of symbolic interactionism and the "systems thinking" of General Systems Theory. An interpretivist perspective influenced the case study research strategy and guided data collection, analysis and reporting. Within the case studies, data collection methods included observations, informal meetings, synergetic focus groups, semi-structured interviews, diary notes, researcher memos and documents. From these multiple data sources, the researcher was able to assemble three case files. The inductive process for within-case analysis for the case reports, and later, cross-case analysis, integrated as a form of constant comparison technique, was used as a basis for presenting findings. These findings are reported as three separate "in progress" models to address three interrelated research questions. The case reports explain complex and interconnected organisational arrangements - evolving, adapting and responding to internal and external tensions. While there is considerable activity which could be regarded as representing learning partnerships, there is no cohesive policy framework to support such partnerships, and much ambiguity, "muddy" definitions and unclear terminology. It appears that a "new breed" of knowledge-worker is emerging - linking, networking, interacting, exchanging - to work across organisational intersections. The study shows that like "herding cats", co-ordinating and managing the inter relationships at the organisational intersection take time, resources, vision, processes for interaction, individual willingness and "in-kind" support. Whilst there is opportunity for linking disparate groups to cross-fertilise ideas, working knowledge, and information, and there is the potential to cultivate a knowledge and learning ecosystem (a fertile compost heap for knowledge generation and an innovative learning system) - "intellectual horsepower" - such configurations may also derail, realign or stagnate. It is individual stakeholders who form the relationships, interact, share ideas, and build networks, and it is the individual who maintains the relationships, engages in the process and learns from the experience. Therein lies a paradox between the strength of diversity of the collective (synergies) and their weakness as the relationships may be compromised by a single individual who withdraws or transfers. Drawing on a computing analogy, this could be akin to "corruption" in a system which may not be sufficiently robust to tolerate ambiguity, or a system that is too inflexible to survive threats while maintaining the momentum to adapt and renew. On the basis of this research it would appear that a more robust or resilient paradigm is emerging with interconnected, blurred boundaries and much "talking and thinking" about more sustainable futures. The study identifies these as indicative of wider social and economic changes. The thesis proposes three conceptual models as particularly useful in interpreting these "shifting systems and shifting paradigms": the concentric, the centripetal, and the plutonic.
